There are no ready-made functions in the VC to select a folder, but this is often used, what should I do?
Automatic hands, full of clothing!
Using ShbrowseForfolder, the code is as follows:
#include
Int Selfolder (HWND HParent, CString & Strfolder)
{
Strfolder.empty ();
LPMalloc LPMalloc;
IF (: shgetmalloc)! = noerror) Return 0;
Char szdisplayname [_max_path];
Char szbuffer [_MAX_PATH];
Browseinfo Browseinfo;
Browseinfo.hwndowner = hparent;
Browseinfo.pidlroot = null; // set root at desktop
Browseinfo.pszdisplayName = szdisplayName;
Browseinfo.lpsztitle = "SELECT A FOLDER";
Browseinfo.ulflags = bif_returnfsancestors | Bif_Returnonlyfsdirs;
Browseinfo.lpfn = null;
Browseinfo.lparam = 0;
LPITEMIDLIST LPITEMIDLIST;
IF ((LPITEMIDLIST =: ShbrowseForfolder (& BrowseInfo))! = null)
{
// get the path of the selected folder from the itemid.
IF (: ShgetPathfromidList (LPITEMIDLIST, SZBuffer)
{
// at this point, szbuffer contains the path the user chose.
IF (SZBuffer [0] == '/ 0') Return 0;
// We Have a path in szbuffer! Return IT.
Strfolder = szbuffer;
Return 1;
}
Else Return 1; // Strresult IS Empty
LPMalloc-> Free (LPITEMIDLIST);
LPMALLOC-> Release ();
}
Return 1;
}
