Exception of type System.Stack

it gives me an error every time i close my app's.

im very new in this thing..pls. help me..:cry:

You should post some code that you suspect it errors out(in closing or under that button event handler) . First , if you didn't use any try-catch block , then you should try so you can get more descriptive error messages .

thanks pirate for the reply.
ok i got it.

why it gives me an error?

VB Code:

Private Sub DepartmentEntry_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing
        cn.Close()
        me.close()-----> this gives me an error.
error:[i]Exception of type System.StackOverflowException was thrown [/i]
    End Sub

Because Me.Close() fires the Closing event, which in turn calls Me.Close(), which fires the Closing event, and so on.

And there's the perfect example of a stack overflow.
