How to pass information from a Windows application to Citrix client?

I have a standalone application (App A) which needs communicates with another application (App B( running on Citrix server using Citrix client environment. I need to collect some information from App A and pass it into the App B. What is best way to do so? Is there any windows API that I can use?

Is both the servers on the same network/subnet, and what ports are your app using.
make sure you can telnet from server A to server B and from server B to server A
maybe the firewall is blocking it and just allow that ports between the servers

Yes, the servers and client machine are on the same network. There is no issue to running the server application thru citrix on the client side.

My questions is how to pass information from an application running on the server to the another application on the client machine? What kind of inter-process communication shall I use? Do I need to use Citrix specific API?

Thanks,

If you like a file-sharing solution, just map an AppA folder "location" to the client's Citrix profile.

Example location available in AppA = "\\machineA\c$\ShareTemp"   (create a ShareTemp folder, though)

On user's Citrix Windows Explorer: "Map a Network Drive" and point to the above location as drive Z:

Make sure NTFS permissions are in place for ShareTemp folder.

It will be more like memory-based solution. AppB will collect some information. I would like pass these information to AppA. If on a standalone machine, I can use Shared Memory mechanism.

Is there a similar approach for communicating the application residing on Citrix server? Is it involving Windows API or Citrix-specific APIs?

Thanks,

MF
