Optional Object Parameter

[moonmonkey]

I'm trying to write a vb function in which the developer may or may not pass an ImageList object as the final optional parameter. The question is, how do you check to see if the object was passed or not? I've tried isnull(ObjectParameterName), isempty(ObjectParameterName), and ismissing(ObjectParameterName), but none of these methods appear to return the desired value.

Can this be done?

I cracked this one myself!

If Not ListIconsControl Is Nothing Then

'object has been passed!

end if

easy when you know how!

Love hearing that...

Note: IsMissing(ObjectParameterName) will also work if ObjectParameterName is declared as a variant parameter in the called function.
