GNU GENERAL PUBLIC LICENSE |
||||
Version 2, June 1991 |
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc. |
||||
675 Mass Ave, Cambridge, MA 02139, USA |
||||
Everyone is permitted to copy and distribute verbatim copies |
||||
of this license document, but changing it is not allowed. |
||||
|
||||
Preamble |
||||
|
||||
The licenses for most software are designed to take away your |
||||
freedom to share and change it. By contrast, the GNU General Public |
||||
License is intended to guarantee your freedom to share and change free |
||||
software--to make sure the software is free for all its users. This |
||||
General Public License applies to most of the Free Software |
||||
Foundation's software and to any other program whose authors commit to |
||||
using it. (Some other Free Software Foundation software is covered by |
||||
the GNU Library General Public License instead.) You can apply it to |
||||
your programs, too. |
||||
|
||||
When we speak of free software, we are referring to freedom, not |
||||
price. Our General Public Licenses are designed to make sure that you |
||||
have the freedom to distribute copies of free software (and charge for |
||||
this service if you wish), that you receive source code or can get it |
||||
if you want it, that you can change the software or use pieces of it |
||||
in new free programs; and that you know you can do these things. |
||||
|
||||
To protect your rights, we need to make restrictions that forbid |
||||
anyone to deny you these rights or to ask you to surrender the rights. |
||||
These restrictions translate to certain responsibilities for you if you |
||||
distribute copies of the software, or if you modify it. |
||||
|
||||
For example, if you distribute copies of such a program, whether |
||||
gratis or for a fee, you must give the recipients all the rights that |
||||
you have. You must make sure that they, too, receive or can get the |
||||
source code. And you must show them these terms so they know their |
||||
rights. |
||||
|
||||
We protect your rights with two steps: (1) copyright the software, and |
||||
(2) offer you this license which gives you legal permission to copy, |
||||
distribute and/or modify the software. |
||||
|
||||
Also, for each author's protection and ours, we want to make certain |
||||
that everyone understands that there is no warranty for this free |
||||
software. If the software is modified by someone else and passed on, we |
||||
want its recipients to know that what they have is not the original, so |
||||
that any problems introduced by others will not reflect on the original |
||||
authors' reputations. |
||||
|
||||
Finally, any free program is threatened constantly by software |
||||
patents. We wish to avoid the danger that redistributors of a free |
||||
program will individually obtain patent licenses, in effect making the |
||||
program proprietary. To prevent this, we have made it clear that any |
||||
patent must be licensed for everyone's free use or not licensed at all. |
||||
|
||||
The precise terms and conditions for copying, distribution and |
||||
modification follow. |
||||
|
||||
GNU GENERAL PUBLIC LICENSE |
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
||||
|
||||
0. This License applies to any program or other work which contains |
||||
a notice placed by the copyright holder saying it may be distributed |
||||
under the terms of this General Public License. The "Program", below, |
||||
refers to any such program or work, and a "work based on the Program" |
||||
means either the Program or any derivative work under copyright law: |
||||
that is to say, a work containing the Program or a portion of it, |
||||
either verbatim or with modifications and/or translated into another |
||||
language. (Hereinafter, translation is included without limitation in |
||||
the term "modification".) Each licensee is addressed as "you". |
||||
|
||||
Activities other than copying, distribution and modification are not |
||||
covered by this License; they are outside its scope. The act of |
||||
running the Program is not restricted, and the output from the Program |
||||
is covered only if its contents constitute a work based on the |
||||
Program (independent of having been made by running the Program). |
||||
Whether that is true depends on what the Program does. |
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's |
||||
source code as you receive it, in any medium, provided that you |
||||
conspicuously and appropriately publish on each copy an appropriate |
||||
copyright notice and disclaimer of warranty; keep intact all the |
||||
notices that refer to this License and to the absence of any warranty; |
||||
and give any other recipients of the Program a copy of this License |
||||
along with the Program. |
||||
|
||||
You may charge a fee for the physical act of transferring a copy, and |
||||
you may at your option offer warranty protection in exchange for a fee. |
||||
|
||||
2. You may modify your copy or copies of the Program or any portion |
||||
of it, thus forming a work based on the Program, and copy and |
||||
distribute such modifications or work under the terms of Section 1 |
||||
above, provided that you also meet all of these conditions: |
||||
|
||||
a) You must cause the modified files to carry prominent notices |
||||
stating that you changed the files and the date of any change. |
||||
|
||||
b) You must cause any work that you distribute or publish, that in |
||||
whole or in part contains or is derived from the Program or any |
||||
part thereof, to be licensed as a whole at no charge to all third |
||||
parties under the terms of this License. |
||||
|
||||
c) If the modified program normally reads commands interactively |
||||
when run, you must cause it, when started running for such |
||||
interactive use in the most ordinary way, to print or display an |
||||
announcement including an appropriate copyright notice and a |
||||
notice that there is no warranty (or else, saying that you provide |
||||
a warranty) and that users may redistribute the program under |
||||
these conditions, and telling the user how to view a copy of this |
||||
License. (Exception: if the Program itself is interactive but |
||||
does not normally print such an announcement, your work based on |
||||
the Program is not required to print an announcement.) |
||||
|
||||
These requirements apply to the modified work as a whole. If |
||||
identifiable sections of that work are not derived from the Program, |
||||
and can be reasonably considered independent and separate works in |
||||
themselves, then this License, and its terms, do not apply to those |
||||
sections when you distribute them as separate works. But when you |
||||
distribute the same sections as part of a whole which is a work based |
||||
on the Program, the distribution of the whole must be on the terms of |
||||
this License, whose permissions for other licensees extend to the |
||||
entire whole, and thus to each and every part regardless of who wrote it. |
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest |
||||
your rights to work written entirely by you; rather, the intent is to |
||||
exercise the right to control the distribution of derivative or |
||||
collective works based on the Program. |
||||
|
||||
In addition, mere aggregation of another work not based on the Program |
||||
with the Program (or with a work based on the Program) on a volume of |
||||
a storage or distribution medium does not bring the other work under |
||||
the scope of this License. |
||||
|
||||
3. You may copy and distribute the Program (or a work based on it, |
||||
under Section 2) in object code or executable form under the terms of |
||||
Sections 1 and 2 above provided that you also do one of the following: |
||||
|
||||
a) Accompany it with the complete corresponding machine-readable |
||||
source code, which must be distributed under the terms of Sections |
||||
1 and 2 above on a medium customarily used for software interchange; or, |
||||
|
||||
b) Accompany it with a written offer, valid for at least three |
||||
years, to give any third party, for a charge no more than your |
||||
cost of physically performing source distribution, a complete |
||||
machine-readable copy of the corresponding source code, to be |
||||
distributed under the terms of Sections 1 and 2 above on a medium |
||||
customarily used for software interchange; or, |
||||
|
||||
c) Accompany it with the information you received as to the offer |
||||
to distribute corresponding source code. (This alternative is |
||||
allowed only for noncommercial distribution and only if you |
||||
received the program in object code or executable form with such |
||||
an offer, in accord with Subsection b above.) |
||||
|
||||
The source code for a work means the preferred form of the work for |
||||
making modifications to it. For an executable work, complete source |
||||
code means all the source code for all modules it contains, plus any |
||||
associated interface definition files, plus the scripts used to |
||||
control compilation and installation of the executable. However, as a |
||||
special exception, the source code distributed need not include |
||||
anything that is normally distributed (in either source or binary |
||||
form) with the major components (compiler, kernel, and so on) of the |
||||
operating system on which the executable runs, unless that component |
