If you want to select a file and only get it's path, just scan the filename string backwards until you find the first backslash. Place a 0 byte after it and you'll have the file's path.
Or use the nFileOffset member of the OPENFILENAME struct. This member is a zero-based index in the filename of the file part.

However if your goal is to let the user select a directory only (not necessarily a file), you probably need some hook. An alternative is to use the masm32 lib function BrowseForFolder, which will show a common dialog with a folder list and return the path of the folder selected by the user.

Why not?

// assuming you are using C++

extern "C" bool __stdcall BrowseForFolder(HWND hParent, char *lpBuffer, char *lpTitle, char *lpString);

Or use the C version:

// lpTitle not implemented

bool browseForFolder(HWND hParent, char *lpBuffer, char *lpString)

{

    LPITEMIDLIST lpIDList;

    BROWSEINFO      bi;

    bool        retval;

    lpBuffer[0]=0;

    bi.hwndOwner = hParent;

    bi.pidlRoot = 0;

    bi.pszDisplayName = 0;

    bi.lpszTitle = lpString;

    bi.ulFlags = BIF_RETURNONLYFSDIRS | BIF_DONTGOBELOWDOMAIN;

    bi.lpfn  = NULL;

    bi.iImage = 0;

    if (lpIDList = SHBrowseForFolder(&bi))

    {

        SHGetPathFromIDList(lpIDList, lpBuffer);    

        retval = true;

    }

    else

    {

        retval = false;

    }

    

    CoTaskMemFree(lpIDList);

    return retval;

}
