A few questions with regards to RichEdit
Posted: Wed Jun 10, 2009 8:03 amHi guys,
These questions uses a reduced, self-contained example that'll appear way below as point of reference. Just copy it to \fwh\samples and compile and run it from there.
So here's the question:
1. When I click on File -> Edit, the dialogue box appear but the second RTF control (oEdit) doesn't appear. Why and how to solve this?
2. If user run this program and selects File -> Exit, the program terminates normally. However, if user runs File -> Edit prior to that, this error message appears:
Same question, why and how to solve it?
TIA
p.s. I think this post is basically asking the same issue.
