OnGetAliasForField & OnAssignField event

rbuser

Hi,

Any example for using OnGetAliasForField and OnAssignField event?

Regards,
Danny.

We don't have any specific examples, since this is for the designer window.
There is a data dictionary component which lets you define the field aliases
that the user sees. What are you trying to accomplish?

I am using RB 6.03. And I have tried to install a fresh WIN98 with no
default printer and my application is working fine. Any more clues?

Sorry for mis-posting question in previous posting.

As my application is using XML for passing data from server to client, a ADO
dataset is dynamic created for storing the data. And I am trying to display
the alias field name instead of the database field name. I have try to use
DataDictionary for the matter, but I fail (may be I am trying in a wrong
way). Does there any sample teaching how to dynamic create the Table ppline
and Field ppline without connecting to database?

If you aren't connecting to a database, then you could use the JITPipeline
to retrieve the data. There are examples in the RBuilder installation (main
reports demos) which use the JITPipeline. These demos illustrate how to use
the JIT. You'll have to take it a notch further and define the fields on the
datapipeline at runtime.

To create a field at runtime, see the help file. There are methods such as
Datapipeline.DefineField which creates a field object which you can then
modify.

If you want to see how RB creates a field, see the source in
RBuilder\Source\ppDB.pas
in the TppCustomDataPipeline.CreateDefaultFields method.
