'get key input when more than four keys are being
'pressed? With this API it is no longer a problem!
'This is a short sample that gets the state of any key
'on the keyboard. The numbers passed in are the same as
'the keycodes in Form_KeyDown. You can look these up by
'typing "key code constants" in the VB help. The return
'values are sort of weird. At the beginning, the value
'of an unpressed key is 0, if it is held down after that,
'the value is -127, unpressed again is 1, and the second
'pressed value is -128. This cycle then repeats itself.
Dim RetValue As Long
Dim SendKeyCode As Long
SendKeyCode = 37 'Left key
RetValue = GetKeyState(SendKeyCode)
Print RetValue
