[Dev-C++] Saving text from EDIT control

[Noorez K. <lor...@ho...>]

For my program, I need a part that is like a simple text editor, but I can't 
get the 'save' function to work. This error is received while debugging : 
'An Access Violation (Segmentation Fault) raised in your program'  at the 
marked line. I attached the entire program so that you can try to run it.

void SaveText(HWND main)
{
  int length;
  char* buffer;

  length = GetWindowTextLength(GetDlgItem(main, IDC_MAIN_EDIT));

  if(length>0)
  {
    OPENFILENAME saveFileInfo;

    saveFileInfo.lStructSize = sizeof(saveFileInfo);
    saveFileInfo.hwndOwner = main;
    saveFileInfo.hInstance = gThisInstance;
    saveFileInfo.lpstrFilter = ".TXT"+'\0';
    saveFileInfo.lpstrCustomFilter = '\0';
    saveFileInfo.nMaxCustFilter = 0;
    saveFileInfo.nFilterIndex = 1;
    saveFileInfo.lpstrFile = "Untitled.txt";
    saveFileInfo.nMaxFile = sizeof( saveFileInfo.lpstrFile );
    saveFileInfo.lpstrFileTitle = 0;
    saveFileInfo.lpstrInitialDir = "C:\\";
    saveFileInfo.lpstrTitle = "Hey";
    saveFileInfo.nFileOffset = 0;
    saveFileInfo.nFileExtension = 0;
    saveFileInfo.lCustData = 0;
    saveFileInfo.lpstrDefExt = 0;
    saveFileInfo.Flags = OFN_HIDEREADONLY;
    saveFileInfo.lpfnHook = (LPOFNHOOKPROC)0;
    saveFileInfo.lpTemplateName = 0;


    GetSaveFileName(&saveFileInfo)
    buffer = new char[length+1];
    GetDlgItemText(main, IDC_MAIN_EDIT, buffer, length + 1);
    ifstream saveTextFile("SaveText.txt", ios::binary);
    saveTextFile >> buffer;
    saveTextFile.close();
    delete buffer;

  }
}
