f$GetNumProp (f$LiesNumProp)

Properties that are present as numbers can be read with this function for specified dialog objects. A requirement for this function is that the dialog concerned was opened with f$DialogOpen.

Note: this is an expert function intended for demanding usage scenarios. In normal cases the f$Dialog function should be used.

The dialog element to be read is identified through a name given to the dialog object in the Dialog Editor (see Naming dialog objects)

Note: not every property is available for each dialog element, e.g. a fixed text cannot be enabled.

Please note:

If you try to set an unavailable property for a dialog field, an error message is not produced and the command is ignored.
