Remoting loses subscription but not proxy John Whitmire1-Aug-07 5:59 John Whitmire 1-Aug-07 5:59  The scenario: 1. Windows service, running on 2 machines; each marshals a singleton remoting object. 2. Events are passed thru an intermediary per recommendations in articles on Remoting Events. 3. Client, running on one of the 2 machines, connects to both services via remoting (TCP) and receives events from both. 4. Then... the LAN is physically disconnected from the client machine. 5. Loss of connection to the "other" machine is correctly noted and handled. Reconnection of the LAN cable results in correct recovery of that remoting connection. No problem there. 6. Problem: The next event delivery from the "local" service fails with "The connection was forcibly closed..." (Why, pray tell?) and the event delegate is appropriately removed (it's an expected result when the client "leaves"). The remoting proxy to the local service remains intact, so the client never knows that its event subscription has been lost and it never gets restored. 7. Oddity: If the LAN cable is unplugged before the client attempts the remoting connections, the resulting subscription to the local server events is unaffected by subsequent LAN connections and disconnections! Obviously, something about the remoting path is different. Q1: Can I force the insulated connection that occurs in (7) to happen even when the LAN is present? Q2: Failing Q1, can I detect or prevent the loss of the event connection that occurs in (6)? (C# explanations preferred) Re: Remoting loses subscription but not proxy John Whitmire2-Nov-07 4:16 John Whitmire 2-Nov-07 4:16  RESOLVED: The solution is to use IPC on the local machine for both directions--the proxy and the callbacks. When doing so, though, the IPC channel for callbacks has to be hidden from the marshaling on remote machines. See http://www.microsoft.com/communities/newsgroups/en-us/default.aspx?dg=microsoft.public.dotnet.framework.remoting&mid=f5d1bb8b-2fa8-4347-82f0-12957a8f9776[^] for more detail.

Then add all your files to the folder. Then right click on the folder and select add existing, then select the files you just added to the folder. Just make sure you let Visual studio 2005 create the folder. Hope that helps.

So, is there is any way we can provide a ".ico" file to the "System.Windows.Forms.Cursor" constructor in a Stream? Re: .ico to .cur conversion in stream object Dave Kreskowiak30-Jul-07 9:28 Dave Kreskowiak 30-Jul-07 9:28  No, not really. The problem is that there is information missing from an icon file that is needed to create a cursor, namely the click hotspot. You can't tell it exactly which pixel in the picture is used to determine where the user clicked.

This is one of the ways we can instantiate a System.Windows.Forms.Cursor object by passing it a Stream object. 3) I also have a ".ico" file in the solution explorer with me. Now, putting the ".ico" file in a Stream and passing it to "System.Windows.Forms.Cursor" constructor gives an argument exception. My queries are: 1) Does .Net support the process of providing ".ico" file to the "System.Windows.Forms.Cursor" constructor in a Stream? 2) Does .net provide a way to take the ".ico" file in a MemoryStream and convert it to some format acceptable by System.Windows.Forms.Cursor" constructor? Re: .ico to .cur conversion in stream object Luc Pattyn31-Jul-07 1:20 Luc Pattyn 31-Jul-07 1:20  Hi, it will not work. read up MSDN on the Cursor Constructor (Stream) and you will see the remark: The data stream specified by stream must contain a cursor (.cur) file. So you can't just give it any stream you would like (ICO file, some image, whatever). Conclusion: you must interactively create your cursor, I guess either using Visual Studio or some other tool.

If I take the ".ico" file in a MemoryStream. Then can I convert this MemoryStream to contain the cursor result? I am sorry to bother you on this again and again . But your reply will really be useful. Then finally I can decide which way to select.
