Hi,
I'm trying to use some power management features with windowsx xp
and I have visual studio .net 2003 installed.
As per documentation of ACPI, you can
use the power options by including the Powrprof.h file and use the
Powrprof.lib file in your project, which I did, but when I build, it
compiles fine but I get this Link error.. :
error LNK2019: unresolved external symbol "long __stdcall
CallNtPowerInfo rmation(enum POWER_INFORMATI ON_LEVE,void*,u signed
long,void*,unsi gnedlong)"
(?CallNtPowerIn formation@@YGJW 4POWER_INFORMAT ION_LEVEL@@PAXK 1K@Z)
referenced in
function _main
fatal error LNK1120: 1 unresolved externals
The code is as shown below :...
Any Ideas on what I'm missing here... please help...
Thanks,
Regards,
AS.
#include "stdafx.h"

I suspect that you need to link against Powrprof.lib.

I am having the same issue. Powrprof.lib is listed in my IDE to be linked.
Any other ideas?
Thanks.

Your problem is that you didn't put the 'extern "C" {}' around the #include<pawrpr of.h>.
I had the same problem and that fixed it.
Good luck!

"A "long" in C is an "int" in C#."
Does this mean that whenever passing a parameter to a C function which
expects a long type, the variable on C# side should be declared as int type?
What if in the following case, should the parameter "level" be type of int
as well?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
