How to work with dynamic created Report / DataSets ?
Hi all...
I create the Report, the Designer, the Dataset??s during runtime. Then i loading a Report from a File and open the Report with the Designer. The Designer is showing but i can??t assign my dynamicly created frxDBDatasets to the Report because they are not showing in the Data Menu.
When i use Report.Datasets.Add(myfrxDBDataset) then i get an Access Violation from the Report.
Example:

Example:
var
  FReport: TfrxReport;
  FDesigner: TfrxDesigner;
  Query: TIBCQuery;
  FDataSet: TfrxDBDataset;
FReport:= TfrxReport.Create(nil);
FDesigner:= TfrxDesigner.Create(FReport);
Query:= TIBCQuery.Create(FReport);
FDataSet:= TfrxDBDataset.Create(FReport);
FDataSet.Name:= 'DataSet1';
FDataSet.DataSet:= Query;
.
// Data loading into Query
.
FReport.LoadFromFile(FReportFileLocation + NormalForm,False); // without the Loading i get a clear Report without a Page but with the Dataset when i run the "DataSets.Add" Line
FReport.DataSets.Add(DataSetPositions); // with this i get AccessViolation, without i can??t see the DataSet
.
.
FReport.Free;
