Is there a WM_ message which...

[Mark Jones]

Hi, is there a WM_? message which triggers only once, AFTER the window is drawn?

There is WM_ENTERIDLE, but this sounds like it would be called continuously. Is conditionals the only answer?

TIA. :)

Hi Mark,
I way to do what you want is to intercept (subclassing) the WM_PAINT. Once you have done it, execute the default drawing code (DefWndProc) and then your own code, returning the the value given by the default code.

What you need is WM_CREATE. As mentioned by MSDN here, this message is sent *after* the window is created, but *before* it is visible. This is when you normally create child windows. If you want control before the window is created, look for the WM_NCCREATE message.

There is no specific message which is sent only ONCE after a window has been painted. There are other messages you can use (WM_SHOWWINDOW, WM_ACTIVATE, etc) to process during limited conditions of the window. If you only want to process a message ONCE AFTER the window is VISIBLE, then the best method is to POST yourself a message to your windows/ctrl in the WM_CREATE handler.
