Communicating between two services

Hi,

If I want to communicate between two Services with the WM_CopyData messaging system then how to get the Handle of the Service ?
I would prefer not to use Socket / Named pipes.

I use Delphi on Windows.

Regards
Allan

You can use custom message too - look in this article:
http://www.delphi-central.com/ipc_sendmessage.aspx

Custom message can be adopted to use WM_CopyData or just look how to find client app (using FindWindow)
This is not a fancy way - but works.

Second way is to broadcust a custom created message (RegisterWindowMessage) (send to not specific window) - but this is also not so usual way

Since it is a Service I will not get a result for FindWindow, that will not allow me to use the first option.

Broadcast will not be refined method either.

Please note that both the services are mine and I have the liberty to store details in a text file (eg: Handle etc) for the other service to read.
