The new TfrxReport.EnabledDatasets property

toverell

Currently available FR 3.0 build and CBuilder 5.

I have not been able to find the new TfrxReport.EnabledDatasets property in the current distribution of FR 3.

The changes.txt indicates that this is version 3.01 however designer still says FR 3.0.

I am assuming that this property is to address the problems of referencing valid datasets in non data linked bands like Page Header and Report Title etc.

The inability to do this is a real show stopper for me.

This property limites the number of datasets available to a report.
To solve non-databands problem, fix the
frxDBSet.pas:

function TfrxDBDataset.GetDisplayText(Index: String): String;
var
  i: Integer;
begin
  if not FInitialized then
    Initialize1;
  if DataSetActive then
    if Fields.Count = 0 then
      Result := FDS.FieldByName(Index).DisplayText
    else
    begin
      i := Fields.IndexOf(Index);
      if i <> -1 then
        Result := TField(Fields.Objects[i]).DisplayText
      else
      begin
        Result := frxResources.Get('dbFldNotFound') + ' ' + UserName + '."'
+
          Index + '"';
        ReportRef.Errors.Add(ReportRef.CurObject + ': ' + Result);
      end;
    end
  else
    Result := UserName + '."' + Index + '"';
end;

function TfrxDBDataset.GetValue(Index: String): Variant;
var
  i: Integer;
begin
  if not FInitialized then
    Initialize1;
  i := Fields.IndexOf(Index);
  if i <> -1 then
    Result := TField(Fields.Objects[i]).Value
  else
  begin
    Result := Null;
    ReportRef.Errors.Add(ReportRef.CurObject + ': ' +
      frxResources.Get('dbFldNotFound') + ' ' + UserName + '."' + Index +
'"');
  end;
end;
