Read What The Destination URL Is When A Redirect Is Requested?
Sep 25, 2009
I am using a MasterPage with a dynamic menu bar across the page. If the user has requested a redirect back to the login (home) page, I don't want to log them out but I do want to hide the menu bar. Currently I am using whether the user is authenticated to control if the menu bar is visible or not.Basically, I want to always hide the menu bar when on the login page.The menu is rendered prior to the page itself so I need to be able to read the redirect request to see if the login page is the destination.

how I can Encrypt the data that is requested/sent? I wrote an application that connects to MySQL to INSERT/UPDATE/READ information from/to. The application also connects to a website of mine. I have obfuscated the codes so that people can not simply de-compile it to see my information. However I, or anyone, can simple use Wireshark or Fiddler to see information like...
How can I encrypt that so i can at least feel a bit safer... the attacker can also use replay attack on my website until they get into a user's account...

I have a text file that has thousands upon thousands of URL's in it. I wrote a program to go to each of these links in succession (via For loops, obviously) and to grab a piece of information from them.Now to the problem. When I get to about 2300 or so, I get the error "COMException was unhandled by user code. The requested resource is in use. (Exception from HRESULT: 0x800700AA)" at the line "WebBrowser1.navigate(linkstocheck(i))"
I set linkstocheck = all lines of the text file. I get the same error even when I get the link directly from the lines of the text file. Does anyone know how I might go around this? Maybe catch the exception, wait half a second, then continue where it got the error?

I have a space ship that I want to turn to a destination angle. Currently it works like 90% of the time, but sometimes, it 'jumps' to the destination angle rather than moving smoothly. Here is my code:
a = System.Math.Sin(.destStoppingAngle + System.Math.PI)
b = System.Math.Cos(.destStoppingAngle + System.Math.PI)
c = System.Math.Sin(.msngFacing)
d = System.Math.Cos(.msngFacing)

I have created a web service with VB .NET 2005 that is connecting to a DB2 database through a third party ODBC driver of DataDirect and simply adds a row to the table.The service is working properly.Because I had to move the service to a server and the DataDirect driver that I have works only for client use, I needed to change the ODBC and use the DB2 Connect ODBC driver for the cause.

I have a datagridview on a form which is populated with data from our backend database. A few of my users are experiencing a problem when they select all the cells in the datagridview and try to copy and paste the contents into something such as Excel.
The error is: Requested Clipboard operation did not succeed.
Having searched for information on this error it appears that if a process has the clipboard already open (such as office) this will cause the exception being thrown (which is a system.runtime.interopservices.externalexception), usually when the code calls the clipboard.settext method (which I do not). However my form and its code does not even contain anything to do with clipboard manipulation, copy and paste or anything remotely to do with using the clipboard so I am unsure as how I can actually catch this exception and just report back to the user?

I am making a software in VB .NET and I wanted to find out where a packet is directed i.e whats its destination IP .ctually what I am doing is kind of a relay.. means for example - A computer(192.168.1.2) wants to send a data to 192.168.1.10:80 but I make it send the data to my server computer i.e 192.168.1.5 which then sends the data to the destination machine which 192.168.1.10:80 .So basically I want to find out where the packet wants to reach(in this case 92.168.1.10:80) . The structure looks like --Client Computer -> Destination Computer [ In normal case ]But I want to do something like this :- Client Computer -> Server Computer -> Destination computerFor the Server computer to send the data to destination computer I guess I will have to know where the packet wants to reach or something

Source code: vb.net
We are using File.Move() method to move the file from source to destination locaion. But the destination location is being monitored by one tool, whenever we are moving files to the destination location, it will pick up the file and process it. The issue here when we try to move huge volume file like around 5GB file, the tool is immediately picking up the file and try to process it before the move operation is complete and send failure notice to all the users.. After again successfully moving the file completely, it picks up the same and process it sucessfully this time and send successful notice this time.
We can't have control over the tool which is monitoring the destination folder because it is a third party tool. However we want to find out the alternative option to place a lock over the destination foler like ReadWrite access till the move operation completes so that 3rd party will not be able to pick up or try to access that file.

I'm trying to copy a file, using System.Copy. The destination, if it exists, should be overwritten. I had been using a single line of code for about a month, without problems : IO.File.Copy(SourceFile, DestFile, True)But problems started about a week ago, when I started more advanced checks. Partially locked files fail to copy, and the destination gets deleted. Locked files, on the other hand, work correctly: they just trigger a file in use exception.So I added this line before launching the copy:Using TestForAccess As New IO.FileStream(SourceFile, IO.FileMode.Open, IO. FileAccess. Read, IO.FileShare.None) : End Using..This was supposed to launch an error if the file was in use. But it is to sensitive. Some files (such as thunderbird's abook.mab) trigger an error in this added code, whereas they copied fine before (and you can copy them in explorer).My question basically is: How do I tell the system: copy source to destination if possible; if not, don't break destination?

I have 3 components, a managed .NET diagnostics app, which interfaces with a C++ multithreaded UDP socket messaging DLL, which sends messages to another C++ app.
Sometimes (especially on exiting the managed app) the messages are not getting properly handled by the destination app. The UDP socket DLL is sending everything fine, but they are not being handled on the recieving end. Now, if I put a messagebox in on the managed side, everything goes fine. Thinking it was just a delay thing with the popup, I've put thread sleep, regular sleep, timers, counting loops, etc. These "other" solutions do nothing, only the message box is making the messages be handled.

I'm transferring from one FTP (a Dev site) to another FTP (a Test site). Spare me the thoughts of changing this process. In any case, here's my method:
Public Function TransferFile(originalFile As String, destinationFile As String) As String
Try
'FileStream for holding the file
Dim uploadRequest As FtpWebRequest = WebRequest.Create(destinationFile)
uploadRequest.Method = WebRequestMethods.Ftp.UploadFile
[Code] .....
This works perfectly for ASPX files and their .vb code behinds. When we try to transfer .DLL files, they show up on the server as 0 bytes, and sometimes actually transfer. The problem is that, despite being the same size as the original, they act as if they are corrupt.

So I am using a user to run the following code that is a member of the "User" group on a Windows 7, x64 machine. I am trying to use impersonation (by logging in as a user that is part of the Administrator group) to allow the current user to read from the registry. For some reason the login happens successfully but even though WindowsIdentity.GetCurrent() is returning the user that is part of the Administrator group I am still getting an error message saying "Requested registry access is not allowed". What am I doing wrong? This is the main code:
