I have created a class and want to distribute it without giving off my code/create it as an application. I am aware that components are nearly no longer used and their disadvantages. I dont need to draw anything on the ui. (I know basically components are used for this aim but I just need to try this :] )
My question is: My class uses a webbrowser because webclient and web request don't work for me. When I start vs 2010 and select new project - Class Library and include the namespace System.Windows.Forms it doesnt find it. So first of all should I select class library to create a component and how could I include the webbrowser object?
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 am searching for the Component Class. When I go to "Add New Item" ,in my project their is no Component Class Item in VS 2008. I would like to Drag and Drop control onto my new class and I can't see how to do this ?

I hear COM here and there and I want to know is COM and a COM dll the same thing, and most important: when I create a Class library project is that a COM component?

I am looking for a serial port component for .NET that overcomes the issues with the built-in Serial Port component related to sudden unplugging of USB-to-RS232 adapters, and suspension of the computer while the port is open. (Untrappable errors occurring after the the device is unplugged or the computer comes back after being suspended.)I have been using Richard Grier's solution, but I still have problems when resuming from suspend.Is there a 3rd party component that you would recommend? I have tried several, and each have their shortcomings. Ideally I'd like a drop-in replacement for the standard serial port, but I'll take whatever I can get.
Edit: It turns out that upgrading to .NET 4 and using the serial class works fine on XP, but does not work on Windows 7.
I have a DLL with me in which i have created a component class. But as long as the project is open the Tool shows in the ToolBox, but the moment i open a new project, without the DLL project opened along with it, the Toolbox does not show me the Tool/Control/Component Class , which i have created. How do I register my component so that it shows in the ToolBox, other than the usual way of Selecting by Browsing
I created a VB.NET application that takes in parameters from a javascript file, uses those parameters to then retrieve info from a database, then send back to the javascript.

I'm trying to make a Toolbox component which the user can drag onto a form in the VS Designer. The component has to recognize the Form it is on, in order to handle certain Form events. I would prefer to do it without requiring the user to add any code to the form. Does anyone know a way the component can get the identity of the form?

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.

Weird problem, it only happens for one of my clients, and it happens on all 3 of their computers. Their computers are Windows XP.My form has a Windows Media Player control on it, to play a video from the internet. When the form loads, I get an exception "External component has thrown an exception". It happens in the form's designer, in the InitializeComponent procedure, at this line:CType(Me.wmpVideo, System.ComponentModel.ISupportInitialize).EndInit()
It works great on 100 other clients computers, running XP, Vista, or 7, and this is the first person to have this issue. If I take the Windows media player out of the form, it works fine.BTW, those computers have Windows Media Player installed, I already checked.
I recently have been developing an application in .net that uses lots of components created as digital/analog input/outputs, and, when each component is clicked shows a form that shows it's state.The problem is that the form allows to change the state of the component and I don't really know how to reflect the change made in the windows to the component variables, as I don't know if there is a way to call the parent from a windows form or any similar way to do it.
Hi, I'm trying to receive email in vb.net and I found a great tutorial on how to do it. However, I need a component named ADODB and Interop.MAPI.dll to do so. Where could I find either component?
I'am Using Visual studio 2010 from 1 year , and it's work fine But Today when I tryed to open the Vs2010 an Error Msg was Appeared to me which is (Cannot Find One Or More Components please reinstall the application.)
When my application loads in Visual Studio 2010 I see this warning. Everything runs ok in it as far as I'm aware but I'm completely ignorant in this area. Could that cause me a problem and is there a way to replace that component? There is also the other warning you see in the screenshot.
Quote:Warning1Namespace or type specified in the project-level Imports 'System.Linq' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.
I did a search for the entire solution and it didn't turn up any Sysem.Linq anywhere. I looked at every Imports statement in my project and I don't have any Imports System.Linq anywhere unless it's somewhere where Visual Studio's quick find search doesn't see it.
I have a simple Win App VB project with a single form in it. I also have an Active X component which I am adding onto this form. This component is made in C++. On building the VB project i get the message "COM Reference 'CPPLib' is the interop assembly for ActiveX control 'AxCPPLib' but was marked to be linked by the compiler with the /link flag. This COM reference will be treated as a reference and will not be linked." but it compiles successfully. When i try rebuilding it or opening the view designer of the form VS2010 crashes. The project is locally creating two dlls namely "Interop.CPPLib.dll" & "AxInterop.CPPLib.dll". I have made the Embed interop types False for both these references.
