Class does not contain a member - but it does.

[adrianxw]

I have a class in a package which contains a public member, a property in fact. If I view the class in the structure window, I can see the member declared as public.

If I try to use this class in another program, I get the error "Tclassname" does not contain a member named "name".

Why would it not see the member when it would appear to be visible?

The class contains over 2000 lines of code. The value I want is only mentioned on a few lines though. It sort of reduces to this...

Tclassname = class(TComponent)
private
{ Private declarations }
FTimeStamp: TDateTime;
protected
{ Protected declarations }
public
{ Public declarations }
property TimeStamp: TDateTime read FTimeStamp;
published
{ Published declarations }
end;

... with FTimeStamp being set upon receipt of certain events.

In the calling program, I am trying to set...

Value := Class.TimeStamp;

... nothing real fancy.

If I try to use this class in another program, I get the error "Tclassname" does not contain a member named "name".

what has timestamp to do with the error? do you have a name property or not??

I have a private class member called FTimeStamp, and a public property called TimeStamp which allows it to be read by programs instantiating this class.

When, in a calling program, I say...

x := Class.TimeStamp;

... I see an error saying Class does not contain a member etc., thus TimeStamp has everything to do with it!

so the class you are using is in a runtime package? (the bpl must be distributed with the app)

if this is the case, do you have the same problem when not using runtime packages?

The .bpl file is loaded into the IDE, and I can pull components from the palette into the application. I do not distribute the .bpl.

That said, the problem has "gone away". I don't know what I did to correct this, although I have found that if I have both the client and the component loaded into the IDE at the same time, frequently, changes to one, do not appear in the other straight away - closing the IDE and restarting it seems to fix it. I did try that in this instance and it appeared not to work, but perhaps I goofed somewhere.
