Returns the class ID of the run-time object corresponding to the design-time control.
Visual Basic Syntax
Not needed in Visual Basic.
Visual C++ Syntax
HRESULT GetRuntimeClassID(CLSID *pClsid);
Parameter
pClsid
[out] CLSID of the run-time object created by the ActiveX designer.
Return Values
The return value obtained from the returned HRESULT is one of the following:
| Return Value | Meaning |
| S_OK | Success. |
| E_FAIL | The method failed for an unknown reason. |
| E_NOTIMPL | The run-time and design-time objects are the same. |
Remarks
The host calls GetRuntimeClassID to get the CLSID of the run-time object. The CLSID is also marked in the registry entry for the ActiveX designer under the Instance CLSID heading. Typically DTCs have no run time object, so use E_NOTIMPL.
Visual C++ Example
In the following example, the CLSID is retained as a constant and returned upon request through GetRuntimeClassID:
STDMETHODIMP CMyDesigner::GetRuntimeClassID(CLSID *pclsid)
{
return E_NOTIMPL;
}
