c++ - 初始化 COM 对象/将 VB 代码转换为 C++

Question

有人可以将以下代码翻译成 C++ 吗？这是否可能，或者是否缺少重要信息？

Dim Laser As ObjectSub EnableLaser    ‘ Create a laser object if it hasn’t been done yet    If Laser Is Nothing Then       Set Laser = CreateObject("NWLaserXControl.NWLaserX")    End If    If Laser.Initialize Then       Laser.RepRate = 10 ‘ set the rep rate to 10Hz       Laser.LaserEnabled = True ‘ turn on laser power supply, get it ready    End IfEnd Sub

Answer 1

// if (CoInitialize(0) == S_OK)
{
    CComPtr<INWLaserX> pMyPtr = NULL;

    CLSID clsid = IID_NULL;
    CLSIDFromProgID("NWLaserXControl.NWLaserX");

    if (pMyPtr.CoCreateInstance(clsid) == S_OK)
    {
         pMyPtr->put_RepRate(10);
         pMyPtr->put_LaserEnabled(TRUE);
    }

   // CoUnInitialize();
}
