I am converting an old Vb6 solution to .net 2.0 in vs2010. I've been working in C# for about 3 years now and .net for 5. I don't recall having this problem in C#, but if I want initialize a readonly collection of DerivedControlFoo Is there a clean way to do it besides creating a sub to do it all off somewhere else? I'd love to be able to do it at the class level at the declaration for readability and simplicity.

I've created a component whose name I'd like to be able to change while editing in the component tray. I've added a Designer action for a name property, but now I'm stuck.
Looking at the property grid, I can see that the name property is parenthesised, indicating that it's not a regular property.

View 4 RepliesIs there a good web browser component for VB.NET that has all the features of the regular one? This includes printing and progress bar support. I've tried WebKit.NET, but it didn't have progress bar support. I also tried xlurunner but it had no printing support. Is there another web browser component that has both printing support and progressbar support? I shouldn't have to omit features from my browser just to get a better rendering engine.

View 2 RepliesI'm making some archeology, dealing with COM+I managed to enlist a simple COM dll as a COM+ component, so far so good.So I've got this 'foobar' com+ component, with it's interface, and the method I'd like to call.My question is then rally simple: how am I supposed to make a call to this component?.NET or VB6 answer is accepted (I have to check the component is OK, don't care about the client)
Edit (06/03/09): Well, I'm confused. so as to work properly, my COM+ component needs it's dll to be registered. Why not? But then, how to be sure I'm making a COM+ call, and not a COM one?
I have a function to determine the correct time that appears to function correctly, but I must be making some mistake in the "calling" of the function. This is the first time I have tried use a component and it shows.

View 2 Repliesi have just quick question (there's not much to elaborate from OP site). Have you any links or ideas, or experiences, what is to be done to class derived from System.ComponentModel.Component, in order to show its rectangle in designed form or control. I maybe satified with just making Component shapy. Anything else should be just game. But actually I have no idea how to draw component from its basics. Any idea or link, or bunch of links very welcomed! Even my capabilities of crunching google links are nothing here.

But I can't say they're straightforward. First link looks good, though its C# WinForms realization doesn't allow simple re-using in VB.NET project without conversion.I only need to burn a list of files to a CD/DVD and that's it. Any thoughts? Freeware/open-source is preferred.
I didnt know if this was the correct location to post this kind of question. My code is in C# however I am using the visualBasic. Interaction. CreateObject to connect to a OCX file. I notice that this works great for a while but if it continues to do its job for lets say a few days then I get and exception... "Can not create an ActiveX component." I am 100% sure that the ocx and dlls are registed correctly to the system.

View 1 RepliesI am developing a VB2008 application that makes use of the Office Access runtime.I started development on Win7 64-bit & Visa 32-bit machines.The application runs just fine on the machines with VB2008 installed.I have used a number of tools to build the application installation and I am running into the same thing on all target test machines (currently XP Pro).The system fails when the Office Access portion of the code starts to run.Below is the Just-In-Time debug info.
I also notice that .NET 2 is being called.Is it wise to make .Net3x the preferred .Net client?In the application, I have specificed .Net3 (however, it does not look like it is being called).The target test machine (XP Pro) has .Net 2.3 and 4 installed.See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

How do you create your own custom component for vb.net 2008? I want it to simply output to a .dll, not a whole winforms app.
How can I control the component? For example, I want my component to not have a visible design view, I want it to stay below like the stopwatch component and the notifyicon component and such, it is not something to be designed. Then, how do I edit the possible properties a user can control, and make them effect the end result?
I've been trying to figure out how to get this control to work for over a week. It can be found here: A Professional Calendar/Agenda View That You Will Use - CodeProject. It's a calendar/scheduler control that was designed using c# and I'm trying to use it in my vb.net app. I've sucessfully created a dll and have referenced that dll in my project and am able to see the controls in the toolbox as well as put them on my form. My problem is that I can't get ANY of the code that I wrote in the form to fire. No event handlers will work, not even the form_load which handles the mybase.load event. Nada. f a reason that this might be? How do I sucessfully add a handler to the events? I've used <code> addhandler monthView1.SelectionChanged, addressof (and nothing I put here ever works) </code>
