First - please do NOT press 'enter' at the end of each line. The forum sdoftware DOES know how to 'wrap text'.
Create a form, create a block and use the wizard to access a table in your database (you DO have to be signed in to a database for this to work), in the 'sort by' property add the name of the field(s) you wish to 'sort by', create another block (let's call it 'ctrl', it does NOT access a database table), add one item manually (call it 'srch_txt'), put this field on the canvas on which you placed the database populated block.
Now, using the form builder, move the 'ctrl' block higher up the hierarchy so that it is now the first block. Add a button to the 'ctrl' block and put it next to the 'srch_txt' field. Add a When-Button-Pressed trigger to this button. Put code into this trigger to go to the second block and perform an 'Execute_Query' command.
On your data block add a Post-Query trigger which tests the returned value against the data in 'srch_txt' and if they 'match' use a 'set_item_instance_property' command to change their Visual Attribute name (you will need to have defined a couple of visual attributes, eg. 'normal' and 'highlight').

Upd-Mod: Many typos. Sorry.

| In what way is |
the sample code in the site that you have been suggested is not working
|
The site does not respond or you are using an educational institution's PC and they do not permit downloads by students?
