[MFC] Select Directory dialog box and select File dialog box

In MFC programming often need to use the selection of directories and select the file interface, the following summarizes the two types of dialog boxes I commonly used to generate the method:

Select Directory dialog box

Select Directory button
void Cdcpackerdlg::onbnclickeddecgen ()
{
Char Szpath[max_path]; Store the selected directory path
CString str;

ZeroMemory (szpath, sizeof (szpath));

Browseinfo bi;
Bi.hwndowner = m_hwnd;
Bi.pidlroot = NULL;
Bi.pszdisplayname = szpath;
Bi.lpsztitle = "Please select the directory to be packaged:";
bi.ulflags = 0;
BI.LPFN = NULL;
Bi.lparam = 0;
bi.iimage = 0;
Pop-up Select Directory dialog box
Lpitemidlist LP = SHBrowseForFolder (&BI);

if (LP && SHGetPathFromIDList (LP, szpath))
{
Str. Format ("Selected directory is%s", szpath);
AfxMessageBox (str);


}
Else
AfxMessageBox ("Invalid directory, please re-select");
}

Select File dialog box

CString Cdcpackerdlg::bootopendialog ()//Return the selected file name
{
CString strfile = _t ("");

CFileDialog dlgfile (TRUE, NULL, NULL, OFN_HIDEREADONLY, _t ("Describe Files (*.cfg) |*.cfg| All Files (*. *) |*.*| | "), NULL);

if (Dlgfile.domodal ())
{
strfile = Dlgfile.getpathname ();
}

return strfile;
}

Load File button
void Cdcpackerdlg::onbnclickedselectdec ()
{
Todo:add your control notification handler code here
M_strdescpath = ""; member variables of the class

Open File dialog box, select the file, and return to its path
M_strdescpath = Bootopendialog ();


}
