Office XP PIA
Posted by Rich B at 6/30/2005 2:24:01 AM
Hi,

Every time I add a reference to Excel in my project, the path shows
that the gac version isn't being used.
Any ideas on where I go from here?

project property pages, can I also use this class in .NET w... more >>
Unmanaged DLL lifetime

When a managed DLL makes a call to an unmanaged DLL what controls the
lifetime of the unmanaged DLL? I am assuming when I make the first call to
an unmanaged DLL, the unmanaged DLL is loaded into memory and stays in memory

Office PIA:s. Can they be made to work properly?
Posted by KennethBohman at 6/29/2005 5:05:02 AM
Hi everybody,

spreadsheet, stopped reading the spreadsheet after the client upgraded from

Hi all,
We use a Microsoft Business Solutions Application - Great Plains. This has a
proprietary language for development - Dexterity/Sanscript.
From Sanscript we can register a call back as an object on the ROT.
From C# I can get access to the running object (Marshal.GetActiveObject) but... more >>
