Trying to make a form's background transparent, without it losing its ability to receive clicks.
this.Opacity makes the whole form transparent (not just the background
BackColor = Color.Red; TransparencyKey = BackColor;
makes the background of the form transparent and click through-able. I want the form to be transparent , but it should be able to receive clicks
Someone suggest overwriting WndProc to change HTCAPTION . BUt after trying that, the form is still click through-able
Also this form is also the 'base' form.
