Application Security Testing: An Integral Part of DevOps


This is a small utility funtion will simply put up a userdefined message box with a string formatted like printf().

Example:


int MsgBox(UINT nType, PSTR sz,...)
{ 
    char ach[512];
    va_list args; 
    va_start(args, sz); 
    wvsprintf (ach, sz, args); /* Format the string */
    int retval = AfxMessageBox (ach, nType == 0 ? MB_OK|MB_ICONEXCLAMATION : nType);
    
    return retval;
}


void main(int argc, char *argv[])
{
  MsgBox(MB_OK|MB_ICONINFORMATION, "There are %ld commandline parameters - parameter one is %s", argc, argv[1]);
}

  • You forgot to call va_end()

    Once you are done, you have to call va_end()
    Just add 
    va_end( args );
    after the call to wvsprintf()
