How to block double click in overridden WndProc function in Windows Forms?

Question

I have a form created in Windows Forms which is draggable wherever I click. I made it by overriding WndProc function which in turn modifies each click as it was a title bar

Answer 1

I was having the same problem today in C++. I used JaredPar's solution but with WM_NCLBUTTONDBLCLK (0x00A3) instead of WM_LBUTTONDBLCLK, that did the trick for me! It's working because the double click message is being sent from a non-client (NC) area, which is the "virtual" title bar (HTCAPTION) in this case.
