FindFirstFile trouble

Hi. I'm trying to access the file names of all the files in a folder. I am trying to use FindFirstFile to do this. However, I'm having some issues.

Code:

void TestFunction()
{	
	string directoryPath = "C:\\TestFolder\\";

	WIN32_FIND_DATA FindFileData;
	HANDLE hFind = INVALID_HANDLE_VALUE;

	hFind = FindFirstFile(directoryPath.c_str(), &FindFileData);	
	//cout << FindFileData.cFileName << endl;

	if(hFind != INVALID_HANDLE_VALUE)
	{
		cout << FindFileData.cFileName << endl;
		cout << "Test" << endl;
	}
	else
	{
		cout << "Fail" << endl;
	}
}

Currently, "Fail" will print. If I try to output the file name before the if statement, it prints jibberish. I've looked over a bunch of examples, but I can't seem to figure out what the problem is.
In this current example, I had to change my project settings to "Use Multi-Byte Character Set" instead of "Use Unicode character set". If I leave it as "Use Unicode character set", I change the following in my code:

Code:

hFind = FindFirstFile(LPCWSTR(directoryPath.c_str()), &FindFileData);

This will also print "Fail". If I output the file name before the if statement, it outputs: 0012FC18

Any ideas?

>>hFind = FindFirstFile(LPCWSTR(directoryPath.c_str()), &FindFileData);
This is wrong on so many levels. Don't do it. Setting project settings to multi-byte is correct.

As for the problem... try appended "*.*" to your string.
If it doesn't work, remember to get the error code by calling GetLastError to see what went wrong.

That fixed it. I guess I still had it set to the Unicode setting when I added the astrisk the first time.

Thanks for your help.

If you want all files in the folder, you need to do something like this...

Code:

void EnumFiles(TCHAR *Path)
  { WIN32_FIND_DATA  da;   // directory data
     HANDLE  ds;     // directory handle
     SetCurrentDirectory(Path);
     ds = FindFirstFile(_TEXT("*.*"),&da);
     do
       { // do what you need with the da record here

        } while( FindNextFile(ds,&da) != ERROR_NO_MORE_ITEMS);
     FindClose(ds);  }

There's an internal index that is reset to 0 each time you call FindFirstFile() and it's incremented each time you call FindNextFile() so unless you do it in a loop, you'll only get the first filename ( a dot ) each time.
