Dear Avinash, Thanks for your code. But I think that I haven't explained my need correctly. It is like this ---- Users will go to login form(of course, it will be .exe). User will type MySQL login ID and password and computer name hosting MySQL.
Login ID & password will be different for each & every user. If the ID & password are correct, then permission is granted and Main Form opens. Otherwise permission is denied. Therefore, I can't hardcode connection string in app.config as you say. You code reads (in app.config) --- <connectionStrings> > <add name="DefaultConnectionStringToMasterDatabase" > connectionString="Data Source=ServerName;Initial Catalog=Master;integrated > security=True;uid=UserName;pwd=Password" > providerName="System.Data.SqlClient" /> > </connectionStrings> Here, we can't hardcode like "Data Source=Wheels;uid=Vineet;pwd=qwert $1" In this situation, what's your call? ---Vineet.
