How can I remove a MS Word add-in button? - c++

Question

I need to programmatically remove an add-in from MS Word. I have deleted the registry entry corresponding to it, and the button is now disabled (nothing happens when you click it) and the add-in no longer appears on the list of COM Add-ins.
The button, however, remains in the Add-ins ribbon menu. How can I remove that programmatically?

No answers after a week. You can tell its a lazy question, can't you?
I am currently using a solution from CodeProject. My code seems to work, but it has not been tested properly yet.
CoInitialize(NULL);
CLSID clsid;
IDispatch *pWApp, *pCommandBars, *pCommandBar, *pCommandBarControls, *pCommandBarControl;
VARIANT v;
HRESULT hr;
hr = CLSIDFromProgID(L"Word.Application", &clsid);
if (SUCCEEDED(hr))
{
hr = CoCreateInstance(clsid, NULL, CLSCTX_LOCAL_SERVER, IID_IDispatch, (void **)&pWApp);
if (SUCCEEDED(hr))
{
VariantInit(&v);
hr = OLEMethod(DISPATCH_PROPERTYGET, &v, pWApp, L"Commandbars", 0);
pCommandBars = v.pdispVal;
VariantInit(&v);
hr = OLEMethod(DISPATCH_PROPERTYGET, &v, pCommandBars, L"Count", 0);
INT NumCommBars = v.intVal;
for (INT i = 1; i <= NumCommBars; i++)
{
COleVariant CommandBarIndex((BYTE)i);
VariantInit(&v);
hr = OLEMethod(DISPATCH_PROPERTYGET, &v, pCommandBars, L"Item", 1, CommandBarIndex);
if (FAILED(hr)) continue;
pCommandBar = v.pdispVal;
VariantInit(&v);
hr = OLEMethod(DISPATCH_PROPERTYGET, &v, pCommandBar, L"Controls", 0);
if (FAILED(hr)) continue;
pCommandBarControls = v.pdispVal;
VariantInit(&v);
hr = OLEMethod(DISPATCH_PROPERTYGET, &v, pCommandBarControls, L"Count", 0);
if (FAILED(hr)) continue;
INT NumControls = v.intVal;
for (INT j = 1; j <= NumControls; j++)
{
COleVariant CommandBarControlIndex((BYTE)j);
VariantInit(&v);
hr = OLEMethod(DISPATCH_PROPERTYGET, &v, pCommandBarControls, L"Item", 1, CommandBarControlIndex);
if (FAILED(hr)) continue;
pCommandBarControl = v.pdispVal;
VariantInit(&v);
hr = OLEMethod(DISPATCH_PROPERTYGET, &v, pCommandBarControl, L"Caption", 0);
if (FAILED(hr)) continue;
CString ControlCaption(v.bstrVal);
if (ControlCaption.Find("MyCaption") != -1)
{
OLEMethod(DISPATCH_METHOD, NULL, pCommandBarControl, L"Delete", 0);
}
pCommandBarControl->Release();
}
pCommandBar->Release();
pCommandBarControls->Release();
}
OLEMethod(DISPATCH_METHOD, NULL, pWApp, L"Quit", 0);
pCommandBars->Release();
pWApp->Release();
}
}
CoUninitialize();
Hope this helps others with a similar problem.
