KeyPress(KeyAscii)

Occurs when an E3Alarm has the keyboard focus and users press a key corresponding to a character that can be displayed on screen, that is, an ANSI key with a code indicated by the KeyAscii parameter. This event occurs when one of the following keys is pressed:

•Any keyboard character that can be printed

•The CTRL key combined with any standard alphabet character

•The CTRL key combined with any special character

•The BACKSPACE key

•The ESC key

This event does not occur in the following conditions:

•By pressing the TAB key

•By pressing the ENTER key

•By pressing the DEL key, which is not an ANSI key

•By pressing keyboard arrow keys

•When a key moves the focus from one object to another

While users press a key that produces an ANSI code, E3Alarm receives the KeyDown and KeyPress events repeatedly. When users release that key, the KeyUp event occurs. To monitor keyboard physical status or to handle keys not recognized by the KeyPress event, such as function or browsing keys, use the KeyDown and KeyUp events.
