I hve threaded ftp download, and that thread reports it's progressto another form (to progress bar). Now, when thread downloads, progress of thread is much slower than actual download is, so for instance: all files get downloaded, but the progressbar is at 50% or even less. Is there a way to track the progress of actual FTP download.
View 7 RepliesWould anyone be able to help me here please. I'm fairly new to VB.net and threading so im just trying to figure out what is happening.When I debug this I am getting the error thread operation not valid: Control 'ProgressBar1' accessed from a thread other than the thread it was created on.
I'm a little lost as to why the error is occuring or how to fix it. I've had to put the progress bar in a separate thread otherwise the GUI crashes

I have a windows application with a main form, on which a user control is added dynamically when a device connects trough USB.
On a user control, there is a thread wich is getting data from the device trough USB and when it is finished, I want to change a progressbar that is located on the main windows form where user control reside.
This is the code that is I call on the user control thread to change the progress bar value:
Frm_Main.UpdateProgressBar(CInt((AllBytesReceived / MaxBytesInFlash) * 100))
and this is a code that is called on the main form:
Private Delegate Sub UpdateProgressBarDelegate(ByVal value As Integer)

Ok i have a progress bar that increases when a download starts to finish. The once its compleate the next part of the script starts.
After all the script has finished, around 30 seconds. It starts the full process again but atm it wont start again as the progressbar is still complete.
I have tryed adding
ProgressBar1.Value = 0
To the end of the script to set its value back befor the script starts again but that dont work either :/
How would i get the progress bar to go back to its orginal state so that it can start all over again.

Dim Gimagepath As String
Gimagepath = System.IO.Directory.GetCurrentDirectory() + "udimage.jpg"

Preface: I know this is an unusual/improper way to do this. I can do this with a "real" ShowDialog(), background worker/thread, and so on. I am trying to do specifically what I describe here, even if it is ugly. If this is impossible for X reason, I have created a fancy progress dialog for some of our long running operations. I need to have this dialog shown on a new thread while having processing continue on the calling (UI in most cases) thread.

View 9 RepliesApparently Crystal Reports doesn't come with VS 2010 Ultimate like I thought it did. When I went to create a new report, I got prompted to download it free and install it. Then, after installing it, I tried to recreate a report and got the same prompt to download it again.

How come I don't get a "Done!" when it's finished downloading the file? (The file is only ~100kb.)
[Code] How i think that this should work: 1. Getting the size of the file that we want to download and updating the progressbar max value to that 2. Downloading the file and updating the progress-bar based on how much data its downloaded.

I am creating reports in Crystal Reports that is integrated within Visual Studio 2008, and I noticed that some of the features are disabled. One is the ability to link tables with a Right Outer Join or Full Outer Join. I also cannot "Show SQL Query" in Crystal Reports. Is this something I can enable or do I have to purchase or upgrade?
View 1 RepliesI've made an application which goes through a long procedure when a button is clicked. I don't want the user to think the program has frozen, so I'd like to add a marquee progress bar just to show that it's still running. However, if I simply add the progress bar and make it visible when the button is clicked, the bar will appear but freeze and wait for the procedure to finish before it starts scrolling.
I know this is due to both the procedure and the progress bar running on the same thread, but the tutorials I've seen on getting a process to run on another thread seem confusing. What is the simple way to make a progress bar run on a separate thread?

I created a software which download files from the web. I also added a progress bar which shows the download progress. Every thing works fine.
Now:
- How can I add a label that will calculate the time left for the file to be downloaded and another label that will tell the speed of the download?
- Would it also be possible to add a label which calculates the size of the file that is begin downloaded?
Here is what I declared:
Imports System.Net
Public Class Form1
Dim WithEvents Download As New WebClient
Dim WithEvents Download1 As New WebClient
Friend WithEvents Label1 As System.Windows.Forms.Label
Here is what I have under the download button:
Download.DownloadFileAsync(New Uri("URL" & ComboBox1.Text & ".rar"), Textbox1.Text & "" & ComboBox1.Text & ".rar")
And here is what I have under Download_DownloadProgressChanged:
ProgressBar1.Value = e.ProgressPercentage
Label1.Text = e.ProgressPercentage & "%"
If ProgressBar1.Value = 100 Then
MsgBox("Download Completed!", vbInformation, "Info")
Label1.Text = "0%"
I need to download an .exe from the web/ftp server and execute it. (it's a setup program)The application would use the WebClient (probably) class to downlad the files, and presumably would display progress to the user as it goes.

View 1 RepliesI have searched the forum and found several forums related to the backgroundworker thread but have been unsuccessful in finding my answer.My objective is to display an animated gif or progress bar while the program is executing a particular method which can take upwards of several minutes to complete. I cannot get the second thread to run the progress bar while the main progrem is executing the time consuming method. I have created a demo based on another thread and can't seem to get it to create two threads. I was attempting to get the backgroundworker to execute the progress bar while my main code runs on UI thread.
