I've got a TEXTBOX called CompanyName. And I've got a warning in the error tab that says:
WithEvents variable 'CompanyName' conflicts with property 'CompanyName' in the base class 'Control' and should be declared 'Shadows'.
Is CompanyName some kind of reserved keyword? I'm getting the same error for a textbox called Location. Can I ignore these warnings or must I rename my textboxes. My problem is the textboxes are named to match columns in a DB TABLE to allow me to do some auto-binding logic.

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 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..

How should I go about getting my mouse position over multiple controls, and such. I can't use the form_mouse move event, or any other control event nor can I use them all at the same time cause that would conflict with the actual position I need for an object.

I am creating a user control where when a user clicks a button a popup window will show up with information. The popup window is driven by a toolStripDropDown so when it shows up it does 2 things
Does not move the other controls on the form around but displays over them That it can show the details outside the bounds of the user control itself without having to reserve the space ahead of time
Here is some code
Public Class Popup
Private treeViewHost As ToolStripControlHost
Private Shadows dropDown As ToolStripDropDown
[Code].....
Now my issue is as the form moves or resizes the Tooldropdown does not move relative. I understand that. When I try to capture the move event of the user control that event does not fire when the entire form moves. There has to be something I can capture because the controls in the container of the form move relative, what drives that? I tried wndproc but nothing fires during form move unless the form is repainted.

In my project's Main form I have a picture box of size 1024*1024 which occupies almost 75% of my monitor screen. Now I have defined Picture box Mouse movement event with corresponding actions to be done for mouse mouse event over picture box. Now the problem is I have another button on my main form by pressing which an another form of size 520*170 pops up. I have set Me.Topmost property to this form. But even then if by I hover the mouse over picture box, this pop up form disappears (i.e. goes to back screen) and if at all i have to perform any action on this form I need click the Tab of the popped window on the task bar which makes this form visible. Worst case is if the user drags this form on top of the picture box and looses focus, then its impossible to get it(focus) back.

I need some help to understand my options to get this working. I try to update a textbox control by a property-changed event from a class variable. I've digged around for a day and have a vague understanding that this can be solved in three ways:
1. Using some "if InvokeRequired", "Invoke" code in the handler method
2. By programming a special delegate class for this variable
3. By using a databinding directly linking the control (textbox) to the class event
Now.. Are these options correct? And would it be possible to get some help to show these three solutions in actual code (relevant to mine)? I can't seem to manage to sort all the information to a working code. Also, what are the pros and cons of the different solutions?
As my code stands now, it's obviously none of the above, as it gives a cross-thread error, as indicated.

Background:I have a base class and several inherited derived classes. The derived classes don't always need to have the same properties. If any properties are shared among the derived classes, those properties would live at the base class level ('Contents', for example).Similarly, GoodDocument below has 'GoodThings' but would not want/need to have 'BadThings'.I want to treat instances of both 'GoodDocument' and 'BadDocument' as type 'Document'
public mustinherit class Document
public property Contents as string

What I'd like to do is in my application move a control like a groupbox or frame with content on it from e.g the main form to a tabpage on that same main form using code.
I can change the position of the control using it's location, but I haven't got a clue on how to move it from the main form to a tabpage, or from 1 tabpage to another.
-Is this at all possible and if so, how can it be achieved?

In re-engineering a windows forms application, I find that a lot of code-behind in the various form classes is duplicative and I'm trying to centralize as many procedures as possible into a base class which can be inherited and used by the subclassed forms.
This process seems to be going well and is making the code in my subclasses much simpler and hopefully easier to maintain, but I'm not sure where to draw the line between leaving code in the subclasses and engineering for generic resusability and moving it to the base class.
Specifically, in some subclasses I have code which manipulates variables and objects specific to the subclass, and although I could move the code-behind into the base class, the base class code references specific objects which are needed to compile. For example, each subclass manipulates a databound datagridview and form detail controls which allows the user to select between multi-record and detailed single-record views of a datatable.
In Visual Basic 2008 do I need to declare dummy data objects in the base class so that the base class will compile? Or is there a way to indicate that the data objects will be provided by the subclass?

when we have a method of a derived class implementing a method of an interface which is already implemented in the base class, the compiler throws a warning (by default). when i see a warning i will try to erase it and the only way to erase this warning is to mess with the settings of the compiler hence i hope that there is a way to declare "how" a method implements an interface's method. by this i meant that we should be able to declare overridable, overrides and shadows for the implements keyword. hence if we declare overridable-implement for a method of a base class implementing an interface's method, the compiler should give no warnings when we override this implementation (re-implementing in a derived class). Similarly, if the method of the base class implementing an itnerface's method was not declared as ovveridable-implement, the derived class should be able to Shadow the implementation example code which flags unnecessary warning:

I'm trying to retrieve values using vb.net from a sql database. How do I use "SqlDataSource.Select()"? Is there a way to move the value to a variable that I can use for other things? I know its kind of scattered and vague but that is the best I can do. I basically need to set a labels text to a value in a table.
