Does the C++ COM Object do painting properly normally ???Not sure what you mean by this, but the COM object is using DirectX internally and just uses the HWND as a mechanism to draw into the panel. Windows is getting time to process messages as other controls on the form are responsive.
have you looked at LockWindowUpdate ?
No. Good point. I will.....
Are you passing the Window Handle for the Form or the Panel ?For the panel.....

Subject: [DUG]: Painting to HWND....

G'Day,
We are developing a Delphi Front End to a C++ COM object. The COM object
needs a HWND to draw some output. As an initial test we are using a TPanel
for this. However the TPanel flickets badly as it tries to repaint itself.
So the question is: What control needs to be used that has a HWND but that
does not flicker withing the Delphi App. As a side issue - The mouse is
also not visible over the TPanel.....