||||
itself accompanies the executable. |
||||
|
||||
If distribution of executable or object code is made by offering |
||||
access to copy from a designated place, then offering equivalent |
||||
access to copy the source code from the same place counts as |
||||
distribution of the source code, even though third parties are not |
||||
compelled to copy the source along with the object code. |
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program |
||||
except as expressly provided under this License. Any attempt |
||||
otherwise to copy, modify, sublicense or distribute the Program is |
||||
void, and will automatically terminate your rights under this License. |
||||
However, parties who have received copies, or rights, from you under |
||||
this License will not have their licenses terminated so long as such |
||||
parties remain in full compliance. |
||||
|
||||
5. You are not required to accept this License, since you have not |
||||
signed it. However, nothing else grants you permission to modify or |
||||
distribute the Program or its derivative works. These actions are |
||||
prohibited by law if you do not accept this License. Therefore, by |
||||
modifying or distributing the Program (or any work based on the |
||||
Program), you indicate your acceptance of this License to do so, and |
||||
all its terms and conditions for copying, distributing or modifying |
||||
the Program or works based on it. |
||||
|
||||
6. Each time you redistribute the Program (or any work based on the |
||||
Program), the recipient automatically receives a license from the |
||||
original licensor to copy, distribute or modify the Program subject to |
||||
these terms and conditions. You may not impose any further |
||||
restrictions on the recipients' exercise of the rights granted herein. |
||||
You are not responsible for enforcing compliance by third parties to |
||||
this License. |
||||
|
||||
7. If, as a consequence of a court judgment or allegation of patent |
||||
infringement or for any other reason (not limited to patent issues), |
||||
conditions are imposed on you (whether by court order, agreement or |
||||
otherwise) that contradict the conditions of this License, they do not |
||||
excuse you from the conditions of this License. If you cannot |
||||
distribute so as to satisfy simultaneously your obligations under this |
||||
License and any other pertinent obligations, then as a consequence you |
||||
may not distribute the Program at all. For example, if a patent |
||||
license would not permit royalty-free redistribution of the Program by |
||||
all those who receive copies directly or indirectly through you, then |
||||
the only way you could satisfy both it and this License would be to |
||||
refrain entirely from distribution of the Program. |
||||
|
||||
If any portion of this section is held invalid or unenforceable under |
||||
any particular circumstance, the balance of the section is intended to |
||||
apply and the section as a whole is intended to apply in other |
||||
circumstances. |
||||
|
||||
It is not the purpose of this section to induce you to infringe any |
||||
patents or other property right claims or to contest validity of any |
||||
such claims; this section has the sole purpose of protecting the |
||||
integrity of the free software distribution system, which is |
||||
implemented by public license practices. Many people have made |
||||
generous contributions to the wide range of software distributed |
||||
through that system in reliance on consistent application of that |
||||
system; it is up to the author/donor to decide if he or she is willing |
||||
to distribute software through any other system and a licensee cannot |
||||
impose that choice. |
||||
|
||||
This section is intended to make thoroughly clear what is believed to |
||||
be a consequence of the rest of this License. |
||||
|
||||
8. If the distribution and/or use of the Program is restricted in |
||||
certain countries either by patents or by copyrighted interfaces, the |
||||
original copyright holder who places the Program under this License |
||||
may add an explicit geographical distribution limitation excluding |
||||
those countries, so that distribution is permitted only in or among |
||||
countries not thus excluded. In such case, this License incorporates |
||||
the limitation as if written in the body of this License. |
||||
|
||||
9. The Free Software Foundation may publish revised and/or new versions |
||||
of the General Public License from time to time. Such new versions will |
||||
be similar in spirit to the present version, but may differ in detail to |
||||
address new problems or concerns. |
||||
|
||||
Each version is given a distinguishing version number. If the Program |
||||
specifies a version number of this License which applies to it and "any |
||||
later version", you have the option of following the terms and conditions |
||||
either of that version or of any later version published by the Free |
||||
Software Foundation. If the Program does not specify a version number of |
||||
this License, you may choose any version ever published by the Free Software |
||||
Foundation. |
||||
|
||||
10. If you wish to incorporate parts of the Program into other free |
||||
programs whose distribution conditions are different, write to the author |
||||
to ask for permission. For software which is copyrighted by the Free |
||||
Software Foundation, write to the Free Software Foundation; we sometimes |
||||
make exceptions for this. Our decision will be guided by the two goals |
||||
of preserving the free status of all derivatives of our free software and |
||||
of promoting the sharing and reuse of software generally. |
||||
|
||||
NO WARRANTY |
||||
|
||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY |
||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN |
||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES |
||||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED |
||||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF |
||||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS |
||||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE |
||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, |
||||
REPAIR OR CORRECTION. |
||||
|
||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING |
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR |
||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, |
||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING |
||||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED |
||||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY |
||||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER |
||||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE |
||||
POSSIBILITY OF SUCH DAMAGES. |
||||
|
||||
END OF TERMS AND CONDITIONS |
||||
|
||||
Appendix: How to Apply These Terms to Your New Programs |
||||
|
||||
If you develop a new program, and you want it to be of the greatest |
||||
possible use to the public, the best way to achieve this is to make it |
||||
free software which everyone can redistribute and change under these terms. |
||||
|
||||
To do so, attach the following notices to the program. It is safest |
||||
to attach them to the start of each source file to most effectively |
||||
convey the exclusion of warranty; and each file should have at least |
||||
the "copyright" line and a pointer to where the full notice is found. |
||||
|
||||
<one line to give the program's name and a brief idea of what it does.> |
||||
Copyright (C) 19yy <name of author> |
||||
|
||||
This program is free software; you can redistribute it and/or modify |
||||
it under the terms of the GNU General Public License as published by |
||||
the Free Software Foundation; either version 2 of the License, or |
||||
(at your option) any later version. |
||||
|
||||
This program is distributed in the hope that it will be useful, |
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of |
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the |
||||
GNU General Public License for more details. |
||||
|
||||
You should have received a copy of the GNU General Public License |
||||
along with this program; if not, write to the Free Software |
||||
Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. |
||||
|
||||
Also add information on how to contact you by electronic and paper mail. |
||||
|
||||
If the program is interactive, make it output a short notice like this |
||||
when it starts in an interactive mode: |
||||
|
||||
Gnomovision version 69, Copyright (C) 19yy name of author |
||||
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. |
||||
This is free software, and you are welcome to redistribute it |
||||
under certain conditions; type `show c' for details. |
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate |
||||
parts of the General Public License. Of course, the commands you use may |
||||
be called something other than `show w' and `show c'; they could even be |
||||
mouse-clicks or menu items--whatever suits your program. |
||||
|
||||
You should also get your employer (if you work as a programmer) or your |
||||
school, if any, to sign a "copyright disclaimer" for the program, if |
||||
necessary. Here is a sample; alter the names: |
||||
|
||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program |
||||
`Gnomovision' (which makes passes at compilers) written by James Hacker. |

