Hi,

My system runs on Win98, Celeron processor. I have the following questions:

1. At times, when opening rvf files in a sequence, Delphi gives an error

Canvas does not allow drawing. What can be the possible causes of this error.

It does not always happen,but only once in a while. Could the error be attributed

to RvE.Format, since I did call format at certain lines of the codes.

2. Do I need to REFRESH (not in helpfile) after FORMAT/CLEAR.

Do I need to FORMAT after clearing(CLEAR)?

What does REFRESH do?

3. If I insert text with AddNL, and a certain textstyle does not exists,

I will get Listindex out of bound. Rve.FORMAT is issued after this. Will

this error be reflected in the FORMAT_ procedure as LastItemFormatted(this

integer value will be negative then)? I am doing a lengthy debugging for

my company's application and need your kind comments.

Thanks you.
