Object Pm

Description:

Global object in the PROMOTIC system accessible by the Pm name.

The basic concept of VBScript and JavaScript languages makes them ideal for safe programming. For example the standard functions of the VBScript language include powerful instruments for algorithm creation, but do not offer any means cor connection with hardware environment. For example these do not allow writing to or reading disk, setting time, control I/O units, etc.
The best approach how to upgrade the JavaScript/VBScript language by functionality that language functions don't have, is to create objects that have the required properties and methods.
In the PROMOTIC system there is a large number of such objects (so-called Pma objects) that enable an access to databases, access for serial link and for Ethernet, calling of a DLL connection, etc.
By calling methods over the Pmg object we usually accomplish the status change of the concrete object (of this instance). It means that methods of these objects don't have global character.
In the PROMOTIC system there is one global object accessible directly from any hierarchical level of the tree. This object is accessible in the script by the "Pm" variable (i.e. calling in the script it is Pm.MethodName). The Pm object contains properties and methods that extend the functions set, for example, by writing to disk, time setting, data setting, etc.

History:

Pm9.00.05: InfoLogReg and InfoLogAdd new methods: Methods allow registering a new item into the INFO system and then adding new entries into item. This is generalization of the Pm.Debug method for user defined logging.

Pm8.02.04: New constants were added that are used for mathematic calculations: PI, E, SQRT2, LN10, LN2, LOG10E and LOG2E.

Pm8.02.01: Many new methods were added that replace the original VBScript methods. These new methods are functional also in Web panels (Javascript and VBScript). The new methods are:

- ToNumber, IsValid, GetVarType

- StringFind, StringFormat, StringLen, StringSplit, StringSub, StringCodeAt, StringCodeFrom

- Random, Sign, Sqrt, Pow, Sin, Cos, Tan, Exp, LogN

Pm8.00.06:

- Pm.GetSystemInfo new method for detecting the resolution of the screen. It is functional also for Web panels.

- Pm.CpuUsage new property for detecting the load of the CPU.

- Pm.GetActiveWorkspace new method for detecting the active workspace (of the PmaWorkspace object). It can be used for example when creating multi display applications.

- Pm.PrintHtmlPage method: Fixed bug: the printing did not work in Windows OS 7.
