I was trying to use the System.Threading.Timer to run a function every 250ms - but I'm finding it difficult to cancel the timer from within the callback function. I can't seem to find a reference to "this" (js has this - it's so nice). At any rate - how could I start a callback running 250ms from now - without a timer - and then if I want to continue it again do another start for 250ms.

decSubTotal = msgInput + decSubTotal
txtItemPrice.Text = msgInput.ToString("C2")

This should be simple, but the answer is eluding me. If I've got a Save action in my controller, and the save fails, how do I cancel the action without disturbing what the user entered? For example, Index is strongly-typed of "MyTable":
Function Index() As ActionResult
ViewData("message") = "Hello"
Return View(New MyTable)
[Code]....
In the Catch, if I put Return View(form), I lose the message passed via ViewData. If I redirect to Index, I'll lose what the user entered. I think I've seen the simple (correct) way to handle this before, but if you don't know what to search for, it's hard to find.

I was hoping somebody out there could help me please, I have an application which uses threading, process and runs cmd.exe - the problem I have is that I cant cancel the command.I have one textbox and two command buttonts, button 1 is run and button 2 is cancel - for this testing purpose only (my app wont be pinging but I'm doing this for testing only) I'm hoping to enter an I.P address in the textbox and then click on Run which starts a thread and the process, which so far is working.the coding I use to run the command is.[code]Now comes to difficult part, whilst the command is running I want to click on cancel which kills the thread and process which I have done but I have hit a brick wall because even though my thread and process has been killed my command carried on running, what I would like is the moment the cancel button is clicked to kill the thread, process and the command.
View 2 RepliesI am not familiar with threads, but the project I am working on has a bunch of them. There's a thread for the main form, then threads for activities like a calculation, converting files, etc, so that the user can kick off a calculation job and then kick of a conversion job that will run at the same time. Typically, calculations can run for hours and hours; conversions and other threads may only run a few minutes.If the calculation runs into a problem, how do I cancel that thread? It looks like the threads are controlled (driven?) by the main form, but I'm at a bit of a loss.....

View 3 RepliesHow do I add a cancel button to a message box? I really need to know this because it is kinda stupid that i have a message box saying "Are you sure you want to clear everything?" and have no cancel button. Also what code do i need to make a program key where it is made so that I give a key and it works with that specific program another one will be made with a different key. I have no code for that because i have no clue where to begin (3 day trial code so it is locked would be nice to) The other problem I have is makeing the program open new windows so if i click trial then it will run for 3 days then done and with code making it run forever without the pop up again so how do I do all that?
