Embarcadero Edition and its VCL components

Hi all,
I got some Reports working with FR in my Delphi XE3. Everything is fine, if it's a simple report, that goes through a Dataset and generates similar output for every record.

But now I've got a report, that displays the content of a variable in a barcode. It uses a Variable because the barcode is used in the header to identify the report itself.
Sometimes the barcode value is empty and should not be printed. If the variable is empty, the report generates an error: Error in Expression '' Expression expected.

How can I disable the Barcode object from my delphi code for occasions, where the Barcode is empty? Since I have the Embarcadero Edition, I can't script in the report itself.

BTW: What is the TfrxBarcodeObject for and how can I use it? (Same for all the other Tfrx<xxx>Object components)?
They have no published properties and Code Insight doesn't show any properties or methods that are self explaining either.
Does any documentation exist about the Tfrx Components (first of all TfrxReport) aside from building reports in the FastReport Editor?
A description (maybe examples) of all published and public properties as well as public and protected methods?

I googled quite a while, but all I found was about scripting FR or building reports inside the FR editor. >[img]style_emoticons/<#EMO_DIR#>/unsure.gif" style="vertical-align:middle" emoid=":unsure:" border="0" alt="unsure.gif" /> Thanks in advance for any help. Lutz Kutscher[/img]

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
