• Visual Studio 2008 (Pre-release) ComboBox bug

  This looks very much like a bug. ComboBox binding doesn't seem to work when the datasource is an ADO.NET DataTable. This code is based on the ExpenseIt sample where the binding is to a CLR class. < XmlDataProvider x:Key = " ComboItemsData " XPath = " /ComboItems/* " > < x:XData > < ComboItems xmlns = "" > < ComboItem Value = " 1 " Text = " Accepted " /> < ComboItem Value = " 2 " Text = " Offered " /> < ComboItem Value = " 3 " Text = " Waiting " /> </ ComboItems > ...Show All

• Software Development for Windows Vista Custom Activity - Probelm with EventSink Activity

  Hello, i tried to model a custom activity. This activity does contain of a) InvokeMethod Activity b) EventSink Activity out of the activity galery delivered. I also implemented a Service which I added to the workflow engine in order to connect the method invokation and the event sink. Then I build up a sequntial wf out of my custom activity. The method invoke activity within my custom activity works properly, but when my async. operation is finished and I want to raise the event to trigger the eventsink activity the event within the added service was null. The same scenario works fine when i model this directly within a sequential wf. Regar ...Show All

• SQL Server Deserialization Failed: Parent Columns and Child Columns don't have type-matching columns.

  After about an hour and a half of validation, my Analysis Services database has been migrated from 2000 to Analysis Services 2005. I am now receiving the error in the subject any time I try and access the Data Source View that was created. All dimensions and cubes cannot be processed. I have tried editing the xml manually to no avail. Any ideas would be much appreciated! Would still like to know what the issue is, but I found a workaround in the meantime. I manually edited the .dsv file, renamed the ids, and restarted OLAP.  I then opened the project in Business Intelligence Studio, and manually created the DSV.  ...Show All

• Visual Studio Training/consulting on VS Extensibility?

  We are a small ISV that sells a highly customizable base product, and also provide customization services to roughly half our customers. In the absence of something like VSTA in .NET for the last 4+ years, we have built our own proprietary, peculiar IDE and framework in its place. Now that VSTA is coming out, some of us at my company would like to move to it. We need training and consulting to get manager buy-in and "jump start" us on this. The older and "more conservative" at our company will kill off the effort if we do not have outside expertise that can explain and justify the VSTA approach. Where can we get thi ...Show All

• Visual C# Working with Certificate Revocation List

  I need to load CRL file (or Byte array) and retrieve the Serial numbers in. I notice that System.Security.Cryptography.X509Certificates namespace is for certificates (and I'll use it) but what namespace can I use in order to retrieve the CRL Hey http://www.bouncycastle.org/csharp/ has a Libary that can open a CRL file and run thru it. I use it to load the CRL file into a hashtable. And then use the hashtable to make lookups for the certificate to see if has been revoked. ...Show All

• Visual Studio 2008 (Pre-release) What's the soure of this 3D rendering "bug"?

  I've run into some "rendering" problems using Viewport3D. Sometimes pictures tell more (than a 1000 words) so here goes: This first image shows the rendered viewport with a blue "floor" and a red "wall". As you can see, the floor has "spilled" into the wall. http://home.comcast.net/~tlanglo/WinFX/Attachments/WallAndFloor_NotOk.png The second image shows the same wall and floor, but doesn't have the same problem (there's still some problems, though). http://home.comcast.net/~tlanglo/WinFX/Attachments/WallAndFloor_Ok.png And here's the XAML file I used in the example: http://home.comcast.net/~tlanglo/WinFX/Attachments/ ...Show All

• Visual Studio Really Frustrated With VS 2005

  I posted earlier about the fact you cannot get a copy of VS 2005 Pro even though the "launch" was 11/7. I have a Windows app I built using the VS 2005 Beta 2 that I need to update but since I downloaded the new Express editions (thinking they would work - wrong!) all the Beta 2 stuff is gone. OK, I went to my other system (Win XP SP2) and figured I'd install the VS 2005 Beta 2 there and use that until someone decides to "really" release VS 2005 Pro. No Joy. The install completed saying that it couldn't install all componets - it listed some like J# (which I never use) as failed installs. I deided to do a Repair/Reinstall - that al ...Show All

• Visual Studio Express Editions keyboard special character keys invoke wrong characters

  I may be in the wrong topics forum for this question. While cleaning up a friend's Compaq Presario 5070, I wrote a note using notepad; the keyboard letters worked fine but the special characters did not. ie: left square bracket gave me a double circumflex accent instead ( [ = ^^ ); acute accent gave me a latin small letter C with cedilla ( ' = c ); a solidus gave me a small letter e with grave ( / = e ). Could this be your software working Is there a virus or trojan in the Wild that uses this software for RAT purposes with tunneling technology The PC is circa 1999 using an AMD K6-2 chip 350 mhz and an ergonomic keyboard with Easy Button a ...Show All

• Software Development for Windows Vista Installation Issues (non-delt with)

  Hello, When I install Windows Vista Beta 5342 , It recognizes the drive needed, goes through with the Installation, and restarts as it's supposed to. After it restarts (the CD still in the machine of course) it says "hit enter to boot from CD\DCD so i hit enter. It shows up with the Windows Vista Beta installation again. I go through it and it does the same exact thing over again. (attempt 2) This time after the installation I take out my CD before it boots, and it comes up with nothing except a boot manager saying there are windows versions installed, I hit enter on both of them (at seperates boots) and they black out my scre ...Show All

• Visual Studio Team System Recommendations for Pooling Work Items?

  What does MS recommend for situations where I want to create a pool of Work Items that developers can pick and choose from I have developers A, B, and C. I have bugs and enhancements that I want to put into a pool so that who ever has the free time can take the next bug or enhancement.

• Visual C# How to access classes and properties of .dll file?

  I'm new to C#. Will someone show me how to access the classes and properties of a .dll I already have it reference in my bin folder. Once your C# project has a reference to the .dll (right click on the project in Solution Explorer and select "Add Reference...") you need to add an appropriate "using" statement to your source file to indicate which namespaces you want to use. For example, new C# projects already have a reference to System.dll, and the source files start with: using System; which allows you to use the types declared in the System namespace. You will need s ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Degraded performance when debugging MDX1.1 applications in VS2005 compared to VS2003

  Hello, I've noticed that when I'm debugging MDX1.1 applications in VS2005, they achieve a significantly lower framerate than when debugging them in VS2003. The performance decrease differs per application and seems to be somehow linked to the use of HLSL effects, as applications that use the Fixed Function Pipeline do not suffer this decrease. This morning I witnessed an extreme case of this problem with a little game that renders multiple meshes using HLSL effects. It achieved a lowly 60fps when I ran it in debug from VS2005, whereas it achieves a 550fps framerate when I just run the debug exe from Windows Explorer ...Show All
