Open Dialog

[Behemoth]

Hey everyone,

I don't really care whether there's an example of this in either VC or VB, but I'm not sure how to a an Open File Dialog where users should only be able to open or select directories. Although the VB dialog interface is very simple...it doesn't look like there's a simple way to filter out all files except directories and allow users to both do directory crawls and select directories.

Not sure if this helps but check out the constructor for CFileDialog.

An aternative is to use SHBrowseForFolder. The following is not exactly what you would need, but it is probably close.


void CDialogsDlg::OnSysFldrs() {
LPITEMIDLIST pidlBrowse=NULL;
CString SystemFolder;
LPMALLOC g_pMalloc;
BROWSEINFO bi;
if (!SUCCEEDED(SHGetMalloc(&g_pMalloc))) {
MessageBox("Internal error: Malloc failure", AfxGetAppName());
return;
}
if (!SUCCEEDED(SHGetSpecialFolderLocation(m_hWnd, CSIDL_DESKTOP, &pidlBrowse))) // CSIDL_NETWORK
MessageBox("Internal error: special folder not found", AfxGetAppName());
else {
bi.hwndOwner = m_hWnd;
bi.pidlRoot = pidlBrowse;
bi.pszDisplayName = SystemFolder.GetBuffer(MAX_PATH);
bi.lpszTitle = "Sample System Folders Dialog";
bi.ulFlags = 0; // BIF_BROWSEFORCOMPUTER;
bi.lpfn = NULL;
bi.lParam = 0;
pidlBrowse = SHBrowseForFolder(&bi);
SystemFolder.ReleaseBuffer(-1);
MessageBox(SystemFolder, AfxGetAppName());
}
if (pidlBrowse != NULL)
g_pMalloc->Free(pidlBrowse);
}
