Path variable to mso.dll and msoutl.olb

Question

Hey,

I'm trying to develop a toolbar for Microsoft Outlook. For getting it to work I need mso.dll and msoutl.olb as an import. My problem is: the path is hardcoded , but it varies for every OS and of course if someone doesn't install Office to the default path.

I tried it this way

but it didn't work, because I couldn't get the return value I needed (OK, after four type conversions but I thought there had to be a better way ;) )

Thanks for helping

The path to MSO.DLL is stored under the following registry key for Office 2007:

HKLM\SOFTWARE\Microsoft\Office\12.0\Common\FilesPaths\mso.dll

The install path is also under this key:

HKLM\SOFTWARE\Microsoft\Office\12.0\Common\InstallRoot\Path
