I get this rather odd error, at least I don't understand it. I have defined a structure under the namespace "PCANLight":
Public Structure CANmsg
...
End Structure
PCANLight is imported in my main program:
Imports SERVs_up.PCANLight
Later in the program i use the following statement:
Dim dummy As CANmsg = Nothing
If dummy = Nothing Then
...
End If
This gives the error: Operator '=' is not defined for types SERVs_up.PCANLight.CANmsg' and 'SERVs_up.PCANLight.CANmsg'.
Do I have to overload the operator = for my structure or what?
My job is requiring some visual basic programming and i've only programmed in C#.So i have this code:

I'm getting the error: Operator '+' is not defined for types 'ControlesModificados. ControlesModificados.JQDialogEventHandler' and 'ControlesModificados. ControlesModificados.JQDialogEventHandler'. How can i write this code "commandHandler -= value" in other way so the error goes away! or how can i defined those operators for the eventhandler.

As you can see the DialogCommand is using another JQDialogHandler, so i can't just use

I am in the processing of moving an app from VB to C# but some of the classes I will just be moving to VB dlls to access from the main C# app. In doing this I am trying to get the VB dlls to utilize the main C# class lib. In this C# lib I have an abstract clase called base process, it sets up a background worker and handles all the progress tracking, errors, and even reports an ETA. To use this in a derived class in C# you would just do this...
public class SomeLongProcess : Common.Multithreading.BaseProcess
{
public void start()
[code]....
The problem is that if I do the equivelant in VB I get an error "Handles clause requires a WithEvents variable defined in the containing type of one of its base types". Well I can't do a WithEvents in the base class because it is C# so..
