int VkKeyScan (cChar)
This function translates an ANSI character to the corresponding virtual-key code and shift state for the current keyboard. Applications which send character by means of WM_KEYUP and WM_KEYDOWN messages use this function.
| Parameter | Type/Description |
| cChar | char Specifies the character for which the corresponding virtual-key code is to be found. |
The VK_ code is returned in the low-order byte and the shift state in the high-order byte. The shift states are:
| Value | Meaning |
| 0 | No shift. | |
| 1 | Character is shifted. | |
| 2 | Character is control character. | |
| 6 | Charcter is CONTROL+ALT. | |
| 7 | Character is SHIFT+CONTROL+ALT. | |
| 3, 4, 5 | A shift key combination that is not used for characters. |
If no key is found that translates to the passed ANSI code, a –1 is returned in both the low-order and high-order bytes.
Translations for the numeric keypad (VK_NUMPAD0 through VK_DIVIDE) are ignored. This function is intended to force a translation for the main keyboard only.
