• Game Technologies: DirectX, XNA, XACT, etc. Texture2D.GetData fails on 500x500 texture

  Hi, i am reading of a Texture2D the given colors to extract my height data of a heightmap image. Therefor i use this code: Int32[] data = new Int32[heightMap.Width * heightMap.Height]; heightMap.GetData<Int32>(data); heightMap is a Texture2D object with a width and height of 500, so the data-array gets at runtime a size of 250.000. Fine but it fails on getting the data from the Texture2D by using the GetData function with this error: The type you are using for T in this method is an invalid size for this resource. I found something with google where people switched to Color instead of Int32 but for me it doesn't work it's returns the same error I used a smaller heightmap before with a resolution of 128x128 this works!!

• Software Development for Windows Vista How do you host WWF 3.0 as a webservice (instead of using ASP.NET as a host)?

  Tom/Vihang/All WWF Gurus, Can someone please provide an example of how to host WWF 3.0 workflows as a webservice, instead of using IIS (ASP.NET) to call and host XOML only workflows Tom has provided examples of ASP.NET hosting and calling XOML only workflows (using tracking and persistence). I need to do the same with a centralized web service. The labs provided with WWF 3.0 are very similar to WWF 2.0 labs. I cannot find any examples that offer samples on how to host workflow runtime services via a webservice that can be consumed by one or more websites (on one or more webservers). MS suggests using a centralized webservice to host workflow runtime services, instead of using IIS. Unfortunately I did not find any code examples (I ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. ? Beginners

  My friends and I have no experience with coding or anything like that but have taken an interest in XNA and have some ideas that we would like to try to create. How easy is XNA going to be to use to make a simple 2d game just for fun I know it uses C# and I am going to start trying to learn, but is this going to be something where only experts can use this program, or is someone like myself going to be able to create at least simple games and not have to spend hundreds of years doing it I am also a beginner on Visual C#, but with the help of the absolute beginners videos wich are also on the microsoft site, you can learn a lot, so i have taken the oppurtunity to watch those lessons, and trying something ou ...Show All

• Smart Device Development random TypeLoadException

  I am having real issues with a TypeLoadException that occurs generally randomly. I've been working on a .NETCF 2.0 app all day, debugging and generally being productive. All of a sudden, with no changes to the assemblies, I get a TypeLoadException on one of the types in one of my referenced assemblies. It's one of my own assemblies, and I checked the manifest and didn't notice anything untoward. // Metadata version: v2.0.50727 .assembly extern mscorlib { .publickeytoken = (96 9D B8 05 3D 33 22 AC ) // ....=3". .ver 2:0:0:0 } .assembly extern retargetable System.Data { .publickeytoken = (96 9D B8 05 3D 33 22 AC ) // ....=3". .ver 2:0:0:0 } .assembly extern retargetable System.Xml { .publickeytoken = (96 9D B8 05 3D 33 22 AC ) ...Show All

• .NET Development Custom Collections and Custom Events in Web Services

  Hi, I have a Web Service that returns a Custom Collection. So my Web Services client proxy class that was autogenerated has a array of objects that correspond to my custom collection on the server. This is working fine for me. My question is: I have a requirement that when some specific changes occur in the object array on the client side, I should be able to catch that change. Suppose I have a CustomCollection on server called 'EmployeeCollection' (Collection of Employee). Employee has only two attributes EmployeeID and Salary. So when I generate a client proxy, I get a Employee class on the client and an Employee[] that corresponds to EmployeeCollection. Now at runtime, when Employee[] on the client is populated and if ...Show All

  I use a open source codec/video library (libavcodec). This lib exposes the video frames as 24_bit RGB bitmaps in memory.
