Re: [Gambas-user] IsObject(NULL)
hi, PRINT IsObject(NULL) returns TRUE The NULL constant is an object? NULL is almost everything. So IsObject(Null) and IsString(Null) returns TRUE. But IsDate(Null) returns FALSE, whereas Null can be a date. So things are not very logical there. -- Benoît Minisini -- Increase Visibility of Your 3D Game App Earn a Chance To Win $500!

Re: [Gambas-user] IsObject(NULL)
i will describe my thoughts about that, i read the http://gambasdoc.org/help/cat/constants and i saw that a TRUE or FALSE value is a Language constant. Also NULL is a Language constant! So i expected from IsObject() to return FALSE when it is feed with constants as argument. So PRINT IsObject(TRUE) 'False PRINT IsObject(FALSE) 'False PRINT IsObject(0) 'False PRINT IsObject(a string) 'False But PRINT IsObject(NULL) 'True Some more thoughts.. In wiki says that NULL is a void string and indeed... PRINT IsObject() 'True 1) But what if someone want to check a void string? 2) How a PRINT IsObject(a string) 'is False and a PRINT IsObject() 'is not False both are strings and not Objects.

But IsObject(NULL) i think is different from IsObject(oMyNullObject) The first is the constant the second is a NULL object. Also see IsObject() which here is a empty string. If i am wrong please correct me. -- Regards, Demosthenes -- Increase Visibility of Your 3D Game App Earn a Chance To Win $500!

IsObject(NULL) doesn't refer to the NULL constant being an object, it is answering correctly that a vRef=NULL is a null reference! ok, may be Bruce is right here, NULL can be a reference to a NULL object but also a Variant or a Dynamic array or anything with a NULL reference. So IsObject() cannot determine the reference to object but to a NULL reference. i was just thinking if there is a way the IsObject() can be more accurate if something is NULL object or anything else. I was thinking if it was a NULL object, ok it is an object If it was anything else NULL, is not an object for example DIM aStrings AS String[] 'is a null object PRINT IsObject(aStrings) 'True DIM v AS Variant = NULL PRINT IsObject(v) 'here i expected false i tried to determine this difference with TypeOf DIM aStrings AS String[] 'is a null object PRINT TypeOf(aStrings) 'but i get 15 NULL value DIM v AS Variant = NULL PRINT TypeOf(v) 'again 15 NULL value instead 11 so i think there is no way to make difference of objects or anything else if they are NULL. -- Regards, Demosthenes -- Increase Visibility of Your 3D Game App Earn a Chance To Win $500!
