• Visual Studio Express Editions Cleaning up

  I have a class that contains a looping thread checking for input from a socket. When my application closes I would like this class to stop the thread so the program exits cleanly. I managed to stop it cleanly in my main program by listening for the game.disposed event, but i would like the class to close itself internally when the rest of the program is being cleaned up. Show me the way someone... Keep a reference to the thread instance and call the Abort() method to stop it when your application is closing. Another way would be to have a bool in the class where the thread code is running in declared as volatile. Default the value of the bool is false and when the application is closing it gets set to true. In the thread you check ...Show All

• Visual Basic serialport regex match

  Sometimes I feel so stupid. I am trying to import data from the serial port to my computer. The data will be coming from an alarm system via COM1. What I want to do is, as the data is coming in, capture a line with the word "ALARM" in it and write some text after that word to a textbox. Below is the simple code I am trying to use. If I pull the data in using textbox1.appendtext(serialport1.readexisting), it pulls all the data in fine. But, using the code below, I get the results: ** ***** ** ***** ** ***** ** ***** ** ***** Imports System.Text.RegularExpressions Public Class Form1 Dim strIncoming As String = "" Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Try Se ...Show All

• .NET Development Compile a .NET 2.0 application as .NET 1.1

  I'll start off by saying that I know almost nothing about .NET, so please use very small words. I'm not sure if I am posting this in the correct place, but I will be glad to move it if it doesn't belong here. If you are able to supply a solution, please be as detailed as possible. A very small, very simple C# .NET application was built on the 2.0 .NET framework. Well, .NET 2.0 has not been rolled out to the users that will have access to this program, so they are still using 1.1. These users do not have admin rights on their machines and cannot install the framework. How can I use Visual Studio 2005 to compile this application to work on computers that only have the 1.1 framework installed that is true. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA - Microsoft lack of vision

  Its real sad that Microsoft, once again, shows this lack of vision for a games development tool: 1: Get visual: Don't force users to write such a lot of code to do just very little. It reminds the Charles Petzold's "Hello Window" hell of code days. 2: Provide visual tools: Let users choose the components, change their properties and write just the required code for the events. 3: Quick development means quick prototype and minimum learning curve. XNA has a lot of things to learn. Definetively it is NOT for students and hobbists. We will have to wait until someone encapsulates XNA framework into a group of visual components, that can be easily drag & dropped, inspected and tested very easily without having to learn lots of n ...Show All
