  Will you be able to create a main menu and if you can how will it be done We won't be providing a set of GUI classes in the first release. This is something that we will provide in a future release. I expect we'll see some community created gui systems at some point, probably sooner than later. :) One of my demos for the component model was creating a simple "main menu" component. I could probably release that as a tutorial on my blog. ...Show All

• .NET Development How can I get my asp.net application faster with .net CLR

  Hi gurus, how can I optimize any asp.net application's speed with the help of using CLR. What rules should follow to do that any articles or checklist is required Cheers Agha, Unfortunately there isnt a silver bullet that will help managed applications run faster. Performance Optimization is done on several levels, not just the CLR. Infact in my experience, 99% of the cases run fine with the default CLR settings. Is there a specific performance problem you are facing Here is a basic guide to some elementary ASP.NET perf tuning. http://samples.gotdotnet.com/quickstart/aspplus/doc/perftuning.aspx For GC/Memory tuning look up Maonis blog at http://blogs.msdn.com/maoni/ There is an interesti ...Show All

• Visual Studio 2008 (Pre-release) Setting Width and Height of User Control

  Hi , How can I set the Height and Width of a User Control so that it increases or decreases depending on the height and width of the parent control. I have created a Custom control with a Canvas and placed this control in a Tab Item. I am unable the set the Width when I resize the Tab Item (this is again in a Grid Splitter). I tried using the ActualWidth Property .. how ever that value seems to be NaN. Thanks for the help. Thanks Lee, but that does not seem to be working. As you said I placed the control in Grid: < TabItem Header = " My Control " > < Grid > < local:MyUserControl Width = " 500 " Height = " 500 " /> </ ...Show All

• Visual Studio Team System Load test of a web site that requires each user to be logged only once

  I'm trying to load test a web site that requires each user to be logged only once (an user cannot log on more than once at the same time), using WebTest coded as C#. Is it possible to run such a load test for <n> users from a single PC If yes, a) can the WebTest get some information from the load test as to which of the <n> users this particular WebTest is running for [I can then give (hard-code) different usercodes/passwords in the WebTest, depending on the user-number] b) when a load test is performed by selecting more than one scenario, is there a way to ensure that each of the selected scenarios only has one instance running at a given point in time [the idea is to single thread a set of test scenarios in a l ...Show All

• Software Development for Windows Vista DLL registration fails on Windows vista

  Hi, i am in process of upgrading a DLL application from VS 2003(Windows 2003) to VS 2005 on Windows vista platform. There is a post build event for registering the DLL. This fails with error code "0x80070005". When i try to register this DLL through command prompt, it fails with the same error code. With reference to all forum discussions, i disabled UAC on vista and tried registering the DLL through command prompt. This time it fails with the error code "0x800703f2". There is absolutely no way i can find out about this new error code on the net. Can somebody help me resolve this P.S. : i am running VS 2K5 as an administrator and also i have administrative privileges for my login. Thanks in ...Show All

• Visual Basic How can I cycle through all the System.Drawing.Colors?

  I worked out the Console version to cycle through all 16 available colors: Sub Main() Dim x, y As Integer For x = 0 To 15 Console.BackgroundColor = CType(x, ConsoleColor) Console.Clear() For y = 0 To 15 Console.ForegroundColor = CType(y, ConsoleColor) Console.WriteLine("Background: {0}; Foreground: {1}", x, y) Next y Console.ReadLine() Next x Console.ResetColor() Console.Clear() Console.WriteLine() End Sub I also worked out a program that cycles through 4 colors in a Windows form: Private Sub btnCycle_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCycle.Click Static x As Integer x = x + 1 If x = 5 Then x ...Show All

• Visual Studio Custom editor coloring

  I've managed to get custom colors working and my custom colors to appear in the options dialog list, but the editor windows are not always updated after the colors are changed in the VS options window. I have to exit and restart VS in order for the new colors to be used. The docs for Colorizable item allude to something more that needs to be done to support this. In the Remarks section: "The ideal place to construct an array of custom colors is in the constructor of your implementation of the LanguageService class. If you support customiztion of the colors, then you would initialize this array in LanguageService.CreateDocumentProperties after the DocumentProperties object was created." Why would I initialize this arra ...Show All

• Visual Studio 2008 (Pre-release) DrawImage "InterpolationMode" in WPF?

  I need to control the interpolation of a BitmapSource when it is rendered to the screen - I have an application requirement that says the images must be interpolated using nearest-neighbor when resized. I have fruitlessly looked for something in WPF corresponding to System.Drawing.Drawing2D.InterpolationMode. The closest I have gotten is RenderOptions.SetBitmapScalingMode(...,...) but it does not do nearest-neighbor interpolation. Any ideas Seems strange that the interpolation-options would not be available in WPF. Thanks, Andreas Hallberg David Teitlebaum MSFT wrote: Offhand, the only way I can think of to get nearest neighbor in WPF would be to figure out what the final size of the ...Show All
