问题描述
我正在尝试实施
GetSaveFileName()不返回路径XP上的CD刻录暂存区
我正在尝试在VS2008 C ++中实现这一点. ICDBurn :: GetRecorderDriveLetter()方法不是静态的，因此不能按上述答案中的书面形式( ICDBurn :: GetRecorderDriveLetter )进行调用. ICDBurn无法实例化，因为它是一个抽象类.如何从C ++调用 ICDBurn :: GetRecorderDriveLetter()?
I'm trying to implement this in VS2008 C++. The ICDBurn::GetRecorderDriveLetter() method is not static and thus cannot be called as written (ICDBurn::GetRecorderDriveLetter) in the above answer. ICDBurn can't be instantiated because it's an abstract class. How do I call ICDBurn::GetRecorderDriveLetter() from C++?
推荐答案
您需要先创建COM对象.
You need to create the COM object first.
ICDBurn* pICDBurn;
HRESULT hr = CoCreateInstance(CLSID_CDBurn, NULL,CLSCTX_INPROC_SERVER,IID_ICDBurn,(LPVOID*)&pICDBurn);
if (SUCCEEDED(hr))
{
// do something ...
pICDBurn->Release();
}
