• Visual Studio 2008 (Pre-release) Virtualized panels and lots of images

  Hi! I have a question related to virtualizing panels and images. I need to present lots of images (hundreds or even thousands) in a thumbnail view - like Max is doing... I solved thumbnail generation problems, but now I hit into other issue. I am using virtualizing panel - lets say for simplicity that I am using ListView with VirtualizingStackPanel.IsVirtualizing="True". I have made my own little class that holds basic info about thumbnails and has BitmapImage property that loads thumbnail on-demand. Here is the issue... Application start and uses about 30MB RAM. If I scroll down through the whole collection of about 2000 thumbnails (usually their size is 150x112 or 112x150), the memory used by the applicatio ...Show All

• Visual C# reading a trace file

  I have a Trace Listener running in my executable and writing trace messages to a text file. At certain times I want to be able to read that trace text file from the same running executable, but it errors saying it is being used by another process. I don't want to stop the underlying Trace. What is the best way to get around this Thanks, Rick tried making the FileStream set to read and write access as well as being shared example: FileStream theFile = new FileStream("file.txt", FileMode.Append, FileAccess.ReadWrite, FileShare.ReadWrite); //write to file //read file at the same time FileStream theFile = new FileStream("file.txt", FileMode.Open, FileAccess.R ...Show All

• Visual Studio Team System Migrating to Team System from an existing environment

  I'm new to these forums, and had posted the following in the Visual Studio Team General forum. It looks like this is the better place for this question. Sorry for the cross post. I'm looking for some strategy whitepapers or documents on how an existing development organization should go about planning a migration to Team System. My development organization has a bug tracking system, we have a source control system, we have testing tools, and project management tools, and we maintain and enhance existing products built with VS2003, VS6 (C++ and VB6), and a bit of Java. We know we will be moving to VS2005 at some point, and we have new needs that our existing bug tracking and testing tools will not handle. So Team System looks compell ...Show All

• Visual Studio Team System Linking Work Items

  Can someone please point me in the direction of more info on how to link work items and tasks What I'd like to do is create a high-level task in MS Project, Publish it to TFS and assign a number of related sub tasks and then get a summary update when I Refresh back to MS Project without having all the related sub tasks in my project plan. thanks Hi, The recommended practise for working with Project and TFS integration in V1, is to create and maintain your project plan separately. Dynamic recreation of the project with the summary and subtasks laid out in Project is not yet supported. We're adding support for this in the next version of Team System. For now, you will need to refresh the subta ...Show All

• Visual Studio 2008 (Pre-release) Freezable changes in June CTP

  In the June CTP, what became of FreezableCollection.SetFreezableContextCore(bool) and Freezable.SetFreezableContext() These methods are no longer available, and I can't find anything on this topic. Have they been replaced with something new, or removed completely Thanks in advance. I think I know what's causing your problems now, and interestingly enough, it doesn't seem to have anything to do with the SetFreezableContextCore()... things. The issue has to do with the default value that is being returned for the TriggerCollection. The reason why you're getting the error message "Cannot add element to 'Triggers'; the property is null" is because the property metadata for that trigger collection is by default returning n ...Show All

• Visual Studio SourceSafe LAN Service does not work with NetBIOS/DNS aliases.

  We have a Windows Server 2003 R2 acting as SourceSafe server. The server has been setup with a normal hostname (SERVER08) and has been enabled to allow LanMan aliases. The server has been changed as described in these short articles: http://www.sanx.org/tipShow.asp index=305     or    http://www.jsifaq.com/SF/Tips/Tip.aspx id=8062 The alias is used so we can move the SourceSafe database to other servers without the clients knowing. This setup means that the server can be fully accessed in all normal procedures (RFC, HTTP, Network shares, etc) using either name. Also SourceSafe clients can connect to the server using either the  \\SERVER08\SourceSafe or \\VSS\SourceSafe UNC path. Ev ...Show All

• Software Development for Windows Vista Capturing multiple audio streams and mixing into one stream for ASF output

  What is the best way to capture multiple audio streams and mix them together into a single audio stream for passing in to the ASF mux/writer For example, reading from mic or line in and from wav mix (separately), running a DMO filter on the mic/line, then mixing with the wav mix (and performing any SRC to match the wav mix), then sending to the ASF mux/writer as a single stereo stream. I tried to set this up with GraphEdit; no luck (the AVI muxer allowed this to work, but I need to output ASF). I also tried the Solvieg ASF multiplexer: it appears to store the channels unmixed in the file; playback on a stereo system loses the extra channel. After looking at the audio filter examples, it appears that they all use 1 in and 1 out ...Show All
