Closing document in Word under Automation

[Dave Loeser]

I'm using Word Automation (using C++ here) as an out of proc exe to Find and Replace text within documents. When I create an instance of Word I would prefer to keep that instance open and then open, search/replace, close and repeat until I am finished with all documents and then quit the word application instance. I have this working but I have an odd (or maybe it is a common) problem. When I close the document, Word becomes visible. Here's how I am closeing the document.

void CMSWord9Automation::CloseDoc()
{
	try
	{
		if(m_pOpenDoc) // Word::_DocumentPtr
		{
			//m_pWord->Visible = VARIANT_FALSE; // Does not work
			m_pWord->Documents->Close(
				&_variant_t(Word::wdDoNotSaveChanges),
				&_variant_t(vtMissing),
				&_variant_t(VARIANT_FALSE));

			//m_pWord->Visible = VARIANT_FALSE; // This resets word to invisible but isn't really the desired approach
			m_pOpenDoc.Release();
		}
	}
	catch(_com_error& ComError) 
	{
		DumpComError(ComError);
	}
}

I'm looking for any information on how to stop Word from displaying when I close the opened document. Thanks, Dave Dak Lozar Loeser When access is allowed to a member, it said to be accessible. Otherwise, it is inaccessible. - MSDN:C# Programmer's Reference
