Execution Control and Environment

This page explains the execution-control and environment-management members of cPerformanceManager.

These members are not the primary elapsed-time measurement API. Instead, they control:

• short pauses and waiting strategies
• explicit cleanup of environment changes made by the class
• safe object-lifecycle patterns when using timer-resolution changes or shared TW participation

Members covered here

• Pause
• ResetEnvironment

Pause

Pause delays execution for a requested duration using one of several strategies:

cPM.Pause dSeconds, [iMethod]

Supported pause methods:

• 1 = Sleep API
• 2 = Timer + DoEvents loop
• 3 = Application.Wait
• Else = Now + DoEvents loop

Pause is a utility. It is not a precision scheduler.

ResetEnvironment

ResetEnvironment is the explicit cleanup routine:

cPM.ResetEnvironment

It currently handles:

• timer-resolution cleanup for method 3 when relevant
• shared TW cleanup if this instance is participating

Best practice

Treat ResetEnvironment as the main cleanup contract. Treat Class_Terminate only as a fallback safety net.
