• Visual Studio Team System Team Foundation Server vs SubVersion

  Hi, Did any one has done comprehensive report comparing Team Foundation Server vs SubVersion vs VSS The comparison will be toward business decision. - Cost analysis. How much saving if using TFS compare to others - Efficiency & Productivity - Quality Assurance. - etc Thanks, John > Sourceforge is using SVN too - should they use TFS in future Errm. No. If you wanted a Sourceforge like site that was using TFS, then check out the excellent CodePlex site ( http://www.codeplex.com ). You are correct that you need a Microsoft platform to run TFS on. For the kind of organizations that TFS is aimed at, this is not a problem. Considering how new TFS is, the adoption has been staggeringly ...Show All

  Hi, I have been asked to report the results of a query in "Boxes and Links/Arrows" - as shown schematic below. Any ideas how to go about it - in a simple and tested way I would need to be able to print the "ouput" as well. Of course the Number of Suppliers would be dynamic.

• SQL Server Sanity Check/Question About Idea

  OK can someone look at this idea and tell me if it sounds like it would be work and be a good way to do things On our Virtual Server machine I have 4 Server's setup. All Running Windows 2003 Standard. Server1 - SQL Server 2005 Standard Server2 - SQL Server 2005 Standard Server3 - SQL Server 2005 Express Server4 - SQL Server 2005 Express Now I would have Server1 & Server2 in a DB Mirror Mode. With Server3 being the witness. When Server1 Fails Server3 would tell Server2 to become primary. Then when Server1 comes back it gets updates from Server2 and vice versa if Server2 fails. Now Server4 I was hoping to remove some of the processing that is done (currently via DTS in SQL 2000). This scheduled jobs will get the upda ...Show All

• Software Development for Windows Vista Problems playing video that uses the Indeo 5 codec

  I have been testing my company's software application on Windows Vista to check compatibility. The software product makes use of video clips (avi files) that have been encoded using the Indeo 5 codec. These no longer play in Windows Vista! Even when trying to play the avi file in Windows Media Player, it fails. We have checked for the existence of the codec (a file IR50_32.dll in the Windows System32 folder) and it is there but appears not to be registered as part of the Windows Vista installation. The only way we cna register it is by running regsvr32 against the file but using the "Run as Administrator" option. This is not very desirable to end users so is there a way we can do this in our Windows Installer package (tr ...Show All

• Visual C# how to return null from a constructor

  say, i a m trying to do something like: class something something(streamreader){ if (wrong format or end of file) caller receives null as result else build object from what has been read in file } i tried 'return null', but it says it can not do that since a constructor is 'void', so i can not place a return sentence. i'm not sure something like this.dispose would retunr a null, since the 'dispose' may be asynchronous (or something) i have the next alternative class something blah blah somehting(string) (build object from string, check if string==null or wrong format before calling) static bool checkformat(string) check to see if string is adecuate to build somet ...Show All

• Visual Studio Debugger opens wrong files

  I am running a relatively large unmanaged VC++ solution (~110 projects) in Visual Studio 2005 which builds a handful of dependant libraries, unit tests, and a couple sample executables. As one might imagine, this solution contains a number of files in different projects which share the same name ("test.cpp", for instance). When stepping though code, the debugger has the tendancy to bring up the wrong file. I can set a break point in a given file which is respected by the debugger, but it then proceeds to follow the execution path, correctly following line numbers but in the wrong source file. This behavior suggests to me that maybe the system is using some kind of hash based on file name which has some-how fallen out of sync with the files ...Show All

• Visual Basic How can I close all open database connections?

  Hello, I need to loop through all connections to the database I am using in my app (an .mdf file) and close and dispose of them all prior to exiting my application. Could someone please show me how to do this I am primarily using table adapters to access my DB. Thanks. In the closing function of your application is where you would want to initialize it...but that's about all I can help with there :\ Use a For Next method though and set Count = to the number of connections open. Then cycle through them and try the .Close() method I guess I've never dealt with closing of connections, so that's about all I can provide you. ...Show All

• .NET Development Dynamically instantiating a class at runtime using reflection

  Assume that I have two string variables as follows: string ClassName = "Currency"; string PropertyName = "ISOCode"; Further assume that the Currency class is defined in another Visual Studio project. The references and using statements are already programmed. How can I instantiate the class and access the property dynamically at runtime Please keep in mind that I can't do the following: Currency MyCurrency; I don't know at development time which of about 1,000 classes I'm going to want to instantiate. I need to get the class to instantiate from the value included in the string variable. Thanks for your help!!!!!!!!!!!!!!!!!!!!!!!! Take a look at this code. I am sor ...Show All

• Audio and Video Development Is there a way to do a frame grab of a movie and store it as a jpg or png in the persistent storage ?

  Hi All, I was wondering if there is a way to do a frame grab of a particular scene while watching the movie and store that frame as a png or jpg in the persistent storage of the player Let's say I define a function for key "A" on the remote which does this when pressed. Any pointers would be appreciated. Thanks All resources that you reference in markup MUST be in the filecache. Although you have copied it to pstore for permanent use, you must copy it back to filecache (or rather, just use the original one in filecache) when you reference it in markup. ...Show All

• Windows Forms A Simple GUI Question

  I have an application which requires saving data. But user do not need to open a file or save a file. But I need a save and exit. Do I still have a File Menu Intuitively, File menu is for saving files. What does the guideline say Thanks much There is no 'set' way to create a method to save a file and exit your application. You can do this however you want. From what you explained it sounds like you want to save the file when the program exits. If so then you can use your Forms FormClosing Event to save the file.

• SQL Server Error in Scheduling SSIS Package

  Hi, When I am trying to schedule the SSIS package and start the job, I am getting the following error. It is not executing properly. "The job failed. The Job was invoked by User prakash.srinivasan. The last step to run was step 1 (TestSchStep1)." Pls provide some solution to this. Thanks in advance. Regards, Prakash Srinivasan. One thing you might want to check is to see if the PC where you developed the application is on the same version as the server where you are running the package. I had this same problem while I was developing on SQL 2005 SP1 and deploying the package to run on SQL 2005. Once I installed SP1 on the server, the packages started running successfully again ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Color based collision detection?

  Sorry if this question is laughable, I'm new to this stuff. Is there any way to do collision detection based on color. For example, a plane sprite intersects a segment of screen that is green and triggers an event independent of vector intersection math. You don't want to try something like that. Every model or sprite you use should have one or more bounds objects that you can use for collision detection. There are some collision comparison operations already built into the xna primitives. BoundingSphere, BoundingBox, Ray, Plane and the others all have the ability to compare against most of the other shapes. "Screen space" is only for rendering and getting mouse input coordinates.

• Software Development for Windows Vista /analyze + Windows Vista SDK + VSTS2005 = crash :(

  First time poster long time reader... I have been using VSTS2005 for sometime, main reason for upgrade was to use the /analyze compiler option for unmanaged c and c++. Two days ago I downloaded the Windows Vista SDK, installed it and clicked on 'All Programs->Microsoft Windows SDK->Visual Studio Registration->Register Windows SDK Directories with Visual Studio 2005'. Since then compiling my project with /analyze causes VSTS2005 to crash. I would rather not uninstall the SDK as the compiler seems to be finding a lot more issues with my code, before it crashes! Any suggestions what I can do Thanks in advance. ...Show All
