Jeff Overcash (TeamB), overcash@onramp.net, explains how to port InfoPower 4 to Delphi 5:
Open ip40_d4.dpk and answer yes to the upgrade question.
View source and change the package ip40_d4 to ip40_d5 on the first line and
change the description to Delphi 5 on line 25.
Open up the options for the package and add to the search path the source
directory. Optionally you can make the Unit output path set to the lib
directory. Also Optional is to remove the DCP directory and allow it to goto
the default Projects\bpl directory.
Next do a file save as ip40_d5.dpk (note these four steps will be done for each
of the packages).
Open the wwlfDef.pas file. At the end add
{$IFDEF VER130}
{$define wwDelphi3Up}
{$define wwDelphi4Up}
{$define wwDelphi5Up}
{$ENDIF}
File wwQuery.pas
line 372 insert before the {$ifdef wwDelphi4Up}
{$ifdef wwDelphi5Up}
if Datatype=ftBCD then
begin
if BCDToCurr(TBcd(Pointer(FFilterFieldBuffer)^), tempValue) then
FFilterParam.AsBCD := tempValue
else FFilterParam.AsBCD := 0;
end
else
{$else}
and add an {$endif} after the wwDelphi4Up stuff (line 390).
Note I think this is correct. I don't use BCD datatypes so this could be incorrect since it is
not tested. If it needs modifying I'll post that later.
File wwQbe.pas
line 586 insert before the {$ifdef wwDelphi4Up}
{$ifdef wwDelphi5Up}
if Datatype=ftBCD then
begin
if BCDToCurr(TBcd(Pointer(FFilterFieldBuffer)^), tempValue) then
FFilterParam.AsBCD := tempValue
else FFilterParam.AsBCD := 0;
end
else
{$else}
and add an {$endif} after the wwDelphi4Up stuff (line 604). (same warning as
before) Note I think this is correct. I don't use BCD datatypes so this could
be incorrect since it is not tested. If it needs modifying I'll post that
later.

line 313 insert before the {$ifdef wwDelphi4Up}

begin
if BCDToCurr(TBcd(Pointer(FFilterFieldBuffer)^), tempValue) then
FFilterParam.AsBCD := tempValue
else FFilterParam.AsBCD := 0;
end
else
{$else}
and add an {$endif} after the wwDelphi4Up stuff (line 331). (same warning as
before) Note I think this is correct. I don't use BCD datatypes so this could
be incorrect since it is not tested. If it needs modifying I'll post that
later.

FFilterParam.AsBCD := tempValue
else FFilterParam.AsBCD := 0;
end
else
{$else}
and add an {$endif} after the wwDelphi4Up stuff (line 1194). (same warning as
before) Note I think this is correct. I don't use BCD datatypes so this could
be incorrect since it is not tested. If it needs modifying I'll post that
later.

Now just compile the package. You will get a couple of out of range warnings,
but they can be ignored.
Next open ip40d_d4.dpk and answer yes to the upgrade question.
View source and change the package ip40d_d4 to ip40d_d5 on the first line and
change the description to Delphi 5 on line 25.
Change the requires to be ip40_d5 on line 30.
Open up the options for the package and add to the search path the source
directory. Optionally you can make the Unit output path set to the lib
directory. Also Optional is to remove the DCP directory and allow it to goto
the default Projects\bpl directory.
Next do a file save as ip40d_d5.dpk

Compile and install the package.
The following is for Enterprise owners.
Next open ip40client.dpk and answer yes to the upgrade question.
View source and change the package ip40client to ip40client_d5 on the first line
and change the description to Delphi 5 on line 25.
Change the requires to be ip40_d5 on line 29.
Open up the options for the package and add to the search path the source
directory. Optionally you can make the Unit output path set to the lib
directory. Also Optional is to remove the DCP directory and allow it to goto
the default Projects\bpl directory.
Next do a file save as ip40client_d5.dpk
