Is there an alternative to Application.DelayInitialize for Delphi 7? I'm trying to create a Delphi 7 Service that hosts a COM Server but it doesn't work and I believe it is because I'm not using Application.DelayInitialize.
Alternative to Application.DelayInitialize for Delphi 7 Service?

I have written several COM-hosting services using BCB6, and they all work fine in all Windows versions from Win9x onwards, so I have had to deal with this same issue many times.
Simply don't call
Application.Initialize()at process startup on Win2003+, wait until theTService'sOnStartorOnExecuteevent to call it. That way, the service API is running before any COM objects are initialized.The trick is to delay the call to
Application.Initialize()ONLY on Win2003+ and ONLY when the service is actually running. DO NOT delay the call if either:Under those conditions, call
Application.Initialize()normally at process startup.So, you will need to check the OS version and the command line parameters to know when to call
Application.Initialize()correctly.
