in case you still need it...
this worked for me...

C#

[DllImport("ieframe.dll", SetLastError = true, CharSet = CharSet.Unicode)]
public static extern Win32Error IEGetWriteableFolderPath(ref Guid clsidFolderID, ref string lppwstrPath);

(Win32Error is just an enum to wrap error codes)

let me know if you need the code for this crazy protection-mode...

Calling IEGetWriteableFolderPath()
23-May-10

Hi,

I am trying to call IEGetWriteableFolderPath() from a C# BHO.
So I have done this:

[DllImport("ieframe.dll")]
public static extern int IEGetWriteableFolderPath(ref Guid
clsidFolderID, StringBuilder str);

Later in a function:

Guid FOLDERID_InternetCache1 = new
Guid("{352481E8-33BE-4251-BA85-6007CAEDCF9D}");

StringBuilder Path = new StringBuilder();

int RES = IEGetWriteableFolderPath(ref FOLDERID_InternetCache1,
Path);

But I am not getting anything in Path!
Also the return value (RES) is -2147467623 , do not know what this value means.

The Original function Signature is:
HRESULT IEGetWriteableFolderPath(GUID clsidFolderID,LPWSTR *lppwstrPath);

Please help me.

Thanks
