Writing a Performance Monitor
The System Monitor utility is well known to developers on Windows 95 and
Windows 98. This utility can display various system performance statistics,
such as page fault rate and CPU utilization. Applications such as Norton
Utilities contain similar performance monitors of their own.
So, how can you incorporate performance monitoring in your own applications or
custom controls? All you need to do is read the registry. When a Windows device
driver loads, it can define any number of statistics that are updated in the
registry.

reasons. Unfortunately, VCL doesn't provide built-in support for mail services. Instead,
ActiveX controls are provided for this purpose. The ActiveX controls differ
between C++Builder 1.0 and C++Builder 3.0. This article will show you how to
send mail from your applications, whether you're using C++Builder 1.0 or 3.0.
