我已經通過windows WMI實現了一個遠程hyper-v管理類,但是對於ENTER鍵,keycode是什麼。
該方法是「PressKey」,類是Hyper-V WMI類中的Msvm_Keyboard類。
示例代碼是PressKey method of the Msvm_Keyboard class
上面示例中的ENTER鍵的第二個參數是什麼?
根據Virtual-Key Codes table它必須是「0」或「0x0D」,但它們都不被這個樣本接受!什麼是ENTER鍵的虛擬鍵碼?
示例代碼:
class PressKeyClass
{
static ManagementObject GetComputerKeyboard(ManagementObject vm)
{
ManagementObjectCollection keyboardCollection = vm.GetRelated
(
"Msvm_Keyboard",
"Msvm_SystemDevice",
null,
null,
"PartComponent",
"GroupComponent",
false,
null
);
ManagementObject keyboard = null;
foreach (ManagementObject instance in keyboardCollection)
{
keyboard = instance;
break;
}
return keyboard;
}
static void PressKey(string vmName, int keyCode)
{
ManagementScope scope = new ManagementScope(@"root\virtualization", null);
ManagementObject vm = Utility.GetTargetComputer(vmName, scope);
ManagementObject keyboard = GetComputerKeyboard(vm);
ManagementBaseObject inParams = keyboard.GetMethodParameters("PressKey");
inParams["keyCode"] = keyCode;
ManagementBaseObject outParams = keyboard.InvokeMethod("PressKey", inParams, null);
if ((UInt16)outParams["ReturnValue"] == ReturnCode.Completed)
{
string.Format("Key {0} was pressed on {1}", keyCode, vm["ElementName"]);
}
else
{
string.Format("Unable to press key {0}' on {1}", keyCode, vm["ElementName"]);
}
inParams.Dispose();
outParams.Dispose();
keyboard.Dispose();
vm.Dispose();
}
static void Main(string[] args)
{
if (args != null && args.Length != 2)
{
Console.WriteLine("Usage: PressKey vmName keyCode");
return;
}
string vmName = args[0];
int keyCode = int.Parse(args[1]);
PressKey(args[0], keyCode);
}
}
你是什麼意思「不可接受的樣本」?你是否遇到編譯器錯誤或運行時問題? –
只需將常量'VK_RETURN'放在那裏,並告訴我們什麼不起作用。 –
