Hi Rgain :
Your connection string is :
server=MSDESQL;database=CuteChatSample;UID=websqlquiry;PWD=abcde;App=CuteChat
Is the MSDESQL the name of your pc ? or it's just an instance of SqlServer on your pc?
If so , the connection string should be :
server=localhost\MSDESQL;database=CuteChatSample;UID=websqlquiry;PWD=abcde;App=CuteChat
and the provider 'Sample' should be :
<provider name="Sample" sqlDataProviderType="CuteChatSample.MySqlDataProvider,CuteChatSample" />
(The CuteChatSample.MySqlDataProvider is an buildin class for the sample , please see CuteChatSample/MySqlDataProvider.cs for more)
--------
You could run [START]-[Program]-[CuteChat]-[CuteChat Configuration] to help you create a new sample application too.
Hope this helps.
