API problems

Just getting learning about API calls- any idea how to fix the problems in this code? I am trying the count the number of files in a directory....
#include <windows.h>

int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow)
{
LPWIN32_FIND_DATA Found;
HANDLE hFile;
BOOL Retval;
int fileCount = 0;
const unsigned char path [] = {"C:\\Documents and Settings\\Administrator\\My Documents\\*.*"};

hFile = FindFirstFile(path, Found);

//Check for an NVALID_HANDLE_VALUE
if (hFile == 0)
MessageBox (NULL, TEXT ("Error File Non Existent"), TEXT ("HelloMsg"), 0) ;

do{
//increment the count of files present
if(Found->dwFileAttributes == 16 || Found->dwFileAttributes == 32)
fileCount ++;

Retval = FindNextFile(hFile, Found);
}while (Retval != 0);

FindClose (hFile);

//Don't think I can do this can I?
MessageBox (NULL, TEXT ("Files Present In Directory" && fileCount), TEXT ("HelloMsg"), 0) ;

return (0);
}

Do you get 15 errors like me? :)

Use WIN32_FIND_DATA and &Found :)

LPWIN32_FIND_DATA is merely a pointer. You should never use the LP* types because they just confuse.

As I said, Borland C++ compiler sucks:D

It is a 16-bit compiler.

If it's 16-bit then ***** it and get a REAL compiler :p

Good luck trying to use windows with it :D

I like the IDE though. :(

ok I think I understand what you mean, but by switching that O have a problem with the FindNextFile call (incompatible types):

altered code:

#include <windows.h>

int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow)
{
WIN32_FIND_DATA Found;
HANDLE hFile;
BOOL Retval;
int fileCount = 0;
const unsigned char path [] = {"C:\\Documents and Settings\\Administrator\\My Documents\\*.*"};

hFile = FindFirstFile(path, &Found);

//Check for an NVALID_HANDLE_VALUE
if (hFile == 0)
MessageBox (NULL, TEXT ("Error File Non Existent"), TEXT ("HelloMsg"), 0) ;

do{
//increment the count of files present
if(Found.dwFileAttributes == 16 || Found.dwFileAttributes == 32)
fileCount ++;

Retval = FindNextFile(hFile, Found);

}while (Retval != 0);

FindClose (hFile);

//Don't think I can do this can I?
MessageBox (NULL, TEXT ("Files Present In Directory"), TEXT ("HelloMsg"), 0) ;

return (0);
}

It always wants a pointer:

Retval = FindNextFile(hFile, Found);

...changes to...

Retval = FindNextFile(hFile, &Found);

I have you a link to the 32 bit version a longgg time ago:p

But I like the IDE. I can get the BC++ compiler free, but I am stuck with the built-in compiler for the TC++4.52 IDE. :(

humm.. now I am getting an error: unresolved exernal symbol _main

alternation:
#include <windows.h>

int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow)
{
WIN32_FIND_DATA Found;
HANDLE hFile;
BOOL Retval;
int fileCount = 0;
char path [] = {"C:\\Documents and Settings\\Administrator\\My Documents\\*.*"};

hFile = FindFirstFile(path, &Found);

//Check for an NVALID_HANDLE_VALUE
if (hFile == 0)
MessageBox (NULL, TEXT ("Error File Non Existent"), TEXT ("HelloMsg"), 0) ;

do{
//increment the count of files present
if(Found.dwFileAttributes == 16 || Found.dwFileAttributes == 32)
fileCount ++;

Retval = FindNextFile(hFile, &Found);
}while (Retval != 0);

FindClose (hFile);

MessageBox (NULL, TEXT ("Files Present In Directory"), TEXT ("HelloMsg"), 0) ;

return (0);
}

That's linker settings, not code errors. You need to make sure you selected the correct project type (Win32 Application or similar).

ooops, yup that was it, thanks!