|
||||
This General Public License does not permit incorporating your program into |
||||
proprietary programs. If your program is a subroutine library, you may |
||||
consider it more useful to permit linking proprietary applications with the |
||||
library. If this is what you want to do, use the GNU Library General |
||||
Public License instead of this License. |

MySQL FLOSS License Exception |
||||
|
||||
The MySQL AB Exception for Free/Libre and Open Source |
||||
Software-only Applications Using MySQL Client Libraries (the |
||||
"FLOSS Exception"). |
||||
|
||||
Version 0.6, 7 March 2007 |
||||
|
||||
Exception Intent |
||||
|
||||
We want specified Free/Libre and Open Source Software (``FLOSS'') |
||||
applications to be able to use specified GPL-licensed MySQL client |
||||
libraries (the ``Program'') despite the fact that not all FLOSS |
||||
licenses are compatible with version 2 of the GNU General Public |
||||
License (the ``GPL''). |
||||
|
||||
Legal Terms and Conditions |
||||
|
||||
As a special exception to the terms and conditions of version 2.0 |
||||
of the GPL: |
||||
|
||||
1. You are free to distribute a Derivative Work that is formed |
||||
entirely from the Program and one or more works (each, a |
||||
"FLOSS Work") licensed under one or more of the licenses |
||||
listed below in section 1, as long as: |
||||
a. You obey the GPL in all respects for the Program and the |
||||
Derivative Work, except for identifiable sections of the |
||||
Derivative Work which are not derived from the Program, |
||||
and which can reasonably be considered independent and |
||||
separate works in themselves, |
||||
b. all identifiable sections of the Derivative Work which |
||||
are not derived from the Program, and which can |
||||
reasonably be considered independent and separate works |
||||
in themselves, |
||||
i. are distributed subject to one of the FLOSS licenses |
||||
listed below, and |
||||
ii. the object code or executable form of those sections |
||||
are accompanied by the complete corresponding |
||||
machine-readable source code for those sections on |
||||
the same medium and under the same FLOSS license as |
||||
the corresponding object code or executable forms of |
||||
those sections, and |
||||
c. any works which are aggregated with the Program or with a |
||||
Derivative Work on a volume of a storage or distribution |
||||
medium in accordance with the GPL, can reasonably be |
||||
considered independent and separate works in themselves |
||||
which are not derivatives of either the Program, a |
||||
Derivative Work or a FLOSS Work. |
||||
If the above conditions are not met, then the Program may only |
||||
be copied, modified, distributed or used under the terms and |
||||
conditions of the GPL or another valid licensing option from |
||||
MySQL AB. |

