I have an array that is a list of files in a folder, I'm processing the files and renaming them. It takes about 15 minutes to rename them all, this is done daily. I currently have 1 Backgroundworker to handle this and update the UI. My question is, this: How can I use more than 1 Backgroundworker to use more than 25% of the CPU to do t...
The active object pattern was mentioned on Stack Overflow here. I have used the background worker class in C# in the past. The active object pattern looks interesting but more complicated. When should the active object pattern be used instead of the background worker class? ...

Hey, so got a new problem... I'm writing a multithreaded proxychecker in c#. I'm using BackgroundWorkers to solve the multithreading problem. But i have problems coordinating and assigning the proxys left in queue to the runnning workers. It works most of the time but sometimes no result comes back so some proxys get 'lost' during th...
Hey all, I would like to know if it is possible to get 'leftover' calls to AsyncTask#onProgressUpdate after AsyncTask#onPostExecute has been called? I am setting text on the same TextView using both of them, and I don't want to set text such as "Done!" and then have it overwritten at a later point by text such as "Almost there - 90%" ...

Normally, when I want to cancel a backgroundWorker in C# I will do something like this: while (backgroundWorker1.IsBusy) { backgroundWorker1.CancelAsync(); autoResetEvent1.WaitOne(BGW_CANCEL_TIMEOUT); } In one application there are a number of backgroundWorkers. Is it valid to use a helper-function to c...
Ok, here's the scenario. I have an ASP.NET site that periodically spawns a background thread to do some jobs. the thread's execution consists of a JobRunner that iterates through a list of IJobs and calls Execute() on each one. JobRunner and each IJob is created by NInject. A couple of the IJobs have a dependency to IRepository<Model...
I am using a backgroundworker that can have n instances. Problem is the DoWork method (that has the 'sender' parameter which is the BackgroundWorker) calls other code that produces a callback - thus i dont have the sender. How can i determine the BackgroundWorker that the current code is running under? ex: private void SetupThread(...
I've got a C++/CLI application which has a background thread. Every so often I'd like it to post it's results to the main GUI. I've read elsewhere on SO that MethodInvoker could work for this, but I'm struggling to convert the syntax from C# to C++: void UpdateProcessorTemperatures(array<float>^ temperatures) { MethodInv...
My backgroundWorker uses ReportProgress to update the ProgressPercentage of a long process. What happens is in two out of three entries into ProgressChanged ProgressPercentage is zero, whereas every third entry into ProgressChanged the ProgressPercentage is what I would expect. This happens like clockwork; it is very repeatable. Here ...

I'd like this task to be run from within the web app, so that my importer gets access to all the data classes, also it would be less complicated I...

Hi all, I'm trying to integrate quartz scheduler into a struts2 web app. Just wondering where you configure the jobs? I think the best place would be to put their details in the quartz.properties, but i cannot find the documentation that shows how to do this. All i can find is examples of how to programmatically create the jobs, but if...
I have a windows forms dialog, where a longer operation is running (asynchron) within a backgroundworker job. During this operation I want to change some values on the form (labels,...). But when the backgroundworker tries to change something on the form, I get the error "Cross-thread operation not valid"! How can this problem be solved ...
I'm creating a custom charting control and I would like to have the possibility of displaying some sort of wait bar while other commands are running (i.e. chart is being created). I'm using ProgressBar (System.Windows.Forms.ProgressBar in marquee mode) as a part of this control. I do not need to update the state of the progress bar, I ...
