Detect In-Context Edit Example (C++ COM)

This example shows how to trap an swAssemblyBeginInContextEditNotify event and examine the document being edited in an assembly.

1. Create a new C++ COM add-in with the Visual Studio.NET COM AppWizard.

2. Select Assembly Events on the SwOptions page.

3. After the wizard finishes generating code, add this code to the specified files.

1. swDocument.h:

SINK_ENTRY_EX(ID_ASSEMBLY_EVENTS, __uuidof(DAssemblyDocEvents), swAssemblyBeginInContextEditNotify,OnAssemblyBeginInContextEditNotify)

STDMETHOD(OnAssemblyBeginInContextEditNotify)(LPDISPATCH newDoc, long docType); //

next to the other SINK_ENTRY_EX and STDMETHOD Declarations

2. swDocument.cpp:

STDMETHODIMP CSwDocument::OnAssemblyBeginInContextEditNotify(LPDISPATCH newDoc, long docType)

{

ATLTRACE("\tCCSwDocument::OnAssemblyBeginInContextEditNotify called\n");

CComPtr<IModelDoc2> swModel;

iSwApp->get_IActiveDoc2(&swModel);

CComPtr<IModelDoc2> swNewModel;

newDoc->QueryInterface(__uuidof(IModelDoc2), reinterpret_cast<void**>(&swNewModel));

CComBSTR ContextName;

CComBSTR MainName;

swNewModel->GetTitle(&ContextName);

swModel->GetTitle(&MainName);

CComBSTR message;

message.Append(OLESTR("Main Assembly: "));

message.Append(MainName);

message.Append(OLESTR("     Component: "));

message.Append(ContextName);

long res;

iSwApp->SendMsgToUser2(message,0,0,&res);

return S_OK;

}

4. After loading the add-in, open an assembly, right-click a component, and select Edit Part or Edit Subassembly. The new method OnAssemblyBeginInContextEditNotify that you implemented should be called.
