Register for an application

[Guest]

I'm looking for infomation about registering an application in Windows. I have a client program and a server program. If the user opens the client first and there is no server to connect to I want it to register my app and when the server opens be notified. I know this is possible in OS10 but I'm not sure about windows. Any help?

I looked at the documentation on this and I don't see how it helps me. I don't want to load a dll, I just want to be notified when my second app starts running. I also don't want to have to poll for it.

I'm not sure I understand. If you are asking if the o/s provides a way for
the first instance of an application to be automatically notified of the
launch of a subsequent instance then the answer is no. You'd have to build
that.

However, if your application is composed of an executable and a DLL then the
DLL will receive DLL_PROCESS_ATTACH notifications every time that an
instance (initial or subsequent) is launched. Note however that those
notifications come in the context of the application, however.
