Read-Only Wrapper For Customized List
Dec 7, 2009
I have created a customized list (by implementing IList) where I added a few special methods. Sometimes (but not always), I only want to expose this list as read-only. To do this for normal lists, I use the Collections.ObjectModel.ReadOnlyCollection wrapper, which works fine typically. But it seems by passing my customized list through this wrapper, my added methods are no longer visible, which defeats the whole purpose of having this customized list object in the first place. How can I create a read-only version of a customized list?

At the top of my form, I have a status strip with the common "Window" dropdown that is seem in many commerical and Windows Applications. What I am attempting to do is the same that can be done in VB2010 itself. In Visual Basic, clicking the Window Dropdown allows you to choose which window is active. My whole point on this is that they are using a customized Image.Here is an image example from a program called Paint.NETIn the area of the dropdown, you can clearly see that the "Checked" images are customized. For example, Tools is showing the hammer with the glass button frame over it.What I want to know is how would I achieve this customized image set? I already know I would need at least 2 images, one for checked, one for unchecked.

I have a FolderBorwserDialog named fbdProfileDirectory and would like to start the dialog at a specific folder (other than the System.Environment.SpecialFolder options). I would like it to start in a file at "C:\Browser\". The program has created this folder and copied contents from a separate directory already. Is there a way to start FolderBrowserDialog, or a similar dialog box at a specific folder?

UPDATED: Feel like this shouldn't be that complicated, but I think I just don't know the proper name for what I'm trying to do. I'm dealing with an ASP.net project. The concept is pretty simple: I have a library that supplies some ecomm functions. One class in the libary contains functions around calculating tax. One class in the library revolves around the cart header. This class is consumed by a web project.

Suppose I have a Microsoft Expression Blend. Is it possible to create a custom control (such as a button) in MSE Blend and then import it to visual basic 2010?For example, I want to create a custom shape button (different from what is available in the toolbox in VB2010) (like for example a pen-shaped button) in MSE Blend. Can I import it to VB2010 to be used with Windows Forms Projects? If yes, how?

I'm attempting to create a customized dictionary object, because I want to add some code to the Add routine, and I can't just inherit because Add is not overridable.
So I'm creating a class that implements IDictionary. Already I am confused, because Dictionary implements a lot of interfaces, listed below:
Implements IDictionary(Of TKey, TValue), ICollection(Of KeyValuePair(Of TKey, TValue)), _
IEnumerable(Of KeyValuePair(Of TKey, TValue)), IDictionary, ICollection, _
IEnumerable, ISerializable, IDeserializationCallback
But IDictionary inherits ICollection and IEnumerable, so why implement all three (and don't they have overlapping methods)?
#2, when I implement IDictionary, the code fills in two Add methods (one for the ICollection add of a keyvaluepair, one for the Idictionary method). Apparently both these add methods are required for Idictionary, yet a regular dictionary (which implements IDictionary) only has one Add method that I can see. I actually would like to have only one Add method if possible. Why am I being asked to make two (and that's before all the other interfaces have been added)?

I am creating a windows application for my company. in the master file i will enter the number of items we are getting from the customer. and in the next page i have to enter the details of each item. For that i have created a datagrid which has one autogenerate number field and the remaining fields must be editable. So that when i enter all the values in the datagrid, it has to go and save in the data base.

I have a class clsContextPopUpMenu to create a ContextMenuStrip with some basic functions (e.g.copy) that I can use in different controls. [code] A broader question is that when should I dispose objects/resource by myself? Of course, gc collector is not a magician to release all available memory. Can I always dispose objects/resource in Dispose Sub as shown above?

In my program's properties, I customized my application icon, which I also set on the main form's icon property. If I look in my bin/Release folder or if I run my program I see my customized icon. If I right-click and select Send to -> Desktop on Windows XP, I see a shortcut with my ICON on the desktop. If I do the same thing on Windows 7, I get the default ugly icon. What should I do to get my custom icon on Windows 7 when I make a shortcut from my main EXE?

I have created a customized control in which i have used some different property names. For eg. if the actual property name in the base class is "Text", i have used the name "CtlText" by internally implementing the "text" property with some additional checks. Now i want the user to use only "CtlText" property during coding. Currently the user is able to see 2 property with same functionalities.
Is there anyway i can surpress the using of a property during runtime?In design time we can hide it using the "Browsable" attribute, but i need to hide the same during runtime also.

I'm trying to add a control on my form and each time an error pops up : "Failed to import the ActiveX control. Please ensure it is properly registered". I'm currently upgrading from VB6 to VB.NET (VB2010 running on Win 7).I installed vb6 on my win 7 PC and i can still add that control on any form - so definitely the OCX is properly registered. My guess here is that VB.NET is unable to create a COM wrapper for that OCX.

I would like to create a .exe wrapper for a Flash Player using VB.NET. I am having a few problems.1.I seem to remember being able to import Flash Player as a control into Visual Studio (2008 Pro). For some reason, I can't seem to VS to import it anymore. (I tried using the OCX from Visual Studio) Perhaps I'm looking for the wrong file. What file am I looking for?
2.Is including Flash inside of a VB program legal?
3.When a control is included in a VB.NET program (such as Flash) does the control need to be distributed in a separate file, or will the compiled application contain it in the ".exe"?
I was able to import the control as the Flash10b.ocx from c:WindowsSystem32Macromed directory as a COM component. Question 2 and 3 still remain.Is there documentation on the ActiveX control? I am trying top figure out the API for ExternalInterface.

I have a file called CalcProg.DLL written in Delphi which is used in Plaxis. I am planning to write a VB.net wrapper for this DLL. The problem is that I don't know what function names there are in the DLL. I was wondering if there was a wrapper generator so I could input a DLL and the generator generates a dummy CalcProg.vb with the function names so I could have a VB class that does something like this:

I've been working with System.Drawing for awhile and like to think I have a good handle on it; I've created classes that draw grids, write text in gridboxes and rectangles, convert rectangles to circles, fill areas with color, etc. What I don't have is any sense of artistry at all, and I don't have the slightest clue how one would use System.Drawing to draw a rectangle and then color/slope the edges so that it looks like a System.Windows.Forms.Button would, or how to make it look like it's inset deeper than the surrounding Form, like setting a Panel's BorderStyle to Fixed3D.

building a ASP.NET profile wrapper to use with an ObjectDataSource control. I would like to have the serialized profile data that I have defined in web.config be accessible via a FormView control within a user control. I'd like the users to be able to view and update their profile data. I have part of the code but am lacking the experience to complete it. I'm using a aspx page with some text boxes and having users update via a simple form now but I need something more reusable and efficient, not to mention moving the logic to a middle tier. I see that the ObjectDataSource control has some intrinsic ability to view profile common data but that seems to be limited.
Namespace SiteMemberShip
Public Class ProfileWrapper
Private FirstName As String
Private MiddleName As String
