Clean Elegant Solution To Form-class Level Component Collection Initializing Before Initialize Component?
Feb 3, 2011
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 have alot of forms here who need 10 or more seconds to load when the method InitializeComponent() starts to run. It have a lot of pics for that is too slow to load. I need to do a loading screen to show while the initializeComponent() components is running.

I am trying to write an VBA application in Excel 2010 using "Microsoft Soap Toolkit 3.0" on 64 bit Windows 7 to consume an web service. But i got an error while initializing an object of SoapClient30.
Does anybody know where to find a component for Visual Basic 2005 or 2008 that allow me to create level indicator, button, display or other special box used on a bridge of a ship? I want to simulate a small bridge of a ship and I need something that allow me to show engine power, rotation speed, level of pressure, compass and so on.
Is there a way to have a class collection of inherited types be initialized? For example, here is my code: Public Class CamryCar Property Name As String = "Camry" Property Color As String End Class Public Class RedCamry [Code] .....
I prefer this one as I don't have an extra property to deal with. But I can find a way to initialize that that list with objects of RedCamry and BlueCamry. Is it impossible or is there another way to do this?
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.
I am creating a card game and although I have a solution to my question it feels very forced and awkward. What I want to be able to do is to iterate through a collection but not necessarily start at the begnining or stop at the end.
Some details/examples. Imagine a game (I'll mentally use Spades) with 4 players.
Player 1 Deals cards to all 4 players which makes Player 2 the first to bid. The rub is that after player 4 bids, player 1 should then get his turn to bid.
Player 1 <-- Dealer Player 2 <-- First to bid Player 3 Player 4
I can't just iterate over the collection because a For each p as Player in Players would never make it back to player 1 to allow him to bid. As I said, I can make it work with some nested loops but I'm hoping someone might have a better solution. It certainly feels like there must be one. I run into more of the same as the deal moves around the table and as tricks are taken. If a more detailed example is needed, feel free to let me know.
I placed this checkbox named owner on my form. When i build the project i got the error as Quote: 'owner' conflicts with property 'owner' in the base class 'Form' and should be declared 'Shadows'
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 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 have integrated the innovative gateway (third party payment gateway) into our asp.net ( language vb.net) web application. while doing transation we are getting the following error in server.

But in my localhost am getting the failure transaction without getting any error.
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 have a DLL file i have made in VS2008...builds with no errors...but when i go to add it to my servers component services i get an error...i have attached a screen shot of where i am getting the error and what the error is...i even tried to make a simple single class dll with the following:
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 developing a Component. I'd like to do something when the component is dragged from the toolbox and dropped onto a form. For example display an about box.I don't want to annoy the developer by popping up an about box every time he refreshes his display or reloads the form.

During i configure these items, some time it will disappear but in the properties side, i still can found these items still exists. But i can't found these component in my form. I tried to add same item with same name n it show a error message box(because already exist).

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 have developed a Component and I want it to be able to detect when it's running in the IDE.
Or, let me rephrase that - I want my component to be able to detect when its parent form is running in the IDE.
I can use .DesignMode and a few other methods to detect when my component is running in the IDE (For example when my component is placed on a form etc)
But when the parent form is executed from within the IDE then .DesignMode returns false.
Is it possible for a component to detect if its parent (the form) was started via an IDE/Designer ? or via the command line/start menu or what ?
