Promotic

Object PmaDll (Dll)

Description:
See: PmaDll - Deatiled object description

The object serves for accessing functions in DLL libraries quite independently on the PROMOTIC system.
By this object it's possible, for example, to make use of IO cards drivers that are supplied by the producers of Microsoft Windows family operation systems exactly in the form of shared dynamically linked libraries (further only DLL libraries).
The PROMOTIC system can be effectively extended by its own DLL libraries. For creation of the DLL libraries it is necessary to use a tool that allows the creation of these libraries - for example Microsoft Visual C++.

No other Pma objects can be created in this object.
This object can be created in objects: PmaRoot, PmaFolder, PmaPrototype. Multiple objects of this type can be created in such objects.
The usage of the PmaDll object requires purchase of the "PmDllActiveX" licence. When developing the application in the freeware mode PmFree, or with development environment and while testing it in runtime, this component is always functional.
This object inherits properties, methods and events of the PmaObject object.
Properties and methods of this object:
CallDllAllows calling functions in DLL library
FceReference to the object accessing functions from the DLL libraries
Properties and methods inherited from the PmaObject object:
AddEventRegisters a function into selected event
GetInfoReturns the Info object with the specified name
GetOwnedByIndexReturns the subobject defined by its index
GetOwnedByNameReturns reference to the subobject defined by its name
GetOwnedByTypeArray of references to the subobjects
GetOwnedNumReturns number of subobjects in the object
GetParReading the value of the Pma object parameter (or its parents)

NameObject name (without the path)
ParentReturns reference to the parent Pma object
PmReturns reference to the Pma object or to its implementation subobject
RemoveEventUn-registers the function in the specified event
RootReturns reference to the root application object PmaRoot
Events inherited from the PmaObject object:
onStartIs triggered for each object in the runtime only once at the beginning
onStopIs triggered for each Pma object in the runtime mode only once at the stop of the application
