Steve Maier, MCSD MCAD DMX protocol Alicia Visser7-Sep-04 1:51 Alicia Visser 7-Sep-04 1:51  I'm a student. My project group and I are doing a project - creating an appication for controlling stage lights. We code in C# and need to know more about DMX512 or where we can find info about it. We need to develop a dongle to communicate with the DMX devices. Help is needed urgently. Time is very limited! (Any info will be appreciated) Thanx!

Your application has then to create this heartbeat signal regularly (maybe in the working thread). The heartbeat signal can be a pipe or socket connection or something like that. Hope that helps. Greets Roland Re: Not Responding sreejith ss nair7-Sep-04 1:36 sreejith ss nair 7-Sep-04 1:36  hi, i am hearing this thing first time. How ? Where ? i start working on this new idea (for me) ************************** S r e e j i t h N a i r ************************** Re: Not Responding Roland Bär7-Sep-04 2:17 Roland Bär 7-Sep-04 2:17  Sorry, but i haven't any Code that I can give to you, but I try to explain you the mechanism a little bit more specific. The idea is to have a TCP/IP Connection between the Application thats needed to be observed (lets call it "Application A") and the Application that will observe Application A and create an alarm (Application B). One application should be an "server" (create a socket and start listening) while the other should be the "client" (create a socket and connect to the server). When the connection between the two applications is established, you can send periodically (ex. all 10 seconds) messages from Application A to Application B (ex. "alive"). When Application B does not get an "alive" message 20 seconds after the last "alive" message, Application B should create an alarm, stop and restart Application A or do something else. If you haven't worked with sockets under C# have a look at the various articles here on codeproject. Hope you will get with this information a step further.

This can occur because your main (GUI-)thread is performing a long-running action. In that case you _can_ do something like monitor your application. First step would be to fork out the possibly not responding functionality to a separate thread that can be monitored and aborted if it hasn't finished in a given time. Regards, mav Re: Not Responding sreejith ss nair7-Sep-04 4:44 sreejith ss nair 7-Sep-04 4:44  hi mav.northwind wrote An application is marked as "not responding" if it's not processing windows messages for a given time What you mean by Marking ? See i can't long running process. Cause it is pulrly depend on users who is using this s/w. If i want to mark then i need to mark all. If i wrote some service then upto how much extend i will help me? I am not at all good in service but still i can manage. ************************** S r e e j i t h N a i r ************************** Re: Not Responding mav.northwind7-Sep-04 5:21 mav.northwind 7-Sep-04 5:21  I meant the TaskManager showing an application as "not responding". Or are you talking about a different sort of "not responding"? Re: Not Responding sreejith ss nair7-Sep-04 5:31 sreejith ss nair 7-Sep-04 5:31  hi, Did you read the entire thred related to this heading ? I will tell i want to know if my dotnet application is "not responding state". For that purpose what we can do is, we can write a paraell service which will monitor my application on a regular interval. I am not that much good in Service. But still i can manage. What is your idea ? Any better idea than this or can i go for a service. Is so which service i want to write. ************************** S r e e j i t h N a i r ************************** Re: Not Responding mav.northwind7-Sep-04 5:43 mav.northwind 7-Sep-04 5:43  Yes, I read the thread, and I think you want to find out _within_ your application why it is not responding. So the core question is: What is your application doing while it's "not responding"? What steps are causing your application not to respond? If you can identify these actions then you can execute them in a separate thread, so that your application itself will no longer hang, only this specific thread, so there'd be no need for a separate monitoring service. mav Re: Not Responding Roland Bär21-Sep-04 21:59 Roland Bär 21-Sep-04 21:59  If you are still interested in this topic: I've wrote an article about the Topic. Greets Roland Launching Application mathon7-Sep-04 0:48 mathon 7-Sep-04 0:48  Hello, When i deploy a Smart Device Application on my real PocketPc the application starts when in the output window of my VS.NET the statement Launching Application appears. But how can i stop the application again? do i only have to close the window of the Smart Device Application? because sometimes when i want to deploy the Smart Device Application again an error occurs on the PocketPc that the application have to be derminate bevor, although i have closed the window on the PocketPc...?? thx mat Re: Launching Application Heath Stewart7-Sep-04 7:00 Heath Stewart 7-Sep-04 7:00  You have to close the emulator. Closing the window of an application does not stop the process (except in a few, specially programmed applications). Programs continue to run when they're not visible. For debugging, if you like, you could add an extra menu item that actually quits the application as opposed to closing the window. There is a big difference.

If a row has null values on display it appears as "(null)" (or whatever you set the "null text" column property to) but after a user enters a value, how can they choose to replace the value with a null?
