Methods

	Name	Description
	CreateObjRef	Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
	Dispose()	Releases all resources used by the Component. (Inherited from Component.)
	Dispose(Boolean)	Releases the unmanaged resources used by a PrintForm component and optionally releases the managed resources. (Overrides Component.Dispose(Boolean).)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Releases unmanaged resources and performs other cleanup operations before the Component is reclaimed by garbage collection. (Inherited from Component.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetLifetimeService	Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	GetService	Returns an object that represents a service provided by the Component or by its Container. (Inherited from Component.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	InitializeLifetimeService	Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object.)
	MemberwiseClone(Boolean)	Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)
	OnBeginPrint	Raises the BeginPrint event.
	OnEndPrint	Raises the EndPrint event.
	OnQueryPageSettings	Raises the QueryPageSettings event.
	Print()	Sends an image of a Windows Form to the destination specified by the PrintAction property.
	Print(Form, PrintForm.PrintOption)	Sends an image of a Windows Form to the destination specified by the PrintAction property, specifying the form and printing options
	ToString	Returns a String containing the name of the Component, if any. This method should not be overridden. (Inherited from Component.)

Events

	Name	Description
	BeginPrint	Occurs when the Print method is called, before the first page of the document prints.

Remarks

The PrintForm component enables you to print an image of a form to a printer, to a print preview window, or to a file at run time. Its behavior replaces that of the PrintForm method in earlier versions of Visual Basic.

Examples

The following example shows a common use of the PrintForm component.

Dim pf As New PrintForm
pf.Form = Me
pf.PrintAction = PrintToPrinter
pf.Print()

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
