• Visual Basic Binding Combobox to Data Class - .Text or Lookup?

  Hi Everyone, I have 2 combo boxes on my form, which are made visible when the user needs to select (text) values for “Category” and “Location” fields. These values are actually stored in the database as foreign keys. Because the available Categories and Locations rarely change, I populate the combos when the form loads. This saves me running back to the database every time they need to be captured or altered. I have bound each combo box’s “text” property to the corresponding data property in my data class. The class properties handle the resolution between the text value and the foreign key value via private data tables (i.e. lookup tables), which are populated when the class is initialised. (This makes the code in my class more readable ...Show All

• Visual C# Screen Saver notifications

  I want to get notifications of various System Events in my C# app (Shut down, logoff, Session change, etc). So far I found that the SystemEvents class is very useful ( http://msdn2.microsoft.com/en-us/library/microsoft.win32.systemevents_members.aspx ) However it is missing the notifications for Screen Saver start and stop. Does anybody have an idea to subscribe to Screen Saver events Regards Thanks for the reply and hint. However, I need to trigger the event of a screen saver starts as soon it happens (by registering a delegate or to an event). I am doing a 3D preview that I want to stop as soon as the screen saver starts, and then resume the preview when the screen saver stops ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Shader states, etc? (HLSL effects not working right)

  I'd like to call upon all the shader gurus here for some help :) I've been experimenting with writing some of my own effects, meaning I'm a HLSL newbie, and have been using NVIDIA's FX Composer to do my work. After producing a cool (albeit simple) effect, I decided to try using it in my little model viewer. The problem is that the way it shows up through XNA is different than the way it shows up in FX Composer, and I can't figure out why. You can find the code to my effect here: http://www.hiranipra.com/data/help_attach/gb1_shader.txt - it's just fairly simple environment mapping-ish stuff. A screenshot of what it looks like in FX Composer: http://www.hiranipra.com/data/help_attach/FxComposer1.jpg - it's hard to tell, but the ...Show All

• Visual Basic Help Making A Simple Web Browser

  Hello everyone I was wondering if anyone could help me. Im trying to put a Progress Bar in My Web Browser to see How much og the Page Has Loaded like in IE. Thanks alot Brad implement the ProgressChanged event of the webbrowser control. This event is fired when the progress changes of the downloaded document. the event gives you a WebBrowserProgressChangedEventArgs. In here there are 2 properties, one is CurrentProgress and the other is Maximum progress. So with these 2 I guess you can do some calc or just keep seeing what the currentProgress downloaded is and build up your progress bar this way. http://msdn2.microsoft.com/en-us/library/system.windows.forms.webbrowser.progresschanged.as ...Show All

• Visual Studio Express Editions Encryption

  Hi, I am making a simple (not very secure) chat program. This is basically how it works: The user signs in with a username and password. (Database already done) The username is used as the senders name. When the user sends a message the recipients name is carried with that message and stored in a remote sql database. (database already done) When the message is in the database the recipient who has also signed in is able to see it. In other words a query to see if the name of the person the message is for matches the name of someone signed in. I would like help with these portions of it and i would like to include encryption if possible. I know this is a lot to ask but it would be helpfull to get information on this. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Files and endianness

  Hello, First I'd like to say thanks to the guys at MS for being so open about the development of the XNA Framework and associated tools. The recent blog posts have been really excellent. At the moment for opening files I use File.OpenRead(). To read the data from the Stream it returns, I use Stream.ReadInt32() and so on. Obviously on my little endian PC platform, reading little endian data, there is no problem. But on the Xbox, does System.IO.Stream exist And if so, does Stream.Read*() do endian conversion on the fly Thanks again, Peter In .NET, the long type is always 64 bit. The standard C# types are: byte = 8 bit unsigned sbyte = 8 bit signed short = 16 bit signed ushort = 16 bit unsigned int = 32 bit signed ...Show All
