int BufferLength = 100;
try
{
PtrIMXNamespaceManager.CreateInstance _
(__uuidof(MSXML2::MXNamespaceManager));
PtrIMXNamespaceManager->declarePrefix(_T("sample"),_T("urn"));
hres = PtrIMXNamespaceManager->_getURI(L"sample", NULL, _
WideCharBuffer, &BufferLength);
DisplayMessageToUser(_bstr_t(WideCharBuffer));
PtrIMXNamespaceManager->pushContext();
PtrIMXNamespaceManager->declarePrefix(_T("sample"),_T("urn2"));
BufferLength = 100;
hres = PtrIMXNamespaceManager->_getURI(L"sample", NULL, _
WideCharBuffer, &BufferLength);
DisplayMessageToUser(_bstr_t(WideCharBuffer));
PtrIMXNamespaceManager->popContext();
BufferLength = 100;
hres = PtrIMXNamespaceManager->_getURI(L"sample", NULL, _
WideCharBuffer, &BufferLength);
DisplayMessageToUser(_bstr_t(WideCharBuffer));
}
catch(...)
{
DisplayMessageToUser("Error");
}
}
void DisplayMessageToUser(char *Msg)
{
::MessageBox(NULL, Msg, _T("Message"), MB_OK);
Remarks
The popContext method removes all declarations from the top of the stack down to the declaration prior to the last pushContext method call. If no context is available to pop, popContext returns an error.
