Inherits HTMLDocumentEvents
May 17, 2011
I'm translating from C# to vb.net and this flags as an error: Classes can only inherit from other classes.
on this 3rd line:
Namespace Microsoft.Expression.Web.AddIn
Public MustInherit Class DocumentEventHandler
Inherits HTMLDocumentEvents
Implements IDisposable
Any idea where this class is? Do I need to import
This is the whole code:
' Copyright (C) Microsoft Corporation. All rights reserved.
'
' Description:
' AddInDocEvent handler - Subclassed from DocumentEventHandler with
' the document events the add-in cares about overridden
[CODE]...
I'm not understanding why its not seeing any of the objects or methods under Microsoft.Expression.Web.Interop.Designer ?

I think I remember reading somewhere that it was possible to assign items to a variable if the item inherited from a base class, but I can't remember how.
I want to have a class that gets properties set and one of the properties is an error code property. I want to assign any exceptions that occur to the property, but it could be any type of exception. I remember that all exceptions inherit from the Exception class.
How can I assign an exception to a property based on the class it inherits from?

inherit from two classes in VB.net?We are developing Custom User Controls that inherits from say System.Web.UI.WebControls.Label. We are planning on implementing a bunch of these controls but they will share mostly the same additional properties. We are hopeful about centralising these properties.I have looked into interfaces but it seems they only 'contract' properties you need to implement.

I'm extending the ComboBox class in VB.NET and I'm running into a problem prepopulating the collection. I try to do so by using Me.Items.Add() calls in the New() sub. However, once I place the control on a form in the form designer, Visual Studio automatically adds those items to the collection in form designer, then they are added again at runtime. How can I make them only added once?

But in my form I have a timer that generates a new value for the gauge.[code]For some reason the refresh doesn't work. The gauge doesn't change, the overriden onpaint doesn't get triggerd again. anybody has any idea why?

I want to create a User-Control that inherits the functionality of a TabContol.
I begin by starting a new project of the type Windows Form Control Library. Next I place a TabControl on the UserControl designer surface and Dock the TabContol to Fill the UserControl.
I go to the code editor for the UserControl and enter the following line of code.
Inherits System.Windows.Form.TabControl
Then I run the program and get an error. Intellisence recommends that I use one of two recomendation. When I accept the recommendation I and try to run the program the problems esculate.
The design-surface is no longer accessable.
I try to comment out the problem lines of code in the UserControl1.Designer.VB file but that doesn't help.
How can I create a UserControl that Inherits the Properties of the TabControl so that the properties of the TabControl are visable in the Properties Window?

I have created 3 classes which inherits from(System.Collections.Specialized.NameObjectCollectionBase)
The first class "SQLCommandsCollection" stores "SQLCommands" in a collection.
The second class "SQLTableNamesCollection" stores "SQLCommandsCollection" objects in its collection.The Third class "SQLDBNamesCollection" stores "SQLTableNamesCollection" objects in its collection.
Ultimately I will sit with a "SQLDBNamesCollection" collection which contains all Table names and its respective SQLCommand objects.
I would like to store this "SQLDBNamesCollection" object in my.settings("QueryViewerQueriesPerTableNamePerDBName")
at runtime but I am unsure what this settings type should be.
I have tried system.oject but this does not seem to work as I get an "Unable to cast object of type 'System.String' to type 'Fusion.SQLTableNamesCollection'" exception when I try to retrieve from settings. See below code.

