hi Vandana,
Can U tell us what Dll are U trying to call in Ur application ?
I'm not quite sure, but I think sometimes U can define the datatype as "Adapt to Type" in case of ambiguity, like the situation wherein U need to pass a numeric array which can be Signed or Unsigned or Double.
Also see the Data format ring in teh CLF configure window, U can see the thing "Poinnters to Handles".
Try like this & update here, experts will surely help U out better than me.
Partha.
