Visual Basic

BtnEnh1_KeyDown (KeyCode As Integer, Shift As Integer)


Visual C++

void KeyDown (short KeyCode, short Shift);







A key code, such as vbKeyF1 (the F1 key in VB) or vbKeyHome (the HOME key in VB).


An integer that corresponds to the state of the SHIFT, CTRL, and ALT keys at the time of the event. The shift argument is a bit field with the least-significant bits corresponding to the SHIFT key (bit 0), the CTRL key (bit 1), and the ALT key (bit 2 ). These bits correspond to the values 1, 2, and 4, respectively. Some, all, or none of the bits can be set, indicating that some, all, or none of the keys are pressed. For example, if both CTRL and ALT are pressed, the value of shift is 6.
