Hi,

has anyone had problems dynamically creating frame objects within an in-process
COM server (i.e. a DLL).

I have some code inside a COM server which creates a form and displays it.
Later, it dynamically creates some frames and places these on the form.

This works fine in the executable, but when attempting to do the same in a DLL,
I get the following exception :-

Exception EInvalidOperation with message 'Control 'TestFrame' has no parent
window'
This only happens when certain controls exist on the frame, for example the
error occurs, if I place a TMemo component on the frame.

Does anyone know why this is happening ?

Thanks in advance.
Phil.

Sorry, never used TFrame, much less in a COM server.

Turns out it was related to the global TApplication object in the DLL not having
a handle to the host applications main window.  I've temporarily fixed it so
that the client passes in the handle on startup to the server but it's a yucky
hack.

Alex, do you know if there's a better way of getting the host applications main
window handle ?

Phil.

Phil, I'm pretty sure this was discussed a while ago. I suggest the vcl
