• Game Technologies: DirectX, XNA, XACT, etc. How to "publish" my own IGameService

  I've read Mitch Walkers article on the IGraphicsDeviceService and I understood it for the most part. Where I'm a little unclear is on the actual mechanics of creating my own GameService. The article says that the Graphics Component "publishes" an interface as a service. Does this mean the GameComponent internally actually creates a concrete instance of IGameDeviceServices and calls Game.AddService Here is an example: Lets say I'm creating a 2D Physics component that relies on an undelying "Physics" object (this object does all the simulation for rigid bodies). I want to allow others to either use my PhysicsComponent or create there own component that would could still interact with any other higher level physic ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Comparison of Techniques?

  Hi. I am new to DirectX and XNA, although I have a programming background in asm, c, and vba. After delving into the DirectX SDK and the XNA docs, I could not easily find an answer to my question, namely a comparison between different ways of doing the same job. My plan is to create a 'tile' based computer game along the lines of the old Avalon Hills board games. This means that it will use hexagonal tiles, terrain, and unit icons. The map will be large and scrollable, as well as enabled with the ability to rapidly zoom the map in and out. Units and terrain will be 2D, with no overlapping into adjacent hexes. The borders of each hex will be visable. As in general programming, there seems to be many ways to go about accomplishin ...Show All

• Windows Forms fire TextChanged for a ComboBox

  I've been reading the related posts and playing around with my ComboBox and its TextChanged event since this morning,but still stuck. Here is my issue: ------------ Instead of SelectedIndexChanged and SelectedValueChanged, I use TextChanged event to detect the real change of a ComboBox. It cannot be edited, so I set the dropdownstyle as DropDownList. I've checked that the TextChanged has been registered. But when I run the application and select other option from this combobox, this event still cannot be fired. To solve this problem, what else can I check Or do I miss anything ------------ Appreciate your time.Thanks!   nobugz wrote: For that matter, what's wrong wit ...Show All

• Windows Forms Activating the [Caps Lock] Balloon

  If you have the password character set for a textbox, and the user presses the Caps Lock key while that textbox has the focus, a notification balloon is automatically displayed, alerting the user that Caps Lock is on. My question is: How to fire that event programatically (ie, Caps Lock is already on when focus is obtained). Is there a message I can send to the textbox The easiest way is to use the ES_PASSWORD flag on a TextBoxs Style property such as this implementation stolen from here : public class PasswordTextBox : TextBox { private const int ES_PASSWORD = 32; public PasswordTextBox() { } protected override CreateParams CreateParams { [SecurityPermission(Secur ...Show All

• Visual Studio Express Editions problems with Configuration manager

• Software Development for Windows Vista Fixed hash algorithm in CertEnroll library

  Hello! The problem is fixed hash algorithm (SHA1) used in CertEnroll library. That's why  we can't create a certificate request using our Cryptographic Provider (CSP), that implements Russian Crypto-algorithms but not SHA1. X509Enrollment.IX509CertificateRequestPkcs10 interface has HashAlgorithm property that is used for signing PKCS#10. But after creating PKCS#10 CertEnroll creates "dummy-certificate" for the "Request" store (like XEnroll does). And it tries to sign this certificate with fixed in CertEnroll::CX509SignatureInformation::SetDefaultValues SHA1. We think that it is more correct to use the same hash algorithm as for signing PKCS#10. And several  comments for "Certificate Enrollment" wizard from "Certificates" snap-in: ...Show All

• Visual C# Adding reference to project

  Hi, i tried adding a reference with extension 'dll' to my project but this error keeps popping up:This is not a valid assembly or COM component.Only assemblies with extension 'dll' or COM can be referenced. Help will be greatly appreciated! Right, only a COM dll or a .Net assembly can be added to references. Might be you are trying to add some native dll so you are getting that error. You can use dll with DllImport and use function names which you want to call. See Cetin's example! Usre your own name instead of user32.dll and use function name that is avaialble in that dll with correct paramater then you can call that function from anywhere in your code! I hope this will help!

• Visual Basic Trouble w/ MS Direct Speech Recognition

  Hi I created a small windows application w/ speech recognition using MS Direct Speech Recognition (ACTIVELISTENPROJECTLib.dll) It works great on my machine (one that I created the windows application w/ VB.NET 2005) but it doesn't work on any other machine.

• SQL Server Parametrization of xsd:boolean RDL element

• Visual C# Enum DataBinding (SelectedValue)

  Why is it that the Binding method ....Binding ( propertyname ,bs, datamember .... not working ..... datamember : of type short propertyname: SelectedValue I am using : combox.DataSource= Enum .GetValues( typeof (xxxtype )); where xxxtype is of enum type. Regards Alu Hi , Sorry for the unclear explanation. Guess I may have solved the problem. I found that enumtype.member need to be casted with the type define in the enumeration before binding can be used like this: public enum xxx{ type1 = 1, type2 = 2 } I used a class to wrap around this enum and use a List to keep the object before binding to a combo box. like this : list.add(new classxxx(parm1,parm2....))
