It's worked for me in the past to simply override the Form.OnHandleCreated method (it's better to override in derived classes than handle events) for ActiveX controls using something like:

public class MyForm : Form
{
// ...
protected override void OnHandleCreated(EventArgs e)
{
base.OnHandleCreated(e); //
// Put your initialization code here and add it to the Controls property
}
}

The ActiveX control will most likely require a window handle (HWND) in which to be sited (parented). Calling base.OnHandleCreate first makes sure that everything is set up correctly. This handler is called by CreateHandle after creating the handle. It's possible that the DSOFramer requires something different, though. You should check the Microsoft KB[^] or any existing product site for that control for specifics.
