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..

When I attempt to run a program I just finished coding I get the following message: "Error 1 Handles clause requires a WithEvents variable defined in the containing type or one of its base types." Looked it up online and still does not make sense to me. If I need to paste code or anything else let me know and I will do so ASAP.

Is there a way to simply the Handles statement? What if i want this sub to handle 20 textboxes do I have to list each textbox there? I already have a loop in my script so i can cycle through my textboxes ("TextBox" & i.text). is there anyway to use a variable or a function after handles to get all the names of the text boxes?
Private Sub textChange(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress,TextBox2.KeyPress, TextBox3.KeyPress, TextBox4.KeyPress, TextBox5.KeyPress

I'm working with legacy data, which often brings me one information splited in multiple columns. I'm trying to reproduce the following SQL query.[code]This own statement will run into the following exception:Variable 'line' of type 'SomeTable' referenced from scope '', but it is not defined. Any directions? I'm trying to avoid magic strings, but I'm always giving up to it (as using HQL the concatenation expression + like function works like a charm).

I am making a TabStrip control to hold a number of tabs just like TabControl, but only with the tabs, no page. The control has a "Tabs Collection", which stores a list of "Tab" class. "Tab" is not inherited from Control, but each tab has its events. So when the user add a "Tab" in the "Tabs Collection", each "Tab" instance should have a (Name) identifier, which user can access it in the code, and with WithEvents keyword so users can add event handlers to each "Tab". The expected out come should similar to this:
Friend TabStrip1 As TabStrip
Friend WithEvents t1 As Tab
...
Me.TabStrip1.Tabs.Add(t1)

I wanted to ask this question here rather then at the asp.net site (it takes too long to get an answer) because I think I have found a problem with how MVC 1.0 handles custom classes that implement IDataErrorInfo when using view binding. Not sure if this is a problem in v2.0 but I have never heard it mentioned.
Here's a little background, in MVC if I want to have strongly typed view, I create a class that basically holds the post information for me. MVC binds the form fields in the POST to the class properties of the same name for me automatically when I do this rather then implementing the ViewData dictionary.

I have been having some trouble today with a User-Control of mine. Is what is happening is when I try to build an application with the control in it, the Form.Designer has an Error saying that Namespace.ControlClass is not defined. I have no idea what the problem might be and hope that one of you do.The weird thing is that the Control Builds just fine and I can drag it from toolbox to the form and THAT works. Also, it works just fine in Design-time. It didn't start erroring until either, I upgraded it to VS2010 or until I changed it a bit today. If necessary, I can post it here.
