View 10 RepliesI'm trying out uploading of files from local computer to a server and I'm using these few lines of code:
My.Computer.Network.UploadFile("C:Temp est.mp3", "192.168.1.2 est", "", "", True, 500)
This does exactly that and the "True" in the above string shows a progressbar in its own window. I would like for that progressbar to display on the same form as the rest of controls are. And not in it's own window. Is there a way of doing just that?

I am trying to upload and download a file to a ftp server with progress. I have already went through multiple articles and sample code but was not able to complete this task.
View 11 RepliesI'm using the code below to send text messages, but sometimes I need to send a large text file (500kB - 1,5MB) and I'd like to show the progress.The only way this can be done is by sending the data in smaller parts (I think), but how can I do this properly? BeginWrite is asynchronous and won't wait until a previous part has been uploaded, so tracking the upload progress is not accurate.
Is there also a way to limit the upload speed, lets say to 25 kB/s?

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 The problem I am getting though, is when the version is outdated, the file will go to download the new .exe and it gets and error saying "File already exists"

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.

I'm trying to save this picture from a website automatically, but the problem is there is no file extension. I tried the following code, but it always gives me an error:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
My.Computer.Network.DownloadFile("http://www.hackthissite.org/missions/prog/2/PNG/", "C:PNG.bmp")
End Sub
Error: An exception occurred during a WebClient request.
P.S - I believe the reason it doesn't have an extension is because the picture changes each time the url is loaded (probably through a php code). I'm not too sure on the specifics, but the lack of an extension is what I am having problems with.
VS 2008 SP1 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
AddHandler client.DownloadFileCompleted, AddressOf client_DownloadFileCompleted
