SUMMARY
The scan code for the BREAK key is &H46. The CTRL+BREAK keystroke
combination is trapped differently, depending on whether or not the
program is run on a standard or enhanced keyboard.
This information is also included with the Help file provided with the
Standard and Professional Editions of Microsoft Visual Basic for
MS-DOS, version 1.0.
For a standard keyboard, CTRL+BREAK is defined as follows
KEY n, CHR$(&H04) + CHR$(&H46)
where n is in the range 15 through 25.
On an enhanced keyboard, CTRL+BREAK is defined as follows:
KEY n, CHR$(&H84) + CHR$(&H46)
Please note that you must make separate user-defined KEY statements
for trapping CTRL+BREAK in combination with the SHIFT, ALT, NUM LOCK,
and CAPS LOCK keys. The keyboard flags for these other keystroke
combinations must be added together to define a given keystroke
sequence.
Examples of trapping CTRL+BREAK and CTRL+C (when the SHIFT, ALT,
NUM LOCK, or CAPS LOCK keys are NOT active) are included below.
