• Game Technologies: DirectX, XNA, XACT, etc. 10-bits per component graphics

  I need to output 10-bits per component graphics but the System.Drawing.Color class only allow 8bits per component (0-255). Any idea Thank you for your patience, hehe, I'm noobie in graphics programming. Just two examples. For the background color I use this: device.Clear(ClearFlags.Target, bckColor, 1.0f, 0); Where bckColor is System.Drawing.Color. And like this for the primitives: vertices = new CustomVertex.TransformedColored[num_vertex]; ... vertices[j].Position = new Vector4(last_x, coord_y, 0.5f, 1.0f); vertices[j].Color = System.Drawing.Color.White.ToArgb(); My app doesn't need very complicated stuff. Just some rectangles filled with gradients, but this grad ...Show All

Before I close the form or do others things (add new row, ...) I want to control if there are changes pendings in the current dataset to display a message.

• Visual Studio 2008 (Pre-release) FaultContractAttribute , May 22 Build With Go-Live

  Hi, We are using the May 22 build of Wcf. This is a version with a Go-Live license. I've noticed that the FaultContract attribute can only be aplied to methods in this build. http://windowssdk.msdn.microsoft.com/en-us/library/system.servicemodel.faultcontractattribute.aspx The documentation here ( http://windowssdk.msdn.microsoft.com/en-us/library/ms733721.aspx ) has a section "Faults for the Entire Contract" For convenience, it is possible to apply the FaultContractAttribute attribute to an entire service contract as opposed to an individual operation. In that case, every operation in the service contract is able to return that type of fault. For example, in the following contract, any operation can return a MathFault: ...Show All

• Visual Studio Express Editions Button to URLs

  Ok, what I want my program to do is: Go through a list of URLs, show progress in a progress bar, and just reload the URLs every 30 seconds. I don't know how to make the button go to the URLs. It doesn't need to display them or anything, just go to them. I also don't know how to make the progress bar link to the button. hmmm. The only thing I can suggest is using the WebClient/HttpWebRequest/HttpWebResponse classes. http://msdn2.microsoft.com/en-gb/library/system.net.webclient.aspx http://msdn2.microsoft.com/en-us/library/system.net.httpwebresponse.aspx http://msdn2.microsoft.com/en-us/library/system.net.httpwebrequest.aspx the WebClient has a credentials property should you require to s ...Show All

• Visual Studio Express Editions How do you close Form1 without shutting down the program?

  I'm writing an application that will use dozens of forms and I want to close the old forms as I launch a new one. When I use: Form1.Close() {Form1 being the traditional first form} it shuts down the entire program as opposed to closing the form and leaving me on Form2. Any advice for a newbie Thanks, Pat Thanks. I would have never found this on my own. As a follow-up, would you have any recommendations as to how to store the names of the launched forms, in order, so that if the "back" button is pressed I can re-load the correct form Just like the Back button on Internet Explorer. I can't seem to make a variable have the right scope to make it accessable from one form to ano ...Show All

• SQL Server Accessing Reporting Services from Internet Issues...

  I have installed SQL Express 2K5 with Reporting Services on a server (on our private LAN) running Server 2003 with SP1. I have requested our ISP to forward port 80 from one of our public IP addresses to the private IP address of the server - I am reasonably confident this is setup properly since they have successfully configured other port forwards for me in the past. With that said, when I try to access the reporting web site from the internet, I receive an IE error message indicating "Internet Explorer cannot display the webpage." I am able to view the reporting website from within the LAN. Windows Firewall is currently disabled. Am I missing something Any suggestions/recommendations would be greatly a ...Show All

• .NET Development What Privilege Do I Need for Low-Priv Server to Listen on Port?

  I am trying to follow Keith Brown's recommendations in his book "The .NET Devloper's Guide to Security". I have created a server app using HttpListener. The server app runs fine when logged in as Administrator, but when I created a user account and assigned to the Users Group I get an "Access Denied" on the listener.Start() method. I am not sure how to determine what level of security I need to perform this operation. Thanks M.D.A I'm looking to try this as well...implement an HTTP listener class, but grant the proper permissions through code so our end-user doesn't have to run the httpcfg utility. Thanks!
