• Game Technologies: DirectX, XNA, XACT, etc. A Simple 2D Map Editor

  I've built a simple XNA 2D map editor for fun that mixes xna and winforms. It supports 20 layers, multiframe and animating textures, and has grid snap. It's very basic and small, intended mainly as a learning experience. Grab here: http://webpages.charter.net/kharza/WorldWalker.zip Enjoy! Kenneth Thanks for the suggestions! Feel free to put it on your site if you wish. I didn't even think about the layer's scrolling differently. That seems like a no brainer. I was thinking in top down ultima mode. The flickering sprite shows which placed sprite is selected in the layer editor. With the layer editor you can change the values for the individual sprites placed down, or delete them.

• Software Development for Windows Vista How to orchestrate external application screens ?

  Hello, I am currently investigating if Workflow Foundation could be used in my specific case: - define a task sequence - each task is a human task to accomplish - the task is defined as an URL to some specific web pages - once the user click close on a specific web page, the control returns to Workflow Foundation - WF Foundation can run a java class to determine what is the next task to accomplish My questions: - Can WF Foundation trigger some external web pages - What is the expected return (on WF Foundation side) when the user quits the web page - Can WF Foundation call some java class Thanks !

• SQL Server Intermittent ole db error

  I have this problem occuring intermittently: When I try to add a package to the project, and click on the Package path button. I get a oledb error x080004005 (client unable to establish connection)... After I click ok, and click on the Package path again 2 or 3 times, the error goes away and I get the list of packages displayed. Some time I get an empty list box.

Once it is in the database I do not get any error message. This is what I have: I have sql 2005 installed. Microsoft SQL Server Management Studio ...Show All

• Visual C++ Beginner question - ExitInstance()

  Hello all, I have a very basic question: How does one go about overriding your app's ExitInstance() function I'm using VC++ 2005, so I tried right-clicking on the app class in the Class View , selecting "Add->Add Function...". Of course, I know the function name ("ExitInstance") and I know I need to select the "virtual" check box, but I don't know the return type, and the parameter list should be empty but the "parameter type" list box doesn't contain such an option (i.e. I must pick a parameter type). Anyone Thanks in advance! ...Show All

So, the problem is that new UpdaterConfigurationView().ManifestManager is always null value, due to t ...Show All

• .NET Development Application Authentication

  Is there any way to control access to an application. This application would be a stand alone app not connected to the web in any way but need to authenticate specific users to keep the unprivileged user from accessing the documents in the app. Ive looked online and in a local bookstore and all I can unearth are references to web authentication. I konw there is a way to authenticate with the current user logged in in XP but I would rather not restrict the app to only being used whilst on your login. Any ideas Thomas I've never done either. Would you mind explaining what each of those would need I'm new to the world of VC# programing and VS. Thanks Thomas ...Show All

• .NET Development Are there Different variations of framework for the same .NET Framework version?

  I have a product that is used by thousands of users across the globe. .NET Framework has been the life saver by providing a standardized reference environment. The software has been running relatively troublefree until recently. My software does a digital signature check and makes a call to DSASignatureDeformatter.VerifySignature using the SHA1 algorithm. This particular user, from Australia, running Windows XP and .NET Framework 1.1.4322, returns the error: CryptoAPI cryptographic service provider (CSP) for this implementation could not be acquired.

• .NET Development how to display text on the image

  hi, I have displayed the image in the picturebox . i can do zooming of the image. I would like to display some text on the image without affecting the zoom of the image can anyone help me in this regards, Singam. Actually you can do it programmatically. The way you would do it is to build a new bitmap based on the old one. Here's an example: WebResponse resp = WebRequest .Create( "http://www.google.co.uk/intl/en_uk/images/logo.gif" ).GetResponse(); Bitmap originalBitmap = new Bitmap (resp.GetResponseStream()); Bitmap annotatedBitmap = new Bitmap (originalBitmap.Width, originalBitmap.Height); using ( Graphics g = Graphics .FromImage(annotatedBit ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. DX10 and XNA

  Hi. Are there any future plans for the XNA framework be upgraded to support DX10 features and retain compatibility with Xbox I read how radical the new API will be and it will not be backwardly compatible with DX9. Although Vista can still run DX9 games, it will be slower as it will be via a software layer. since DX10 will also need new graphics hardware too, that suggest to me that XNA may not ever access DX10 functionality. Unless a new Xbox is on the horizon. The only software layer that Direct3D 9 on Vista uses is the runtime. But on XP it needs a runtime too. As the new Vista runtime can do many things much smarter (because of a new driver model) it is possible that Direct3D 9 will run faster on ...Show All
