Question:
I define a user-defined type as follow..

Type Complex   Re As Double   Im As DoubleEnd Type

I created a function like this…

Function CompAdd( a As Complex, b As Complex ) As Complex   CompAdd.Re = a.Re + b.Re   CompAdd.Im = a.Im + b.ImEnd Function

I’m now using the Visual Basic 4.0. When I use this function by following by the following statement…

Dim c,d,e As Complexe = CompAdd( c, d )

the complier always say that variable ‘c’ is ‘ByRef argument type mismatch’.Do you have any suggestion to my problem? Thank you for your kind attention.

Answer:
You’re probably getting the error because the Dim x, y, z as Complex probably isn’t working right. Try doing it as individual lines:

Dim c as ComplexDim d as ComplexDim e as Complex

That should take care of the problem. Basically, you are telling it to dim c and d as integers, and e as complex. It’s a little strange, but I’ve seen this problem too.
