• Software Development for Windows Vista Error while viewing the Workflow Designer

  I'm always getting the following error whenever I'm trying to open any new or existing workflow. I've downloaded all the CTP Runtime Components and Visual Studio extensions for Windows Workflow Foundation Beta 2 couple of days back. The Error: Method 'GetSelectedPropertyContext' in type 'Microsoft.Workflow.VSDesigner.ExtendedUIService' from assembly 'Microsoft.Workflow.VSDesigner, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation.

• Visual Studio Team System CTP7: Database Pro requires local SQL 2005 instance

  I checked the thread for CTP6 that discussed this requirement, but none of the suggestions I tried there worked. I have a SQLExpress 2005 instance running, but when I try to create a new SQL 2005 project, I'm still getting the error message about a local instance of SQL Server being required. I've tried leaving the option blank, filling it in with SQLExpress, and filling it in with <machinename>\SQLExpress, but I get the same error message regardless. It's pretty frustrating to go from being able to generate tons of different test data in CTP5 to not even being able to create a project in CTP7. Any help you could provide would be greatly appreciated. -Scott Hi Xzarian, as to IIS installe ...Show All

• Visual Studio 2008 (Pre-release) Problem with UDP Transport Sample

  I am still using RC1 rather than RTM because I am on a tight schedule and did not want to confuse myself unless I had to. I am having a strange problem with the UDP transport sample. It works intermittantly. No rhyme or reason. It has been very solid for several days as I added functions to my tool. Then it stopped receiving. I figured I screwed something up, so I went back to a known working backup. But that does not work either. On further investigation, it seems to work randomly, about half the time. I have an analyzer (Ethereal) hooked in, and I can see the packets arriving, they are definite addressed to the right place. I compared a packet that did not arrive with a packet that did arrive, and except for MessageID and app sequence ...Show All

• Visual C# Attribute Problem

  Hi all, I have the following problem with using attribute. I declared an attribute class (MyAttribute) with a list of properties. That attribute class is in its own dll. Now I have another class (MyClass) that referenced this attribute class. Everything works fine. But now, I want to add additional properties to the attribute class (MyAttribute). It seems that any new property I added to (MyAttribute) is not recognized by (MyClass). Another test I did was simply adding the new property to (MyAttribute) and use reflection in (MyClass) to simply list out all the attribute property, even that errors out. For some reason, it seems that once i declare an attribute class, I can't add or change it. If I add or change anything, the program t ...Show All

• Windows Forms Form-to-form communication --- events or messages?

  Hi, In my app, I want to send a message from a form I'm dragging to whichever other form in the application is "most covered" by the form I'm dragging. Since I'm new to C#, I'm just making sure I'm not sticking to old MFC habits, so...

You won't be able to run any application that uses Direct3D 10 at realtime speeds without buying a new graphics card (new as in new /then/). In previous versions of Direct3D, Microsoft had support for 'card capabilities,' which described to the application which things the card could and could not do. This meant that even the lowliest card could 'support' Direct3D - it would just not be able to do very much according to the card capabilities. In Di ...Show All
