View 2 RepliesI 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

View 13 RepliesI'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?

View 3 RepliesI'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.
View 10 RepliesI have an application that uses SendMessage to send a list of numbers one at a time to a query window in the database we use. The problem is that when SendMessage fills the textbox, then clicks "Query" (hWndQuery) my application freezes up until the query is finished running, which sometimes can take up to 20 minutes depending on the query. Any way to force the program to be responsive after it 'clicks' the query button?
Below is my code - I commented where the program freezes (15 lines up from the bottom):Private Sub Query()
Dim hWndQQ, hWndTextBox, hWndQuery, i, iResult As Integer
Dim sTemp As String
sTemp = ""

My mate & Myself are currently building a IRC Client, a problem we have come across is when opening a chatroom the form Freezes for example.
We are currently using arrays so we can open multiple chat rooms and at this current time to open a chat room we use
Channels(ChatIndex).Show()
The form opens but freezes.
I have also tried using
Channels(ChatIndex).ShowDialog()
Application.DoEvents()
Using the above code, the form does not freeze but appears we can not access any of the controls such as (RTB)
What would be causing the form to freeze on .show(), Has anyone else had any similar issues?
Of course, it's nice enough to unfreeze itself when the task is completed. I have must at looked at this code for 2 hours, and still can't find the bug.

I have a program that has multiple tabs, with roughly 100 - 400 controls of varying types on each area. The program takes about...4 seconds to load, which I don't think is right.I did a few memory tests on the program startup, and idling it. At startup, the program uses 100% CPU usage, and 102mb of RAM, but then the form displays, the RAM drops to 20%, and CPU at 0%.Changing a Tab locks the program up for 1 to 2 seconds depending on the tab, and memory fluctuates.Am I doing something wrong here, when a program form has literally over 500 controls of many types, spanning 6 tab pages, or should I be doing something different?

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 _

"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.
