• Visual Studio Team System Unit Testing Forms - Accessing Controls

  I'm unit testing an extremely simple VB form with a button and a text field.

• Software Development for Windows Vista DVD Subtitles

  Hi, Does anyone know how to configure the MPEG-2 demux to enable subtitles to be displayed from a ripped VOB file (we have a legitimate reason for this). I have spent a long time on this and it's driving me nuts! The graph is pushed from a network receiver filter which configures the Demux in CompleteConnect(). I am using pMPEG2StreamIdMap->MapStreamId(0xBD,MPEG2_PROGRAM_ELEMENTARY_STREAM , 0x20, 0x04); And tried various combinations of media types e.g mt.majortype = MEDIATYPE_Video mt.subtype = MEDIASUBTYPE_DVD_SUBPICTURE; mt.formattype = FORMAT_MPEG2Video; ... For some media types the MPEG-2 Video d ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Where to go?

  Hello everyone, This is my first post. A week a go I didn’t know C# existed and only had heard the term “Direct X”, but never knew anything about it. 5-6 days a go I accidentally stumbled upon the 8 part C# RSS reader video tutorial (Done by learnvisualstudio.net, but hosted at Microsoft). I watched most of that and became quite interested in trying C#, so I downloaded C# express edition. Later I read a bit about DirectX, which made me really, really, really want to make a game. Since then I have been devoting about 4-6 hours a day to learn C# and DirectX.   I have learnt a lot, but I am definitely extremely new. ...Show All

• Visual Studio Team System Disposable fields should be disposed: depth of call-graph traversal

  Hi,    I am doing some research on FxCOP for a unversity project (funded for Microsoft Phoenix Research) and I had a question about the heuristics used in your call-graph traversal, for example, in the rule "Disposable fields should be disposed". As described in the text, "This rule checks to see whether a disposable type T declares a field F that is an instance of a disposable type FT . For each field F , the rule attempts to locate a call to FT.Dispose . The rule searches the methods called by T.Dispose , and one level lower (the methods called by the methods called by FT.Dispose ).". Why did you choose to lim ...Show All

• SQL Server deploy to another server

  I do not have access to VS, but I hear it can do this... how can I do it without VS I am using CREATE ASSEMBLY to load dll form my server to SQLServer on my server (Same machine). How can I load the dll to another server Do I have to write it on a directory on that server first I tried to run the command from my pc connected to the other server, and I get a "cannot find file" error. The FROM clause in CREATE ASSEMBLY can either take a path to the dll (which is what you are doing), but it can also instead of the path take the binary representation of the dll. So in your case, you can ei ...Show All

• Software Development for Windows Vista How do you make IMemberCreationService available?

  I started a new C# console application, added the System.Workflow references and a Sequential Workflow (code) item. When I tried to open the workflow to add activities and I got this error message "The service 'System.Workflow.ComponentModel.Design.IMemberCreationService' must be installed for this operation to succeed. Ensure that this service is available." Confused, I added a WorkflowConsoleApplication project in the same solution and I could see the workflow diagram and add activities. So I checked that I have all the references tha tthe WorkflowConsoleApplication has and I'm added the System.Design, Transaction and Web namespac ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Floating Point arithmetic difference between VB and C#

  I am in a bit of state at the moment, I am really surprised at what I have found, please see the two code samples below. The first is Visual Basic and yields a result of: 100040624.0 the second C# and yields a result of: 100040629.0, which is correct. This error is causing my Line Circle intersection function to fail!! Oh my God have just spent the last two years writing my app in VB and now have to convert to C#.

• Visual C++ "Waiting for an internal operation... please contact Microsoft"
