VB怎么监测指定进程的CPU占用率?

看了很多网页,都没完全的答案,各位有会的吗?菜鸟不懂呀. --------------------编程问答-------------------- http:\\hi.csdn.net\Veron_04 --------------------编程问答-------------------- 楼上的,你那连接啥也看不到 --------------------编程问答-------------------- bs在技术贴灌水的

Public Function GetCPUTemp() As Double
          Dim i     As Integer
          Dim mCPU     As Variant
          Dim u     As Variant
          Dim s     As String
            
          Set mCPU = GetObject("WINMGMTS:{impersonationLevel=impersonate}!root\wmi").ExecQuery("SELECT   CurrentTemperature   From   MSAcpi_ThermalZoneTemperature")
          For Each u In mCPU
                  s = s & u.CurrentTemperature
          Next
            
          Set mCPU = Nothing
            
          GetCPUTemp = (s - 2732) / 10
            
End Function

有详细点的代码吗? 怎么是报错误了? --------------------编程问答--------------------

他那是获取CPU温度的,不是CPU占用率。 --------------------编程问答-------------------- 获取总的CPU占用率,网上有现成的VB例子,就不说了。
如何实时获取系统每个进程占用的CPU使用率(这是C++的,有谁把翻译成VB6就好了):

哎....怎么是C++的,VB就没办法了吗? --------------------编程问答--------------------

每个进程的时间和CPU总时间可以获得,然后计算一下比例.如果动态的话在Timer中执行.

函数定义:

int Button2Click(int id);//参数是进程ID

函数实体:
int Button2Click(int id)
{

DWORD dwInfoSize = 0x20000;
PPROCESSINFO pProcessInfo;

}


控制台调用:
int main(void)
{
 while(true)
 {
  int s = Button2Click(0);//在此把进程ID作为参数传入
  printf("%d\n",s);
  Sleep(1000);
 }
 return 0;
}
