</appSettings>



please tell me whats the problem

thank you

Try something like this..
Dim cnn as Sqlconnection
cnn = New SqlConnection(ConfigurationSettings.AppSettings("cnnstr"))

You got two things to keep in mind for Sqlconnection
1.Declare...Dim cnn as Sqlconnection
2.Initilize it..cnn = New SqlConnection(ConfigurationSettings.AppSettings("cnnstr"))
