• Visual Studio 2008 (Pre-release) Problems and questions: ResourcesDictionary, styling Expander, setting width/height using % values

  Hi!, I'm having some problems and questions with/about XAML. First the problem with ResourceDictionary. I created a file called "XamlResources.xaml" with some styles in it and now I'm trying to "include" it to the MainWindow.xaml using this code (which I found from MSDN documentation): <Window.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="XamlResources.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Window.Resources> However, this results to an error "Value 'XamlResources.xaml' cannot be assigned to property 'Source'". What's wrong The XamlResources.xaml is in the same ...Show All

• SQL Server SQL Server Express won't install with default service name

  Anyone else had this problem I think I had a beta installed at some point. After a dozen attempts, I got SQL Server Express to install, but I had to change from the default service name (SQLExpress). When trying to configure the .NET samples that come with Visual Studio 2005, the ConfigSamples.exe does not recognize that I have SQL Server Express installed. I suspect this is due to my non-default service name. I have verifed that there is not a service installed (at least according the Services Admin Tool) that is named SQLExpress. I just dropped over $600 for a personal copy of 2005 Professional, and I would just like to view the samples. Someone take pity on my poor soul and help out. I promise to help you help me and show much ap ...Show All

• Visual C# Start form minimized to tray?

  Hello I want to start my application minimized to tray and only minimized to tray. I have been trying several approaches: - setting the Visible-property to false after component initialisation - calling the Hide()-function - raising an event that calls the Hide()-function if the form is visible None of these have worked. By the way in my main()-function I am creating my form like this: Application.Run(new Form1()); I also tried Form1 aForm1 = new Form1(); aForm1.Visible = false; // or aForm1.Hide(); Application.Run(aForm1); Didn't work either. Any help would be much appreciated. Sincerely Peregrin Peregrin, maybe you'll find this link helpful: http://www.windowsfo ...Show All

• .NET Development CodeDom for 'is' operator

  I would like to compare some types for membership in an inhertance tree. In C# I use the 'is' operator. VB also has a similar operator. Is there a CodeDom class that I can use to encapsulate the 'is' operator Thank you. Kevin No, Object.ReferenceEquals(obj1, obj2) "Determines whether the specified object instances are the same instance" (from MS help). This is different for the 'is' operator. var is type could be replaced by: var != null && typeof(type).IsAssignableFrom(var). More exactly: Object.ReferenceEquals(var, null) == false && ypeof(type).IsAssignableFrom(var.GetType()) The following code is on my web page:   http://metasharp.net/index.php title=M ...Show All

• Visual Studio 2008 (Pre-release) Inactivity Default value

  I've been testing for few days with the inactivityTimeout and receiveTimeout. In my WCF app, I use WSHttpBinding and WSDualHttpBinding. No matter what I set the values of inactivityTimeout and receiveTimeout to be, I get the CommunicationObjectFaultedException. My application needs to be kept alive for Infinite but that didn't seem to work so I changed to 20 minutes and still the timeout is set to 10min. What else do I need to change Description: Failed to stop service. System.ServiceModel.CommunicationObjectFaultedException: The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it is in the Faulted state. Thanks, Gina. Have you m ...Show All

• Windows Forms DataGridView AutoFilter whitepaper and sample

  Are you spoiled by the AutoFilter feature in Excel Do you want the same functionality in the DataGridView control Then my new whitepaper and sample are for you. See: http://msdn.microsoft.com/netframework/windowsforms/default.aspx pull=/library/en-us/dnwinforms/html/DtGrdVwAF.asp The DataGridViewAutoFilter library provides a custom DataGridViewColumnHeaderCell with a drop-down filter list that displays each unique value in a column, and updates the filter of the bound data source when a value is selected from the list. A custom DataGridViewColumn is also provided to make using the AutoFilter header cell easier, particularly in the Windows Forms Designer. Customizing DataGridView column header cells is not as easy as customizi ...Show All

• Visual C# namespace overlap

  Hi, Let's say assembly 1 has a namespace a.b Another assembly 2 has a namespace c.a.d ('a' just happens to be the same word, but conceptually the two namespaces are different.) In assembly 2 (i.e., within the block namespace c.a.d { } ) how do I reference the namespace in assembly 1 Is there a way to tell the compiler that when I say a.b, I want that to be within the global namespace Right now the compiler thinks I'm trying to use (the non-existant) c.a.b. Thanks! Hi you can use a namespace alias http://msdn2.microsoft.com/en-US/library/sf0df423.aspx using MyAlias = MyCompany.Proj.Nested; // Define an alias to represent a namespace. namespace MyCompany.Proj { public class MyClass { public static ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Stuttering in D3D application

  Hello, we're experiencing stuttering in our D3D game. With stuttering, I mean that the game loop will generally take 20-30 milliseconds to complete, running smoothly at ~30 fps. But then, like once per second or so, the game loop will take like 150 milliseonds or more to complete. The stuttering happens on many different computers so I don't think it's a driver/hardware/setup problem, but rather something that we're doing in our rendering that's causing the stuttering. Many other games run fine on these computers. I've profiled parts of the code.. and usually the huge delays come from D3D Present() method or the actual rendering. Does this indicate that there's a problem with the rendering command queue being filled up and stalled or somet ...Show All

• SQL Server Backup databases

  Hi I'm trying to setup a back up plan for a number of databases, I initially set up one plan to include all user databases which worked fine or so I thought, when I check them a few days later I noticed that some of the databases were not appearing in the backup set, the only way I could get these to appear is to set the comp level to 90, now when we run certain applications we get an error, when I return the comp level back to 70 then the application works fine, is there a reason I can not back up any database on sql 2005 without it being a comp level 90 Thanks inadvance I'm guessing that the maintenance plan you've created uses some feature or syntax which didn't exist in SQL 7.0 Look o ...Show All

• SQL Server Custom Connection Manger Doesn't Show Up In VS

• Windows Search Technologies WDS Problem Opening Attachments Archived With Legato Emailxtender

  We are using WDS v2.6.5 and/or 3.0 in an environment with Exchange 2003 and Outlook 2003 SP1 with cache mode enabled. We are archiving Exchange email over 90 days old and shortcutting attachments. The shortcutting modifies the message class on the email to IPM.Note.ExShortcut.owa. Working natively in Outlook, the addin "Emailxtender Launch Extension" supports pulling the attached item back from archive when the user opens the message and the attachment is available to launch. When we search for results via WDS and then launch items through its UI we get inconsistent results. In some cases the item returns from archive and works as expected. In other cases the custom message class item is opened and the attachment will not launch. ...Show All
