You can't override the Undo operation on the RTB to do this. What you would have to do is roll your own Undo/Redo mechanism and use that.

Hello,
I am new to C# threading and I am having problems accomplishing a task. To give a quick overview as to what I am trying to do: I have many user controls on a single form that each present different data. This is a small utility that displays the status of different applications and systems. Each user control, as of now, has two threads. 1 thread will update the data source and the other thread will update the user interface.
My problem is that I do not wish to lock the Form while one user control tries to update itself. I have tried two approaches.
1.) I called lock(myDataTable) and performed all updates to the datatable before the thread is called to update the user interface. This did not work until I changed my code to lock(this). I was getting threading errors where the datatable was only about 1/2 populated. When I switched over to lock(this), my gui started locking again on an update.
2.) Thread the threads (god help me). I have two methods: updateData and updateGui. I made a wrapper method called refreshAll that would create a new thread job on updateData, sleep until it was finished, and then make another threaded call to updateGui. When my timer tick event fired I would make a threaded call to refreshAll. Big surprise on this giving me weird gui hang-ups.
Sorry if this is confusing. I will re-iterate on areas if I was not clear. Any help / approaches would be much appreciated. Thanks!

Hello,
Have you invoked the method which refreshes the GUI?
All the best,
Martin

Yes:
private delegate void displayCallback();
private void display()
{
if (InvokeRequired)
{
BeginInvoke(new displayCallback(display));
return;
}
....
}

What causes an update? You have a data source that's being updated as well as a user interface, so where does the update come from?
If the updates take awhile, can you represent the progress of the update to the user (probably using a progress bar) so that the app doesn't appear stuck?
More info is needed.

Hi all,
i am writing an application to communicate between local and remote machine using STAF tool.
I can have a one way communcation but i want to have a both way communication. Like local machine abc.exe runs def.exe over remote machine and then remote machine goes back to local machine to ask what task to perform and then local exe says calc.exe to run and remote machine performs that.
So below is the psueudo code to achieve this but could any one help me out in converting this to C#.NET. i tried this out but i am getting exception at the moment. So here is the psuedo code
abc.exe (started by machineA)
-- STAFHandle::create("ABCApp", handle);
-- handle->submit("machineB", "PROCESS", "START COMMAND def.exe");
-- handle->submit("local", "QUEUE", "GET WAIT");
---- when the "ReadyForInput" message is received from DEFApp,
----- handle->submit("machineB", "QUEUE", "QUEUE NAME DEFApp MESSAGE Start:Calc");
---- when the "Finished" message is received from DEFApp, continue to next executable to run and queue another message to DEFApp, etc...
def.exe (started, by abc.exe, on machineB)
-- STAFHandle::create("DEFApp", handle);
-- handle->submit("machineA", "QUEUE", "QUEUE NAME ABCApp MESSAGE ReadyForInput");
-- handle->submit("lcoal", "QUEUE", "GET WAIT");
--- when the "Start" message is received from ABCApp, parse the program to run (Calc)
---- handle->submit("local", "PROCESS", "START COMMAND Calc.exe");
---- when Calc.exe completes,
----- handle->submit("machineA", "QUEUE", "QUEUE NAME ABCApp MESSAGE Finished:Calc");
//submit function is already created with parameters which submits the command to local or remote machine.
Thanks a lot.

Show us the code you got so far and tell us what exception you're getting.
It's quite hopeless to wait for someone turning your pseudo-code into running C# code. This is a forum for helping others with their problems and not doing their whole work.

ok this is what i did,
ABC.EXE LOCAL MACHINE
here local machine is machine A and remote machine is machine B
static void main()
{
STAFHandle handle = new STAFHandle("MyProgram");
handle.submit("machine B", "process", "start command C:\\def.exe");
handle.submit("<machine a="">", "QUEUE", "GET WAIT");
handle.submit("machine B", "QUEUE", "Queue NAME YourProgram MESSAGE Start:calc");
}
DEF.EXE REMOTE MACHINE
here local machine is machine A and remote machine is B
static void main()
{
STAFHandle handle = new STAFHandle("YourProgram");
handle.submit("<machine a="">", "QUEUE", "QUEUE NAME MyProg MESSAGE ReadyForInput");
handle.submit("<machine b="">", "QUEUE", "GET WAIT");
handle.submit("machine B", "PROCESS", "START COMMAND Calc.exe");
handle.submit("machineA", "QUEUE", "QUEUE NAME MyProgram MESSAGE Finished:Calc");
}
so when i step over abc.exe, the moment it execute
handle.submit("machine B", "process", "start command C:\\def.exe");
i get error over remote system that def.exe has encountered a problem and needs to be closed.
SO any idea how to solve this and process, queue are services already defined in STAF
Thanks

Better to try convertors available free to download, But doest guarantees the bug free code.

Not a good idea as its only a small piece of psuedo code. And i guess to convert you need a running applciation.
Anyway Thanks

Hi,
I would like to write a .Net Assembly that should run as a scheduled
task in windows. I dont need any user interface. What kind of project I need to create in Visual Studio for this solution? Please help and also any samples would be helpful too.
Thanks in adv.

You probably want to create a window service. A windows service will run even when no one is logged into the computer, which is often desired when you have scheduled tasks. You do have to run the installutil to install a .net windows service, so that can be a little complicated. You also need a login and password for the service to run as.
I wrote an article that has a windows service in the sample code.
http://www.codeproject.com/dotnet/OpenFiles.asp[^]
It isn't a scheduler windows service it just checks things on a timer, still it can give you an idea what what a windows service looks like.
Usually you need to add a timer control to the windows service to get a scheduler to work anyway. If you know what time you want the schedule task to run you se the timers elapse time to be the correct amount of milli seconds before the event should run. Then the timers elapsed method will fire. Once that method is over at the end you should re-set the elapsetime to the proper amount of time before it should run again.
Well, I hope that helps.

Which edition of Visual Studio .NET 2005 are you using? The Class Diagram doesn't exist in the Express Edition. It's only available in the Standard, Professional, and Team System Editions.
