RE: [CFCDev] OT: CFMX and ActiveX

[Roland Collins]

I think what you mean is not that the method returns 4 parameters, but rather that it uses pointers (or pass by reference/out variables) for some of the parameters, with the expected behavior being that the variables are modified by the function.  So your method would look like this:   SomeMethod(InVar1, InVar2, *OutVar1, *OutVar2, *OutVar3, *OutVar4)   When you pass “by reference” from CF to a COM object, you need to enclose the variable name in quotes.  So your call should look like this:   <CFSET retVal = SomeMethod(myVar1, myVar2, “myVar3”, “myVar4”, “myVar5”, “myVar6”)>   I personally have avoided passing CF arrays into COM objects, so I’m not fully sure how they will behave.  If, however the method you’re calling appears when you CFDUMP an instance of the object, you shouldn’t have any problems calling it.   Take a look at the following sections in the CF docs for some specifics.             “Getting started with COM and DCOM” “Accessing Complex COM Objects using Java proxies” “Connecting to COM objects” “General COM object considerations”   Hope this helps.
