Hi there!
Fisrt the question: there is a ay to make the DownloadData when I want?
I have a WebClient class
I use myWebClient.Dow nloadData(remot eUrl) to connect to internet server
All this in a separate thread for asincron pourpose
Anyway, when I try to close the application before DownloadData returned, it
wont stop this thread.
The thread run untill a bool variable is set..but if the thread is not on
Reset state I cant send the Set call, or, even if I call it, the Reset is
next
this is the running function for the thread:
Private Sub start()
Do While True
paused.WaitOne( ) 'wait on the pause event...
If isCancelled = True Then Exit Do
Try
Dim datas, sData As Byte()
Dim strData As String
'sData = getBytes()
SetHeaders()
datas = wbclient.Downlo adData(SERVER_A DDRESS)
'datas = wbclient.Upload Data(SERVER_ADD RESS, sData) ' signal
back to the caller that we're done...
strData = Encoding.ASCII. GetString(datas )
Dim responseHeaders As New WebHeaderCollec tion
responseHeaders = wbclient.Header s()
onResponse.Invo ke(datas)
paused.Reset() ' pause the thread...
Catch ex As WebException
onResponseError .Invoke(ex.Mess age)
paused.Reset() ' pause the thread...
End Try
Loop
End Sub 4 3697
Hi Crirus,
I did not look very in detail to your code, but I have the download in a
seperate thread and "abort" that thread in the situation, I thought, you did
describe and I thought it works (I never know with the webclient)..
Cor
I use a reset/set system to sleep the thread and a while loop.
As long as Cancel is false, the thread remain in while and sleep or run...
If I make Cancel=false then the while exit and the thread finish.
So, the ideea is that when the thread running routine wait for data in that
method, if I try to cancel the thread he is allredy running so no Cancel is
tested

Hi Crirus,
That I did test to, all other methods, keep the thread alive, only the
abort did give me a solution. (It kills it in a way, but a thread is never
killed really direct by your program as far as I know, but it stops
downloading, I told I am not sure, but that is only a very little bit).
Cor
Solved...when DownloadData return I just kill the thread if Cancel is
true...usualy that delay hapend when webClient cant find the host

Hello group,
I was wondering if anyone here could help me with an odd WebClient
problem. When I run the following code:
WebClient aWebClient = new WebClient();
Byte aBA = aWebClient.DownloadData("http://www.microsoft.com");
string strContent = Encoding.ASCII.GetString(aBA);
Everything works as expected. However, when I run the following code:

I am using WebClient to download a text file from the net every 2 minutes.
The problem is that I think I am reading the file from cache since when the
file is change I still get the old file.
Here is my code:
Dim myWebClient As New WebClient()
Dim responseArray As Byte() = myWebClient.DownloadData(szURL)
How can I tell WebClient not to use cache ?
Thanks in advance

Why does WebClient.DownloadFile loose my completed path?
Ok, I have a function in my app then when my button is clicked it checks to

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
