Remarks
Contains the name of the application’s executable file without an extension. Unlike m_pszAppName, this name cannot contain blanks. m_pszExeName is a public variable of type const char*.
Note If you assign a value to m_pszExeName, 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:
//First free the string allocated by MFC at CWinApp startup.
//The string is allocated before InitInstance is called.
free((void*)m_pszExeName);
//Change the name of the .EXE file.
//The CWinApp destructor will free the memory.
m_pszExeName=_tcsdup(_T(“d:\\somedir\\myapp”));
