Object

The equivalent in .NET is the Object data type (object in C#).

 

[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.UpdateStatusByMCID(MessageControlID,
Status,ErrMessage, QueueErrorMessage);

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

what should I do?

thanks

Object is the closest thing to it, since every thing in .NET - including
primitive data types - is an object, a variable of object type can point to
any data type.

You should however get used to using strongly defined types like string, int
etc and use object sparingly, for good practice if nothing else. Hard to
bebug a huge list of objects.
