vuPasswordCleanup(ControlHandle)

vuPasswordCleanup(LONG InHwnd),SIGNED,PROC,PASCAL,RAW,NAME('vuPasswordCleanup')

Description

Manually detaches the managed password helper from a Clarion entry control.

This function performs deterministic cleanup for one control by:

removing the generated eye button
restoring the original subclass chain for that control when appropriate
releasing the helper state associated with that control

While Windows often tears this down automatically when a window closes, this function gives the developer a predictable cleanup option during normal window shutdown.

Parameters

Parameter	Data Type	Description
InHwnd	LONG	Handle of the target control previously initialized with `vuPasswordInit()`.

Returns

1 = Cleanup successful
-5 = Control was not initialized

Example

RC LONG

RC = vuPasswordCleanup(?MyPassword{PROP:Handle})

Notes

This function is optional, but recommended when you want deterministic cleanup during window teardown.
A good place to call it is during your window shutdown logic.
After cleanup, the control is no longer managed by the password helper until vuPasswordInit() is called again.
