+ <li>With the connection parameters, the assembly is loaded, the connection type is verified that

<p><b>Integration with Windows.Forms</b> has not been started, such as, data binding

access to a remote PostgreSQL DBMS, or you will have to install
- one locally. PostgreSQL was first ADO.NET provider created in Mono.
+ one locally. PostgreSQL was the first ADO.NET provider created in Mono.
<p>Why use PostgreSQL? Because it is free software, has a client
library that is easy to use, PostgreSQL is easy to install on
user "postgres".

</pre>
</ul>
* <p>Important notes from this file are:
<ul>
- <p><b>2.</b> - Install the latest <a href="http://www.neuro.gatech.edu/users/cwilson/cygutils/OBSOLETE/V1.1/cygipc/index.html">CygIPC</a> package.

</ul>
<p>In the path mcs/class/System.Data/Test
- there is a PostgreSQL test program named
+ there is a test for Mono.Data.PostgreSqlClient named
PostgreTest.cs. Thanks goes to Gonzalo for creating the original
PostgreSQL test.
-
- <p>To use it to test System.Data, you
- modify the file to your PostgreSQL database
- connection requirements:
-
- <p>
- <ul>
- <li><b>dbname</b> database, ie., test</li>
- <li><b>host</b> hostname of the PostgreSQL DBMS Server, ie., localhost</li>
- <li><b>user</b> username, ie., someuser</li>
- <li><b>password</b> password, ie., mypass1234</li>
- </ul>
-
- <p>The connection string is in OLE-DB connection string format. Internally,
- SqlConnection converts this to the PostgreSQL connection string format.
-
- <p>
-<pre>
- OLE-DB: "host=localhost;dbname=test;user=joe;password=smoe"
-PostgreSQL: "host=localhost dbname=test user=joe password=smoe"
-</pre>
-
- <p>
- Note that OLE-DB includes the semicolons while PostgreSQL's connection
- string does not.
<p>
To compile the PostgresTest.cs program, do:
to PgSqlConnection, then you need to run mcs like:
<pre>
- mono f:/cygwin/home/DanielMorgan/mono/install/bin/mcs.exe \
+ mono C:/cygwin/home/MyHome/mono/install/bin/mcs.exe \
PostgresTest.cs \
-r System.Data.dll \
-r Mono.Data.PostgreSqlClient.dll
To run using mono, do:
<pre>
mono PostgresTest.exe
-</pre>
-
- <p>Below, I show how the output from PostgresTest. I have omitted a lot
- of the meta data for the columns except two columns. The classes
- used were from Mono.Data.PostgreSqlClient and were used to connect to a
- PostgreSQL database and retrieve data.

+ <li>With the connection parameters, the assembly is loaded, the connection type is verified that

