Hi *,
I need help with OCX component (not visual I guess), which I need use
in Lazarus application (to control another application, which
supplies this OCX control).
I have imported type library using importtl.exe (new unit was created
successfully)
Then in program I have created instance:
v := CreateOleObject('SCAPS.ScSamlightClientCtrl');
or
intf := CreateComObject(CLASS_ScSamlightClientCtrl) as
_DSamlight_client_ctrl_ocx;
What is the type of your V or intf variable?
V: OLEVariant;
intf: _DSamlight_client_ctrl_ocx;
I am wild guessing maybe they are not proper referenced type so the
object is created and then immediately freed.
There is something strange behind scene. I have tried various methods:
I remember in Delphi, I sometimes have to call CoInitialize and
CoUninitialize.
Not sure if FPC has to do the same.
Have you tried that?
Dennis
