Problem:
This KB is an add-on to the demonstration GetDirectory.zip
available on MF Net Express samples page
http://supportline.microfocus.com/examplesandutilities/nesamp.asp#Win32API
"
"This program demonstrates the use of Win32 API calls SHBrowseForFolder and SHGetPathFromIDList to display a dialog box that will allow the user to select a directory.
"
____________________________________________________________
This amended demonstration allows to browse for FOLDERS and FILES
from the Desktop and from the Current Folder

Resolution:
The add-ons are:
This amended demonstration allows to browse for FOLDERS and FILES
from the Desktop and from the Current Folder
===============
The content of the structure BROWSEINFO used by the MS API SHBrowseForFolder
MS API SHBrowseForFolder http://msdn2.microsoft.com/en-us/library/bb762115(VS.85).aspx
MS BROWSEINFO structure http://msdn2.microsoft.com/en-us/library/bb773205(VS.85).aspx
BROWSEINFO structure:
typedef struct _browseinfo {
HWND hwndOwner;
PCIDLIST_ABSOLUTE pidlRoot;
LPTSTR pszDisplayName;
LPCTSTR lpszTitle;
UINT ulFlags;
BFFCALLBACK lpfn;
LPARAM lParam;
int iImage;
} BROWSEINFO, *PBROWSEINFO, *LPBROWSEINFO;
1) Being able to Browse for Folders and Files
setting the ulFlags to BIF_BROWSEINCLUDEFILES will allow you to browse for Folders and files
( BIF_BROWSEINCLUDEFILES )
( Version 4.71. The browse dialog box will display files as well as folders.)
2) Specifying the location of the root folder from which to start browsing
>>When the variable pidlRoot of the structure BROWSEINFO is equal to NULL,
the namespace root (the desktop folder) is used.
>>When the variable pidlRoot of the structure BROWSEINFO is NOT equal to NULL,
This PIDL (pointer to an item identifier list) specifies the location of the root folder from which to start browsing.
See , in demo attached, that the PIDL is set to the current working directory having used the MF CBL_GET_CURRENT_DIR the MS API ILCreateFromPathW
MS API ILCreateFromPathW: http://msdn2.microsoft.com/en-us/library/bb776438(VS.85).aspx
