Using The UploadFile Webclient Method?
Jun 3, 2010
I am trying to use the UploadFile WebClient method to a HTTP server which is operating on a device, however when I do this from my code at the client end (a PC), the server crashes. If I upload the same file from my browser on the PC to the same device running the same server, it works just fine. When I track the code on the web server there appears to be a difference in the header which is sent to the server. It is a 'Post', however the filename doesn't seem to be there. Is there anyway of reading the data that the UploadFile method sends?

I seem to remember reading the MSDN somewhere that there was another method to download files from URIs other than using the webclient object. I'm trying to download some raw php files but every time I use the webclient object the server interprets them as an HTTP request and instead serves the default web page that the php file builds and not the php code itself.

I'm getting a string response from a server using a simple call of the Webclient.DownloadString() method, the returned string is something like this:
"snakeu003Cbu003E eyesu003C/bu003E"
how can I convert that in whatever those codes means?

I am utlizing a piece of code for an FTP upload process that we want to occur when the check mark is checked, The download function (virtually same structure) works extremely well and without any issues. But the uploadfile function merely creates a file on the destination path called what it should be called, but does not upload any information. I think there is some uploadstream that I have to invoke which I am not. This is just the code starting at that process.
ftp.Method = System.Net.WebRequestMethods.Ftp.UploadFile
'If we were using a method that uploads data e.g. UploadFile
'we would open the ftp.GetRequestStream here an send the data

This code is put within a timer that executes every 3 seconds. ( instead of a while loop ) Whenever I run this code, the program takes time to upload the files in the folder to the ftp server, and it becomes (not responding), but it doesn't stop working, after the "not reponding" message, it reponds, but then it becomes not responding.. this is making the uploading process very Slow. I've heard so many things about application.doevents() and Threading and etc.

Dim LogonCred as net.credential= New Net.Credential(userid,password, domain)
Dim DestUri as Uri=New Uri(file://192.168.86.1/c$/Program Files/Test/Test.xml)
My.Computer.Network.UploadFile("d:Test.xml",DestURI,LogonCred,False,3500)
This passes credentials of my local machine (which is not part of the domain) instead of passing the LogonCred.Is this function just broken? Or is it my code?

I have a large problem with inheritance in vb.net. The problem is the following:
I have 2 forms => frmBase and frmChild
In frmBase i want to create a method Called StartWorking() and i want frmChild to inherit this method.
But here is the tricky thing: when frmChild.StartWorking is called i would like the following => without calling MyBase.StartWorking()
I want frmBase.StartWorking() to be executed first and after a test in frmBase.StartWorking if blnValue is true then frmChild.StartWorking has to be activated. if blnValue is false that frmChild.StartWorking cannot be activated.

I have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.

Write an overload for every numeric type or if possible constrain a generic extension method to just numeric types.

When I am loading an Assembly dynamically, then calling a method from it, I appear to be getting the method from Assembly executing before the code in the method that is calling it.It does not appear to be executing in a Serial manner as I would expect. Can anyone shine some light on why this might be happening. Below is some code to illustrate what I am seeing, the code from the some.dll assembly calls a method named PerformLookup. For testing I put a similar MessageBox type output with "PerformLookup Time: " as the text. What I end up seeing is:
First: "PerformLookup Time: 40:842"
Second: "initIndex Time: 45:873"

Why does my the declaration of my string in the code result in the following error? Is there a workaround?
Code:
<script runat="server">
Protected Sub form1_Load(sender As Object, e As System.EventArgs)
Dim x As String = "</script>"
[code]....
Error: Statement cannot appear within a method body. End of method assumed.
Note: The following page did not fix my issue and instead resulted in the string </script> being output in my page. ( VB.NET hates </script> tag in string literal )

I would like the VB.net WebClient to remember cookies.
I have searched and tried numerous overloads classes.
I want to login to a website via POST, then POST to another page and get its contents whilst still retaining my session.
Is this possible with VB.net without using WebBrowser control ?
I tried Chilkat.HTTP and it works, but I want to use .Net libraries.

as per usual i am a little confused. I know DownloadStringAsync runs on a threaded pool with a default min and max threads limit, but what confuses is how would i call DownloadStringAsync say for example ten times.Example.I have an array with 10 URLS. Surely i would not use a for each loop of the array index to pass the url address while each time calling DownloadStringAsync(New Uri("someArray(index)") surely we can pass say a range of items from the array and let DownloadStringAsync decide on the threaded pool how many to process each time?

Using the following VB.Net simple code to upload files in FTP, a call to WebClient.CancelAsync() doesn't actually cancel the upload.Does someone know why, and what can be done about this?
Private Sub UploadProgressChanged(ByVal sender As Object, ByVal e As System.Net.UploadProgressChangedEventArgs)
'TO-DO: Why is pbar empty?
ProgressBar1.Value = e.ProgressPercentage
Label1.Text = e.BytesSent & " bytes sent"
