• Game Technologies: DirectX, XNA, XACT, etc. simple projectile motion physics??

  im pretty new to gamedev, so simulating physics is new to me too. i know the projectile motion formulas, im just having trouble applying them. is there any "tutorial" on projectile motion physics for XNA basically, someone suggested to do "scorched earth". im trying to get the hang of just some simple projectile before i apply it to a game. i know i should basically have to just enter the initial velocity vector and the angle. then have it passed to a function that gets the initial x velocity, and initial y velocity. also, im assuming that whatever i get for y-velocity should be negative as "up" is negative in the XNA graphics. then, after each update, it should find the current change in position for x and ...Show All

• Windows Forms application manifest errors

  I'm getting the following error message at on one of my customer’s pc when installing an update to a deployment. All of my other customer’s are working fine. Has anyone experienced this issues or has seen this message "Reference in the deployment does not match the identity defined in the application manifest" Here's Microsoft’s explanation. http://msdn2.microsoft.com/en-us/ms229001.aspx I also saw somewhere in the past, that you needed to deleted the local internet cache on the client’s pc which was done. I've also uninstalled the click once app using add/remove programs. So I guess I'm not sure what to do. Here's the actual error: Reference in the deployment does not match the identity defined in the application ...Show All

• Windows Forms Can I unsign a ClickOnce manifest

  Without breaking the projects and having to reinstall the app. David, My certificate (VS test certificate) will expire soon and I am too looking to avoid uninstalling and reinstalling the application. When I update an application I simply replace a new *.exe for the old one. Will this cause the application to not run and do I have to create a new test certificate and re-install the whole application Will the application stop running after the certificate expires even if I don't do an update Thanks, Jerry ...Show All

• Visual Studio 2008 (Pre-release) Required or optional fields.

  I have a data contract that looks like: private string _BasketIDField; [ DataMember (IsRequired= true )] public string BasketID { get { return this ._BasketIDField; } set { this ._BasketIDField = value ; } } But when I generated the proxy for the client I see: [System.Runtime.Serialization. OptionalFieldAttribute ()] private string BasketIDField; [System.Runtime.Serialization.

One other indication is that I get an exception ...Show All

• .NET Development Naming rules for a base namespace in a Class Library

  I am building a Class Library for use with a number of applications within my company. I am debating how to name my base namespace, i.e. the one that contains all the base/fundamental classes, enumerations, event handlers, etc. Right now I have named it [My Company].System Is that a good idea One thing I don't like about it is that it duplicates the System namespace. According to Microsoft guidelines it should be Company.Technology.ApplicationName. Also check out the following book http://www.amazon.com/Framework-Design-Guidelines-Conventions-Development/dp/0321246756 by Brad Abrams & Krzysztof Cwalina.

• .NET Development Graphics object for printing

  Hi, I am trying to calculate the number of pages in a print document in order to update the PrinterSettings.FromPage and PrinterSettings.ToPage before the PrintDialog is opened. I know how to calculate the number of pages, but I need a graphics object. The problem is that I don't have a reference to a graphics object until the PrintDocument's PrintPage event is fired (which occurs after the PrintDialog is closed). Which graphics object should I use Any help would be appreciated. Lee I wrote a rendering engine that operates in three modes. In draw mode is draws pages on the screen. In paint mode it paints to a graphics object. In prepare mode it just returns a collection of page objects that desc ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. "The project type is not supported by this installation." with Beta 2

  I've installed VC# Express (side-by-side with my VS Std) and then XNA Game Studio Express Beta 2. When I start a new project I can see no XNA templates, though. When I try to open an existing example (built with beta 2) I get the error message "The project type is not supported by this installation." I've not had XGS beta 1 on this machine. I've tried uninstalling both XGS and VCS and reinstalling to no avail. Please help.

• Commerce Server Commerce Server 2007 Shipping Options

  Hello, I am trying to figure out how to get shipping rates including the price and MaxLimit (the data from ShippingRates table). I can get the shipping method data by using the ShippingMethodHelper.GetShippingMethod() method, but I can not figure out to get the child data from ShippingRates table. Please help. Thank you, Dmitry Hi Dmitry, You cannot get the ShippingRates from the runtime side - this information is pulled from the DB when the pipelines are run. Instead you can use the Management APIs to get this info for e.g. the ShippingMethods property for all the active ShippingMethods in the system: http://msdn.microsoft.com/library/default.asp url=/library/en-us/sdkmref/html/P_Microsoft_CommerceServer_Orders_ ...Show All

• Windows Forms Hosting the designer

  I don't know whether hosting the Windows Forms Designer is the best solution for me, but before I dive into the topic more deeply, I would like to get an overview of what is possible. The program I develop should be able to switch to some kind of design mode, so that specific controls (some buttons, a listbox) can be resized or moved around on the form by the user (The form itself should not be editable). I would like to know whether this is possible to implement by hosting the Windows Forms Designer. Another approach would be to implement some of the behaviour myself, although I'm not quite sure about the best way. Some thoughts: I could derive from the standard button and provide a design-time button that enables the editing functionalit ...Show All
