Last week, I was in Nevada working on a project. Everything was going great except that the comboboxes were not responding to the valid events I had put in them. It was strange... If I dropped down the list, the valid event would fire and thus the system could control the data. However, if I typed in a few characters, found the line I wanted and then hit [enter], the combobox valid event didn’t fire. Worse, if the box was empty and I had a valid event preventing empties, I could bypass the valid event by using the mouse or the tab key.

It turns out that the comboboxes valid events are not fired when the user exits the object with a mouse click or the tab key. So... How do you get around this problem? Easy, you just “tire” the valid event from the lost focus event. The only downside of this technique is that if the valid event is complex, it will get executed twice. Below is the example code. Note the use of NODEFAULT in the lost focus method. This code prevents the user from moving to the next object.

RETURN (NOT EMPTY(THIS.value))

Ireturn = THIS.valld()

It Can’t Get Any Easier.......
