Hello,
I have several newbie questions about COM:
Thank you.
I have several newbie questions about COM:
- What is an interface?
- Is a new GUID generated every time a COM object is recompiled, so as to tell versions apart?
- For backward compatibility, must each new version of a COM object contain at least all the methods and properties from the previous version?
- Can multiple versions of a COM object co-exist on a computer?
- Can I prevent an application from installing an older version of a shared COM object so that my application doesn't break?
- Is there an application that can list an object's methods and properties, or is the object's documentation the only reliable source of info? I tried the OLE/COM Object Viewer and also RegDllView but they don't seem to provide that feature
Thank you.
