Winforms: Close your form during Load event:

On occasion you may find that you need to open a form and have that form then decide if it needs to remain open.

Closing a form through click of a button is normally not an issue. Its as simple as:

Me.Visible = False
or
Me.Close

The second method will clear and remove the form from memory. But this means that the form would already have to be visible. Doing this during Form Load will cause an ObjectDisposedException.

But you want your form to close BEFORE it even becomes visible to the user? There are 2 ways to do this.

If your form is a dialog:
VB: Me.DialogResult = DialogResult.Cancel
C#: this.DialogResult = DialogResult.Cancel;

Otherwise, place this code in the form load event:
VB: Me.BeginInvoke(New MethodInvoker(AddressOf Me.Close))
C#: this.BeginInvoke(new MethodInvoker(this.Close));
