Try this:
Delphi-Quellcode:
var wdString: WideString;
wdString := 'blabla';
WordApplication1.Selection.Text := wdString;
WordApplication1.Selection.MoveRight(wdCell);
or
WordApplication1.Selection.TypeText(wdString);
or just
WordApplication1.Selection.TypeText('Text');
but remember, Word expects
Unicode strings (WideString)
