hi,
I'm trying to list all the .jpg files using CFileFind class in a console program.  I put 3 .jpg files in the same directory for testing.
The program returns 3 32-bit integer, which looks like the addresses of something, but not the names of the jpg files.  what's wrong with the code?
CFileFind finder;
		BOOL bWorking = finder.FindFile(_T("*.jpg"), 0);
		bWorking ==0? printf("not find \n"): printf("found \n");
		while (bWorking)
		{
			bWorking = finder.FindNextFile();
			cout<<(LPCTSTR)(finder.GetFileName()) << endl;
			printf("\n"); }

It seems that your porject settings are UNICODE, so you need to use 'wcout' instead, e.g.
CFileFind finder;
                BOOL bWorking = finder.FindFile(_T("*.jpg"), 0);
                bWorking ==0? printf("not find \n"): printf("found \n");
                while (bWorking)
                {
                        bWorking = finder.FindNextFile();
                        wcout<<(LPCTSTR)(finder.GetFileName()) << endl;  // <--- here
                        printf("\n"); }

the first .jpg file is displayed,  but an error window poped out immediately says
"Debug assertion Failed"  and I have to abort the program.
How to solve that?

What is the rest of your code in that function?

o, I put a finder.Close() in the loop which caused the problem.  Thanks.
