Specifies the name of the application.
The application name can come from the parameter passed to the CWinApp constructor, or, if not specified, to the resource string with the ID of AFX_IDS_APP_TITLE. If the application name is not found in the resource, it comes from the program's .EXE filename.
Returned by the global function AfxGetAppName. m_pszAppName is a public variable of type const char*.
If you assign a value to m_pszAppName, it must be dynamically allocated on the heap. The CWinApp destructor calls free( ) with this pointer. You many want to use the _tcsdup( ) run-time library function to do the allocating. Also, free the memory associated with the current pointer before assigning a new value. For example:
CWnd* pWnd = AfxGetMainWnd(); // Set pWnd to some CWnd object whose window has already // been created. // The following call to CWnd::MessageBox uses the application // title as the message box caption. pWnd->MessageBox(_T("Some message"), AfxGetApp()->m_pszAppName); // A more direct way to get the application title is to // call AfxGetAppName: pWnd->MessageBox(_T("Some message"), AfxGetAppName()); // An easier way to display a message box using the application // title as the message box caption is to call AfxMessageBox: AfxMessageBox(_T("Some message"));
