For some reason, the child window of the main window won't resize, when the main window is resized.
Code:
Child window creation:
[source]
HWND hWndLeftToolbar = CreateWindowEx( 0, "button", NULL,WS_CHILD,
0, 0, 150, 600,
hWndMain, NULL, hInstanceMain, NULL);


Button_Enable(hWndLeftToolbar,FALSE);

//MoveWindow(hWndLeftToolbar,0,0,300,200,TRUE);

ShowWindow(hWndLeftToolbar,TRUE);
[/source]
MainWindproc WM_SIZE message handling
[source]case WM_SIZE:
if( hWndLeftToolbar )
{
MoveWindow(hWndLeftToolbar,0,0,300,200,TRUE); // just for debugging.
ShowWindow(hWndLeftToolbar,SW_SHOW);
}


InvalidateRect(hWndMain,&(MainWindow.WindowRect),GL_TRUE);
return 0;[/source]
If I change the size (MoveWindow) just after creating the child window, it resizes just fine.

Thanks for any help in advance!

Got it working with [font="Courier New"]EnumChildWindows,[/font] but it's pretty strange I can't simply use [font="Courier New"]MoveWindow[/font]
