• .NET Development Run Time Error - <class> is hiding inherited members but has different custom attributes

  The program is part of the backend of an ASP .NET webapp that was developed in .NET v1.1. We are now trying to make the port on the server from Windows 2000 and .NET v1.1 to Windows 2003 and .NET v2.0. Without changing the code, only recompiling in .NET 2.0, it now throws this error: Member 'Result.PhysicalMachines' hides inherited member 'ResultBase.PhysicalMachines', but has different custom attributes.

• Visual Studio Team System Load Testing

  I'm trying to load test a website that requires authentication. I see when you create a load test you can select the number of concurrent users you want to use to test the site. I don't understand how you can setup a list of userids and password to use for a load test seeing that my site requires a logon. Currently I have six webtests defined and each webtest is binded to a database that contains userid's and passwords to run each test. sounds to me that you need to create a data-driven webtest. You basically have to create the test, so you need to be able to login successfully once. Then you bind the username and password fields to a datasource, and modify the localtestrun.testrunconfig to use " ...Show All

• Software Development for Windows Vista In July CTP, using StateMachineWorkflowInstance to obtain CurrentState freezes workflows in that State

  Dear all, I have a working StateMachineWorkflow hosted under asp.net 2.0. I have written a simple routine (shown below) to interrogate the current state of a workflowinstance: public string WfCurrentStateDescription(string WorkflowInstanceId) { // Get the workflowRuntime which was started in global.asax WorkflowRuntime wfRuntime = (WorkflowRuntime)Application[WorkflowRuntimeKey]; StateMachineWorkflowInstance wfInst = new StateMachineWorkflowInstance(wfRuntime, new Guid(WorkflowInstanceId)); return wfInst.CurrentState.Description; } I find that, once I have called this on a workflowinstance, that instance gets "stuck" in the current state and never transitions to the next state, even though code appears to get c ...Show All

• Smart Device Development Designer issues after CF2.0 SP1 installation

  I just installed the CF2.0 SP1 patch. Seeing other posts, I uninstalled the Beta 1 version I had used in developing some apps (because I needed more control over the datagrid), reinstalled the original CF2.0 from my DVD, and then loaded the SP1 patch. Initially, everything in my projects looked fine. However, after rebooting my machine later in the day, I now get designer errors on any form with a grid control. The main part of the message is: Could not load type 'System.Windows.Forms.DataGrid' from assembly 'System.Windows.Forms.DataGrid, Version=2.0.0.0, Culture=neutral, PublicKeyToken=969db8053d3322ac, Retargetable=Yes'.

• Visual Studio 2008 (Pre-release) including web browser control in xaml window

  I need to included the Visual Earth control in my XAML project (I.e. One window, with gui controls and the Visual Earth control). Right now, the Visual earth control needs to run in the web browser control. I can use VS2005, create a winform, and drop the web browser control into it decorate the area around with my controls. However, sparkle, and XAML windows don't seem to support direct placement of the web browser control into a XAML window. Is there some sort of container that I could use inside of a XAML window so that I could have a integrated unified look & feel for these sort of controls that XAML does not natively support Hi Dr./Matt, I attempted the approach Matt is referring to last week. However, the problem that I ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Two big doubts on XNA Beta 2

  1) On XNA help a read: "Dynamic run-time D3DX Mesh loading is not available in the XNA Framework, so an MDX application using D3DX mesh functions, animation controllers, of x-file mesh loading will require game-specific implementation of this functionality." So this is not a quick work make this kind of coding by our self (loading AnimationSet with custom importer, animation controller functionality like mixing two animations and more) and with code optimizations (MMX, SSE, 3DNOW). Model class has just Bones with their transform. The question: now XNA don't have animation controllers because it is Beta 2, or also final release don't have it at all 2) Runtime model loading will be more simple/quick to coding in final release or will be li ...Show All

• .NET Development winForm User Control and JavaScript

  Hi, I have created a simple user control( as win dll in .net, referred to 'Embedding WinForm controls in IE').

When I use this control in my Win Apps ( as a client) i am able to register the event and handle it. BUT, the problem comes when I am trying to embed it in my web page(a simple html file) using <Object> tag ( as we use to do it for ActiveX ea ...Show All
