Die Implementierung
void CFiletestDlg::OnButton3()
{

Ein Filedialog:
void CFiletestDlg::OnButton4()
{
// TODO: Code für die Behandlungsroutine der Steuerelement-Benachrichtigung hier einfügen
UpdateData(TRUE);
//CString strFilter = _T("All Files (*.*) |*.*| |");
CString strFilter = _T("INI (*.INI) |*.INI| |");
CFileDialog dlg(TRUE, NULL, m_files, OFN_HIDEREADONLY|OFN_EXPLORER, strFilter, NULL);
dlg.m_ofn.lpstrTitle = _T("File auswählen");
if (dlg.DoModal() == IDOK)
{
m_dir = dlg.GetPathName();
UpdateData(FALSE);
//m_combo2.SetEditSel(dlg.GetPathName().GetLength(), dlg.GetPathName().GetLength());
}
}
In der Implementierung mußt Du dir noch das für Dich benötigte raussuchen sonst ist die Klasse funktionierend (x.h;x.cpp).
Ist von einem meiner Programme.