Microsoft ResX Schema |
||||
|
||||
Version 2.0 |
||||
|
||||
The primary goals of this format is to allow a simple XML format |
||||
that is mostly human readable. The generation and parsing of the |
||||
various data types are done through the TypeConverter classes |
||||
associated with the data types. |
||||
|
||||
Example: |
||||
|
||||
... ado.net/XML headers & schema ... |
||||
<resheader name="resmimetype">text/microsoft-resx</resheader> |
||||
<resheader name="version">2.0</resheader> |
||||
<resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader> |
||||
<resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader> |
||||
<data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data> |
||||
<data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data> |
||||
<data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64"> |
||||
<value>[base64 mime encoded serialized .NET Framework object]</value> |
||||
</data> |
||||
<data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64"> |
||||
<value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value> |
||||
<comment>This is a comment</comment> |
||||
</data> |
||||
|
||||
There are any number of "resheader" rows that contain simple |
||||
name/value pairs. |
||||
|
||||
Each data row contains a name, and value. The row also contains a |
||||
type or mimetype. Type corresponds to a .NET class that support |
||||
text/value conversion through the TypeConverter architecture. |
||||
Classes that don't support this are serialized and stored with the |
||||
mimetype set. |
||||
|
||||
The mimetype is used for serialized objects, and tells the |
||||
ResXResourceReader how to depersist the object. This is currently not |
||||
extensible. For a given mimetype the value must be set accordingly: |
||||
|
||||
Note - application/x-microsoft.net.object.binary.base64 is the format |
||||
that the ResXResourceWriter will generate, however the reader can |
||||
read any of the formats listed below. |
||||
|
||||
mimetype: application/x-microsoft.net.object.binary.base64 |
||||
value : The object must be serialized with |
||||
: System.Runtime.Serialization.Formatters.Binary.BinaryFormatter |
||||
: and then encoded with base64 encoding. |
||||
|
||||
mimetype: application/x-microsoft.net.object.soap.base64 |
||||
value : The object must be serialized with |
||||
: System.Runtime.Serialization.Formatters.Soap.SoapFormatter |
||||
: and then encoded with base64 encoding. |
||||
|
||||
mimetype: application/x-microsoft.net.object.bytearray.base64 |
||||
value : The object must be serialized into a byte array |
||||
: using a System.ComponentModel.TypeConverter |
||||
: and then encoded with base64 encoding. |

