In many
Pma objects or
Pmg objects property configurators in the
Pm.EvalMacro method (but also in other methods) can be used the macro expression.
The macro expression for example allows to enter a text expression in the configurator, that is "evaluated" after starting the application. For example this macro expression can be used for:
- create a complex evaluation of multiple macros, etc.
The macro expression is
always evaluated just once, at application launch, when opening a panel or when calling a method (based on logic of placing) respectively. Therefore it is not possible to assume the macro as a
data binding!
For all configurators or methods with possible macro expression entry, this possibility is allways explicitly stated in the description (see the "PmgString > Text" configurator). There is also the information about the the macro expression evaluation sequence - in most cases:
- The macro expression
in the configurator of the Pma object is evaluated after starting the application.
- The macro expression
in the configurator of the Pmg object is evaluated while the panel is opening.
- The macro expression in the method parameter is evaluated when the method is called.
List of macro expressions:
$.text: Represents the string read from a text file.
$.par: Reference to
Pma object or
Pmg object parameter
$.cfgfile: Represents the value stored in the configuration file.
$.join: Represents a string value composed of all parameters of current expression.
$.path: Represents the full path to the folder or file.
$const: (obsolete) Represents the string quoted directly from current macro expression.
$vb: (obsolete) Represents the result of the specified
VBScript expression evaluation.
