In our daily work, we sometimes need a window or diaog which have a fixed size. now I give the way to fullfill this target. if you project is based on SDI or MDI, that is to say you want fix you window size.

You can refer to following code:

Bool cmainframe: precreatewindow (createstruct & CS)

{If (! Cframewnd: precreatewindow (CS ))

Return false;

CS. Style & = ~ (Ws_thickframe); // Note: Remove this style. Return

Cframewnd: precreatewindow (CS );

}

Modifystyle (wm_thickframe, wm_dlgframe, 0 );
