Repalcing the autosearch dialog

rbuser

Hi,

How can I replace the autoserach dialog with my own?
I developed a standard dialog that is able to define search criteria field
as checkbox, radiogroup, lookup, etc. and based on what the user put on the
dialog, it produces the "WHERE" condition for the SQL.

I would like:
1. have the possibibility to show my own dialog.
2. access to the SQL it is being processed and add to it the generate
"WHERE" condition the "WHERE" condition prepared by the dialog box

Could someone point me in the right direction?

Thanks

There is a custom autosearch dialog example in the demo directory in the
Autosearch folder.

If you want to create a form without descending from TppAutosearchDialog,
then you'll have to descend from TppCustomAutosearchDialog. See the
interface section in ppForms.pas to see what you have to implement.

What version of RB are you using? This tip was built for RB 6 which does
this, though it needs a modified version of TppCustomAutosearchDialog in
ppForms.pas:

You should still create autosearch fields on the report, and use those field
values to update the where clause, as shown in the autosearch demos that
update the Where clause of a TQuery. This piece of the architecture should
work the same way, wether you use our dialog, or a custom dialog.

I've not been able to get this program to work. The FVendor and FParts
are cleared before they can be used and there is always an access
violation. Are there any more examples of building a custom search dialog?

Ok, if the 'tip' isn't stable, it has a decent amount of code in it that was
written some time ago for D6. The demo's approach is the one to take when
wanting to descend from TppCustomAutosearchDialog. Otherwise, you should
descend from TppAutosearchDialog and examine our autosearch demos included
in the RBuilder installation which do this.
