How to convert LPITEMIDLIST to CSIDL

[Robin Shalimov]

Hi!

Could somebody please help...

I have an LPITEMIDLIST returned by ::SHBrowserForFolder().

If it's not a virtual folder, I use ::SHGetPathFromIDList() to get the path.

But if it IS a virtual folder, the above-mentioned func returns an empty string.

How can I get a pathname to a virtual folder returned by ::SHBrowserForFolder?

Thanks :)

Hi,

try to do something like this:

LPITEMIDLIST il = SHBrowseForFolder(&bi);

if ( SHGetPathFromIDList(il,szDirName) )
sRes = CString(szDirName);
else
{
IShellFolder *ppshf = NULL;
HRESULT hr = SHGetDesktopFolder(&ppshf);
if ( SUCCEEDED(hr) )
{
IShellFolder *psfOut = NULL;
hr = ppshf->BindToObject(il,0,IID_IShellFolder,(void**)&psfOut);
if (SUCCEEDED(hr))
{
STRRET str;
TCHAR szDisplayName[MAX_PATH];
ppshf->GetDisplayNameOf(il,SHGDN_NORMAL, &str);
switch (str.uType)
{
case STRRET_CSTR:
TRACE("Folder is %s\n",str.cStr);
break;
case STRRET_WSTR:
{
char *pBuffer = NULL;
int nLen = WideCharToMultiByte(CP_ACP,0,str.pOleStr,-1,pBuffer,0,0,0);
if ( nLen )
{
pBuffer = new char[nLen];
WideCharToMultiByte(CP_ACP,0,str.pOleStr,-1,pBuffer,nLen,0,0);
TRACE("Folder is %s\n",pBuffer);
delete [] pBuffer;
pBuffer = NULL;
}
}
}
psfOut->Release();
}
}

Hi! And thanks for the answer :)

It returns sth like "Control Panel", or "My computer" but not the path. Anyway, I found out how to open virtual folders.

::ShellExecuteEx().

How to "convert" the PIDL returned by ::SHBrowseForFolder() to a CSIDL_XXX value is another question :)

Anyway, I guess I can call ::SHGetSpecialFolderLocation() in a loop, comparing the PIDL returned to my PIDL (returned by ::SHBrowseForFolder()).

Maybe there're some other ways...
