Modify the WM_COMMAND Case

You need to process menu commands. In this application, instead of performing tasks, all menu commands activate a “Command not implemented” message box. Replace the WM_COMMAND case with the following statements:

case WM_COMMAND:

switch (wParam) {

case IDM_ABOUT:

lpProcAbout = MakeProcInstance(About, hInst);

DialogBox(hInst, “AboutBox”, hWnd, lpProcAbout);

FreeProcInstance(lpProcAbout);

break;

/* file menu commands */

case IDM_NEW:

case IDM_OPEN:

case IDM_SAVE:

case IDM_SAVEAS:

case IDM_PRINT:

MessageBox (

GetFocus(),

“Command not implemented”,

“EditMenu Sample Application”,

MB_ICONASTERISK | MB_OK);

break;

case IDM_EXIT:

DestroyWindow(hWnd);

break;

/* edit menu commands */

case IDM_UNDO:

case IDM_CUT:

case IDM_COPY:

case IDM_PASTE:

case IDM_CLEAR:

MessageBox (

GetFocus(),

“Command not implemented”,

“EditMenu Sample Application”,

MB_ICONASTERISK | MB_OK);

break;

}

break;
