    Last week, some readers told us they were experimenting with win32 ole msdn. OLE is a mechanism that allows users to create and enhance documents that contain elements or “objects” that are called from multiple applications. OLE was first an acronym for Object Linking and then Embedding.

    This module makes it easy for Perl to interact with OLE Automation. OLE Automation provides VisualBasic as well as scripting functionality and offers powerful extensibility combined with the ability to control many Win32 applications from Perl.Win32::OLE


    What is OLE Object Viewer?

    The OLE COM Object Viewer, Oleview.exe, is an application included with Visual C++ that displays the COM elements installed on your computer and the interfaces they support. You can use this object viewer to view theme and style libraries. Specify the local library file type you want to open and click OK.

    This part uses the IDispatch interface exclusively. NewIt is possible to access a nice personalized interface. OLE OCX and events are not currently supported.

    Actually, this may no longer be the case. This segment now includes ALPHA level support for OLE events. This is largely untested and in particular the interface may change in the future.


    Win32::OLE->new(PROGID[, DESTRUCTOR])

    win32 ole msdn

    The new() class workaround starts a new instance of the new OLE Automation large object. It returns a reference to that object and/or undef if creation failed.

    What is Win32 :: OLE?

    PURPOSE. This module provides a consumer interface for Perl OLE automation. OLE Automation brings VisualBasic-like scripting techniques and offers powerfulextensibility and generally the ability to control many Win32 services from Perl scripts. The Win32::OLE course uses the IDispatch interface exclusively.

    Discussion PROGID must be either a program identifier or a class identifier generated by the required application. The optional specificity destructor is a method of type DESTROY. This will either be a reference to CODE or even a string containing the name of the OLE concept. It can be used to gracefully terminate OLE applications when Perl terminates the program.

    What is OLE container?

    Eliminating OLE containers allows you to add insertable devices to forms in your QBE Vision application system. This makes it easy to integrate all the power and flexibility of applications such as Microsoft Excel and Word found in QBE Vision Forms. The inserted thing usually brings its editing tools into the container.

    To create a really nice DCOM object on an unlikely server, you can useGive Plethora link instead of PROGID. The reference table should contain the new name of the sewing machine and a program ID and/or possibly a class ID. For example:

    my new $obj = Win32::OLE->new(['my.machine.com', 'Program.Id']);

    If PROGID is a program identifier, Win32::OLE attempts to locally resolve the harmonization class identifier. If the course ID is not stored locally, remote registration is requested. This will only succeed if the local community process has read access to the remote registry. The safest (and fastest) manipulation is to specify the class id.Id="Win32::OLE->EnumAllObjects([CALLBACK])"> directly.


    This elegant method returns the number of Win32::OLE objects currently in existence. It can call the optional CALLBACK function to create each of these objects:

     $Count equals Win32::OLE->EnumAllObjects(sub            my $Object implies movement;            some of my $Class = Win32::OLE->QueryObjectType($Object);            printf "# object=%s class=%sn", $object, $class;        );

    Strategies EnumAllObjects() is primarily a debugging tool. For example, it should appear in the END block to check if many outer connections have been safely killed.

    id="Win32::OLE--FreeUnusedLibraries"> Win32::OLE->FreeUnusedLibraries()

    The FreeUnusedLibraries() mode method unloads all unused OLE finances. These are libraries, all existing products of which have been destroyed. The offload associated with a library object is really only relevant for long running processes that are expected to create a large number of different objects over time.

    Note that the hurdles implemented in Visual Basic have only one flawed implementation of this feature: they claim not to load, while many people still use their correct code. Unloading a DLL at this stage usually results in access abuse. You can reduce the risk of this problem by calling the SpinMessageLoop() method and pausing it for a few seconds.

    Win32::OLE->GetActiveObject(CLASS[, DESTRUCTOR])

    GetA methodThe ctiveObject() of the class returns an OLE reference to start the instance that most often connects to the specified OLE Automation server. It benefits from undef when the server is not currently active. It will, if the class manages not to die and it can be saved. The optional DESTRUCTOR method removes either the method name or any code reference. Clarifies when the link to this model last disappeared. It is generally considered rude to close applications that customers have not launched themselves.

    Win32::OLE->GetObject(MONIKER[, DESTRUCTOR])

    win32 ole msdn

    Teaching the GetObject() method returns an OLE reference to the exactly specified object. An object is defined by a path followed by an optionally written additional element subcomponent separated by exclamation marks '!' separates. The optional alignment of DESTRUCTOR has the same semantics as regular new() or GetActiveObject() in a destructor.
