[WinApi C++] Błąd z pamięcią podczas zamykania okna potomnego » 2015-03-06 17:06:18 Witam. Stworzyłem okno potomne z polami tekstowymi i przyciskiem. Chcę aby po naciśnięciu przycisku okno się wyłączało i dane z pól tekst. zapisywało do zmiennych. Zapisywanie działa dopóki jest wypełnione co najmniej jedno pole. Gdy nie wypełnię nic tylko od razu zapisuję pojawia się błąd: App.exe has triggered a breakpoint. while( GetMessage( & msg1, NULL, 0, 0 ) )
{
TranslateMessage( & msg1 );
DispatchMessage( & msg1 );
}
EnableWindow( window_main, TRUE );
return msg1.wParam;
Jak można to naprawić aby po zostawieniu pustych pól nie wywalało tego błędu? LRESULT CALLBACK WndProc( HWND window_main, UINT msg, WPARAM wParam, LPARAM lParam )
{
switch( msg )
{
case WM_CLOSE:
DestroyWindow( window_main );
if( new_Window != NULL ) DestroyWindow( new_Window );
break;

PostQuitMessage( 0 );
break;
