how to show dialog in login form?

[rajesh.forum]

i need to close the login form and to navigate another form when userid and password gets matched..

Set the main form as startup form. In Application Startup event you show the login form as dialog and use e.Cancel to stop application from starting if login fails. There's a code example in post 4 of this thread: http://www.vbdotnetforums.com/showthread.php?t=19637

When you are finished with the login stuff set Me.DialogResult=OK if ok or another value if not ok.

John

Is that how you would handle the login if you were using the standard windows login form, or could you use the same code if you are creating your own login form?

I ask because I have a standard login form and class that I use for all my small apps that are password protected.

Thanks

Yes, the LoginForm template is designed as a dialog, you just has to set DialogResult as appropriate to the authentication.
