| Summary | 0005049: TJvCpuUsage.Usage always returns 0 under Windows 7 x64 | ||||
| Description | TJvCpuUsage.Usage always returns 0 under Windows 7 x64. | ||||
| Additional Information | The x86 Edition of Windows 7 does not seem to be affected, but all other 64Bit Windows editions seem to be affected. The call that fails is: Status := NtQuerySystemInformation(SystemPerformanceInformation, @SysPerfInfo, SizeOf(SysPerfInfo), nil); | ||||
| Tags | No tags attached. | ||||

Does this also happen in XP x64? |
|
|
I tested a little more and found out that only Windows 7 x64 seems to be affected, but not XP64 or Vista64. |
|
|
Thanks for the report. As I do not have access to Seven (either x86 or x64), someone else will have to look at that. |
|
|
This is confirmed in Seven x64 NtQuerySystemInformation is "undocumented" and so I'm not suprised of it not working. Need to find another solution. |

|
This should now be fixed in SVN, please try using the latest version |
