I designed two new components, I see it very convenient and useful,
are the TDBSimpleComboBox and TDBSimpleListBox allow you to see the
contents of a table, query, using the DataSource. Are set which fields
you want to see what components and set the key value, all thanks to a
few simple lines of code. Inside the zip file you download there is
also a folder with examples. Tell me what you think and if there is
useful, I need so many of the components so easy to use to interact
with a db.
The only sin is in the component TDBSimpleComboBox run on Ubuntu 9.10
(other Linux systems I have not tested) because the source of the
content of the combobox is different from the font of the combobox
popup when I can figure out how to fix this bug that makes it
impossible to align multiple fields within the combobox will update
the package. The file can be downloaded at: http://www.liuheschool.com

I forgot that the components are added in Data Controls and I could
not show him the pictures that are inside the file.zip, even though I
followed the thread and to sign documents online!

QuoteI designed two new components,

Sorry if I misunderstood your post.

You designed it?
I dont understand.
You mean you make your own widget code for this component?
Im interested of how you make that component?
Can you share your info in making a component.

I simply inherited classes and then I added carriers in the private
sector, and the functions I've managed. Simple!

Oh, Thank you, you mean to say you've created a new component and want
to share with us. It's called TDBSimple?
I thought your creating a widget.

Thanks, don't delete the link, I'll be glad to test/use it.
