• Windows Search Technologies How to kill a process that is not even listed in task manager?

  Hi, I'm having a problem to kill a process. For your information, the process is not even listed in the task manager. I would like to delete that particular file, but it seems like there's a process of software currently associated with that file.

• Visual Studio Team System Where is the reference about CommonStructureService.asmx?

  Hello! I'm interested about using the method CreateProject() available under the CommonStructure web service but I can't find any reference about it. Can anyone help me about that Regards, Max As I have read, the recommendation from Microsoft is NOT using the webservices for integration, and use the object model instead of the web services, this object model, communicates also via this webservices, but you will find more documention, and it will be easier to use than this web services. ...Show All

• Visual Basic Radio Check Options in Menu Strip?

My question is.... Does the 2005 version support the radio check boxes as it did in 2003 ...Show All

• SQL Server Multithreaded run of SSIS packages

  Is it safe to run several SSIS packages in parallel in a multithreaded application The package objects are not accessed from multiple threads: every thread is handling its own package (see below). void task_inside_thread() { System::String ^s = "..."; Microsoft::SqlServer::Dts::Runtime::Package p; p.LoadFromXML(s, nullptr); // callback handler MyEventsClass ^ eventsClass = gcnew MyEventsClass(); DTSExecResult result = p.Execute(nullptr, nullptr, eventsClass, nullptr, nullptr); return; } Is there any relevant documentation with respect to this issue Thanks, Bogdan I wor ...Show All

• SQL Server Assigning the value of variables in a Subpackage

  Hi, I have a parent SSIS package that executes various subpackages. Each of the subpackages contain variables that are required for their successful execution, e.g. one has a variable of datetime datatype and a variable of varchar datatype. This date will essentially change with every running of the package as it specifies the date that additional data has been added to the back-end SQL Server 2005 database. I can't find anything in the expressions of the Execute Package Task that would allow me to pass these variables into the package. Can anyone advise Thanks, Paul Look at the documentat ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Collision Response Flaws

  Hello, I'm trying to make a spaceships shooting game with view from the top. Anyway, I'm using spheres as bounding volumes, so my collision detection consists just from whether the distance between spheres' center is smaller than their radiuses together. As a collision response algorithm I used one from this webpage: http://www.gamasutra.com/features/20020118/vandenhuevel_03.htm However, there happens to be some incorrect reactions, specifically that there is no bounce, while they are overlapping. This happens mostly when one object is almost standing still.Moreover I am omitting Z-axis, because all of the objects are on the same - ...Show All

• .NET Development System.IO.Compression not as good as compressed folder

  I'm getting much better compression when I make a compressed folder (Windows XP) than I am using DeflateStream or GZipStream.  I thought these were the same algorithms used in PKZIP and for compressing folders.  Why such bad compression DeflateStream: 3544Kb -> 1261Kb GZipStream: 3544Kb -> 1261Kb Windows XP: 3544Kb -> 804Kb So how can I get the same compression ratio as Windows XP Thanks, Jeremy The problem does not exist in NetFX 3.0 because it didn't exist in version 2.0 either. The DeflateStream object applies the Deflate algorithm to data on a stream - the d ...Show All