<summary>Represents a SQL statement to execute against a MySQL database. This class cannot be inherited.</summary> |

<remarks> |

<B>MySqlCommand</B> features the following methods for executing commands at a MySQL database: |

<description>Retrieves a single value (for example, an aggregate value) from a database.</description> |

</item> |
||||
</list> |
||||
|
||||
You can reset the <B>CommandText</B> property and reuse the <B>MySqlCommand</B> |
||||
object. However, you must close the <A |
||||
href="MySql.Data.MySqlClient.MySqlDataReader.html">MySqlDataReader</A> |
||||
before you can execute a new or previous command. |
||||
|
||||
If a <A href="MySql.Data.MySqlClient.MySqlException.html">MySqlException</A> is |
||||
generated by the method executing a <B>MySqlCommand</B>, the <A |
||||
href="MySql.Data.MySqlClient.MySqlConnection.html">MySqlConnection</A> |
||||
remains open. It is the responsibility of the programmer to close the connection. |
||||
|
||||
<note> |
||||
Using the '@' symbol for paramters is now the preferred approach although the old pattern of using |
||||
'?' is still supported. Please be aware though that using '@' can cause conflicts when user variables |
||||
are also used. To help with this situation please see the documentation on the 'allow user variables' |
||||
connection string option. The 'old syntax' connection string option has now been deprecated. |
||||
</note> |

The following example creates a <A href="frlrfsystemdatasqlclientsqlcommandclasstopic.htm">MySqlCommand</A> and |

a <B>MySqlConnection</B>. The <B>MySqlConnection</B> is opened and set as the <A |
||||
href="frlrfsystemdatasqlclientsqlcommandclassconnectiontopic.htm">Connection</A> |

for the <B>MySqlCommand</B>. The example then calls <A |
||||
href="frlrfsystemdatasqlclientsqlcommandclassexecutenonquerytopic.htm">ExecuteNonQuery</A>, |
||||
and closes the connection. To accomplish this, the <B>ExecuteNonQuery</B> is |
||||
passed a connection string and a query string that is a SQL INSERT |

statement. |

||||
to the same <see cref="MySqlConnection"/> as the <see cref="MySqlCommand"/> object, |
||||
an exception will be thrown the next time you attempt to execute a statement. |
