• Game Technologies: DirectX, XNA, XACT, etc. XNA Architectu "push" vs. "pull" model

  Xna.Input.Keyboard has no events OnKeyUp and OnKeyDown, so I can't subscribe any object on this events using delegates. Is any reasons - why I know that I can do this by myself (examine the keyboard state every Update and call those events), but it's an ideological/archetectural question: I don't want to "pull" keyboard every time, I need my objects to be "pushed" on a keyboard event. In general, "push" model improves scalability and maintainance of a system since It's syncronous - each object reacts the event immediatly when event call occur. Having push in a game could potentially be really bad. Many games rely on the rendering to be done as often as possible and game state updates only to h ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA Chatroom

  I personally put up a XNA chatroom to build a community that is already here and to better get to know each other. If you want to quickly inform somebody or get some information or help with something go there. The only problem for me right now is getting idlers in the channel. I know forums are a great way to help people, but sometimes just talking to each other about things like this is even better. Come and idle and help build a community even bigger and also build a place to help each other out. Its XNA Development, its for us. (That would be a sexy slogan). Server: irc.opa-ages.com Channel: #XNA You can use mIRC or any IRC clients in order to get to the chat. .. Or you could just come join the ...Show All

• SQL Server GACUTIL.exe Not Available

  Hello, I am going through some examples on how to build custom tasks, and apparently, I don't have the gacutil.exe utility. I guess it does not come with the .NET Framework 1.1 or 2.0. How do I get this utility Thank you for your help! cdun2 Try installing the .Net Framework SDK 2.0 if it is really nowhere to be found. If you are using Visual Studio, I would have expected to be there as the SDK is part of the default install, it may even be required. Have you done a full Search on your machine It is not included with the smaller .Net Framework redistribution package aimed at client mahines. ...Show All

• Visual Studio Express Editions Minimizing Some Other Softwares To Tray

  Hi! I have this software which does not have a feature which is minimize to tray. I wish to ask if it is possible to write a software which minimizes other .exe files to tray. I wish to minimize the software to tray during startup of my computer. Thanks! Sam well I guess you could do a SendKeys of the Windows Key and the D key, as this forcefully puts all the applications that are up on the screen, minimized to the taskbar. http://msdn2.microsoft.com/en-us/library/system.windows.forms.sendkeys.aspx Another way would be to use the FindWindow API, but you would have to know the names of all the Window titles of the applications, then call an API to minimize them to tray, which ...Show All

• .NET Development RFID Reader Project

  Hello, I'm currently working on a project which involves a serial port RFID Reader. I have connected the Reader to COM2 of my PC and i'm trying to get the signals from the RFID Tags. I'm using Visual C# and SerialPort class. The problem is that i can't read or write to the port. I even tried to write something to the port using port.Writeline("string") and then read it with Readline() but it seems that nothing is written and nothing can be read. When i set the RtsEnable to TRUE the BytesToRead property changed from 0 to 9 no matter what i did and still i couldn't read anything. I also wanted to ask you if you have any code samples to send me or if any of you has written a similar program that works. I need to fix t ...Show All
