Hello,
For those interested in getting the FreeReports 2.32 components to
work with IBO4, here's how I got it cranked up. (hopefully not too
off-topic).

I have emailed the fixes to the Free/Fast Report maintainers, however they're
certainly not the quickest to answer their mail :(

I have only tested this briefly with Delphi 5 Pro with a simple
report. My main interest was to be able to play with the reporting
components with native IBO controls and my own data.

cheers
Mark

---- start fixes ---

1 - In fr.inc replace the line:

{$DEFINE IBO}

with:

{$DEFINE IBO}
// Also uncomment the following line if you have IB_Objects ver4.0+.
{$DEFINE IBO4}

2 - In FreeRep5.dpk replace the line:

IBO_D5,

with:

{$IFDEF IBO4}
IBO40CRT_D5,
IBO40FRT_D5,
IBO40TRT_D5,
IBO40VRT_D5,
IBO40XRT_D5,
{$ELSE}
IBO_D5,
{$ENDIF}

3 - In fr_class.pas the code to see if the dataset that a field
is contained in is Active, is not compatible with IBO4's
TIB_Column properties.

3a - On line 5411 replace:

if not F.DataSet.Active then

with:

if not DSet.Active then

3b - On line 5412 replace:

F.DataSet.Open;

with:

DSet.Open;

3c - On line 5430 replace:

if not F.DataSet.Active then

with:

if not D.Active then

3d - On line 5431 replace:

F.DataSet.Open;

with:

D.Open;
