msdn索引中键入Virtual-Key Codes

你可以添加一个wm_char的消息相应函数,当有按键输入时,他会传来一个字符,然后你可以看看他传来的这个字符的asc2码是多少,就可以判断了!!!

MSDN is very important!!!!!!!!!

//full表示计算全部的Control, Shift , Alt 按键状态，否则仅仅从lParam计算
HOOKAPI(void) GetKeyInfo(WPARAM wParam, LPARAM lParam,KEYINFO *pKeyInfo, BOOL full)
{
    GetKeyNameText(lParam, pKeyInfo->KeyName, sizeof(pKeyInfo->KeyName));
    pKeyInfo->KeyName[sizeof(pKeyInfo->KeyName)-1] = 0;

    pKeyInfo->RepeatCount = (WORD)(lParam & 0xffff);
    pKeyInfo->OEMScanCode = (WORD)((lParam & 0xff0000) >> 16);
    pKeyInfo->Extended      = ((lParam >> 24) & 1)==1;
    pKeyInfo->AltDown      = ((lParam >> 29) & 1)==1;
    pKeyInfo->PreviousDown= ((lParam >> 30) & 1)==1;
    pKeyInfo->Down          = ((lParam >> 31) & 1)==1;    //扩充内容如下
    pKeyInfo->ScanCode      = (WORD)wParam;
    if(full)
    {
        //以下得到扩充的Shift和Control状态
        pKeyInfo->ShiftDown   = ((GetKeyState(VK_SHIFT) & 0xff00) >> 8) == 0x00ff;
        pKeyInfo->ControlDown = ((GetKeyState(VK_CONTROL) & 0xff00) >> 8) == 0x00ff;
    //    pKeyInfo->AltDown     = ((GetKeyState(VK_MENU) & 0xff00) >> 8) == 0x00ff;        //以下根据键状态计算vFlag，vFlag和vKey正好对应CHotKeyCtrl中的对应值
        pKeyInfo->vFlag          = 0;
        if(pKeyInfo->Extended )        pKeyInfo->vFlag |= HOTKEYF_EXT;
        if(pKeyInfo->AltDown )        pKeyInfo->vFlag |= HOTKEYF_ALT;
        if(pKeyInfo->ControlDown)    pKeyInfo->vFlag |= HOTKEYF_CONTROL;
        if(pKeyInfo->ShiftDown )    pKeyInfo->vFlag |= HOTKEYF_SHIFT;
    }
}以上函数中的wParam和lParam分别是键盘消息中的wParam和lParam
