Autosearch and RAP using pipelines

rbuser

Hi,

I seem to have found a problem!
If I create a report, use the DADE to create a "pipeline"/dataset, then
using RAP create a autosearchcriteria, everything works well.

If I create a report, using a BDE pipeline, connected to a dataset,table
etc., then using RAP create a autosearchcriteria, it doesn't work ! it just
gives me all the records instead of the filtered ones.

Any idea's/suggestions ?

I'm using Delphi 4, with RB 6.01

Thanks

1. A good place to start is RBuilder\Demos\AutoSearch.

2. Report.AutoSearch parameters are simple parameters that do not really do
anything other than collect information.

3. The Query tools in DADE enable you to define search criteria for a SQL
query that can result in Report.Autosearch parameters being created. The
QueryDataView object manages this. The QueryDataView creates the
Report.AutoSearchParameters and when the values are specified the
QueryDataView updates the TdaSQLObject with the new parameters so that the
proper SQL can be dynamically generated.

4. When not using DADE you need to write the logic to modify the dataset.
See the demos mentioned in 1 above.

Hi,

Ok, thanks, If I understand you correctly, you are saying you can't use
RAP (in the report template) to modify an autosearch on data provided
to the report by a pipeline ?
but you can do it if you create the query/pipeline within the DADE ?
also you can if you modify the autosearch within the app's code ?

Thanks

Cheers
Alan.

No I did not say that you cannot use RAP code.

My question to you is how would implement what you need using Delphi code?
That is the first step. Before you implement anything in RAP code, try
implementing it in Delphi code first. Once you get that working, then
implement it in RAP code.

If you spend some time with the RBuilder\Demos\AutoSearch I think you will
understand what AutoSearch paramters are and how they are used. When not
used with DADE you have to write the code

I may be misunderstanding, but in my opinion your question is not a RAP
question, but a question of how to use AutoSearch parameters.

Play with the RBuilder\Demos\AutoSearch and then post more questions here
and I can help you work thru it....
