• .NET Development Block packet by packet payload

  I want to create a packet filtering but not use IP as the filter, but the packet payload as the filter. For example I want to block user that request mp3. So I only watch the payload if there any request of mp3 then that packet is dropped. Now the problem is how to make the packet route, that must past our application for payload check then after check passed than the packet can passed to network adapter. Its like that packet route is serial, go to our application first then to adapter, not like this the packet at the same time go to our application and also pass the adapter. Thanks. This is very much a kern ...Show All

• Visual C++ Multithreading

  Is it possible for a master thread to force abortion of pending IO in a slave thread, as with signals on Posix. Win32 only, no .net bullshit please. Thanks, - NK A similar way has been suggested by Ronald in this thread. Unfortunately I cannot guarantee (or rather enforce) that the client code is using asynch IO. Hence this is not the solution to the problem. With posix I can use signals to abort *any* system call, including the blocking ones. I was hoping that a similar solution could be found with Win32, alas, it appears there is none. Thanks, - NK PS. the library I describe has already been implemen ...Show All

• .NET Development Single p2p? Send files using sockets or remoting?

   I just did my first single application with remoting and I liked it. Should I use remoting or sockets programming If I should use sockets can you please point me to the right information of sending files and everything I could need Thanks For your first question, it really depends on transfer sizes and number of conneced clients, available bandwidth etc. For example, if you're got dialup users you will want every last byte you can squeeze out of the network connection, and so you will want to go the sockets route and implement a very light transfer protocol (e.g. implement a syn/ack with a crc32 on small 2k packets). However, if ...Show All

• Visual Studio Team System How do I use multiple rows per test?

• Windows Forms Windows Installer Uninstaller and Conditions

  Hello, I have two problems. I created a new windows setup project in VC2005 Pro. There I added a checkbox page with two checkboxes. One to create a shortcut on user's desktop and one to create a shortcut in user's program menu. My problem is, that the installer always creates both shortcuts regardless of the state of the checkboxes (CHECKBOXA1 and CHECKBOXA2). I added a folder condition to "User's desktop" and "User's program menu". What does VC expect there (CHECKBOXA1 or CHECKBOXA1 = Checked or ...) Another question is about an uninstaller. Is it possible to create an unistaller shortcurt, too Currently it is only possi ...Show All

• SQL Server problem with dynamically created RDL files and reports

  Hello, I have a strange problem with a dynamic created RDL resp. dynamic created report. I have followed the programming tipps on the microsoft site to create programmatically a RDL file and this RDL file is accepted by the reporting server. But when the report is rendered out of that RDL some fields are somehow modified. In one field after the first line (which holds the correct value) all values in the following rows are cut after the fifth character. Other fields contain every now and then strange signs like a caret... My report items in the RDL e.g. look like this: - <TableCell> - <ReportItems> - <Textbox Name= ...Show All

• SQL Server Import flat file automatically?

  Hi, I'm going to be getting several flat files that need to be imported into one of two tables. Although the text files will have different file names, they will have either "Header" or "Detail" in the file name, so I can tell which table they need to be imported into. The problem is I don't know enough about SQL Server 2005 to set up an automated import of these files into the database. Does anyone have any suggestions on how to do this, or have any experience in setting this up Are there any inexpensive programs to load data realtime or on a schedule (I work for a young company with a very tight budget).
