  In the editor, I can view the code of my forms, but can't use the designer view.

• .NET Development Common Question: How can I clean a machine which has the .NET Framework 2.0 or 1.1?

• Visual C# cannot ad object to ArrayList

  Hi, I'm trying to build an arraylist of objects. the code snippit is; assetClass newAsset = new assetClass(); newAsset.setSymbol(Symbol); newAsset.loadHistory(AssetDataFolder); assetList.Insert(0, newAsset); the errormessage is: NullReferencException was unhandled by user code Object reference not set to an instance fo an object I'm somewhat new to C#, but I don't see how newAsset above is not an object. I'm having the same problem with the same logic in a different session. Could the problem be that the scope of newAsset is local to the method Do I need a static object If so, it's not obvious by in the documentation. Randy Long make sure ...Show All

• Windows Forms ListBox control changes selection on MouseDown, not MouseClick - can this be changed?

  Hi all, I have a class that inherits from ListBox and provides drag/drop functionality. I'm finding that selecting multiple items to drag is frustrating, because ListBox doesn't handle a "multi-select-followed-by-drag" operation in quite the same way as ListView (or, eg. Windows Explorer) Try this: Open your "My Documents" folder, select a file. Hold down Ctrl and click a few more to add them to the selection. Now - if you mouse-down (ie. click but don't release) the left button on one of the selected items, it'll allow you to pick them up and drag them. The item selection doesn't change until you release the mouse button. The WinForms ListView control also behaves this way, but the ListBox control appears to u ...Show All

• .NET Development Implementing a Clustered NT Service

  Hi, I'm developing a NT Service using .NET 2.0, its a multithreaded TCP server, this service will handle connections from many enterprise applications. The challenge is to avoid a single-point-of-failure. My first idea was create a service instance capable of just redirect incoming calls to service instances which implement the concrete service. This solution decrease service unavailability risk, but AFAIK real cluster services like App Center uses another approach, it creates a virtual server that can redirect incoming calls to an available server, this approach really solve the single-point-of-failure problem. I'd like to use the same solution, how it can be done Thanks for any help ! ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Do all DX10 cards support SM4

  [original question from split thread http://forums.microsoft.com/MSDN/showpost.aspx postid=1274336&siteid=1 ]  As a sidenote, if you know, could you explain to me the relationship between Shader Model 3.0/4.0 and DirectX9/10. I've read the documentation, but am a little confused. If a motherboard supports DirectX 10, does it automatically have support for SM4.0, or can it be DX10 and still only have support for SM3.0   Actually, there is a case where some new motherboards support DirectX 10. The Intel, DG965WH says in its manual:   http://www.intel.com/design/motherbd/wh/wh_documentation.htm that it does support DirectX 10 through the onboard video chipset X3000.
