Can't compiling when using HW_PROFILE_INFO of GetCurrentHwProfileA SDK function

[DidierR]

Hello,

I've add a SDK function in an old program under CVI 9.0 and Windows 7.

This function is GetCurrentHwProfileA (or without A at the end of the name).

I've write Microsoft sample in a file to my project.

HW_PROFILE_INFO profil;    
 GetCurrentHwProfile(&profil);
 

The problem is that HW_PROFILE_INFO structure is not found by the compiler.

I got error message: "Undeclared identifier 'HW_PROFILE_INFO' even if I've add winbase.h after Windows.h header. winbase.h already existes in the "\National Instruments\CVI90\sdk\include\" folder.

Util.c - 4 errors
 126, 1   Undeclared identifier 'HW_PROFILE_INFO'.
 126, 17   syntax error; found 'identifier' expecting ';'.
 126, 17   Undeclared identifier 'profil'.
 127, 5   Missing prototype.

I tried to add recommanded macro /D_WIN32_WINNT=_WIN32_WINNT_WIN7, but without any sucess.

Is there somebody to help me and tell me what to do to solve this issue?

Best regards.

Didier

I'm afraid CVI 9.0 has an older Windows SDK that doesn't know about _WIN32_WINNT_WIN7. Try using 0x0601 instead

/D_WIN32_WINNT=0x0601

Thank you ConstantinP.

That compiles now and I get what I wanted. However this generates warnings at winbase.h that I would like to avoid.

 "WinBase.h"(1630,1)   Warning: Static '__int64 function(pointer to volatile __int64,__int64) InterlockedAnd64' is not referenced.

#if (_WIN32_WINNT >= 0x0502)

I've tried with /D_WIN32_WINNT=0x0501 and warnings have been cleared.

Can this solution affect the rest of my program? Do you think it is a good solution?

Setting _WIN32_WINNT to 0x0501 should be OK. If the value is lower you cannot use some features, like it was with GetCurrentHwProfile when _WIN32_WINNT was not defined. You'll know if you need a higher version when you need to use something and you get errors like it was with the initial issue

Thank you for this explanation. I keep this solution.
Best regards.
