• .NET Development Load Balancing Socket Connections

  Hi, I don't know if this is even possible but here is the scenario I have: I have a server/client application connected via TCP.  Lets say I have 5 clients applications.  I have 2 server applications running behind a load balancer.  Since it's TCP, lets say 2 of the clients make a socket connection to server 1 and 3 of the clients make a socket connection to server 2.  Can I have server 1 send a message over the socket connection to each of the clients   The clients make the connection to the server...so I can't just open another socket connection from the server to the clients... Make sense Is that possible ...Show All

• Windows Forms Click once and trust license

  hi, In beta  you could programatically install trust licences (there was a .net function and even a sample called trustlicensedeployment.). In beta2 these functions seem to have been removed and the sample also. Can anyone tell me why and what is now the best way to deploy such a trusted license to all workstations Also is there a list of changes between beta1 and beta 2 thanks, Bruno Hi, TrustLicense Deployment feature is cut in Beta2 and going forward. While there are some advantages with trust license, like it allows delegation, there are other cons like complex model, poor tool support, no revoca ...Show All

• .NET Development stopping connections

  Hi. I've done this before but for some reason I cannot figure where I am going wrong. When I start listening to a port, I want to stop listening to it, even if there are no connections. When listening, it is listening in another thread. I have 2 buttons, Start service, and stop service:   Start Service: Creates a new thread, and it runs the method to Listen to the communication Starts this thread   Stop Service: if the Socket Client is non null, then it stops the client tcp listener. null's the client socket. //this is where the exception is thrown straight away "A blocking operation was interrupted by ...Show All

  Why I can't send messages to Pocket PC emulator application which has TCP listener binded to host adress:"127.0.0.1" from desktop application which has TCP client which try to connect to the same adress I' m receiving error 10061. I'm using VS2005. Error 10061 is Connection refused . it's mean no connection could be made because the target machine actively refused it. This usually results from trying to connect to a service that is inactive on the foreign host (your machine in this case). maybe that the server application you're trying to contact isn't executing ...Show All

  I have runnning and perfectly working SoapExtension project in the web application solution. The WebServices servers are a "BlackBox" to me. I'm trying to: 1.

• Visual Studio Team System string.Empty and ""

• Visual Basic Form Switching

  Hello all, I know this is a real n00b question, but I was wondering if someone could advise me as to a better way of doing my form switching without creating a new instance of a form each time. I know usually you can just go Dim F as new Form2 F.Show But that creates a new instance of Form2. What I'm trying to do is to have a permanently open version of Form2 that I can access at any time. The reason I want to do this is so that I can keep all the information stored on that form (text box contents, etc) available for use later if the form is closed and re-opened again. I found a method to do this, which was to create a module and ...Show All

• Windows Forms list box tooltip?

  Hi. Is it possible on a WinForm C# application to have a tooltip appear under the mouse cursor when you hover over an item in a listbox I am using .NET 2.0 Yes you can but it requires a little bit more work than using something like a ListView.  You'll first need to drop a ToolTip component onto the parent form.  This gives your ListBox tool tip capability.  Then you'll need to trap the MouseMove event on your list box.  Whenever this event occurs you should get the index of the item at the current position of the mouse.  If you get an item then you can use whatever logic is appropriate to determine the tool t ...Show All
