how to compare a CString?

the following does not seem to work.

CString id = PictureEntries[i].attribute("id").value();

if (id.Compare("2222") == 1){
cout << id << endl;
}

Try a windows group, CString isn't standard C++.

Whats a CString?

As a hint: what is the difference between a null terminated sequence
of characters and one that isn't null terminated? The point here is
that if you don't know or aren't sure, use a little brain power:

CString id("abcdef")
if( id.Compare( CString("abcdef") )
{
// do stuff
}

Which is why you shouldn't ask CString questions here! The above is
wrong.

if (0 == id.Compare("abcdef"))
{
// do stuff
}

or

if (id == "abcdef")
{
}

The OP also asked in an MS group and "learned" how to make the proper
call. Though the term RTFM was missing in those posts.
