代码注册COM组件

在代码里注册COM组件，相对于regsvr32有自己的优点，可控，隐蔽性好。这里将msdn的示例修改了下：

需要注意的有两点:

1. Ole环境的初始化和释放;
2.    GetProcAddress中的函数名称，这里需要取得函数地址，所以函数名大小写...不能写成DllUnRegisterServer

	HRESULT hr = OleInitialize(NULL);
<span style="white-space:pre">	</span><pre name="code" class="html"><span style="white-space:pre">	</span>int iError;

HINSTANCE hLib = LoadLibrary(_T("XXX.dll"));if (hLib < (HINSTANCE)HINSTANCE_ERROR){iError = GetlastError();

<span style="white-space:pre">		</span>return iError<span style="font-family: Arial, Helvetica, sans-serif;">;</span>
	}

	// 注册
	FARPROC lpDllEntryPoint = GetProcAddress(hLib,"DllRegisterServer");
	FARPROC lpDllEntryPoint = GetProcAddress(hLib,"DllUnregisterServer");

	if (lpDllEntryPoint != NULL)
		(*lpDllEntryPoint)();
	else
	<span style="font-family: Arial, Helvetica, sans-serif;">{</span><pre name="code" class="html">		iError = GetlastError();

<span>		</span>return iError<span style="font-family: Arial, Helvetica, sans-serif;">;</span>
	}

::FreeLibrary(hLib);OleUninitialize();
