OK, first remove the _T() around the name of the variable, because that is nonsense.
Next, tell us the EXACT string that was used. Since you say it has a time, is the time
something like 00:00:00? Note that colons would be illegal in a filename, which would
lead to the error you saw about invalid syntax.
Since you didn't bother to tell us the EXACT sequence of characters that constituted the
filename, there is no way to guess what went wrong. It is essential when reporting
problems like this that you give us ALL the information we need to analyze it, not some
meaningless error.
The only correct thing you could have done here is
if(hFile == INVALID_HANDLE_VALUE)
{
DWORD err = ::GetLastError();
CString s;
s.Format(_T("Couldn't create file\n\"%s\"\nError code %d"),
fileName, err);
AfxMessageBox(s);
}
Note that the VERY FIRST THING you do is ::GetLastError(), you must NEVER defer it to some
later point in your code. Next, you must ALWAYS display the EXACT STRING you use. I
would decode the error code using ::GetLastError(), but unless you display (and tell us)
the EXACT INFORMATION INVOLVED, there is no way to tell what is going wrong!

This is the code to create the file ..
fileName is variable.
it consists of current date, time and a number,
HANDLE hFile = CreateFile(_T(fileName),
GENERIC_WRITE, FILE_SHARE_READ,
NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
if (hFile == INVALID_HANDLE_VALUE)
{
TRACE("\n Couldn't create the file (%d)",GetLastError());
AfxMessageBox(_T("Couldn't create the file!"));
}
Trace prints out 123.
