• SQL Server long running transaction blocking queue

  Hello, I seem to be misunderstanding the way transactions work with service broker queues. We have developed and deployed a service broker application that 5 queues and a windows service for each queue on multiple servers (3 currently). Due to a last minute issue, we had to not use transactions when the services executed a recieve and I am not updating the code base to use transactions and am running into blocking issues. One of the services runs for 90 seconds (spooling to the printer) and all of the servers block on the receive operation for this queue. I thought that if I was receving messages from a single conversation, other receives against this queue would not block. Thanks, Jim Stallings ...Show All

• Visual Studio 2008 (Pre-release) I can't make P2P to work

  I read "Harness The Power Of P2P Communication In Windows Vista And WCF" ( http://msdn.microsoft.com/msdnmag/issues/06/10/PeerToPeer/ ) and downloaded example from this article, but it doesn't work for me. I was able to compile it, but when I put app on 2 computers and tried to share image nothing is happening. (This app is using certificate and I was not sure where to get it. So I just generate one and installed it on both machines). Is anybody else tried to use code sample from this article If not are there any other code samples with p2p in Vista I met the same problem, here is my resolution: 1: Can not compile, because the .net Framework version is different from that sample. ...Show All

• Visual Studio Team System Workspaces opt-in rather than opt-out

  Hi Guys, we have a number of different solutions inside a single TFS Project. We have create a number of team builds designed to build single solutions. Initially we had a performance problem building a solution as the entire source code repository was being retrieved before doing a build. To correct this we have cloaked unnecessary source paths using the workspace.xml (opt-out). While this works the problem going forward is that new solutions are automatically included which means that all of the team builds need to be updated to exclude the new solutions. Is there a way to exclude all solutions and only opt-in Wildcards are definitely forbidden, is there any other way to achieve this Another possible option I have explored is to map to ...Show All

• Windows Forms Help in implementation of a magnifying glass

  I have an image viewer application which I want to apply a magnifying glass effect on certain area of the image. The problem I've run into is that when I slowly dragged the magnifying glass across (when left mouse down) the magnifying glass window didn't move smoothly. I believe it has something to do with drawing the graphics of the original image on the background. May someone please help me solve this issue Thanks. Okay, so what's "this.image" Sounds like a bitmap. magnifyGlass_Paint() will be very slow if that bitmap is not in PixelFormat32PArgb format and this.image gets large. If you get this image from a resource, copy it into a bitmap with that format and use that bitmap for all your pa ...Show All

• SQL Server Changing Default Rendering Method of Reports

  Ladies and Gents, I have a question with regards to the default rendering extensions for reports. I am using RS 2005 with SP1. I am accessing a report as follows: http://<ReportServerName>/Reportserver /<Folder>/<Report Name> Sample: http://TestServer/Reportserver /Special Reports/Dealer Report This displays the parameter bar and the view report button. When pressing the view report button, the report is automatically rendered into HTML 4.0. Is there a way to use the existing parameter bar and automatically render the report to a different extension (such as PDF) when the parameters are entered and the View Report Button is pressed. Thank You for any advice you can give, Raph ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Post-Processing glow shader

  I'm trying to get the Glow shader technique discussed in a Gamasutra article (http://www.gamasutra.com/features/20040526/james_pfv.htm) implemented in my XNA project but am struggling with certain aspects of it. The blur of the scene takes place in two separate passes, one for each axis. So when you do the horizontal blur pass, you pass it your scene which you've rendered to a RenderTarget2D. Then for the vertical blur pass which follows, you have to pass it the resulting texture from the previous pass. This is where I don't really understand anymore... what is the proper way to set this up so that you can extract the results of the first pass and give it to the second pass when you already have an Effect activated ...Show All

• Visual Studio @err,hr or its equivalent in 2005

  In older versions of Visual Studio (6 i know for sure , 7 i think) you could put the string @ERR in to a watch window to see the last error (as returned by the function) and you could put ,hr on the end of any HRESULT to get the string equivalent of the error, This was terribly handy. Is there any equivalent in the newerversions of vs Thanks, Eric- ERR, hr is so useful, it's unfortunate that it's not documented in the Pseudovariables page of the Visual Studio Debugger documentation (or anywhere else, as far as I can find). It was very nicely documented in the "Viewing the Last Error Code for the Current Thread" page of the VS6 documentation. It seems like an unfortunate ...Show All

• Windows Forms Determine if List is displayed for ComboBox

  I have a situtation where I need to not let the mouse roller change a value in a drop down list. I was able to accomplish this by trapping the 'MouseRoller' event and canceling it for a ComboBox. However, now my users want the mouse roller to be enabled if the list is displayed for a ComboBox so they can scroll through the items. So I was wondering if there is a way to know if the list is being displayed for a ComboBox editor I am hoping to use it in the 'MouseRoller' event and not cancel the event if the list is in fact being displayed. Thanks in advance. Thanks for the reply...Yes, logically that is what I am looking for, but there is no such property 'droppedown' for combo that can give me what I am loo ...Show All
