Bad RTF table causing RichView to error

[jgkoehn]

Greetings Sergey,

I am getting an error in this code:

First chance exception at $75D50144. Exception class EListError with message 'List index out of bounds (-1). TRVList is empty'.

I know it is bad RTF code on a Table (however, I can't always fix the bad RTF tables. These can be from users. Is there a way to handle this more robustly?)

Current code in RV22.2

Code: Select all

function TRVRTFReader.DoTable(WhatHappens: TRVRTFTableEventKind): Boolean;
begin
  Result := True;
  UpdateMarker;
  if Assigned(FOnTable) then
    FOnTable(Self, WhatHappens, Result);
  AfterTableRow := WhatHappens in [rvf_tbl_RowEnd, rvf_tbl_TableEnd,
    rvf_tbl_TableForcedEnd];
end;

Ideas?

This exception happens in try..except block, and finally LoadRTF function simply returns False.
The exception is not noticeable unless debugging in Delhi IDE.

Is this related Sergey?
It is showing up in the Richview interface but not always.

It is highly possible I've done something wrong and just have no idea on how to get to the bottom of it.

If the error text is shown on TRichView itself, this mean that an exception happens while drawing content.
Most probably. it happens because TRichView is not formatted.
Do not forget to call Format after loading.
