Thnaks for that.
Part 2 seems to work (I'd actually tried to do that, but forgot to give the focus to the ScintillaVB container 1st - then to scintilla control that it creates)
1st 1 seems a bit more of a problem. VB6 has a 'KeyPreview' property on the container. This means that I get to see key events in the container before they go to the component in the container that has focus. But it appears, as you say, that the unshifted cursor keys are not forwarded to the container in the 1st place. Don't appear to have the facilitity to override either - unless someone can tell me different.
Cheers

Hey Simon
Issue 1: This is occurring because your container is swallowing the
key events. You need to find out which method to override and return
false. For example, embedding Scintilla in a Control in C#, you need
to override the following method:
protected override bool ProcessDialogKey(Keys keyData) {
return false;
}
The control then forwards the necessary key events to scintilla
itself. With VB I assume you will add the event handler, and then set
one of the event properties to False.
Issue 2:
How are you settting the caret position and getting focus? In C#, I'd
set the caret position and use the GRABFOCUS call, like so:
scintilla.CurrentPos = 3;
scintilla.SelectionStart = scintilla.CurrentPos;
scintilla.SelectionEnd = scintilla.CurrentPos;
scintilla.GrabFocus();
These will of course need to be adapted to ScintillaVB, but the
concepts should be the same.
If you are moving the caret position to somewhere outside of the
visible area, you will also need to call the ScrollCaret() method to
ensure the current position is scrolled into view.
Hope that helps,
Matt
