Replacing TppReportTemplate

rbuser

Is it possible to replace the TppReportTemplate ?

I would like to build my own load and save function for the report Template.
The Designer.OnCustomOpenDoc did't match for me.

regards

Hi Andreas,

How are the Load and Save functions insufficient for your needs? The
TppReportTemplate class in embedded and cannot be replaced. Please let me
know what your ultimate goal is and I'll try to find a work-around for you
as quickly as possible.

I would like to load and save the report template to and from a
MemoryStream.
For the main report it works fine with the OnCustomOpenDoc,
But i use a subreport in my main form which i load dynamically an the
ReportBeforePrint event

SubReport1.Report.Template.DataBaseSettings.Name := 'SchriftKopf';

SubReport1.Report.Template.LoadFromDataBase;

How can i do this to load from a MemoryStream ? (Without replaceing the
template ?)

The next point, how can i enable the "Save" and "Open" and "Save To"
menuitems in the Report Designer when i don't use a DataPipelin in the
Template.Databasesettings ? (When i remove the DataPipeline, the menu items
allways gets disabled .... )

thanxs in advance

Hi Andreas,

It is possible to load and save a template from a MemoryStream using the
TppTemplate.LoadFromStream routine. I am not fully clear about what is
happening to prevent you from loading a template from stream and then
dynamically adding a template from database to a subreport in your main
report. You could possibly load the template from database and save it to
stream first, then load it as you need it throughout the process of your
application.

Be sure you have the TppDesigner.AllowSaveToFile property set to True to
enable all the file menu items. Also be sure that your
Report.Template.SaveTo property is set to stFile rather than stDatabase.
