VS 2008 Wait For File To Finish Downloading
Apr 4, 2010
I'm downloading a file asynchronously so that it doesn't stall the UI. I'm using a very basic WebClient and calling .DownloadFileAsync.The file I'm downloading is required for additional tasks after it has been downloaded. The issue that I'm running into is that, since the file is being downloaded on another thread, execution on the main thread continues while the file hasn't finished downloading.Is there any way to pause execution while the file is being downloaded? Or is there a better method?

I've made a gui for a cmd line program and I need to wait for the cmd line program to finish running before continuing.nd I have some code that starts the cmd line program and then calls a subroutine when it's finished running. But this method won't work since now I'm trying to run the cmd line program in a loop.Edit:Is there a way to just have the runtsmod subroutine (shown below) wait until the cmd line program is finished, instead of relying upon a subroutine starting when the cmd lineprogram finishes. This would simplify things greatly being able to call the sub tha starts the cmd line program and having it finish when the cmd line program is done.
Sub runtsmod()
'If the tsmod program exists in the directory the GUI is run from it is ran
Dim tsmod As String = Application.StartupPath & " smod_GUI.exe"

I need to get the url of the webpage the webbrowser is navigating to, but since the code executes faster than the webbrowser navigates to the webpage, it gets the url of the last page. I cant use DocumentComplete Event because i have a tabbed browser,
and i cant write events because im creating tabs(with webbrowsers) at run-time. So how would i check to see if the webbrowser has loaded a document?

I am using the FilesystemWatcher to look for files in a Directory, it does not matter what the file is. After a file appears it starts my ftp process and I end up with a bunch of 0 byte files because it processed before all the files arrived.
I would like to WaitFor... (Files_Created) to finish but dont seem to have the right syntax to get this to work properly. I have working code up until it loops. As you can see I have tried various processes to get it to work... mostly commented out. I also have imported just about everything trying to get this to work. Please ask away.
Imports System Imports System.IO.File Imports System.IO Imports System.Threading Imports System.Collections Imports System.Collections.Specialized Imports System.Diagnostics Public Class FileSystemMonitor Public Shared Sub Main() Dim fsw As New FileSystemWatcher() ' create an object of FileSystemWatcher ' set properties of FileSystemWatcher object

I am using the web client to download a file. Which works ok.
However, now I have to download many and the number of files to download will change everyday.
I am not sure how I can get the web client to know which files have been downloaded or not? I was thinking of using a for loop to download each file. But I will never know how many there are to download?
The web client could download the same file twice?
Private Sub btnStartDownload_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim client As New WebClient()
AddHandler client.DownloadProgressChanged, AddressOf client_DownloadProgressChanged

I'm downloading a file from my website using WebClient.DownloadFile(),I'm wanting to do it asynchronously, so my UI stays responsive, that would require me creating an array of web clients, is that bad practice? Or is it acceptable?I have looked into FileWebRequest, but thought WebClient looked easier to implement.

In my DoWork() function I register with our sip server. Then I have to wait for a response back. However, the response I get is received in another event. However, before I am able to check the flag in the DoWork() the DoWork() has all ready finished and the response comes after.
I am trying to find a way to wait in the DoWork() until I get a response in the Diagnotic event. I have a global flag that is set in that event that I have to check in the DoWork().I was thinking of maybe blocking in the DoWork() until the other event is finished. Maybe using a join.
' Do work in background worker
'Will return less than 8 if there are no error message from the library
If (Not Me.bgwProcessLogin.CancellationPending) Then
' Register and wait for response

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"

I am trying to download a file off my web server (easy) but the file its downloading is the updated version of the file running. I finally was able to program my automatic update software the program simply downloads a .txt file from my web server, reads it, and if the the version = (new version here) then download. If not, then go to another form. The problem I am getting though, is when the version is outdated, the file will go to download the new .exe and it gets and error saying "File already exists"

While navigating to a series of sites at one site the WebBrowser control's DocumentCompleted EVENT is tripped and no other recorded Browser events occur after that. When this happens the hour glass cursor indicates the browser is waiting. From this point it take 120 to 250 seconds of wall clock time before the browser resumes. I am looking for a way to force an abnormal termination without destroying the control. I have tried "Stop", "nav to about:blank" repeatedly without success. How can I force an abnormal termination when the Cntrl is in a wait state?
Consider the following: The last known Browser event to be tripped is a Document Complete event; nothing else occurs after this. When this transpires the Cntrl is waiting.
1:50:657: ============================= ENTER WebBrowser1_DocumentCompleted EVENT ========================================

I've got a code in VB that will download a txt file from a website. The problem is I want this file to be downloaded into whatever folder that my program is in. for example, if my program was in C:
andom_folder then I would want this txt file downloaded to C:
andom_folder
Here is some of my
My.Computer.Network.DownloadFile _
("http://www.mywebsite.com/test.txt", _
"define where file should go here")
But in the spot to put where to place the file, I can't just put C:andom_folder because individual users may have this program installed in other parts of there computer.
