• Game Technologies: DirectX, XNA, XACT, etc. Sample Framework

  I've been looking over the sample framework (empty project) and I can see a lot of useful things in there that would be great if I didnt have to reinvent the wheel, mostly in terms of handling input and GUI code, but... Even though the sample framework code has a lot of comments, it's still very hard to follow and feels like it's all over the place. I realise we all have different coding styles but I was wondering if anyone has some kind of ...Show All

• Windows Forms OptimizedDoubleBuffer

  I heard somewhere that by setting ControlStyle.OptimizedDoubleBuffer, you automatically have ControlStyle.UserPaint and ControlStyle.AllPaintingInWmPaint set as well. Is this true The API is unfortunate, but it is a ControlStyle which affects a minority of users. Typically, we'd suggest Control.DoubleBuffered. Marking Obsolete is akin to ripping it - we generate build warnings for every project where it's being ...Show All

• Visual Studio MSBuild Observation - Unit testing extensions

  Here's something I think the MSBuild team should consider for future versions..... Writing unit tests for custom loggers and tasks is a really serious pain. I'm writing a custom email logger that inherits from FileLogger. This will enable me to email off the contents of a build log. I've chosen to inherit from FileLogger because I don't want to write all the routines required to capture output and dump it to a file. I just want to read the log i ...Show All

• Visual Basic Using the progressbar

  This is what I am trying to do: Copy a file from my resources to the temp directory. Get the size of the file in my resources in bytes. For every byte that is copied I want to step the progressbar by 1. The part I am having troubles with is getting the size of my file. I want to get the size so I can set the progressbar's maximum property to the same value. Also, would it be a good idea to use a background worker for this Thanks. T ...Show All

• .NET Development Named Pipes in C#

  I need to pass data from one process to another.  In the "Visual C++ Version 6" world I would have used a global named pipe for this task.  I'm developing in C# and would like to know what construct there is for either creating named pipes or for a "new" technique to pass data from one process to the other. One other specific is that the process producing the information, i.e., filling the pipe, is a service created using ...Show All

• Visual Studio Team System Deployment for Test Projects in multiple solutions

  Hi -- I have been trying to figure out how to get deployment of test items working for test projects that exist in multiple solutions. It doesn't make any sense to me why Miscrosoft decided to make test deployment relative to the solution when it seems like that is something that is specific to the project... ( ) But that's neither here nor there. The possible solutions that I'm thinking of are: Have a testrunconfig file for each test ...Show All

  Hi, I am new to WWF and trying to understand in creating workflows. I was trying to build a custom workflow with Beta 2 but I cannot find the parameters attribute in the Workflow class.
