I am trying to get the ID of threads running in my program for debug
purposes. Is the following code correct:

DWORD dwID = GetCurrentThreadId();
CString sTemp;
sTemp.Format(_T("%d"),dwID);
TRACE(_T("%s Thread WHILE OK **\n"),sTemp);

I am getting thread IDs for example:
-1564372882

This number does not seem correct.

Is this right, if not, how should it be done?


Thanks

Harry

Well, you probably want to use a signed type, like 0x%08x instead of
%d since DWORD is unsigned.

Why not?

1. Why does it look bad to you?
2. You can use the Toolhelp API to get all thread IDs
3. You can use Remote Process Viewer to verify the IDs you get
programmatically.

It's an absolutely valid value for thread id. DWORD is unsigned value,
but you're using %d specifier in format string, which stands for
signed values - this why your value is interpreted as signed and you
see the negative number in your output.

I'd recommend you to use hex values, when printing id's and similar
stuff. Use %x format specifier for this:
sTemp.Format(_T("%x"),dwID);
