Resetting Report for new values.

rbuser

Sorry I think I went brain dead.
I have Delphi 5, Reportbuilder 6.x
The report runs fine the first time, but when I change values in the data
set and rerun the report
it still has the previous data. I tried doing report.reset but to no
avail.
I know it is something simple, but I guess I can't see the tree for the
forest.
Thanks for any help.

Hi Walt,

try 'Report.Engine.Reset'.

Tried this ... same result.
It seems that if I close the form and then go back I can get report to print
with new values the first time.. but then
it retains those values until I close the form.

Walt,

I don't know how you are changing the data, can you refresh your dataset
components before calling 'Reset'?

Ok ... here is what I am doing.
I have a form ... I added a report. (no pipeline)
Listbox.
Button (called Print)
Double click on report .... setup query for table, ect and sort .
I run the program ...
I select the data in the list box that I want created.
when I click on print ... the table is emptied of previous data ... and new
data is inserted.
The report should then display the data. (it does the first time)
If I then select (from the list box) other data .... the table is emptied
and the new data is inserted.
But the report still shows. the old data.

Note :
if I add a dbpipeline to the form and associate to the report then the data
does change on new selection but the sorting is all wrong.

I must be missing something ... I,m sure this is extremely simple.

Buy the way RB is the greatest invention since the wheel.

You actually need to go through the dataviews and reset them to force them
to reretrieve data. Here is a method which will accomplish this for you. You
still should call Report.Reset, especially if you are caching pages.

procedure RefreshDataForReport(aReport: TppReport);
begin

lModule := daGetDataModule(aReport);

for liIndex := 0 to lModule.DataViewCount - 1 do
lModule.DataViews[liIndex].OutOfSync;

end;

Ok .... now I really feel stupid.
What type is lModule.
I have searched for daGetDataModule with no results.
Do I need to add something to my uses clause.
