I'm using
<DispId(0)> attriubute

for my COM-Interop interfaces...

I have two interfaces one for events and another for properties and methods.

I'm using

<DispId(0)> attriubute to <DispId(16)> attriubute

some are used in one interface and some are used in another. Can I do
ranges like...

<DispId(101)> attriubute

<DispId(201)> attriubute, etc..?

TIA! JerryM

Hi Jerry,

Sorry but I'm not sure I understand your question:

> Can I do ranges like...
> <DispId(101)> attriubute
> <DispId(201)> attriubute, etc..?

Also, the DISPID_VALUE (0) is reserved for default member for the object:
the property or method is invoked when an ActiveX client specifies the
object name without a property or method.

Walter,

Basically I want to know if I can skip DispId values...

Interface1...

<DispId(101)> _
Sub Method1()
<DispId(102)> _
Sub Method2()

Interface2...

<DispId(201)> _
Sub Method3()
<DispId(202)> _
Sub Method4()

etc...

I would like to group certain methods, properties and events into group
using 101, 102, 103, 104 for events, then 201, 202, 203, 204 for properties
and then 301, 302, 303, 304, etc... for Methods. within two different
interfaces. ??? Yes or No?

TIA JerryM

Hi Jerry,

Other than those special DispIDs, you can use arbitrary ID, as long as
they're not duplicate for different property/method.

Walter, Cool! I just wanted to do ranges so I can add new times as I
develop and don't have to renumber everytime I add one new method or
property or event.

Chow! Have a great weekend!

Sorry...

Below the text reads new times and should have read new items...
