Please check that you copy corelab.mysql.dll to your mobile device with your application. Test this problem on the emulator. If you cannot connect to MySQL database, try to set host IP address instead of name of the server.

thank you for your reply
I did. I copied dll file to both windows and app dir but It still run nothing.
I test it on the emulator, It's perfect.
I don't think it's connect to MySQL database
because I only put both line as following in my program (this)

Imports CoreLab <---- 1
......
+Windows form
Dim conn As CoreLab.MySql.MySqlConnection <---- 2

First line is ok
when I type second line in my program, It's working nothing.
I don't thing, It's connecting already.

Please help me. thanks a lot.

In your code row 2 .NET Framework tries to load corelab.mysql.dll assembly. Check once more that you correctly deploy your application with corelab.mysql.dll.

"I test it on the emulator, It's perfect. "
enclosed parts of code for your reference.
(I remark some code for my testing)
