DEVICES
From QB64 Wiki
The _DEVICES function returns the number of INPUT devices on your computer including keyboard, mouse and game devices.
- device_count% = _DEVICES
- Returns the number of devices that can be listed separately with the _DEVICE$ function by the device number.
- Devices include keyboard, mouse, joysticks, game pads and multiple stick game controllers.
- Note: This function MUST be read before trying to use the _DEVICE$, _DEVICEINPUT or _LAST control functions!
Example: Checking for the system's input devices.
devices = _DEVICES 'MUST be read in order for other 2 device functions to work! PRINT "Number of input devices found ="; devices FOR i = 1 TO devices PRINT _DEVICE$(i) PRINT "Buttons:"; _LASTBUTTON(i) NEXT
Number of input devices found = 2 [KEYBOARD][BUTTON] Buttons: 512 [MOUSE][BUTTON][AXIS][WHEEL] Buttons: 3
- Note: The STRIG/STICK commands won't read from the keyboard or mouse device the above example lists.
