LabWindows/CVI Tip: Using the Windows 8.1 SDK

[TheNIDragon]

Summary

The Windows 8.1 SDK upgrade came with a host of benefits to Windows developers and can be easily enabled for use with LabWindows/CVI. The upgrade provides new functions for handling processes and threads (e.g. SetProcessInformation/GetProcessInformation), an Operation Recorder to speed up repeated file accessing, and better virtual and physical memory handling.

Note: This tip will only work on machines running the Windows 8 operating system or newer

Enabling the Windows 8.1 SDK

In order to use the new features from the SDK, two defines need to be added to the CVI project:

• _WIN32_WINNT=_WIN32_WINNT_WIN8
• WINVER=_WIN32_WINNT_WIN8

These can be added in the Options»Build Options»Compiler Defines field.

Examples for Windows 8.1 SDK

Two examples were shipped with LabWindows/CVI 2015 that show how to use the SDK functionality:

• OperationRecorder.cws
  • Illustrates the use of the Windows SDK feature that allows sped up repeat file access operations.
• SetProcessInfo.cws
  • Illustrates the use of the Windows SDK functions SetProcessInformation and GetProcessInformation for setting and retrieving the memory priority of a process.

Hi,

Did as requested above but got this run error, what have I missed out?

You're using Windows 7, so it' absolutely normal you can NOT use any API

present only in newer versions of Windows.

Hi Srm27,

carlox is right, because the entry point of the Windows DLL changed that the SDK was using, this specific tip only works with the Windows 8 operating system or newer. I should have clarified that in the description, my apologies!
