variant issue

[Guest]

My vb function in com+ is:

public Function updatestatus(byval MessageControlIDas string ,byval Status
as string,byref ErrMessage as variant, optional byval QueueErrorMessage as
string ="")as variant

I am trying to call this through com interop:

object ReturnedValue;

ReturnedValue = HVOUTInstance.updatestatus(MessageControlID,
Status,ErrMessage, QueueErrorMessage);

I get an error saying " cannot convert from 'object' to ref object'

what should I do?

thanks

Try using the ref keyword in C#.
