How to compile C code for an Excel XLL in Visual Studio 2008 so it runs on Office 2010 64 bit version -


i have excel add-in developed using excel 2007 sdk, works fine on excel 2007 , excel 2010 32 bit version

more noticed office 2010 or excel 2010 made available 64bit software compared 32 bit version in excel 2007 , counterpart in excel 2010

i understand require excel 2010 sdk , visual studio 2008 able compile xll 64bit version run in excel 2010 64 bit on win7

are there specific options need set in visual studio 2008 can compile code 64 bit version

i looked @ sample code in excel 2010 sdk , uses same xloper12 data type , example code looks quite 1 samples in excel 2007 sdk

this leads me ask whether code previous version require changes before run in 64bit excel environment

many in advance

if code compiles - should go. said - if doing pointer arithematic xloper12s - of course need keep in mind pointers 8 bytes in 64 bit build.

also - if dynamically linking crt make sure provide redistributable. alternatively - statically link 64 bit crt.