When I write the following statement in VB.Net (C# is my normal language), I get an "end of statement expected" referring to the "Implements" statement.
<Serializable()> _
<XmlSchemaProvider("EtgSchema")> _
Public Class SerializeableEntity(Of T As {Class, ISerializable, New}) _
Implements IXmlSerializable, ISerializable
...
End Class
The C# version that I'm trying to emulate is:
[Serializable]
[XmlSchemaProvider("MySchema")]
public class SerializableEntity<T> : IXmlSerializable, ISerializable where T : class, new()
{

So, I'm working on a custom LitBox that accepts custom items. needed the item collection to be more than just strings, I needed to be able to store avalue to display in the listbox and an associated value (Property: Text) that holds an index value (Property: Tag) of DataTable I'm working with.I have created the new item (iListBoxItem) and the collection (iListBoxItemCollection) and have modified everything so that I can do normal Collection type methods (Add, InsertAt, RemoveAt, etc) to this collection.

I have a window service that Inherits System.ServiceProcess.ServiceBase. While running in debug mode (havent tested compiled), the thread does not see the current user credentials. I need the credentials so I can set up the WebProxy and I would prefer to use the account that service is running under instead of passing the user and pwd as a string.Can someone help me figure out why the code running in the class the inherits from ServiceBase does not have have the credentials of the logged in user?

I've been creating short test apps repeatedly to try to understand some of the concepts in VB.NET.For the most part it has been illuminating.I read Bucky's .NET knowlegebase tutorial on passing objects as parameters to newly created forms. He shows how to create a new class that inherits from the base form class and define a New() method with parameters Extending the concept I thought about doing the same thing with a form that was created at design-time (In this case Form2).

I want to create a server control that inherits System.Web.UI.WebControls.Button but gives it special capability, now what do i mean? i want my button to be a confiorm button that will work like so:
Renders to the page as a button of lets say cancel after the user clicks it i want to catch the click event (within the server control) and now after the click makeing the button not visible and makeing some kind of content placeholder (that will render from the server control) visible. that content place holder will have 2 buttons inside of it: yes and cancel. I want the programmer that adds this control to be able to register a function to the click event of the yes button. and the second cancel confirmation button should make the first button appear agian. (i know how to do this all in the client side but this time i need it all as server events)
My question is this: how do i catch the click event? i want it all to be handled inside the server control itself. so a programmer that adds this control wont have to worry about anything but just needs to register to the click event of the "yes" button.

I am currently working on my own "Colored textbox control" which inherits from the RichTextBox. What does the "Lines" property do? Does it generate the return array internally, or is it just passing back an array that is internally stored?
[Code]...
Can I skip the generation of "lines" and just use Me.Lines(i) etc. everywhere?The reason I ask is that I want to minimize the lag of the control, and I have to read all or a range of lines fairly commonly.

I am trying to create a class in VB.NET which inherits a base abstract class and also implements an interface. The interface declares a string property called Description. The base class contains a string property called Description. The main class inherits the base class and implements the interface. The existence of the Description property in the base class fulfills the interface requirements. This works fine in C# but causes issues in VB.NET.

I'm looking at the Interop UserControl mechanism that's part of the "Interop Forms Toolkit" version 2.0. (This you to build a .Net UserControl that can be published as a COM object for use on VB6 forms.)
I've started a new project using the "VB6 Interop UserControl" template, and what I see is a class definition that looks like this:
<ComClass(InteropUserControl.ClassId, InteropUserControl.InterfaceId,
InteropUserControl.EventsId)> _
Public Class InteropUserControl
[Code]....
without any "Inherits" statement. But if I look in the Class Browser, I can see that this class (not surprisingly) inherits from the WinForms UserControl class. How can it be that the "Inherits UserControl" piece of the class declaration isn't visible anywhere?
Question 634559 also shows an InteropUserControl class declaration without any "inherits UserControl" statement. I must be missing something simple from my VB.Net knowledge. (I do most of my .Net work in C#.)

I have a base class called PageBase and then a derived class TestPage that inherits from PageBase. In PageBase I have overridden the OnInit() and when it is called and I inspect the value of 'Me', it is of the type of the derived class and not the base class. My question is how does inheritance really work? For instance, when instantiating TestPage does an instance of PageBase get created too?
Here is my code;
Partial Public Class TestPage
Inherits PageBase
Public Sub New()
