TAB-funktion virker ikke MDI
Hej alle eksperter på Eksperten,Jeg er igang med at skrive et program og er stødt på et problem. TAB-funktionen virker ikke i programmet. Jeg får ingen errors ved compiling og kørsel. Tanken er at jeg godt vil kunne skifte mellem forskellige edit bokse med TAB-funktionen.
Jeg har prøvet at indsætte følgende kode i mit messageloop. Jeg skriver programmet i win32.
I Winmain API:
while(GetMessage(&Msg, NULL, 0, 0) > 0) { /* If no error is received... */
if(!IsDialogMessage(hwnd,&Msg))
{
TranslateMessage(&Msg); /* Translate key codes to chars if present */
DispatchMessage(&Msg); /* Send it to WndProc */
}
}
return Msg.wParam;
Når jeg indsætter ovenstående kode og trykker på TAB fjernes fokus fra editboxen, men ender ingen andre steder.
Når jeg ikke indsætter ovenstående kode og trykker på TAB, får jeg bare den klassiske window "ding" lyd.
Herunder er indsat det umiddelbare relevante for mit program:
I main.cpp:
#include <windows.h>
#include <commctrl.h>
#include <stdlib.h>
#include <Windowsx.h>
#include <iomanip>
#include <fstream>
#include <algorithm>
#include <locale.h>
#include <sstream>
#include <Richedit.h>
#include <CommDlg.h>
