Usage of GetOpenFileName() API in VC++ for opening a folder & NOT a file

问题

BOOL WINAPI GetOpenFileName( Inout LPOPENFILENAME lpofn );

is used for opening a file in a VC++ program, say

C:\Hello\World\abc.txt

. But I want to use this function to select a folder

C:\Hello\World instaed of a file in it.

I guess I need to make some changes to the members of the structure "OPENFILENAME". Can anyone kindly lemme know how do I achieve this in a VC++ program. Thanks in advance.

回答1:

GetOpenFileName does not support folder selection at all.

Your options are:

• SHBrowseForFolder which is available on Windows 2000 and later, but looks a bit ugly.
• IFileDialog which is the platform native folder chooser, but only available on Vista or later. To make the dialog behave as a folder picker, pass FOS_PICKFOLDERS to SetOptions.

In my opinion the best result for the user is to use IFileDialog where available, but fall back to SHBrowseForFolder for older operating systems.

There's ShBrowseForFolder. Plenty of C++ examples around if you search.
