  Hello this questions is for people who creates new technologies so fast and also for people responsible for creating the certification tracks.

• Visual Studio 2008 (Pre-release) Indexed Property with Nested Binding

  I'm very new to WPF, but already it seems like I'm trying to do something difficult already! I have a list of "Person" objects. A Person class has a property called "Infos". This is of type "InfoList". The InfoList has an indexer property, indexed by a "Category" object. public class InfoList { public string this [ Category category] { get... } } Basically, this lets me do stuff like: Console.WriteLine(aPerson.Infos[categories[2]]); In my UI I have a listbox of person objects and a tabcontrol of categories. On each tab page I'm trying to display the Info for the selected person and current category. I've tried using the following in my tab control's ContentTemplate: < Te ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Contain the mouse inside the game window

  Hey Everyone, The subject pretty much says it all. Is there a way to keep the mouse contained inside the game window so the gamer can't scroll outside its bounds thanks Here's code that does it from my project. It deals with several cases: 1) windowed mode 2) making sure to not steal the mouse when not in the foreground #if !XBOX360 if (IsActive) { MouseState ms = Mouse.GetState(); int cx = Window.ClientBounds.Width / 2; int cy = Window.ClientBounds.Height / 2; if (ms.X != cx) { simInput_.RightX = Clamp(32 * (ms.X - cx) / (float)cx, -1, 1); } if (ms.Y != cy) { simInput_.RightY = Clamp(32 * (ms.Y - cy) / (float)cy, -1, 1); } ...Show All

• Windows Live Developer Forums It finally worked

  We are getting this error since saturday night: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: signature check failed Our client is linux/axis. Anybody else seeing that I'm also having trouble with the suggested steps. It won't work unless I import the final certificate as well. Furthermore, assuming you have already imported msft_ia_prod and msft_ssa_prod into cacerts , then passing -trustcacerts (*) to keytool when importing the final certificate should avoid the trust confirmation question. However, it still asks you for confirmation, as it somehow doesn't recognize the link betwen the fin ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. What's difference between Express and Professional?

  I've installed the Express edition beta 1, but I have interesting to the Professional edition. I thought the Professional edition should have more classes than Express edition, but I've never seen any documentation to compare the class library of each edition. Could you tell me the differences of them, particularly about class library Or I'd be happy if I could find the reference manual of XNA Game Studio Professional on the net. Thanks, Hayashida Well, I don't plan on writing 360 games, so the devkit stuff wouldn't matter to me. The ability to use it with something besides C# Express without having shell out lots of money would be nice. I'm sure there are a lot of non-professional developers that us ...Show All

• Visual Basic History keeping solution/Defining data from a table in VB

  What I'm trying to do is move the data of one record from one table to the next and drop off at the last table (keeping a history so to say). History 0 => History 1 => History 2 => ... => History 14 Each Record has 40-50 datafields per table so as you can see it is too big to be stored in one query/table. The solution I have thought of is to have queries spanning two consecutive tables and shuffling it along using a Visual Basic application. Doing so, I've encountered difficulty in defining the data from tables usually getting the error message "External name not defined". What is the correct syntax to define the data For example one of the tables is called "History 0" and one of the fields in it ...Show All
