Migrating from VS2005 to VS2010

After migrating a project from VS 2005 to VS 2010, we got the following errors related to include fils of Visual Studio, can anyone provide inputs on solving these? Thanks in advance.

1) error C3861: '_beginthreadex': identifier not found c:\program files (x86)\microsoft visual studio 10.0\vc\atlmfc\include\atlbase.h

_beginthreadex is defined in c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\process.h, even after including this file, the same error is coming.

2) error C2664: 'ATL::ChTraitsOS::GetStringTypeExW' : cannot convert parameter 5 from 'unsigned __int64 *' to 'LPWORD' c:\program files (x86)\microsoft visual studio 10.0\vc\atlmfc\include\atlstr.h

The following is definition of the function in the same file: static BOOL GetStringTypeExW( In LCID lcid, In DWORD dwInfoType, _In_count_(nLength) LPCWSTR pszSrc, In int nLength, Out LPWORD pwCharType)

As these errors are related to Visual studio include files, I have tried changing project related se开发者_如何学JAVAttings, but nothing is working and the errors are still existing.
