Empty dialog box in Windows Vista PE

Hello to all,

many thanks for the great program Tucan.

I want to use the program Tucan in Windows Vista PE.

By opening the dialog box “select a folder” you get an empty dialog box.
In this dialog box you can't enter a target folder.

Probably there is missing a DLL of the Internet Explorer wich
is not available in Windows Vista PE.
Is there a way to use an other dialog box or use this
empty dialog box with other parameter for the DLL-Call.

I am not a Windows Shell expert but I suppose that you use
an API function like SHBrowseForFolder.
This function retuns data in Windows Vista PE only
if a valid drive will be specified e.g. C:. or
with some parameter that show on my computer.

The parameter for my computer is "::{20D04FE0-3AEA-1069-A2D8-08002B30309D}".

I have heard that there is also another function
SHGetSpecialFolderLocation(Handle, CSIDL_DRIVES, BI.pidlRoot
which would be able to point at "Computer".
This should be working in Windows Vista PE.

I don't want to use DLLs or program parts out of the Vista DVD
or out of the Windows XP CD.

Many thanks from Germany
