Some questions about QReport

Hi

  I have some problems in QReport.

1.I 've designed a Qreport on a form and i want to call "QReprt.Preview " method
 from another form ,When i do that, Preview is shown but it doesn't give me ant lists.

2-How can i use a function or variable in QReport(not QReport's built in functions or variables)?

Thank you

If you use QReport with SQLs you have to Open these SQLs before showing, best it is done in the QReport OnBeforePrint Event. (Was that your problem for 1.?)
for 2. : What do you mean with 'use functions in QReport'? If you mean doing some calculations when printing your data you can use the QReport events. For example you can add some fields to your query and set them to be calculated fields, in the event OnCalculateFields from the query you can do the things you want with the data of this dataset, this event is fired for all datasets you get. Or in the events of QReport bands you can do things with the data in the bands ... depends on what you want to do ... or just write your own class that inhertits from QReport and add your functions ...
