Question

I’m trying to use this example
to create a program which will list all filenames in a directory in a Windows::Forms::ListBox.

Since the user won’t be doing any inputting I won’t be needing the
void DisplayErrorBox(LPTSTR lpszFunction) function along with other error checking.

When I click the button that triggers the event this is what is shown in the list box.

o //&#o/
/ //
/ //
/ //
/ //
/ //
/ //
/ //

Also, only one row appear each time i click the button.
It’s supposed to find all the files in the directory and list them not just find the next file each time I click the button.

I also want to use a relative strPath, not absolute…
So far this is what I’ve done with the code:

private:
    void List_Files()
    {
        std::string strPath =   "C:\\Users\\Andre\\Dropbox\\Programmering privat\\Diablo III DPS Calculator\\Debug\\SavedProfiles";     
        TCHAR* Path = (TCHAR*)strPath.c_str();

        WIN32_FIND_DATA ffd;
        LARGE_INTEGER filesize;
        TCHAR szDir[MAX_PATH];
        size_t length_of_arg;
        HANDLE hFind = INVALID_HANDLE_VALUE;

        // Prepare string for use with FindFile functions.  First, copy the
        // string to a buffer, then append '\*' to the directory name.

        StringCchCopy(szDir, MAX_PATH, Path);
        StringCchCat(szDir, MAX_PATH, TEXT("\\*"));

        // List all the files in the directory with some info about them.

        do
        {
          if (ffd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
          {
              //If it's a directory nothing should happen. Just continue with the next file.

          }
          else
          {
                //convert from wide char to narrow char array
                char ch[260];
                char DefChar = ' ';

                WideCharToMultiByte(CP_ACP,0,(ffd.cFileName),-1, ch,260,&DefChar, NULL);

                //A std:string  using the char* constructor.
                std::string str(ch);
                String ^ sysStr = gcnew String(str.c_str());

              MessageBox::Show("File Found", "NOTE");
              ListBoxSavedFiles->Items->Add (sysStr);

          }
        }
        while (FindNextFile(hFind, &ffd) != 0);

        FindClose(hFind);
    }

Answer 1

FindFirstFile() is never called, you need to call it before calling FindNextFile():

HANDLE hFind = FindFirstFile(TEXT("C:\\Users\\Andre\\Dropbox\\Programmering privat\\Diablo III DPS Calculator\\Debug\\SavedProfiles\\*"), &ffd);

if (INVALID_HANDLE_VALUE != hFind)
{
    do
    {
        //...

    } while(FindNextFile(hFind, &ffd) != 0);
    FindClose(hFind);
}
else
{
    // Report failure.
}
