 |
|
I want to like use switch/case on GetASyncKeyState (lazy to start if/else).
i was wondering if i would do it like this ?
| Code: | int vKey = VK_F1 | VK_F2 | VK_F3 | VK_F4;
SHORT lol = GetAsyncKeyState(vKey);
swtch(lol)
{
case VK_F1:
case VK_F2:
//and so on..
} |

No.

Return Value
If the function succeeds, the return value specifies whether the key was pressed since the last call to GetAsyncKeyState, and whether the key is currently up or down. If the most significant bit is set, the key is down, and if the least significant bit is set, the key was pressed after the previous call to GetAsyncKeyState. |

| Call GetAsyncKeyState in a loop or just call RegisterHotKey once.

Isn't the GetAsyncKeyState value cleared after using the code? so when you loop it it'd just...
I'm not experienced at this... :p

| You don't get it. GetAsyncKeyState doesn't return a virtual key code. It returns the state of the key, down or up. It doesn't take an array as a param either.

Read the MSDN entry.
| Quote: | SHORT GetAsyncKeyState
If the function succeeds, the return value specifies whether the key was pressed since the last call to GetAsyncKeyState, and whether the key is currently up or down. If the most significant bit is set, the key is down, and if the least significant bit is set, the key was pressed after the previous call to GetAsyncKeyState. However, you should not rely on this last behavior; for more information, see the Remarks. |
Go look at AX in a debugger if you really care.

Switc( VirtualKey ) {
case 0x41:
MessageBox( NULL, "You pushed A", "message", MB_OK );

Wrong.
GetAsyncKeyState doesn't get the state of the keyboard, it gets the state of a key, you will get compile error/warning. (Use of uninitialized variable)
