method executing too many times

[mgriffith]

i have 2 methods that are using IWebBrowser2 to execute a print method from a com object that is hosted on a webpage. here is the code for the methods:

---------------------------------

STDMETHODIMP CTemplatePrinter::IEPrintNoPrompt(VARIANT varTemplateURL)
{
CComPtr<IOleContainer> spContainer;
CComPtr<IServiceProvider> spSP;
CComPtr<IWebBrowser2> spWB;
CComPtr<IDispatch> spDisp;
CComPtr<IHTMLDocument2> spDoc;
CComPtr<IOleCommandTarget> spCT;
CComVariant vPTPath = varTemplateURL;


m_spClientSite->GetContainer(&spContainer);
spContainer->QueryInterface(IID_IServiceProvider, (void**)&spSP);
spSP->QueryService(SID_SWebBrowserApp, IID_IWebBrowser, (void**)&spWB);
spWB->get_Document(&spDisp);
spDisp->QueryInterface(IID_IHTMLDocument2, (void**)&spDoc);
spDoc->QueryInterface(IID_IOleCommandTarget, (void**)&spCT);

// ******* THIS IS WHERE IT'S GOING CRAZY!!!! ******* //
spCT->Exec(&CGID_MSHTML, IDM_PRINT, OLECMDEXECOPT_DONTPROMPTUSER, &vPTPath, NULL);

return S_OK;
}


---------------------------------------

STDMETHODIMP CTemplatePrinter::IEPrint(VARIANT varTemplateURL)
{
CComPtr<IOleContainer> spContainer;
CComPtr<IServiceProvider> spSP;
CComPtr<IWebBrowser2> spWB;
CComPtr<IDispatch> spDisp;
CComPtr<IHTMLDocument2> spDoc;
CComPtr<IOleCommandTarget> spCT;
CComVariant vPTPath = varTemplateURL;


m_spClientSite->GetContainer(&spContainer);
spContainer->QueryInterface(IID_IServiceProvider, (void**)&spSP);
spSP->QueryService(SID_SWebBrowserApp, IID_IWebBrowser, (void**)&spWB);
spWB->get_Document(&spDisp);
spDisp->QueryInterface(IID_IHTMLDocument2, (void**)&spDoc);
spDoc->QueryInterface(IID_IOleCommandTarget, (void**)&spCT);

// ***** IT CALLS THIS 2 TIMES? ******** //
spCT->Exec(&CGID_MSHTML, IDM_PRINT, OLECMDEXECOPT_PROMPTUSER, &vPTPath, NULL);

return S_OK;
}
--------------------------

my question is: does anyone have any idea why the IOleCommandTarget::Exec method it going berzerk? when i call the method from a script, the first one keeps spooling pages into the printer, and the second one opens 2 print dialogs in a row...i also have another function for opening a print preview window that works fine....the only difference is my call to Exec is as follows:
spCT->Exec(&CGID_MSHTML, IDM_PRINTPREVIEW, OLECMDEXECOPT_PROMPTUSER, &vPTPath, NULL);

i've tried all that i can see...if i replace spCT->Exec(...) with
spWB->ExecWB(OLECMD_PRINT, OLECMDEXECOPY_PROMPTUSER, &vPTPath, NULL);
it still does the same thing...i've even tryied without passing in the &vPTPath (printing template path) argument

i also know that the method is only getting called once...i tested this by also using spDoc to write some stuff out to pop up a message box every time it got called, and the message box only came up once, but the printing kept going...

any suggestions?
