How To Show Actual Progress Of Data Transfer
Nov 21, 2009
When I move or copy files, I'd like to know how to show the actual progress of the data transfer.Something that I don't understand is how when moving or copying files to detect the actual progress of the data transfer. I always put the moving/copying in a background worker and that does fine, but presently I can only report status based on how many (of the total) files have been moved or copied.I've tried to look at the destination and my thinking was to report the progress based on the bytes there, but that doesn't work because it always sees it as being the complete file's size, even though that makes no sense.In fact, if you copy a file using Windows Explorer, it does the same thing, although obviously it's still transferring.

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 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?

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 know lots of you have had problems with the form designer giving errors and refusing to show the actual form, mostly because of some transition in software i take it (i aren't a Full time programmer, its just a hobby.)My problem is similar, vb refuses to show me my form and now i have even more problems.the last thing i did before this happened was try to add an imagebox to the form.Heres a few errors i get:every label i have is no longer declared?event 'load' cannot be found- My other problem is, i managed to close the designer window during this problem and i cant remember how to get it back up

Transfer
Public Sub DownloadFileBinary(ByVal localFile As String, ByVal downloadUrl As String)
Dim req As HttpWebRequest = DirectCast(WebRequest.Create(downloadUrl), HttpWebRequest)
req.Method = "GET"
Dim resp As HttpWebResponse = DirectCast(req.GetResponse(), HttpWebResponse)
' Retrieve response stream
[Code] .....
1. How can I create a progress bar that will indicate the status of the transfer?
2. If the remote path is not available, how can i easily alert the user that it is unavailable. Currently it returns an exception but it took a lot of time to return this message..

It seems that the autosize columns will only make them bigger. For example, if I have a DGV that fills most of the form and then only three small columns are loaded, there is a whole bunch of darkgrey empty space. Is there any way to snap the side of the DGV to the actual data?

on my Bookings program i've got a listbox where i can select the booking date of each room, and then i can see the details "UserID, time start time end etc". When the UserID is read from the database it takes the user id number (which its supposed to) but now i want to take that number, and match it to the actual "User Name" and then display the Name.this is what i've got so far;
Dim BookingDetails As New SqlCommand("SELECT UserID,......(and the rest)
then i execute the reader
Dim drBookingDetails As SqlDataReader = BookingDetails.ExecuteReader
and then i'd want to convert the read data, into the actual user name?

I want my program to copy a file or two from a folder in the directory of the program to a given directory. I also want a Progress Bar for this. I am not too great at this stuff, so I am not even completly sure where to start at to do this. Edit: Not sure if this is possible with VB, but is it possible to just Download it to a given directory instead and show a progress Bar?

I need help getting a progress bar to show percent in it. I want to have the percent in the middle of the progress bar, like is sometimes seen in a few programs. I have googled this, and can't find anything. I found something on The CodeProject, but it was just a label and drawing a rectangle behind it. I would like the actual progress bar that is available through the toolbox.

I'm trying to do a form while a background process is running. Similar to a progress bar but not a progress bar. We have a form that has an animated gif (customer request) and that's it. no other controls. They want this form to show while the processing in the background is running. I try to do this but when the progress form is shown the animated picture is not shown and a white blank space is shown instead of the animated pic. How can I do this? It looks like the BW would work, but i'm not understanding how.

I have wrote a program that do a bit of calculations that takes about 10 min to complete, therefore I need to show a progress to user. I used a percentage in status bar to show the current status of program.
The problem is for updating the number after each iteration I use me.refresh to show the percentage. BUT whenever the program lose the focus for example working on other stuffs, the program cannot update the percentage anymore. And above the form shows not responding but do the job until get the result.

I'm using the following to populate a listbox from a sql server:[code]Is Available returns true (It's a bit in sql) or false - Is it possible to replace this with something shorter, say a checkbox or tick image?Also, is it possible to only display actual data rather than the whole field including empty characters? I have a few nchar(30) fields, the above seems to include all 30 character spaces.

I am using the DownloadDataAysnc. But the ProgressChanged event doesn't show progress until after the data has been downloaded.Even when I try and download a data which is contained in a big file. The programs remains responsive so I know it is doing something.However, it is when the progress has completed that the progressChanged event fires.I known this as the progressChanged and the DownloadDataCompleted fire immediately after each other. However, they should be a pause as the file is quite big.This is the code snippet I am currently using. And the output below
Results:
Progress changed Version userstate: [ Version1 ]
progressBar1.Value [ 100 ]
