More win32 help

king_of_inismac

ok guys,

I'm new to win32 programming,

Have isolated the problem.

I want to draw initially in my window, so I place the code in the main windowProc under the WM_PAINT and the code works fine.

Next a dialog box pops up and the user inputs some settings data, the data is acquired.

After it is acquired, I set a flag variable and from the dialog box's proc code, call sendMessage(hwnd,WM_PAINT, 0,0),

but this seems to call the WM_PAINT function within the dialog proc, rather than the WM_PAINT within the main windows PROC code.

My plan was to set the data_acquired flag, call WM_PAINT in the main window proc again, but this time draw the contents of the acquired data.

Has anyone any ideas (or preferably some code ;-) ) to help me out,
thanks,
king

You don't need to send the WM_PAINT message. use InvalidateRect to mark the main window as needing repainting and the system will send your window a WM_PAINT message.
