Help with GetOpenFileName

Hi,

Im trying to make a simple script whereby a user browses for a file, then this location can then be used in a variable. Can anyone tell me how this code can be used, and if it is C and not C# or C++.

Ive found several examples on the internet, but if I try to compile these examples I get lots of error codes saying it isnt correctly coded.

EDIT: For reference this is the code that I found that didnt compile:


#include <windows.h>

#include <fstream>

#include <stdafx.h>


int main()

{

printf("declaring...\n");

// Declare

OPENFILENAME ofn;       // common dialog box structure

char szFile[260];       // buffer for file name

HWND hwnd;              // owner window

HANDLE hf;              // file handle


printf("initialising...\n");

// Initialize OPENFILENAME

ZeroMemory(&ofn, sizeof(ofn));

ofn.lStructSize = sizeof(ofn);

ofn.hwndOwner = hwnd;

ofn.lpstrFile = szFile;

//

// Set lpstrFile[0] to '\0' so that GetOpenFileName does not 

// use the contents of szFile to initialize itself.

//

printf("setting...\n");

ofn.lpstrFile[0] = '\0';

ofn.nMaxFile = sizeof(szFile);

ofn.lpstrFilter = "All\0*.*\0Text\0*.TXT\0";

ofn.nFilterIndex = 1;

ofn.lpstrFileTitle = NULL;

ofn.nMaxFileTitle = 0;

ofn.lpstrInitialDir = NULL;

ofn.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST;


printf("displaying...\n");

// Display the Open dialog box. 

if (GetOpenFileName(&ofn)==TRUE) 

    hf = CreateFile(ofn.lpstrFile, GENERIC_READ,

        0, (LPSECURITY_ATTRIBUTES) NULL,

        OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL,

        (HANDLE) NULL);


printf("\n");

printf("opened. exiting...\n");

printf("...");


return 0;
