COMSDK with SP4?

[Carlos Rocha]

Hi,

I'm trying COMSDK2816 with SP4 but I cant even make a simple thing like

//---------------------------
LOCAL oComObject AS TS_DelegateDispatchAuto

oComObject := TS_DelegateDispatch{NIL, "MyServer.MyObject"}
//-----------------------------


I get an error stating that '_TS_CoCreateInstance(...)<>S_OK', among a lot more things, like SubCode=>U4'305419896[0x12345678]'

The server exists and is registered (it's a test COM dll made with VB6).

As I don't have Outlook I can't test the provided samples
So, can anyone tell if it's possible to use COMSDK with SP4?

Thanks,
Carlos

Sorry,
oComObject := TS_DelegateDispatch is a typo, in my code it's
oComObject := TS_DelegateDispatchAuto(...

Hi Carlos,

Please see this thread:

We indeed solved it without the COMSDK.

Thanks Jamal

I'm aware of that thread (actually I posted there), but the way I read it is that COMSDK is not needed anymore to automate OpenOffice.

My problem is with COM Automation Events, Variant parameters, and ByteArrays.
In fact I can do everything I need using VB6, but I would like to give COMSDK a shot to not depend on any Visual Studio.

Thanks,
Carlos

Carlos,

I thought that VO COM generated code handles those types.

Personally I never needed COMSDK and I've dealt many with COM objects. The
fact that COMSDK is no longer developed, I would suggest that you do not
waste your time trying to figure it out (unless the developers jump in and
try to help).

Have you tried generating the COM object code in VO and use it?
What sort of results are you getting?

Jamal,

More or less, but with a few limitations. The more importants are:

1. one can't change a variant value passed by ref, what makes impossible e.g. Cancel an operation from an event (it works if the parameter is a boolean).

2. The only way to receive byte arrays is by changing it to a string (there's a function for that, thanks to Robert), but there's no way to pass a byte array to a COM object.

Well, the code is there (except for CPU2800) and if it works I could give it a try. I think I will install 2.7 again and see what happens. My stubbornness is stronger than me :)

Yes, and almost everything works fine. I need to change the generated code sometimes tho, but that's easy when one learn where to touch.
But the fact is that I still depend on VB6 to make everything work (there are even some tricky COM dlls to whom VO generates no code at all).

Carols,

I always admired VB6 even though it's old technology now that it could
handle COM objects very elegantly and VO's way lacked the same ease of use.
Sorry I could not help in this case.
