View 4 RepliesI have been doing some research to determine an efficient and secure way to pass a document located on another server in the network to our web server and then on to the intranet user that requested it. While I have found plenty of ways to do this, I am not that experienced with this scenario as I have always just served documents stored locally on the web server and located nowhere else.
Our document server is shared in the domain and everyone has access to it and depending on their permissions, can access many files. I was thinking that I could possibly grab a file if I could pass the intranet users credentials but I don't know where to look to do that.
I was also thinking that maybe a webservice could do what I need but that just doesn't seem right to me because I am kinda guessing that there is already a .net library available that already handles something like this but am unsure as to what it is.

We are opening a Word document from our Visual Basic 2010 application using the Word object. When we run our application under Windows Server 2008 the document name is truncated in the main window title for the document. This is not the case when we run our application under Windows XP. Is there a way to prevent this truncation under Windows Server 2008?Mary Leathem
View 3 RepliesI 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?
How do i do that ? I want to wait until the webbrowser has loaded the document and then add the document text to a textbox... How do I do that ?

View 12 RepliesI've been trying to get this to work for days now, but I fail I have a very small HTTP Web Server using TCP sockets listening on port 80. I can connect and display html to the browser, parse GET parameters; but what I can't get is getting POST data. When I get a POST request, the headers and everything else come in fine, but the POST data is missing:
[Code]...
How can I send a POST HTTP request to a server (in Visual Basic 2010) and then receive the reply into a string.
View 1 RepliesI am using Async socket class to handle HTTP data. The OnRecieve event handler looks like this:
Private Sub sck_onDataArrival(ByVal sData() As Byte, ByVal BytesTotal As Integer) Handles sck.onDataArrival
Try
Dim ms As New IO.MemoryStream(sData)
Dim returnImage As Image = Image.FromStream(ms)
Picturebox1.Image = returnImage
Catch ex As Exception
Debug.Print(ex.ToString)
End Try
End Sub
I realize this will not work because the byte array still contains the header information from the response from the server. How to strip this data without converting the byte array to a string. I need to strip the header response information and just be left with the image data and from there convert that data into a stream so the stream can be loaded into an image and displayed in my picturebox.
I have created a few months ago a simple tool in vb.net, that sends an xml code to server, and that server sends response after a while. Everything is performed in http session, for that purpose I use webbrowser control and webclient. I know it could have been solved in different way, however iam not an expert in vb.net, and also didnt want to spend too much time on it. Anyway it worked, until they had changed something on the server. Let me explain in a few words how that tool works, so it will be easier to understand the problem.
In the first part, I open an URL in the webbrowser control, subsequently I enter xml code in the textarea on that page and click on the submit button. In result of that I get another page with some data on it, namely links to xls files. In the next part I use webclient for downloading those files. What is important for all of these operations I need to use the same http session id.
So, simply by now, i just set headers in webclient - WebClient.Headers.Add("Cookie", WebBrowser1.Document.Cookie.ToString) What have guaranteed to use the same session id by the WebClient. However, after the change made on the server mentioned before, the JSESSIONID value is not available in that string. When I use https analyzer (fiddler), I can see that value there...until moment when I am using WebClient. Of course due to that fact, the webclient won't download files for me, because the session id is not the same.
There is one more thing, what would be useful. When I checked the cookies file on my harddrive, I saw that line starts like #HTTP_ONLY. I think that would cause that problem with jsessionid.
Now, I am coming to my question Do you have any idea, how I would get that JSESSIONID value ? It is sent from webbrowser control, however don't know how to get it.

I have written server code in vb.Net. I want it to read to variables sent by another server's HTTP 'GET' request. For example the first server will send this URL [URL]msgid=$messageid where the values to be used by my server are sender, receiver, msgdata, recvtime and msgid I have written my code but it only reads the address sent by the http server and locates for the file in the server's root directory.

I have a vb.net program using the MS SQL 2005 Database.I use the SqlClient.SQLdataAdaptor to insert the records in DB.Whenever i load the program and then use the SqlClient.SQLdataAdaptor to insert record into DB for the 1st time, it will take longer time to load. But if I use the same SqlClient. SQLdataAdaptor to insert record into DB again immidately, it will take shorter time to load. However, if I wait for 5-10mins, then use the same SqlClient.SQLdataAdaptor to insert record into DB again, it will take longer time to load again.Can anyone tell me this loading is due to the SQL Server itself / the VB.net?Can anyone suggest me a way to check the reason of this loading?
