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 "PmDLL" licence. With the freeware version PmFree, or when developing the application (with development environment for testing purposes), this component is always functional.
This object inherits properties, methods and events of the PmaObject object.
Properties and methods of this object:
CallDll Allows calling functions in DLL library
Fce Reference to the object accessing functions from the DLL libraries
Properties and methods inherited from PmaObject:
AddEvent Registers a function into selected event
GetInfo Returns the Info object with the specified name
GetOwnedByIndex Returns the subobject defined by its index
GetOwnedByName Returns reference to the subobject defined by its name
GetOwnedByType Array of references to the subobjects
GetOwnedNum Returns number of subobjects in the object
GetPar Reading the value of the Pma object parameter (or its parents)
GetPathName Object name with the path to this object
GetPermission Returns permission of corresponding operation from object
Methods Access to designer's methods of this object
Name Object name (without the path)
Parent Returns reference to the parent object in the tree of Pma objects
Pm Returns reference to the Pma object or to its implementation subobject
RemoveEvent Un-registers the function in the specified event
Root Returns reference to the root application object PmaRoot
Events inherited from PmaObject:
onStart Is triggered for each object in the runtime only once at the beginning
onStop Is triggered for each Pma object in the runtime mode only once at the stop of the application
Configuration tabs:
Object General information about the object
Events Definition of object events algorithms
Dll Configuration of the PmaDll object
