Razzak, last evening I took some time to catch up on postings to rbase_l. I was two weeks behind. Much to my delight, I discovered the "On Key Press" enhancement. Many of my clients are former Quickbooks users and they frequently asked me to duplicate 'fill-in as you type" process that QB uses. Until now, I had to tell them that I could not duplicate the process.
As a test I modified one of my applications to make use of the new feature and I am very impressed with the results. I use the combination of a VAR Edit and a DB Grid to select a customer from a list of 30,000. Much to my surprise, the list in the DB Grid refreshes instantaneously as you type. I thought there would be a delay. It only takes a few lines of code in the EEP to get lightning fast results. I plan to create a proc and call this procedure throughout my applications. THANKS for this very useful enhancement! John -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of A.

R:BASE 7.6 (Build 7.6.3.30404 or higher) for Windows . R:BASE C/S:I 7.6 (Build 7.6.3.30404 or higher) for Windows . R:BASE Turbo (Build 8.0.17.30404 or higher) for Windows Did you know that you can use the new "On Key Press" EEP to execute a defined code while start typing a character in DB Edit or Variable Edit control? Use "On Key Press" EEP, an event handler to make something happen as a result of a single character key press. The Key parameter in the On Key Press event handler is of type TEXT; therefore, the On Key Press event registers the ASCII character of the key pressed. Keys that don't correspond to an ASCII Char value (Shift or F1, for example) don't generate an On Key Press event. Key combinations (such as Shift+A), generate only one On Key Press event (for this example, Shift+A results in a Key value of "A" if Caps Lock is off).
