C++: How to handle minimize and maximize

Question

0.00/5 (No votes)

See more:

I have changed my window style using the following function

C++

SetWindowLong(g_hDialogWindow, GWL_STYLE,GetWindowLong(g_hDialogWindow, GWL_STYLE) & (~(WS_CAPTION | WS_BORDER)));

Setting position of main dialog

C++

SetWindowPos(g_hDialogWindow,HWND_TOP,0,0,GetSystemMetrics(SM_CXSCREEN),GetSystemMetrics(SM_CYSCREEN), SWP_SHOWWINDOW);

Now suppose I minimize my application using the (window+m) key then again maximize my application. After that I want to add some repaint function.

Which message should i handle? I have tried using wm_paint but its not working properly.

--Thanks for the help.

Solution 2

You should handle WM_QUERYOPEN message.
Read here carefully:
