Defining The Keys
98 8580/8590 Vehicle-Mount Computer User Manual
At present, only one basic key code can be set for each key; in combination with
[SHIFT]+[ALT Gr], this then automatically gives the other assignments. Therefore,
for the key code E, the euro symbol € is automatically produced with the [ALT Gr]
key pressed.
The virtual-key code names can be obtained from Microsoft MSDN (Microsoft
Developer Network).
Examples:
e/E/€|E
Assignment of label and code = E to a key
For the assignment of the standard ASCII characters, no special vir-
tual-key code is necessary; the character can be specified directly as a
code.
$BMP_Return|VK_RETURN
Assignment of bitmap and virtual-key code name to the <Return> key
,/;/|VK_COMMA
Assignment to a standard comma key
As an alternative to the virtual-key code, the numerical scan code of a key can also
be entered directly. This is made possible through the # character.
If, for example, you want to specify the scan code of the [ESC] key, you must
specify the value #1 in the VirtualKeycode field; for the A key, you must specify
the value #30.
This is necessary in particular for keys with national special characters, since no
virtual-key code definitions generally exist for these keys.
Key Codes For Special Functions
VK_KB_UPDOWN
This key code is not used as a keyboard value, but instructs the program
internally to change the keyboard position (from bottom edge to top
edge, and vice versa).
VK_KB_SWITCHNEXT
Keys with this key code cause a switch to the next defined software
keyboard. See also the ExcludeChain parameter.
