• Game Technologies: DirectX, XNA, XACT, etc. Video/Animation Playback - Release #1!

  Hi, I'm currently writing a library (for XNA/DirectX) for animation/soundless video playback, and I have a few design questions for the pros out there if you don't mind answering them : I'm having my animation class inherit from game component, and update the frame depending on game time in the overriden Update method, and render it in the overidden Draw method, but even when I preload my textures to render, playback is choppy. Not sure exactly why, but I notice this only when I have significant number of frames (I noticed it with 100 frames, but *not* with 10/15). This problem may be linked and solved by the 2nd point, so please read on. When I preload all the textures for the frames in the animation (and the no. of frames ...Show All

• Visual Basic Passing a Structure

  I am attempting to pass a structure from one DLL to another. The Structures are identically define in each DLL (Cut-and-Paste), but compiler complains it cannot convert types.

• Visual Studio Team System Importing schema causes full crash in CTP5 (but worked fine with CTP4)

  I had just upgraded from CTP4 to CTP5 and am now having crashing problem (full crash, have to restart VS) trying to import a schema. It was not never a problem importing this same schema in CTP4. Any ideas Thanks I've tried to use the compare schema feature to generate the script, but VS crashed before anything could be generated. I did some more testing and find that this was not a problem when I imported a VERY simple VS 2005 database (1 table, with some data row), which hopefully proves that the environment is correctly setup and that the problem could be with the content of the database I am trying to import that is causing problem. Also, here is some more information about the error: ...Show All

• Windows Forms WebBrowser && HeavyOutput

  Hi, i'm currently using WebBrowser control for heavily text output, but problem is, when there many lines, like about 10k or more, it's getting to eat more and more of your ram, so question is, how to do, then there could be maximum lines (999) in webbrowser, so if i try to output one more line, it deletes first line, then adds new line, and so on Yes, i will just delete everytime there is more than 200 lines, the second line if (this.Document.Body.Children.Count > 2) { //this.Document.Body.Children[1].InnerHtml = ""; //this.Document.Body.Children[1].InnerText = ""; this.Document.Body.Children[1].OuterHtml = ""; //this.Document.Body.Ch ...Show All

• Visual Studio How can I separate the test code from the source code

  our company is planing to introduce unit test into our development phrase.We mainly use Nunit as our test autuomation tool.If we mix the test code with the source code,that is to say, put the test code in the same .cs file with the source code, and we don't want the release build containing the test code, we must separate them when producing the release build.Can we use the preprocess sentences in C# (#define etc.) to wrap our test code, and tell the compiler not to compile the test code when making the release build If so,then we don't need to separate them at all. Thanks for help. Hi Peggy. This forum is for source control. You might get better responses elsewhere. Anyway, #ifdef is one way to keep un ...Show All

• SQL Server Assign XML to variable

  How do I assign XmlDocument results to a variable (so that I can pass it to a sp) I know that the following code works.... select * from tblUsers where userId = 1225 for XML raw It returns "<row UserId="1225" LastName="Evans" FirstName="Stephanie" MiddleInitial=...."), which is what I want. But when I try to assign it, I get an error "Incorrect syntax near 'XML'." declare @strXml nvarchar(1000) set @strXml = (select * from tblUsers where userId = 1225 for XML raw) Ideas It is not possible to do this in SQL Server 2000 using TSQL.

• Visual Studio 2008 (Pre-release) Changing WCF Endpoint at Runtime

  I have a WCF simple service (ServiceA) that I have running on Machine A. I have a client that accesses that Service on Machine A at ( http://MachineA/ServiceA/ ). Simnple enough. Now I have ServiceA running on 4 machines on my network. I still have the client on MachineA. I need to enable the user to connect to any of the 4 machines and call ServiceA. SO basically I need to be able to set the endpoint in code dependant on a selection from the user out of a pool of x machines that would all be running ServiceA. Anyone have a good way to do this with a WCF based service Answered by own question. I added an additional endpoint entry identical to the others with the URLs of my other server machines ...Show All

• Visual Studio Customized Shape

  Hi all, I'm doing DSL project about Image Processing Graph Editor right now. My question is just simple, can I make a drop-down list for a property in the geometry shape Cheers, Herru Hi, I came up with something else.

I tried to set the Custom Attributes of RoomSize so then I can have set of values. But I didnt find the correct attributes class for that. I used System.ComponentModel. Category ( ) to set the categories of my properties, and System.ComponentModel. Description () eto make the descriptions. Do you guys know which class should I use Thanks! Herru ...Show All

• Windows Forms DetailsView Databound event

  Hi all, Should need some help on this : I have a Detailsview "ProductDetails" where some labels have custom formatting, i.e.: < asp : Label ID ="absoluteMargin" runat ="server" OnDataBinding ="ProductDetails_DataBound"></ asp : Label > The formatting occurs when the data is bound. This is only used in the Itemtemplate created for the productinfo. The InsertTemplate should do no formatting because there is no data (yet). But it seems that de ProductsDetails Itemtemplate also reacts on the insert command. I get the exception: "Object reference not set to an intance of an object" for the ProductDetails.DataItem.

• Visual C# Access Controls or Variables on Other Forms: Part II, Attack of the Forms

  Okay, well anyways, you probably remember I posted a thread about this. But....what if I want to access the methods and properties on a form that hasn't been launched from the current form. Let's say there is an options form and a customization form, neither of which are the default forms. I want the options form to modify something, such as background color, of the customize form. How would I go about that I used form2 instance = new form2(this); instance.Show(); but I can't do that because they arent laucnhed from one another... the same things would apply as last time. you would create a class, and just access its properties/methods as long as they are declared as public. If its not launched, then thats fine too - you dont ne ...Show All
