Parameters

pbstrDefBrowserPath

pfIsSystemBrowser

Remarks

COM Signature

From vsshell.idl:

HRESULT IVsUIShellOpenDocument::GetFirstDefaultPreviewer(
   [out] BSTR *pbstrDefBrowserPath,
   [out] BOOL *pfIsInternalBrowser,
   [out] BOOL *pfIsSystemBrowser
);

This method returns the same browser that would have been launched if OSP_LaunchSingleBrowser were passed to OpenStandardPreviewer. If it is the internal browser, pbstrDefBrowserPath is nulla null reference (Nothing in Visual Basic), *pfIsInternalBrowser is true, and the function returns S_OK.
