  First XNA game...done!  It's an old school missile commander clone (only its CommandeEr, like pirates...ARRRR!!!).  I spent extra time to maintain the original "cutting edge" graphics to make it a true classic.  Check it out...

• Visual Studio Project Subtype

  I have already created a new Project Type to be integrated into the VS Solution Explorer. and it is working well The VS Package for the Project I have developed is in unmanaged code using COM. Would it be possible to extend a VC# or VB project with the functionality I have acheived with the new Project type I have created. I have read about Project subtypes. My question is if I enable my project package to support IVsAggregatableProject and IVsAggregatableProjectFactory, can I aggregate it with a VC# or a VB project. Can all the commands and functionality from my project be integrated. Hi Geogy, In theory you should be able to convert your custom project type to aggregate either the C# or V ...Show All

• Visual Studio 2008 (Pre-release) Brush Invert

  Is there an equivalent in WPF to BitBlt with DSTINVERT as the last argument (This inverts whatever is behind the brush) Cheers More details on my previous post: I'd like to display a "selection" rectangle. The rectangle should invert the colors of whatever is behind it. I noticed that Microsoft Word does this when you select a piece of text but the WPF TextBox does not. Does it mean it's not possible in WPF ...Show All

• Visual Studio Toolbox not displaying items!

  Hello, I'm developing a smart device application using C# with Visual Studio .Net 2005 professional ed. I'm having a strange problem where the toolbox stopped to display all the items!! I'm unable to add any control to my forms now. I think this happened after I tried to add a custom control of mine to the toolbox. I tried reseting the toolbar, uninstall and install, same problem. Note that when I open other projects which are NOT smart device applications, the toolbox is fine. Please help, I cant continue working! mnar, Sounds like you got the toolbox in a strange state. You can try resetting the toolbox cache by doing the following: Close all instances of Visual Studio ...Show All

• Architecture Data Provider Design Pattern

  i am currently developing a data access layer. my aim is to separate the entities from their data access logic. this way i will be able to work with different data sources with the minimum of fuss. i am trying to implement a kind of provider pattern in order to achieve this aim. please let me explain with a simple example. let's say i have a class called Client which has fields and properties for name and department. my proposed solution is to make my entity a simple object with just these fields and properties (CDO object so good for serialization over web service) then i can have an external Provider class which fills my entity like this: ClientProviderSqlServer ... while (rdr.Read) { client = new Client(); if (r ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Beta 1 & Beta 2 Together

  Hi - I've been distributing a small compiled demo of an XNA game and I've run into the problem that if the end-user has both beta 1 redist & beta 2 redist installed, even though I'm referencing the beta 2 DLLs, the program automatically references (or does something) with the beta 1 DLLs. Is this unsolvable, or is there any way to fix this Thanks in advance... Fair enough - thanks for the answer. Weird that it automatically references the previous version, but oh well it's not like most people will have have 2 versions installed (end-users that is). ...Show All

• Visual Studio Team System Migrating WorkItems to a new project.

  Okay so we've completed our first project using TFS. I'll have some comments regarding the experience on my blog later. I want to branch the code into a new project and migrate the work items...or maybe somehow branch the workitems as well. The trunk will be used for the production version of the system, while the branch will be v.next. Some of the work with v.next will fix the code from prod and we will want to merge it back into prod. For the most parts the changes to prod will be specific to prod and we don't want new prod code going into v.Next. There are definitely some work items/scenarios et. al that I'd like to bring over to the new project rather than re-entering them. I know that exporting to excel and importing to the n ...Show All

• Visual C# Urgent........Inheritance.

  Hi, I want to design a base class in such a way using that i can define only one derived class. if i define another class it should give an error. There aren't any really good answers to that one. Although, I've always thought it would be nice to have something that allowed you to limit the derived classes of a base class. You could, for instance, limit the derivations from XmlNode to the set of valid XmlNode types. The closest thing I have seen in any language, though, is Java's enumerations. To answer your question, if the base class and derived class exist in the same DLL, you could always make the base class's constructor have internal visibility. Can you tell us more about what you're trying to ...Show All
