Problem with crash after modifying fonts in a table

[DickBryant]

I'm using this code to force all fonts in a given table column to a standard style (they may have been pasted from other sources, etc.):

//Get the 'handle' of the inserted table
for i := Fmain.RichViewEdit1.ItemCount - 1 downto 0 do
begin
case Fmain.RichViewEdit1.GetItemStyle(i) of
rvsTable:
Table := TRVTableItemInfo(Fmain.RichViewEdit1.GetItem(i));
end;
end;
ItemNo := Fmain.RichViewEdit1.GetItemNo(table);

Fmain.RichViewEdit1.BeginItemModify(ItemNo, TableData);


for i := 0 to MasterRVTable.RowCount - 1 do
begin
for j := 0 to MasterRVTable.Cells[i,1].ItemCount - 1 do
begin
if MasterRVTable.Cells[i,1].GetItemStyle(j) <> 1 then
MasterRVTable.Cells[i,1].GetItem(j).StyleNo := 1;
end;
end;


FMain.RichViewEdit1.EndItemModify(ItemNo, TableData);
FMain.RichViewEdit1.Change;
FMain.RichViewEdit1.Format;

For small, easy files this works. But for a large and complex file (900 rows) it crashes during the Format operation in CRVFData here. If I run a similar operation on columns in the same table that do not require any changes then the format operation completes OK - so it must be being caused by the changes made to the fonts.

try
{$IFNDEF RVDONOTUSEUNICODE}
if GetRVStyle.TextStyles[GetActualStyle(item)].Unicode then
GetStringTypeExW(Locale, CT_CTYPE2, Pointer(s), Len, CharTypes^)
else
{$ENDIF}
----> GetStringTypeExA(Locale, CT_CTYPE2, Pointer(s), Len, CharTypes^);
case CharTypes[0] of
C2_LEFTTORIGHT:
Start := rvbdLeftToRight;
C2_RIGHTTOLEFT:
Start := rvbdRightToLeft;

[Sergey Tkachenko]

The error may occur when you assign 1 to:
- StyleNo of non-text item (they must not be changed)
- StyleNo of text item having different value of FMain.RichViewEdit1.Style.TextStyles[StyleNo].Unicode

Do you want to make this operation undoable by users (with Ctrl+Z)

[DickBryant]

It's not necessary to make the change undo-able.

Could you give a short code example on how to avoid these:

>> The error may occur when you assign 1 to:
- StyleNo of non-text item (they must not be changed)
- StyleNo of text item having different value of FMain.RichViewEdit1.Style.TextStyles[StyleNo].Unicode <<

If you could do it in the context of:

for i := 0 to MasterRVTable.RowCount - 1 do
begin
for j := 0 to MasterRVTable.Cells[i,1].ItemCount - 1 do
begin
if MasterRVTable.Cells[i,1].GetItemStyle(j) <> 1 then
MasterRVTable.Cells[i,1].GetItem(j).StyleNo := 1;
end;
end;

That would be great!

[DickBryant]

I've figured out how to AVOID changing the style if it will cause a problem by:

//Check Unicode status of Question Default Font
IsUnicode := FMain.RVStyleQ.TextStyles[1].Unicode;
for i := 0 to MasterRVTable.RowCount - 1 do
begin
for j := 0 to MasterRVTable.Cells[i,1].ItemCount - 1 do
begin
CurrentItemStyle := MasterRVTable.Cells[i,1].GetItemStyle(j);
if ((CurrentItemStyle > -1) and (CurrentItemStyle <> 1)) then
begin
if FMain.RVStyleQ.TextStyles[CurrentItemStyle].Unicode = IsUnicode then
MasterRVTable.Cells[i,1].GetItem(j).StyleNo := 1;
end;
end;
end;

But this leaves text where the desired style (1) is does not match the "unicodeness" of the current item style unchanged. Is there a way to 'convert' the current text item to an item having Style 1?
