• Game Technologies: DirectX, XNA, XACT, etc. XNA Game Engine: Xna5D Alpha Release!

  I have been posting here... trying to post a bit more and get involved with helping. My name is John Sedlak (hence the username), I am 20 years old and am currently taking a semester off to work and code in my spare time. I will continue being a poor college student this spring however... anyways. Here is my project so far: Xna5D! Since late September / early October I have been working on the sequel to my MDX2.0 engine, Dx5D. I have finally got the code to a state that is acceptable for some sort of a release, hence the Alpha tag. Xna5D is all 2D based code so far, although 3D is certainly planned for its future. Here is a breakdown of what is in this release and how to get it. For more information please visit http://jsedlak.org/ ...Show All

• Smart Device Development RSA Encryption

  Hello, Is it possible to encrypt a string on the pc and then decrypt it on the pda I am using the same keys in both projects. I can encrypt and decrypt on the pda.

• Visual Basic Adding up

  Hi there and first of all Merry Christmas and Seasons Greetings to you all! I am having a mental blank which is hindering my completing a project that I am working on for uni. I am developing a travel agent booking system that allows a customer to register and book themselves and multiple other people to go on holiday. The cost of the destinations are all the same however costs do vary depending on the travellers age. There are also 4 activity's that travellers can book which also have variable costs associated with them. This is all to be stored to a database (I have this bit covered) What I am asking is how would you go about making a summery screen display the selections and costs of each traveller. I have thought about using variables ...Show All

• Visual Studio 2008 (Pre-release) Creating WCF clients from Type objects

  I was wondering if there is a way to create a WCF client by passing a Type object of the interface representing the service contract. For example: [ServiceContract] public interface IFoo { [OperationContract] void SomeOperation(); } class Program { static void Main() { IFoo proxy = new ChannelFactory(typeof(IFoo)).CreateChannel(); } } I know that ChannelFactory does not have a method CreateChannel() but I was wondering if there was a way to do the same thing. Thanks, Wells Wells,   You are right, there is no constructor for dynamically creating a ChannelFactory based on the type. I had the same problem for my Workflow Adapter/Connector Pair  solution where the client proxy w ...Show All

• .NET Development stored procedure Parameter information

My concern is how to make a stored procedure paramter accept null values, do not accept null values and biggest concern is how to check programatically whether parameter accepts null values or not I have used DeriveParameters of commandbuilder class, but no use.

I have also used some system stored procedures but they are also not showing accurately whether parameter accepts null value or not. Please help me out with example stored procedure and programm example in vb.net.

• Silverlight (formerly WPF/E) Store image object in a javascript object

  I currently have an application that creates an image object in pure javascript using the following code: this._image = new Image(); $addHandler(this._image, 'load', Function.createDelegate(this, this._onLoad)); this._image.src = url; The neat thing about this is that I can wait with putting the image element into the HTML document until the browser actually has it loaded. So basically my onLoad function just add's it to the DOM and hides a progress indicator: $get('images').appendChild(this._image); this._image.style.height = "50px"; this._image.style.width = "50px"; $get('progressIndicator').style.display = "none"; Now, I want to do the exact same thing using XAML, but as far as I can see, you j ...Show All

• Smart Device Development JPG image loading and rotation on Pocket PC 2003

  I have developed an app on PocketPC 2003 using VS2005. This application interfaces with a camera and retrieves JPG images from the camera. The app displays the images as thumbnails and allows the user to click the thumbnail to get the full size picture in a scrollable window. This all works fine, however loading the JPG is slow and rotation (the way I am doing it blows out the memory, no leaks that I can find. Image size: 2048(w) X 1536(h)). I am using imgdecmp library to load the JPG image to a DDB bitmap, and implement rotation by converting the DDB to a source DIB, then creating a destination DIB with rotated dimensions, then copy the source DIB to the dest. DIB, one pixel line at a time (very time consuming). When I use the Pict ...Show All
