I'm looking to build a little tool that shows disk I/O in Windows (or
even cross-platform if possible).

I've found this page
(https://code.msdn.microsoft.com/windowsapps/Disk-Activity-Task-bar-
af8ae245) which describes using PerformanceCounters to do this, but I
can't find an equivalent in Lazarus.

Thanks,

Dan

I don't know. Try to write yourself, using WinApi.

Sorry, I should have been clearer in my question... I wasn't looking
for equivalent sample code (I am planning to try writing equivalent
sample code myself).

What I am looking for is an equivalent library for FPC/Lazarus that
would allow me to access the Windows PerformanceCounters.

I guess from your reply that WinApi is the way to go, but I can't find
any calls that seem equivalent to the ones used in the VB sample code,
for example:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
PerformanceCounterCategory.Exists("LogicalDisk")ReadCounter = New
PerformanceCounter("LogicalDisk", "Disk Read Bytes/sec", "_Total")R =
ReadCounter.NextValue
Sorry, my original question was pretty badly written.

Try this https://tondrej.blogspot.com/2004/09/perfmon-ready.html
It is for Delphi but in mode delphi there is no reason it should not
work. (D7 is 99.9% compatible )
