load a dtm at run time

edited February 2002 in General
Hi

I use the Query Designer of RepportBuilder to load and store '.dtm' files.
Is it possible to load a dtm file at run time just before printing a report
(with the TppReport) ?

Thank you

    You can free the previous datamodule, and load a new one via the
    datamodule's template object.

    procedure...
    var
    lDataModule: TdaDataModule;
    begin

    lDataModule := daGetDataModule(ppReport1);
    lDataModule.Free;

    lDataModule := TdaDatamodule.Create(Self);
    lDataModule.Template.FileName := 'C:\DataModules\Customer.dtm';
    lDataModule.Template.LoadFromFile;
    lDataModule.Report := ppReport1;
    ...

    Hello

    I use the TdaQueryDesigner sample in order to save the SQL result in my
    DataBase, this is to make the user construct his own queries.


    -----------------------------------
    if FMemoryStream.Size > 0 then LoadSQLFromStream(FSQL, FMemoryStream);

    lDialog := TdaQueryDesignerForm.Create(Application);
    lDialog.OnValidateName := DataViewValidateNameEvent;
    lDialog.SQLClass := TdaSQL;
    lDialog.SQL.Assign(FSQL);

    lDialog.Initialize;

    If NombreConsulta.Text <> EmptyStr then lDialog.Caption :=
    NombreConsulta.Text;


    if (lDialog.ShowModal = mrOK) then
    begin
    FSQL.Assign(lDialog.SQL);
    SaveSQLToStream(FSQL, FMemoryStream);
    ......
    ....
    ...
    end;

    lDialog.Free;
    ---------------------------------

    How can I reuse the SQL result saved in some table of my DB as a DTM file so
    my users can use the queries designed previously in his own report builder
    templates????


    Thanks

    Hello,

    For future reference, please use your real name when posting to these
    newsgroups.

    The .dtm file is a complete template representation of the entire DADE
    data module (or entire data workspace in ReportBuilder) not just single
    queries like you are creating. RB currently does not have the built-in
    capability to save and load individual dataviews (queries).

    Thanks Nico

    I know RB doesn't have the built-in capability, that's why I'm asking you
    how to make this possible?

    Supose I create on runtime an empty datamodule, if I can create just one
    view into it and load the SQL constructed before this can make the trick.


    Thanks so much.

    Here is an rbWiki example that shows how to create DataViews via code.
