• Visual Studio 2008 (Pre-release) Problem using event of Timer to set text on TextBlock

  Hey, I'm trying to set the Text property on a TextBlock when the Elapsed event is fired on a Timer object. But I'm getting an InvalidOperationException with the follow explanation "The calling thread cannot access this object because a different thread owns it." This is the line of code that fails, it sits inside the timer_Elapsed() method textBlock1.Text = node.SelectSingleNode( "description" ).InnerText.ToString(); I've also tried moving it outside in a service method, but no luck. does textBlock1 need to be in a specific scope or something If yes how do i managed that when the <TextBlock> element is pure XAML     Except using Dispatcher.Begin ...Show All

• Architecture Live Communications Server (LCS) & IM

  I am trying to understand the model of an IM system. I understand that LCS provides Initiation, Control and Termination of IM sessions (including security). What I do not understand is the message path once the session is initiated. Do messages flow thru the server or is a peer-to-peer connection established between the session parties Any other descriptions or information sources for the IM model are requested. The info that I have found on the MS site relates more to deployment than the model. Thanks I'm not sure about how large suppliers like MS do this, but I've build one once and decided that I didn't want all the messages running through the server, simply cause this wont scale very wel ...Show All

• SQL Server Error when file is saved to PDF

  I am calling a procedure that will save a file to PDF. It runs successfully. When I go to look at the PDF, I get a message, "Acrobat reader could not open 'Doc.pdf' because it is either not a support file or because the file has been damaged." This is how I'm calling the procedure: SaveFile(Dts.Variables( "varSSRS_URL" ).Value.ToString() + " /TestReports/MyReport&rs:Command=Render&rs:Format=PDF" , "C:\" + "MyReport.pdf" ) I don't know anything about a PDF data stream. I read somewhere else on the net that 'rs:Command=Render&rs:Format=PDF' would work. This is the sample that I got and used: //Sample call SaveFile (Dts.Variab ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Method for animating rumble on CodePlex

  Hello everyone. First, thanks to everybody who is contributing to the community. You guys are awesome! I wrote some code to animate the vibration of the rumble motors. I hadn't seen this topic come up at all and after playing a really great XNA game that had really bad rumble (either fully on or fully off) I figured it wouldn't hurt to put it up. http://www.codeplex.com/acres The first release has a Windows game project demonstrating a few different rumble animations when you press the various face buttons. I'm really curious to know how people handle controller vibration in their games. Is it an afterthought Do you handle its procedurally or through predefined settings Hi, On a title we did for Xbox we used to feed audio wave f ...Show All

• Software Development for Windows Vista How do you use ResolveIpNetEntry2?

  Hi, On Vista, I want get the MAC address of an IPv6 gateway.  I noticed that there's new IPHelper APIs to do so. First I use GetAdpatersAddresses() to obtain the list of network adapters.  I then go through each FirstGatewayAddress attribute to find the IP of the gateway.  Now I have the IP and I want to use the ResolveIpNetEntry2() function to obtain the MAC for the gateway.  However, according to the MSDN entry  http://msdn2.microsoft.com/en-us/library/aa814455.aspx I need its InterfaceLuid or InterfaceIndex . So this begs the question, how do I get either of those values that belong to the gateway Thanks.   EDIT: It would also help if someone can tell me the API for neighbor soli ...Show All

• Visual Studio Why immediate windows in unavailable?

  Hi all... Curiously, in a new installation of Visual Studio 2005 I don't have Immediate Window.

• Visual Basic Drawaing a line on an Image

  Hi guys, hope you can help me out on this one :) I'm developing a small application that contains a distance measurement tool. The idea is to make it a bit like map24.com (you clik once to select a starting point, and again to select an ending point). This works fine and I can use the graphics.drawline method to draw the line. But I would like the user to see the line already after the first click (like drawing in paint). Then when you move the mouse the ending point of the line moves. If I try to do this it draws a new line every time I move the mouse because I'm creating a new instanes og the graphics on mousemove. I have trying to make one instance and use the clear method before I draw a new line, but this method requires a color an ...Show All

• Visual Studio Tools for Office Opening designer crashes VS

  Using VS 2005 and VSTO 2005.  When I create new Word Template project and double click the document.cs file VS exits leaving a version of winword.exe in memory.
