I have made 2 application server/client. I want to remote the client from server for example if I press 1 then one action should happen in client, if 2 then another action should occur. How can I do it? I think I should use select statment
Select case a' a dim as integer
case Keys.1
frmmain.axwindowsMediaPlayer1.ctlcontrol.play()
end select
is this right ?

View 3 RepliesI have to connect same type of remote objects on different destination using .net remoting. For example, I have a database access middle layer on a remote server and local server. But both are same type object. but the remote destination addresses are different. So how to connect it using .NET Remoting?
View 1 RepliesAnyone has a quick and dirty sample coding to making this work? Currently, I have server, client with Interface object as intermediate object between the 2. If I declare events in the Interface, then Dim object on client side with "WithEvents", I'll get error when I reach this line:
vb
serverObj = CType(Activator.GetObject(GetType(InterfaceObj), szURI), GetType(InterfaceObj)

View 1 RepliesI have a large class that I built to act as a TCP server for one of my silverlight applications. When a user connects it stores the tcp client into a table for later communication. The problem is that when I send data, with more than one client connected, it loops through both open TCP Clients but some how sends the data twice to the same client.... the other tcp client never receives his data. This isn't a logic issue as I can step through the code and see that it is clearly taking each individual TCP client out of the table and sending it the data. They all use the same port... could that be the issue? And if so how do I make it so that it can connect on one port then transfer to another? I have tried using different computers for connecting but still the most recently connected client receives all of the packets of data.
View 6 RepliesI'm new to VB and Windows programming but I do have a fair amount of experience programming at the command line level. A friend is having problems with his laptop. He does a lot of speaking engagements with Powerpoint. His laptop uses the F7 key to toggle the output to his external monitor port to the video projector. The F7 key has stopped doing this. Is there a way to create a Windows program that will do this without using a DOS window? He is not familiar with command line processing and needs something that he can double-click.
View 2 RepliesI have been struggling to find a solution for this problem. What I need to do is build a server application that accepts tcp client requests from different clients running on same port say:1003. I experimented by using asynchronous mode call backs etc. but it disconnects once connection is established and does not respond for further requests from the same client.

We are creating a Who wants to be a millionaire style game in VB. Our server is pulling information such as questions and answers from a Access Database and sending them to the contestants (Clients). All transfer of information is directly from the server to each client. One of the "Life Lines" we want to use is "Ask a friend", where one client is able to Instant message another client for a short time to get help on the question.

View 3 RepliesI currently had a .Net Remoting Application running on Framework 2 under IIS. I have to upgrade it to Framework 4 in order to use some new components. I have been able to set everything up and running smootly on Framework 2, but as soon as I change to Framework 4, I get the following exception when I try to call one of the function of my remote object.
The input stream is not a valid binary format. The starting contents (in bytes) are: 53-79-73-74-65-6D-2E-52-75-6E-74-69-6D-65-2E-52-65
This bug is not the real bug, it is caused by the fact that the remote object is throwing an exception, and IIS wrap the exception in XML, which throws the BinaryFormatter off.See this for more info on the bug.
This is very unfortunate because I cannot see what is causing the exception, and having never used any Remoting before, I do not have much ideas as to where to start debugging. It seems the Exception is thrown before even stepping in the code because I do a fair amount of logging and none of it seems to be triggering.Basically, I'm looking for some clues or pointer from people that encountered similar problems:
What could be causing the exception when no code has changed besides Compiling from .Net 2 to .Net 4?How can I get the full Exception message that is returned?

4.Close the Add Table dialog box.
5.Drag the CustomerID column from the Customers table onto the Orders table.
6.Verify that the Customers table is the Primary key table and the Orders table is the Foreign key table, and verify that the CustomerID column is selected for both tables.
7.Click OK to close the Tables and Columns dialog box.

I have a website that i've been working on for about a year now.Recently, it's started throwing System.AccessViolationException every now and then, in my dev machine, mostly, when I was away from the machine.I haven't changed anything on the server code in weeks, since I've been working 100% on the Javascript part, and this error started appearing recently.
Also, the code I'm doing is 100% managed. I'm not doing any interop, calling strange DLLs, nothing. It's pure VB.Net, so I don't see how I could be generating one of these myself.Now, I've been using this new machine for a couple of months, and it's not working 100% right. Every 2 or 3 days I'm getting a blue screen for example. I haven't had time to diagnose it properly, but I'm suspecting I may have a faulty RAM chip.

I have downloaded an application that uses .net remoting.
The problem is that I don't know how to configure it to communicate over the internet.
From the blog [url] says to set the tcp 192.168.1.100 . As far as I know this is the intranet IP. My external IP is different. Do I need a server or a Static IP from my provider?
