I have an app in which I want to expose a COM object, so another app can get some info from it. I tried just creating my COM object in the app, but that wasn't working, so I tried to create an ZctiveX Library and put the COM Object in there. All I really want to do is have this object hold some string data. Seems simple. So I go to the type Library editor, and add a property. Two appear, a put and a get. Seems logical. Now what combination of Attribute | Return Type and Parameters | Return Type and Parameters | Modifier | Type do I need to make this work? Setting everything to WideString just gives me "Inconsistent Property Functions"? I'm completely lost, and of course, am on the road, so I don't have my Delphi COM book with me. Please help!!!

Now what combination of Attribute | Return Type and Parameters | Return Type and Parameters | Modifier | Type do I need to make this work? Setting everything to WideString just gives me "Inconsistent Property Functions"? Are you using the editor in IDL mode or Pascal mode? IDL Mode: All methods should return HRESULT. Getter should have one parameter, type BSTR, modifier [in]. Setter should have one parameter, type BSTR*, modifier [out, retval]. Pascal Mode: With the caution that I never use this mode, it looks like Getter should have no paramters (but the type on the attributes tab must be set to widestring), and the setter should have one parameter, type widestring, no modifiers. Normally, once you add the property, on the Attributes tab you set the type, and this does everything for you automatically.

I got it to accept what I wanted finally, though I didn't quite do this. Still, the damn thing doesn't work. How does one control whether you are creating an in process or out of proccess server?

The easiest way to do that for me was to add automation object to application that serves data. The only problem is that if client wants to "establish connection" i.e. to create COM object is that Windows will start automatically your application which implements COM object. If you don't want to do that is to read on http://www.blong.com/Conferences/IConUK2000/DelphiMoreAutomation/More%20Automation%20In%20Delphi.htm Additional Feature that Automation Object gives you is that you can tell your "server" application to do something ... like MS Word can i.e. create new document, close, etc. /Marin "Brad M" <Windopaene (AT) noYAHspamformeOO (DOT) COM> wrote Quote: So I'm trying to do some easy stuff, but I'm clearing doing something wrong, and it has been years since I did this stuff.