+** GTK# On Linux
+<p>Where to get distributions of GTK# for Linux: TODO
+
+<p>Buidling on Linux:
+
+<ul>
+ <li>Get GTK# source from <a href="http://gtk-sharp.sourceforge.net">Gtk# Project</a>.</li>
+ <li>run ./autogen.sh --prefix=my_mono_installation_prefix</li>
+ <li>make</li>
+ <li>make install</li>
+</ul>
+
+** GTK# On Windows
+
+<p>There is a Windows Installer for GTK# <a href="http://www.sport-huettn.de/mono/gtk-sharp-0.6-stable-2.exe">here</a>.\r
+
+<p>If you want to build GTK# yourself on Windows:\r
+\r
+<p>To build gtk# under windows, you will need the following:\r
+\r
+<ul>\r
+ <li>cygwin from <a href="http://www.cygwin.com/">here</a> When installing Cygwin via setup.exe, \r
+ by default binutils and other tools do not get installed; you have to make \r
+ sure to select these items. Just make\r
+ sure Base and Development are set to Install.</li>\r
+ <li>Mono 0.17 or later from <a href="http://www.go-mono.com/download.html">here</a>\r
+ You can use Windows Setup Wizard (NT/2000/XP).</li>\r
+ <li>GTK+ 2.0 (and dependencies). You can obtain gtk+ 2.0 by either of the\r
+following:\r
+ <ul>\r
+ <li>You can get a Windows Installer at:\r
+ <a href="http://www.dropline.net/jade/download.html">here</a> </li>\r
+ <li>or get the separate binary and dev/lib packages at\r
+ at <a href="http://www.gimp.org/~tml/gimp/win32/downloads.html">here</a> </li>\r
+ <li>or binary package from Dev-C++ site <a href="http://www.bloodshed.net/dev/packages/gtk.html">here</a> </li>\r
+ <li>or get Gtk4Win <a href="http://wingtk.sourceforge.net/index.html">here</a> </li>\r
+ <li>or the source at <a href="http://www.gtk.org/">here</a> </li>\r
+ </ul>\r
+ </li>\r
+ <li>binary distriubtion of a current web browser\r
+ like Internet Explorer 4.0, Mozilla 1.0, or Netscape 7.0 which\r
+ includes things like msvcrt.dll.</li>\r
+ <li>Microsoft .NET Framework at\r
+ <a href="http://msdn.microsoft.com/downloads/default.asp?url=/downloads/sample.asp?url=/msdn-files/027/000/976/msdncompositedoc.xml&frame=true">here</a> </li>\r
+\r
+<p>If you are running Windows 95/98/ME, then you will need Unicode support.\r
+Look in\r
+mono-list archives for information about how to get\r
+Mono to work on Windows 9x.\r
+<a href="http://lists.ximian.com/archives/public/mono-list/2002-December/004158.html">here</a>\r
+\r
+<p>Environment Variables to set:\r
+<ul>\r
+<li>PATH - set to your mono installation bin and lib path.\r
+ For example, my mono installation prefix is:\r
+<pre>\r
+F:/cygwin/home/DanielMorgan/mono/install\r
+</pre>\r
+ <p>So, I would set my PATH in the Windows Control Panel as:\r
+<pre>\r
+F:/cygwin/home/DanielMorgan/mono/install/bin;F:/cygwin/home/DanielMorgan/mono/install/lib</li>\r
+</pre>\r
+</li>\r
+<li>LD_LIBRARY_PATH - set to your mono installation lib path</li>\r
+<li>PKG_CONFIG_PATH - set to your mono installation lib/pkgconfig path, such\r
+ as,\r
+<pre>\r
+ F:/cygwin/home/DanielMorgan/mono/install/lib/pkgconfig</li>\r
+</pre>\r
+\r
+ <p>If you got the gtk-sharp source, cd to the gtk-sharp directory, type:\r
+<pre>\r
+ ./autogen.sh --prefix=~/mono/install\r
+</pre>\r
+\r
+ <p>Set your --prefix= to whatever your mono installation prefix is located.\r
+ This will take awhile to go through the ./autogen.sh and ./configure...\r
+\r
+ <p>After that it finishes succesfully, you run make with the makefile.win32\r
+ like:\r
+<pre>\r
+ make -f makefile.win32\r
+</pre>\r
+\r
+ <p>After that finishes succesfully, you can copy to your mono installation lib\r
+ path like:\r
+<pre>\r
+ cp */*.dll ~/mono/install/lib\r
+</pre>\r
+</ul>\r
+\r
+<p>The pkg-config files for\r
+gtk+ 2.0 and dependencies will need to be set correctly if they haven't\r
+already been.\r
+\r
+<p>Look in your mono installation/lib/pkgconfig, such as,\r
+<pre>\r
+F:/cygwin/home/DanielMorgan/mono/install/lib/pkgconfig\r
+</pre>\r
+\r
+<p>You will find files like: gtk+-2.0.pc\r
+\r
+<p>Edit the line that says\r
+\r
+<pre>\r
+ prefix=something\r
+</pre>\r
+\r
+<p>And set it to your mono installation prefix, such as,\r
+\r
+<pre>\r
+ prefix=F:/cygwin/home/DanielMorgan/mono/install\r
+</pre>\r
+\r
+<p>Do this for all the .pc files in that directory. If there are not any, then\r
+you will need to create them. Or get them from somewhere like the dev\r
+packages at\r
+<a href="http://www.gimp.org/~tml/gimp/win32/downloads.html">here</a>\r

PostgreTest.cs. Thanks goes to Gonzalo for creating the original
PostgreSQL test.
-
- <p>To use it to test System.Data, you
- modify the file to your PostgreSQL database
- connection requirements:
-
- <p>
- <ul>
- <li><b>dbname</b> database, ie., test</li>
- <li><b>host</b> hostname of the PostgreSQL DBMS Server, ie., localhost</li>
- <li><b>user</b> username, ie., someuser</li>
- <li><b>password</b> password, ie., mypass1234</li>

-
- <p>The connection string is in OLE-DB connection string format. Internally,
- SqlConnection converts this to the PostgreSQL connection string format.
-
- <p>
-<pre>
- OLE-DB: "host=localhost;dbname=test;user=joe;password=smoe"
-PostgreSQL: "host=localhost dbname=test user=joe password=smoe"
-</pre>
-
- <p>
- Note that OLE-DB includes the semicolons while PostgreSQL's connection
- string does not.
<p>
To compile the PostgresTest.cs program, do:
to PgSqlConnection, then you need to run mcs like:
