Return Progress From DLL?
May 26, 2009
I have written a dll in vb.net that does a lot of number crunching and iteration and takes about 2 1/2 minutes to complete, so I would like to make the progress available to the calling application.
At present I have created a couple of public variables in the dll called sngProgress and intIteration and update them in various loops in the dll.
In my calling applications I have a text box and a progess bar on a form but I cant see a logical way of updating them during the lifetime of the instance of the dll.
The call to the public fucnction in the dll cannot be in a loop otherwise it would be called multiple times so a doEvents call does not seem feasible.

I am trying to implement a BGW and want to report progress to a progress bar for my TextFieldParser program, sometimes if your opening very large files it takes a while and I would like the user to be able to see the progress and have some interaction so they know the program is still running I am a little hung up on what to in the reportprogress
I have:
worker.ReportProgress(0, myReader.ReadFields())
and its not doing anything, I didnt expect it too since ReadFields is an array
parser
Private Sub BackgroundWorker1_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork
Dim worker As System.ComponentModel.BackgroundWorker = DirectCast(sender, System.ComponentModel.BackgroundWorker)

I copied the code here and translate the code to vb [URL]it is working fine but there is one small problem but I cannot solve? Here is my code: SyncClientVB Another Source The scenario is... the progress is reported by an event (OnCopyingFile event)
Public Sub OnCopyingFile(ByVal sender As Object, ByVal e As CopyingFileEventArgs)
If pbFileTransfer.Value <> e.PercentCopied Then
If txtCurrentFile.Text <> e.FilePath Then
txtCurrentFile.Text = e.FilePath
[code]....
The problem is that it is ok when runned but when I click the form it starts to hang but in the console... it is still continuing.

I have two forms, when the user selects a button, the second form opens and an external executable begins an automated process. The point of the second form, is to only show the current progress of the automated tasks and closes when those tasks are completed.How would I use a progress bar to show the current progress of an action on a different form without knowing how long it will take?

frmMain - Allows user to pick process or combination of processes they want to run frmProcess - Shows progress of their selection I have three modules. Each runs a specific process. The frmMain allows the user to run any one of the three modules individually or all together in a single process (basically, runs the one after the other until done).

I have a filesystemwatcher which place files in a queue when they are created. From the queue the files are further processed (xml into SQL database).
The mechanism works fine, but I want to add a progress bar to follow the progress of the files in the queue: processing 1 of 10......2 of 10......3 of 10 etc.For testing, I created a batch file to simulate the creation of files, so the filesystemwatcher can to his work and place the files in the queue. When I tell the batchfile to simulate the creation of 20 files, I see that the amount of files in the queue change. For example;

In the app I'm currently making, I have two progress bars. One for current task being committed and the other is for overall progress.During runtime, I calculate how many tasks are being run and set that as the maximum. As each task completes, the progress bar is incremented by one.
I want the current task progress bar to show the progress of the current task. Some tasks can take a few minutes to complete so that progress bar works great. But, if the task is super quick, like editing registry keys, I see no progress at all.When I edit the registry, it basically goes like this:
'Edit Key
'x
'x
'x
ProgressBar1.PerformStep()[code].....
It completes so quickly that I never see the bar even move.I also have each task report its name into a label and it skips ahead so quickly that I only see the first task name and the last.Is there any way to make this do a better job at reporting the progress?

I came across a problem in my program it takes too long to calculate the values needed (about 10 sec) .But thats not the problem you don't know when the program is working or not, as it just locks up until its finshed and I view that as a problem.
I need to be able to show the progress of this .I looked at using background Workers but I get exception "Object reference not set to an instance" I believe this is because the background worker cannot write values or something ,As it works will a normal handler.

I'm working up a system where I plan on using RealProxy objects to enable intercepting method calls against a set of objects, handling the call, and then returning appropriate results. This works just find for simple return types like strings or ints, but I can't seem to return objects from the RealProxy.Invoke method. Everything works. I get no errors, but the returned value is always NOTHING, instead of an object.
I've worked up the smallest sample code I could, and have included it below. Essentially, just call RPtest and single step through. The code creates a simple object, RPTestA, with a string field and an object valued field It then retrieves the string

In order to return a value from a VB.NET function one can assign a value to the "Functions Name" or use "return value." I sometimes see these inter-mixed in the same function. Personally, I prefer the return. My question is, what is the internal difference, if any, between the two?

I'm working with the progress bar, doing manual tests for response I will be having some data streamed to the bar and it will need to adjust pretty dang quick.
Private Sub HScrollBar2_ValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles HScrollBar2.ValueChanged
ProgressBar1.Value = HScrollBar2.Value
End Sub
however when I randomly drag the scrollbar the progress bar lags 1/2 sec behind the scroll value. This used to not happen when I used the old .net 2.0 default blue scroll, but this is the glass style progress bar. Just need to know if I can speed up response time.
