• Smart Device Development Establishing a Connection from Server to Pocket PC through GPRS

  Hi, Most pocket pc applications that I see requires the pocket pc to establish a connection through GPRS to a server (in my case Tomcat)  in order to get some Data. However I am curious on how things work the other way around. Meaning, what if I want to get the Server to establish a connection to the pocket pc Are there any classess available in the .NET framework in order to handle this I am thinking that maybe there is an existing listener that i can use As an addition, is there a way for a pocket pc 2003 emulator to "simulate" connecting to a GPRS network Other forums say that as long as ur desktop pc is connected to the internet or ...Show All

• Windows Forms graphics flicker problem (double buffer not working)

  I am trying to create a simple Breakout type game. I have a game panel on my form that holds my game (the paddle, ball, and board of blocks). I use a timer with an interval of 10 to move the ball a set distance every tick. The problem is that I also draw the board everytime this timer ticks and it flickers. I tried setting the doublebuffered attribute of my form to true but it didnt help. Anyone have any ideas either a different/ebtter way to buffer it or a different way of drawing the board I tried making a new panel on top of my game panel to just draw the board in but that didnt work for me either (unless I did something wrong).

• Visual Studio How to .Get() empty VSS 2005 Projects\Folders programmatically from within VS 2005?

  I have a question relating the the VSS functionality in a VS 2005 project of mine. When I 'Get the latest version' of a project within Visual Source Safe directly, it 'Gets' the entire project\folder structure even if several projects\folders are empty. However, if I instantiate a VSS Database object within my VS 2005 project and then .get_Item() to a VSS Item object, then do a recursive .Get() ONLY projects\folders that have files in them are pulled down and gotten. I can't find an appropriate flag to accomplish an entire .Get() of even empty projects\folders in VSS 2005 and I am wondering what I must do in order to accomplish this T ...Show All

• Architecture General business object requirements

  For those of you who have worked on medium to large sized projects, or anyone who has an opinion , I would like to know what types of logic an application needs in the business layer. If the objects expose properties and collections, is a simple validation on write all that's needed I guess the objects also have methods that do various things. If anyone feels like offering any insight into the kinds of things their business objects do besides store bits of information that would be greatly appreciated. I'd also like to know what types of exceptions are generally thrown when persisting to a database. What about errors in the middle of bat ...Show All

I've tried casting to an object but this doesnt work :-/ also tried a pointer member variable in my class but compiler complains about it. how am i supposed to do this in c# Here's a few examples. A lot of code but all this really clarifies some issues. Just run the tests and you'll see.

• .NET Development Is System.TimeZone appropriate as a base class?

  It would seem that, as a friendly .NET developer, I would want to write concrete TimeZone classes that implement the abstract TimeZone interface provided by the .NET framework.  However, after a thorough examination of the MSDN documentation, this seems impossible.  Note that all of my statements here are based on the assumption that "local date and time" in MSDN always means "machine local date and time."  I have not found any evidence to suggest otherwise. The primary problem with the TimeZone interface is that it provides no methods for translating a given time from UTC to the actual concrete time zo ...Show All
