ppvariable & blankwhenzero

rbuser

Hi,

Using ppvariable with displayformat of 0% and a field data type of double.
When zero value field displays as 0%
I want to suppress this and display spaces when zero.There is no
blankwhenzero property on this component. I've tried using onformat event as
follows
'if value = 0 then text := ' ';
This works for the zeror case but I lose my formatting
when value is non zero, ie I get a figure containing umpteen deciamla places
and not % formatting. I've tried resetting the displayformat ifvalue not =
zero but no go.

Am I on the right track or is there a much simpler solution.

Cheers

Tony,

what about setting the Visible Property of the ppVariable, does this work?

Stefan,

That is another approach I hadn't considered and will probably give me a
viable workaround. However, I think I would have to use another event, as
the problem with onformat is that it seems to assume as soon as you provide
a procedure for it to go to that all the formatting is undone and it assumes
you will do all your own formatting.

Tony,

don't use any OnFormat event handler at all. Use OnPrint with this code:

if ppVariable1.Value < 0.001 then
ppVariable1.Visible := False
else
ppVariable1.Visible := True;

It's never a good idea to check a double against an exact value (0 in this
case), so I use < 0.001 in this example. You have to adjust the value to
your needs.
