Detecting an automation call

Posted on 2000-05-09

Hi everyone...

I want to do the following: I have a form, which also contains an OLE automation server. So far so good, but how can the application figure out, if it was started by an automation call or directly by a user? I know, I could add a boolean variable or other means to the initilize function of the automation server, but the Form.Create is being called first. I want to forbid the user to call the application directly. Instead the user should get a dialog box. Like I said, the problem is, that the initilize function is being called after the form is being created, so I can't tell if the automation server is going to be created or not. Any ideas?

Regards, Jonny...

Jonny, before diving too much into the problem: what about renaming the application to DLL? This will prevent the user from starting it and it still can be used as automation server (even the icon remains the same :-).

Ciao, Mike

Hi Lischke :-)

Good idea, has one problem though... How do you register this one? Does regsvr32 work? I would still like to know, how I could dectet it... might get handy some time :-)

Mmmh, good point. Try to figure out whether the application exports DLLRegisterServer and 3 other functions (using QuickView from Windows or tdump from Delphi). These functions are used for registering. I doubt this mechanism is different to that of DLLs, but am not sure, though...

Hi all,

You can check how your application was started using something like

if comserver.startmode=smautomation then ...
