• Visual Studio 2008 (Pre-release) Simple watermark effect

  I'm trying to create a simple watermark effect in my interface using XAML and replicate an effect I used to do in WinForms. The effect is a large 256x256px graphics file that remains anchored to the bottom right corner of the container (with some margin and transparency). I do know there are such things as the ImageBrush to work with pre-set bitmaps, but I need something which won't make the file go beyond its original size when the window is resized. The object I'm applying it to is already hosting functional controls and I'd like to avoid having to somehow layer a canvas in somewhere and mess up the automatic grid's I'm using for everything else. ...Show All

• Software Development for Windows Vista Is there automatic reloading and executing when recovering from a crash?

  Hi This may be a stupid question but I really need to know what to do in this case. I'm developing a state machine workflow, I have an EventDrivenActivity with a TransactionScopeAcitivty in which I have activities to save to my data model. If something goes horribly wrong after the persistence point on the close of the TransactionScopeActivity before the persistence on idle (I have this set). Can I expect that when the outside factors are resolved the runtime will take care of reloading this partially complete EventDrivenActivity automatically and finish exection from after the TransactionScopeActivty. Or... am I going to need to somehow check for this situation and load the workflow instance to have it continue exection Any help wo ...Show All

• .NET Development HttpWebRequest encoding

  Hi, is there a way to control the character set (encoding) used by the HttpWebRequest class I'm having problems with a request that has querystring parameters whose values contain accented characters ("e", for example). If I create the HttpWebRequest from a string they are (correctly) url-encoded, but unfortunately the server I'm requesting from does NOT url-decode the parameter values! I've made the same HTTP GET from IE using both escaped strings and simply typing the accented characters straight into the address bar. I get the correct response only in the latter case. So I tried to construct my HttpWebRequest from a Uri instance instead, using the (string url, bool dontEscape) constructor to avoid url-encoding. Lookin ...Show All

  Hi gurus, The company in which I work experiences in developing Windows Forms applications and we have developed a kind of 3-tired architecture for that kind of programs but for some business reasons we have to produce some web applications with ASP.NET and we have problems designing an architecture for these new apps because of the major differences between Web and Windows application models.

• Visual Studio Express Editions Favicon editor?

  I have installed Visual C++ 2005 Express. Is there a favicon editor in it If so, where is it, and is there a tutorial If not, what do you recommend for a newbie to make favicons 1. There is no image editor of any kind included in VC++ 2005 Express. 2. There is a good Wikipedia article that also serves as a brief tutorial. 3. You can use an icon editor (search the public software download sites) or you can use any image creation software that allows you to save a small GIF or PNG file. You can even use Microsoft Windows Paint, which is part of any Windows system that Visual C++ 2005 Express Edition runs on. The version on Windows XP Pro will save files in PNG and GIF formats.

• Game Technologies: DirectX, XNA, XACT, etc. Need a practical walkthrough for XNA

  Hi. Does anyone know where I can find a practical and step by step walkthrough for XNA to create a simple 3D box(cube) I'd be happy if you could also lead me to the source of MS walkthroughs for XNA. The documentation for XNA itself does provide a walkthrough for this purpose, but it seems buggy. I need a fresh one! This is the first Beta, most people have been dealing with this framework for less than a week. There might be a tutorial that simple out right now, but I haven't seen it yet. So you might have to wait a few more weeks for more people to get their feet wet and explore it a bit more. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Managed Direct3D 10

  Since XNA only supports DirectX 9.0 Where is Managed Direct3D 10 I hope there will be Managed wrapper for Direct3D 10 thanks You’re right in saying that there isn’t that much we could do that you can’t – but we are interested in doing an official version of MDX10 and we’re currently researching our options. What we’re looking to do is have parity with the native APIs as much as possible to ensure developers have the same power in .NET as they do in native. Stay tuned for updates, betas, news… It’s important to note that unless you want D3D10 specific features (for which there’s no hardware available yet) XNA Express is an excellent option for game development.

• Software Development for Windows Vista Custom Service loading from a different client request

  When I receive a web service request to the existing workflow instance, it can't find the service that I created earlier.
