New to Windows programming - help!

I'm following a simple tutorial (the adrianxw.dk one) to list the files in a directory. The code is this:

Code:

#include <windows.h> 
#include <iostream> 
using namespace std;

int main()
{
    HANDLE hFind;
    WIN32_FIND_DATA FindData;

    cout << "A very basic FindFirst/Next demo.\n" << endl;

// Find the first file

    hFind = FindFirstFile("C:\\Windows\\*.exe", &FindData);
    cout << FindData.cFileName << endl;

// Look for more

    while (FindNextFile(hFind, &FindData))
    {
        cout << FindData.cFileName << endl;
    }

// Close the file handle

    FindClose(hFind);

    return 0;
}

However when I try to compile it using Visual C++ Express, I'm given the following error:

Code:

 error C2664: 'FindFirstFileW' : cannot convert parameter 1 from 'const char [17]' to 'LPCWSTR'

Can someone please explain what's going wrong?

OK so I did the obvious and cast the string argument to a LPCWSTR and it compiles OK...except that when I run it, all it prints is a single address in hex, instead of file names. How can I get this to work?

LPCWSTR is a wide character string. Either you need to undefine unicode or else precede all string literals with 'L', eg:

FindFirstFile(L"C:\\Windows\\*.exe", &FindData);

Do you know how to disable unicode in VC++ Express? I did this a while ago but I can't seem to find the option again.

False alarm. I found and disabled unicode and the program is working....
