Hi, problem described in my previous note (Timeouts are not supported …) is already solved on mySQL side, here is the bug report http://bugs.mysql.com/50321 with the solution provided. It is part of 6.2.3 changelog.

Thanx guys, you helped me a lot. I did the same as JFS and it works.

But note, that if you try the same wit connector 6.2.2 then you will get the problem “Timeouts are not supported on this stream”. This is most likely bug of 6.2.* releases (up to 6.2.2 so far). When I downgraded to 6.1.3 connection was opened fine and I could read the data. I will keep you posted if there is a fix available with new release of .NET connector.

Thanks for the information, I’ve downloaded de latest version of the Connector/Net, 6.1.3. The 1st error, that raises an IndexOutOfRangeException is fixed but the Resoruce file error keeps alive.
I fix it adding de Mysql.Data.CF project to my solution, where i have the device application project.

After adding this project, i had to comment the last line of the AssemblyInfo,
[assembly: AssemblyKeyName("ConnectorNet")].
if you keep this line uncommented, the project not buids. :(

Doing this, i can connect to mysql server!

Zandro, i think you have a network problem, i’ve the same problem using de VS2005 emulator, until i read that it is necessary to conect it through Microsoft ActiveSync. If you don’t connect it, the emulator is not connected with de MySQLl server, because ther is no connection between both Operating systems (emulator and server)

I hope this help.

Hi Nicholas,
Great help. Thanks! Another favor… Your compiled file worked when I was using “Server=127.0.0.1″ , if I specify another location it gives me an error
“MySql.Data.MySqlXlient.MySqlException: Unable to connect to any of the specified hosts.”

Connection String is: conn = new MySql.Data.MySqlClient.MySqlConnection(“Server=192.168.1.102;Uid=genuser;Pwd=password;Database=utils;”);

I have added that ip as part of the host for genuser (which I believe should already be able to connect with any host). Any ideas on why I can only connect through “127.0.0.1″ and not using a different IP where my MySQL server is located at???

Also, I downloaded the source for the 6.1.3 mysql .net connector but I was unable to compile it. Kept getting a “The imported project “C:\Program Files\Visual Studio 2005 SDK\2007.02\VisualStudioIntegration\Tools\Build\Microsoft.VsSDK.targets” was not found” error. Kindly guide me on how compile the project.

Any help is appreciated. Thanks.

Hello Nicholas,

Thanks for the information. Would you mind sending me an email with the updated “MySql.Data.CF.dll” file? I downloaded the source files from MySQL website (http://dev.mysql.com/downloads/connector/net/6.0.html) but got many errors while trying to open the “MySQLClient.sln” on VS2008.

Thanks!
