Dynamic Data Exchange with Windows Service

[sutch]

I have created a DDE( Dynamic-Data Exchange) Client (Console) application to interact with a legacy DDE Server. This client is working perfectly

I am asked to develop same functionality in a windows service. I have already tried the following and have not achieved success til yet
1) Loading the Assembly (DLL) containing the DDE Client using AppDomain.Load / Assembly.Load
2) Loading a DDE Client (console app) using System.Diagnostics.Process.Start(filename);
3) Implementing DDE Client functionality in Windows Service itself.

It seems that Windows Service do not allow calling Windows Form Controls. So that is a problem.

My objective is to establish a DDE connection using DdeConnect and then send request to the DDE Server.

Can Somebody help me resolving this issue

thanx in advanced

Windows services exists and run in their own terminal session.. which is transparent to the active users... meaning if you try opening a notepad from a windows service

System.Diagnostics.Process.Start("notepad.exe", @"C:\S.txt");
 

it wont be visible... to the user.. though it will be "listed" in task manager..
If your program has a GUI windows service wont help( windows service run in background)... Windows service do not require active users...
