You can use TCP/IP connection. In the C# application , you can use <br />
System.Net.Sockets; to get functions to send TCP/IP data to any specified IP/Port. At Delphi side you can use TServerSocket component avaibale in the older versions or latest indy components to receive data from C# app.<br />

Hi<br />
<br />
I have two applications.<br />
<br />
One is written in Delphi.<br />
<br />
The other in MS C#.<br />
<br />
I need to communicate between the two.<br />
<br />
I use text files and filewatcher now, but that seems kind of crude and the information is visible to the user.<br />
<br />
I know I can use ShellExecute to open one app from the other app, but that seems to be its extent.<br />
<br />
Is there some other way of sending information back and forth??<br />
