=begin
 I tried to call a method in an interface from 3rd party's API.  The interface has been successfully found by ole_query_interface, while at next step of calling the method inside, I got a segmentation fault.  And I think the parameters I passed into the method are correct.
 
 This implementation is using HP Quality Center Open Test Architecture API.
 Interface: ISupportCopyPaste
 Public Method: CopyToClipBoard
 Syntax (Visual Basic):
 	Public Function CopyToClipBoard( _
 	   ByVal IDSFilter As String, _
 	   Optional ByVal mode As Long = 0, _
 	   Optional ByVal Path As String = "" _
 	) As String
 Parameters:
 	IDSFilter 
 	Either comma separated list of ID numbers or a TDFilter.Text that qualifies the items to be copied. 
 	mode 
 	Unused 
 	Path 
 	Use when copying a folder. The path of the folder.
 Return Type:
 	The data copied to the clipboard.
 
 Codes Snippet:
 	iscp = tstsf.ole_query_interface(iid_ISupportCopyPaste)
 	clipboard = iscp.CopyToClipBoard(copied_id)
 	# or replace above one with below
 	# clipboard = iscp.CopyToClipBoard(copied_id, 0, "")
