Writing COM Automation Events

When creating Automation Object if I don't check the option "Generate Event support code" then can I add Events later. I am using Builder 6.0.Also if this cannot be done then what does the option "new dispinterface" in Type Library do ?

Writing COM Automation Events, Parameters passing problem.

Hello,I wrote OLE Automation Server and Client including event fireing.the event fireing works fine as long as I using 1 or less parameters in the OnEvent. when I use 2 or more parameters the Evets fails in the client. when I looked for the problem in the client i found that the server sends the parameters in Left-To-Right order and the Client expects Right-To-Left order. I saw that in the TBL.pas file in the "Invoke" function. I have checked in C++ COM and I understand that the standart is Right-To-Left order.SO, why the server Flips parameters order? can it be a BUG?

Writing COM Automation Events

This example works fine when client and server are in the same machine. In differents machines the server starts and the client can use the methods implemented in the server but the events part don't work. As I can see in the implementation of TEventSink.QueryInterface the param IID never is equal to ISimpleEventServerEvents. Someone knows what to do?jmcanals@amper.es Jim Reynolds http://threads.codegear.com/threads/threads.exe/userall?commentid=28642 http://threads.codegear.com/threads/threads.exe/view?commentid=28642 2001-04-16T11:10:44-07:00 2001-04-16T11:10:44-07:00

Writing COM Automation Events

I have written a server that returns events. It functions fine when the client and server are on the same machine. If put the server and client of different machines, the call to the server works fine, but the events to not get returned to the client. I am using a Windows 2000 machine as the server and an NT 4.0 machine as the client. Do you have any ideas what needs to be fixed to make this work correctly?
