DisplayURLIsValid Property

This read-only, Boolean property indicates whether the specified location

of the FactoryTalk Historian ProcessBook display file is valid. If so, it

returns TRUE.

ReadyState Property

The read-only ReadyState property indicates the state of the control. The

possible states are:

State

Value

Description

pbReadyStateLoading

The control is being constructed. Once its

window is created, it becomes interactive.

pbReadyStateInteractive

FactoryTalk Historian ActiveView is loading

the display.

pbReadyStateComplete

The display is viewable.

These state transitions trigger the ReadyStateChange stock event.

Developers must use the integer values for these constants or to define them

within scripts. You can also look up these values in the Visual Basic Object

Browser.

ServerIniURL Property

The ServerIniURL property, which is optional, specifies the location of a

pilogin.ini file that contains Historian Server information.

This property also supports relative paths; however the first time the

control's ServerIniURL property is set, you must specify the absolute path.

After that, you may specify a ServerIniURL that is relative to the initial

path. The protocol may or may not be specified in the relative path. Note

that specifying a different protocol in the relative path is invalid. Also, the

property always returns the absolute path.
