CWnd::SetRedraw(False) make mouse go throught window

So I have a MFC application which flick when we do some action. So I figured I would set SetRedraw(false) and set it to true at the end of the function.

The application doesn't refresh anymore but if I click on it while SetRedraw(false), my cursor is not catched by my application, it goes throught it and set focus on the application below.

Anyone has some kind of idea how I could fix that.

Solution

  • I ended up using CWnd::LockWindowUpdate instead after some research. It freezes the update but doesn't act if the window was transparent.
