Showing Files

Is there a c++ function that allows you to show all the txt files in a folder? I'm using the Borland C++ Compiler V4.52.

You can use the WinAPI functions FindFirst, FindNext and FindClose

Here's a sample function I wrote:

Code:

---

bool outputDirectory(ostream &outputFile, const char *pcszPath)
{
        WIN32_FIND_DATA FindFileData;
        HANDLE hFind;

        hFind = FindFirstFile(pcszPath, &FindFileData);

        if (hFind == INVALID_HANDLE_VALUE)
        {
                return 1;
        } else {

                do {

                        outputFile << FindFileData.cFileName << endl;

                } while (FindNextFile(hFind, &FindFileData));
        }
        FindClose(hFind);
        return 0;
}

---

I suppose I should show how to use the function...

Code:

---

#include <windows.h>
#include <fstream.h>

bool outputDirectory(ostream &outputFile, const char *pcszPath)
{
        WIN32_FIND_DATA FindFileData;
        HANDLE hFind;

        hFind = FindFirstFile(pcszPath, &FindFileData);

        if (hFind == INVALID_HANDLE_VALUE)
        {
                return 1;
        } else {

                do {

                        outputFile << FindFileData.cFileName << endl;

                } while (FindNextFile(hFind, &FindFileData));
        }
        FindClose(hFind);
        return 0;
}

int main (int argc, char *argv[])
{
        ofstream fout("c:\\list.txt", ios::trunc);

        outputDirectory(fout, "c:\\*.txt");  // This will print out all files with the extension txt.
        cout << "Done" << endl;
        fout.close();
       
        return 0;
}
