Win32 SDK中设置Hotkey

MSDN中的一个示例代码，步骤就是RegisterHotKey注册热键，然后响应WM_HOTKEY消息

@1:这个是系统热键

#include "stdafx.h"

int _cdecl _tmain (
int argc,
TCHAR *argv[])
{
if (RegisterHotKey(
NULL,
1,
MOD_ALT | MOD_NOREPEAT,
0x42))  //0x42 is 'b'
{
_tprintf(_T("Hotkey 'ALT+b' registered, using MOD_NOREPEAT flag\n"));
}

MSG msg = {0};
while (GetMessage(&msg, NULL, 0, 0) != 0)
{
if (msg.message == WM_HOTKEY)
{
_tprintf(_T("WM_HOTKEY received\n"));
}
}

return 0;
}

@2：软件非全局的快捷键，Keyboard Accelerators（键盘加速器）

FontAccel ACCELERATORS
{
VK_F5, IDM_REGULAR, VIRTKEY
"B", IDM_BOLD, CONTROL, VIRTKEY
"I", IDM_ITALIC, CONTROL, VIRTKEY
"U", IDM_ULINE, CONTROL, VIRTKEY

haccel = LoadAccelerators(hinstAcc, "FontAccel");
if (haccel == NULL)

// Get and dispatch messages until a WM_QUIT message is
// received.
