Error calling Prompt method on NOTESUIWORKSPACE using Ole

I am trying to call the prompt method on NOTESUIWORKSPACE using ole, but I get an error message “Incorrect argument type: integer expected”. Here is the definition of the function from the ole viewer

[id(0x0000073d)]

VARIANT PROMPT(

            [in] short TYPE, 

            [in] VARIANT TITLE, 

            [in] VARIANT PROMPT, 

            [optional] VARIANT DEFAULT, 

            [optional] VARIANT VALUES);

and here is my code. I have tried all sorts of things, but nothing seems to be helping. Please help:

Subject: Error calling Prompt method on NOTESUIWORKSPACE using Ole

I was able to solve the issue. In case sombody else faces similar problem, here is what I had to do to resolve the issue. While creating the parameters for the “Prompt” method, I had to explicitely convert the 1st parameter to “Short” data type.

Dim wsParams() As Object = {CType(4, System.Int16), “Title”, “Message”, “1”, values}
