OemKeyScan
The OemKeyScan function maps OEM ASCII codes 0 through 0x0FF into the OEM scan codes and
shift states. The function provides information that allows a program to send OEM
text to another program by simulating keyboard input.
DWORD OemKeyScan(
WORD wOemChar
| // ASCII value of OEM character
| );
|
|
Parameters
wOemChar
Specifies the ASCII value of the OEM character.
Return Values
If the function succeeds, the low-order word of the return value contains the
scan code of the given OEM character, and the high-order word contains the
shift state, which can be a combination of the following flag bits:
Bit
| Meaning
| -
| Either SHIFT key is pressed.
| -
| Either CTRL key is pressed.
| 4
| Either ALT key is pressed.
|
If the character cannot be produced by a single keystroke using the current
keyboard layout, the return value is 0xFFFFFFFF.
Remarks
This function does not provide translations for characters that require CTRL+ALT or dead keys. Characters not translated by this function must be copied by
simulating input using the ALT+ keypad mechanism. The NUMLOCK key must be off.
This function does not provide translations for characters that cannot be
typed with one keystroke using the current keyboard layout, such as characters with
diacritics requiring dead keys. Characters not translated by this function may
be simulated using the ALT+ keypad mechanism. The NUMLOCK key must be on.
This function is implemented using the VkKeyScan function.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
