• .NET Development Class diagram architecture question

  Is it a standard practice to have an abstract parent class for the sole purpose of grouping a particular set of classes There is no methods, members or anything in the class. Here's an example of what I'm trying to ask: Say I have Superclass called RobotPart, and a class derived from RobotPart called Physical. Both of these classes have their own properties and methods. I was wondering if it was conventional to have two derived classes of Physical called Structural and Sensor, neither of which have any properties, methods, members or anything, other than a constructor that passes variables back up to Physical. Of course these classes would be abstract, and would not allow instantiation. Sweeps78 wrote: ...Show All

• Software Development for Windows Vista XPS Viewer not printing with XPS DrvDocumentEvent changes

  Hi , We are developing a monolithic XPS Driver. We are facing a major issue with printing from XPS viewer. We are extracted the print ticket from DOCUMENTEVENT_XPS_ADDFIXEDDOCUMENTSEQUENCEPRINTTICKETPRE and converted it to XMLDOMDOCUMENT. We did the necessary changes in the printticket, wrote it back to pvOut, but in datain.xps,Job_PT.xml is not proper.It comes as Job _PT.xml\[0].piece, and Job_PT.xml\[1].last.piece. We also found that there is a BOM of 3 bytes for UTF-8 encoding in memory pointed by pvIn. Is this the reason for the corrupted job_pt How can we handle this encoding issue Could someone please help us with this problem Thanks. Naomi. Job_PT.xml\[0].piece, and Job_PT ...Show All

• Visual Studio Team System MSBuild Project type vs TFS Project type

  I'm working on some code where I need to edit the TFSBuild.proj file, what is the best way to do this Right now I'm XmlSerializing the Microsoft.TeamFoundation.Build.Common.Project and manually doing some XmlDocument reading after the serialization (it's unable to successfully serialize all the information). Then I discovered the Microsoft.Build.BuildEngine.Project which seems to have better methods for Load and Save of project files. After some testing, I've been unable to edit specific properties in file using the MSBuild Project. Here is the code I'm using: Engine engine = new Engine ( Environment .CurrentDirectory); Project project = new Project (engine); project.Load( @"C:\Source\MyProject\TeamBuil ...Show All

• Visual C++ Managed code compilation

  I know Native C++ makes a more resource efficent program than C#.NET or VB.NET; I also am pretty sure it makes a more efficent code than Managed C++ (correct me if I'm wrong) What I would like to know is if functionally equivalant managed C++ code is more efficent than C# code Thanks in advance. another question: if you wanted to make a GUI in C#, but behind the scences you had some heavy number crunching to do, resource-wise, would it be worth it to make a external native C++ dll to do the crunching, that you refrenced from the C# GUI exe ...Show All

• Visual Studio The Class View Tool Window

  Hello, please can someone help me out. I want to extend the class view tool window however it isn't a UIHierarchy type and it isn't part of DTE2.ToolWindows collection. Using GetToolWindow("Class View") method raises an exception (and I think it's because UIHierarchy is for tool windows with a tree view only). I'm (still) new to this. Hi Derek, You need to mention how/what you want to extend on the classview. Do you need to add additional elements to the classview, or are you just adding a menu item to it's context menu For the former, you'll need to a custom library implementation. The IronPython language service package has an example of how to do this. The interfaces you'll want to read up on include IVsSimp ...Show All

• Visual Basic work surface for custom app with Visual Studio like tabs/floating/dockable/auto hide features.

  Is there a way to achieve the Visual Studio work surface using Visual Studio 2005 I just realized that the application I am porting from vb6 would be well served by that model. The main worksurface would be a tabstrip control with 6 tabs for 6 different aspects of the application. On the right (or left depending on what side the user wants to dock it) would be the properties/settings that would have a variable number of tabs dependent on which tab is selected on the main work surface. As Solution Explorer and Property windows behave in Visual Studio. Window Position (Floating/Dockable/Auto Hide, etc. Thank you for any ideas ! -greg You bet! :) It's a finicky beast.

• Visual Studio Express Editions Random numbers

  I want that some variables have a random number. I used that code: var1 = Int(Rnd * 25) var2 = Int(Rnd * 25) Var3 = Int(Rnd * 25) But I'v got still a problem. The variables haven't a real random number. When I start my program then are var1, var2 en var3 = 17,14,13. Now there isn't a problem. It looks like it are random numbers. But when I quit the program and I restart it. var1, var2 and var3 are again 17,14 and 13!!! Is there a command that give me each time other values. So real random In a nutshell, here's how to do it: randomize() var1 = Int(Rnd * 25) var2 = Int(Rnd * 25) Var3 = Int(Rnd * 25) ...Show All
