Problem w/string variables

rbuser

Hi,

I am using RB 7.04.
I have a report with one group and multiple (3) detail lines. Variable1 is
in the detail section and Variable2 is in the group header section.
Variable1 is simply calculating something based on the details and it is
invisible. Then I want to set Variable2 to the value of Variable1 so it
will display in the group header section. Right now, Variable2 comes out
blank, but according to my code for Variabe1, it is supposed to show
something.

Any suggestions?

Thanks,
Yelena

Hi Yelena,

Be sure you have the correct datatype selected for Variable2. The event
code in the OnCalc event of Variable1 should look something like the
following (in RAP).

procedure Variable1OnCalc(var Value: Variant);
begin
Value := Value + Report.DataPipeline['AmountPaid'];
Variable2.Value := Variable2.Value + Report.DataPipeline['AmountPaid'];

end;

This is the code I have on the OnCalc event of the variable located in the
detail section:

{Referece Range header text changes according to format code.}
if (PipeSub3['format_code'] <> 1) then
begin
if ((PipeSub3['format_code'] = 2) OR (PipeSub3['format_code'] = 3)) then
begin
if (Variable63.AsString = '') or (Variable63.AsString = 'Cutoff') then
Variable63.AsString := 'Cutoff'
else
Variable63.AsString := 'Reference Range/Cutoff';
end
else {we know it is 0}
begin
if (Variable63.AsString = '') or (Variable63.AsString = 'Reference
Range') then
Variable63.AsString := 'Reference Range'
else
Variable63.AsString := 'Reference Range/Cutoff';
end;
end else
Variable63.AsString := '';
end;

Variable63 is in my first of three groups. Both varaible datatypes are
string. The report is a 2-pass report and the format_code.value = 0. The
text on the group is always blank. Variable63 is visible. Also, I did not
change the timing on the variable in the detail section.

Hi Yelena,

I would suggest placing ShowMessage() calls in each of these cases to find
out exactly what is happening in this method. This is a quick easy way to
debug RAP code on the fly. As far as the code goes, at first glance it
looks ok.

I already did that, and everything looks correct with the code, but nothing
is displaying. I thought it may be because it's in a subreport, not the
main report.

Any other ideas?

Thanks,

Hi Yelena,

If the correct code you posted is being fired at the proper time, then there
has to be some place where the variable is either being reset, or simply
that the variable is not being set at all. If you are updating a variable
in the main report from a subreport, check to see that the global var you
created is infact the correct value and that it is properly linked to the
TppVariable in your main report. Also, check the timing of the variable to
be sure it is not reseting at the wrong time.
