V628. It is possible that a line was commented out improperly, thus altering the program's operation logic.

Jul 03 2012

The analyzer has detected a potential error: two 'if' operators in a row are divided by a commented out line. It's highly probable that a code fragment was commented carelessly. The programmer's carelessness has caused a significant change of the program execution logic.

Consider this sample:

if(!hwndTasEdit) 
//hwndTasEdit = getTask()
if(hwndTasEdit)
{
 ...
}

The program has become meaningless. The condition of the second 'if' operator never holds. This is the correct code:

//if(!hwndTasEdit) 
//hwndTasEdit = getTask()
if(hwndTasEdit)
{
 ...
}

The analyzer doesn't generate the warning for code where code formatting demonstrates deliberate use of two 'if' operators in a row divided by a comment line. Here is an example:

if (Mail == ready) 
  // comment
  if (findNewMail)
  {
   ...
  }
