    如果标志=  2  >然后 e.Cancel =  1 
    结束
结束 子

谢谢你. :)

I''m trying to allow the user to choose whether or not they really want to close the form, in case they accidentally click the X button. I have it where the application asks whether they want to close it, and when they click "Yes", it closes. But, what should I put in the "No" event handler so that it stops the form from closing?

The code that I have so far is in the Form''s (Form_Closing) event.

解决方案

Try setting Cancel = True in the Closing event to prevent the form from unloading.

Hi! I have the solution of this Problem

Use This Code :

Private Sub FrmMDI_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
    Dim Flag As Integer
    Flag = (MsgBox("Are you sure you want to exit ? ", vbInformation + vbOKCancel, "Exit"))
    If Flag = 2 Then e.Cancel = 1
    End
End Sub

And Your Problem is Solved.
Thank you. :)
