Hi Fred,

That took a little detective work. I thought you could get this with an
IVsOutputWindow::GetPane call as well, but I found the following comments
in the vsshell.idl file which indicate you should use the
SVsGeneralOutputWindowPane service to get the IVsOutputWindowPane of the
general pane. I haven't tried it myself, but I see code in some of our
components that call QueryService with this, so I suspect that's the way to
go.

//--------------------------------------------------------------------------
--
// interface IVsOutputWindowPane
//--------------------------------------------------------------------------
--
// Implemented by the Environment by the OutputWindow tool window.
// Interface retrieved by IVsOutputWindow::GetPane.
// Used by parties that want to display messages in the OutputWindow. The
OutputWindow
// is an extensible Window, but every OutputWindowPane must have an owner
VsPackage
// that creates the pane via IVsOutputWindow::CreatePane. There are two
standard OutputWindow
// panes owned by the Environment:
//   "Build" -- Projects often display build errors/warnings in the "Build"
OutputWindow pane.
//              This pane is create by the SVsSolutionBuildManager service.
The pointer to
//              the pane is passed to projects as part of
IVsBuildableProjectCfg operations.
//   "General" -- Any party can display miscellaneous informational
messages that occur at any
//              time can be displayed in the "General" OutputWindow pane.
The "General" pane
//              can be retrieved by calling
QueryService(SID_SVsGeneralOutputWindowPane,
//              IID_IVsOutputWindowPane) as a global service.
