通常,将从 DllUnregisterServer 调用此方法。 以下示例代码可以放入 DllUnregisterServer 的代码中。

ITPluggableTerminalClassRegistration* pTerminal;

BSTR bstrTerminalSuperclass = SysAllocString(L"{F7438990-D6EB-11d0-82A6-00AA00B5CA1B}");

// If (NULL == bstrTermSuperclass) process the error here.

BSTR bstrTerminalClass = SysAllocString(L"{AED6483E-3304-11d2-86F1-006008B0E5D2}");

// If (NULL == bstrTerminalClass) process the error here.

HRESULT hr;
hr = CoCreateInstance( 
    CLSID_PluggableTerminalRegistration,
    NULL,
    CLSCTX_INPROC_SERVER,
    IID_ITPluggableTerminalClassRegistration,
    (void**)&pTerminal);

hr = pTerminal->put_TerminalClass( bstrTerminalClass );
// If (hr != S_OK) process the error here. 
hr = pTerminal->Delete( bstrTerminalSuperclass );
// If (hr != S_OK) process the error here. 

// Release the memory created by SysAllocString().
SysFreeString(bstrTerminalClass);
SysFreeString(bstrTerminalSuperclass);
