Object Functions

InstallShield 2018 » InstallScript Language Reference

The object functions are available to assist you with initializing objects, as well as obtaining and setting status information for objects.

Object Functions
Function	Description
CoCreateObject	Initializes a COM object and returns a reference that can be assigned to a variable of type OBJECT by using the set keyword.
CoCreateObjectDotNet	The CoCreateObjectDotNet function has been deprecated. Calling this function is the same as calling the DotNetCoCreateObject function with a null string ("") for the szAppDomain parameter. For more information, see DotNetCoCreateObject.
CoGetObject	Returns a reference to the specified COM object (as Visual Basic's GetObject function does); that reference can be assigned to a variable of type OBJECT by using the set keyword.
DotNetCoCreateObject	Calls functions in .NET assemblies without the assembly being registered for COM interoperability. This function, unlike the CoCreateObjectDotNet function, lets you specify the .NET application domain in which the .NET assemblies should be loaded and run.
DotNetUnloadAppDomain	Unloads the specified .NET application domain and releases any assemblies that are currently loaded into the specified application domain.
GetObject	Initializes an object and returns a reference that can be assigned to a variable of type OBJECT by using the set keyword.
GetObjectByIndex	Finds the installation's or object's subobject that is specified by nIndex and returns a reference that can be assigned to a variable of type OBJECT by using the set keyword.
GetObjectCount	Returns the number of subobjects contained by the object or installation.
GetStatus	Retrieves the current status of the object; that is, the current value of Status.Number.
IsObject	Checks whether a variable of type OBJECT has been assigned a reference to a valid object, using the CreateObject or GetObject functions.
SetStatus	Called in an object script to set the object's Status.Number and Status.Description properties.
SetStatusEx	Called in an object script to set the object's status properties.
