How to communicate a Web Application to Window Application

Question

Hi! I am developing a Web Application that will somewhat talk to a Window Application. As of now, the alternate solution I made was:
1. The web application will create a file "c:\myFile.txt"
2. The window app will always check if there is such existing file.
3. If the window app found the "myFile.txt", it will read the content and delete it.

but for me, thats not good... I would want it to be in way like using Winsock. the web app will communicate with the window app without creating a file. But HOW? What method will i use?
I am not very familiar with SOAP, but can SOAP do that? HOW?

I will really appreaciate if you can give me a sample code.

Thanks in advance!
