from path to ITEMIDLIST

[hepman]

hello,

I have no idea to convert that code to labview, could someone help me.
Is it possible only by code library function.
I like to use only shell32.dll

the shparse is hopefully correct and attached
LPSHELLFOLDER pShellFolder = NULL;
HRESULT hr;
ULONG chUsed;
// Get desktop IShellFolder interface
if (SHGetDesktopFolder (&pShellFolder) != NOERROR)
return FALSE; // failed



// convert the path to an ITEMIDLIST
hr = pShellFolder->ParseDisplayName (
NULL, // owner window
NULL, // reserved (must be NULL)
lpszPath, // folder name
&chUsed, // number of chars parsed
lpItemIdList, // ITEMIDLIST
NULL // attributes (can be NULL)
);

Best regards   Hepman

You have the right way in Labview with including this with call library function node.

We have no direct support for that but you can find your answer in the msdn from Microsoft

For the rest you must look in http://msdn2.microsoft.com/

http://msdn2.microsoft.com/en-US/library/ms647757.aspx is to

SHGetDesktopFolder Function

Retrieves the IShellFolder interface for the desktop folder, which is the root of the Shell's namespace.

Syntax

HRESULT SHGetDesktopFolder(          IShellFolder **ppshf
);

Parameters

ppshf

Address that receives an IShellFolder interface pointer for the desktop folder. The calling application is responsible for eventually freeing the interface by calling its IUnknown::Release method.

Return Value

Returns NOERROR if successful, or an OLE-defined error result otherwise.

So you can use Code Interface Node or Create C file in Call Library Node and use a *.c file from the Internet...
