does it make sense to use a backgroundwoker that includes a parallel process that starts many
processes if during this the full application is frozen by the parallel stuff itself?
Does anyone have any practical examples where F# would be a better choice than C# or VB.NET? Please can you demonstrate using source code?
View 8 RepliesSo my teacher gave us this assignment that I'm having trouble understanding why she wants us to write outside of the button Private Sub.1. Write the code for the Calculate Total and Grand Total button a. Declare a variable to accumulate the individual totals outside the sub procedures b. Calculate the total by multiplying the selected number of atendees by the selected cost, and display this total in the label next to Total c. Calculate the grand total by adding the total calculated in step 3.b to the grand total variable. Display the grand total next to Grand Total I'm don't understand why she says 1a. I feel like you can just write all the variables in the same Sub on the calculate button.

View 1 RepliesI need to pass some data to some procedure called with a parralel.invoke, how can I pass data to the procedure?

I have a list of strings that I need to pass to a process in a different class. What I want to know which of the two ideas would be a better approach to use in terms of speed,efficiency and parallel processing. The list contains +- 10000 strings and I want to limit the threads appropriately to have only about 5threads running at one time:
For i as integer = 0 to searchPages.Count - 1
Parallel.For(0,10,Sub(x)
ps.processPage(searchPages.Item(i))
[code].....
I have a list of(myclass)each item of this list need to be elaborated before being inserted in the list.Is it safe to use parrallel processes to fill shared list where each process has to fill a predefine range of the list? Or is it necessary to freeze the list when one process is filling it? in other words: can many process fill the same list in the same time without problems
View 16 Repliesi have problem with the reportprogress / progress changed.i use the backgroundworker in a form class named frame menu. the do work sub of the backgroundworker calls a sub X in a public module.
from the backgroundworker do work sub i am able to use the backgroundworker.reportprogress / backgroundworker progress change method and this is displayed on my form.
when i am using the backgroundworker.reportprogress / backgroundworker progress change method from the sub X it does not display on my form.
when i debug the code it calls the backgroundworker.reportprogress / backgroundworker progress change method correctly in the sub X but just does not display it on the form.

I have a service that scans network folders using a parallel.for method. However recently I am finding if I stop the service then while windows says the service is stopped the process is still running in task manager. However it is at 0 cpu and the memory does not change. If I try and end the task (even a force in command prompt) it just says access denied and i have to reboot the server. What would be the best way to make sure everything terminates? I thought of adding a global Boolean that in the stop procedure it turns true and part of my parallel code will check for that and call s.stop.

I have written a windows service that is meant to launch a notepad when a specific action happens. The problem i have is that even though the service launches notepad, the actual notepad it self is NOT visible. I know that it has been launced because i can see the process in the task manager. By the way the process is listed as a SYSTEM process rather than a process under my user name (i believe that is because my process is a "LocalSystem" one).

View 4 RepliesWhats the best way to insure only 1 copy of the software is running (ex. not allowing the user to open the software twice when its running)

I have tried to make a program not able to be forced to close by naming it the same as a system process. However, this only works on XP, not on Vista. I don't actually mind if the program is closed but I would like something to happen when it is, thus being able to end the process is not good.Is there any event that can contain code to be run when the process is stopped? I'm guessing not but it's worth asking. If not, is there any other way to stop this? Maybe have 2 programs continually watching for each other or something?

I am working on a Windows Service project that is supposed to start automatically with Windows and it has a timer to check if a certain process is created (in this case "iexplorer") the service should terminate that process. In addition, the user should not be able to stop the windows service.
I was able to create the process and make start with Windows. I changed the property (CanStop) to False but that did not help because after a few tries the servise stops. I used a For-Next loop in the timer to check for the process to terminate but unfortunatly, it didn't work. The code I used is:
Dim theProcesses() As Process = System.Diagnostics.Process.GetProcessesByName("Iexplore")
For Each currentProcess As Process In theProcesses
