This article focuses on "how to use java embedded activeX controls". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to use java embedded activeX controls.

Here SWT/JFace is used to develop the org.eclipse.swt.ole.win32 package that comes with SWT in application to support embedded OLE and ActiveX.

The specific usage is as follows:

/ / create a framework with OleFrame as OLE (or ActiveX)

OleFrame oleFrame = new OleFrame (this, SWT.NONE)

/ / create a container for ActiveX, where classID is the classid of ActiveX, which can be found in the registry

OleControlSite oleControl = new OleControlSite (oleFrame, SWT.NONE, "classID")

/ / the OleAutomation class is used to execute methods in ActiveX.

OleAutomation oleAutomation = new OleAutomation (oleControl)

/ / display ActiveX in application

OleControl.doVerb (OLE.OLEIVERB_SHOW)

The specific process of calling a method in AcitveX:

1. Method calls without parameters

/ / get the ID,Method Name of Method Name as the specific method name in ActiveX

Int [] regspid = oleAutomation.getIDsOfNames (new String [] {"MethodName"})

Int dispIdMember = regspid [0]

/ / method call

OleAutomation.invoke (dispIdMember)

2. Method call with parameters

/ / get the ID,Method Name of Method Name as the specific method name in ActiveX

Int [] regspid = oleAutomation.getIDsOfNames (new String [] {"MethodName"})

Int dispIdMember = regspid [0]

/ / set the specific parameters of the method. The length of the Variant array is the number of MethodName method parameters

/ / suppose there are four parameters

Variant [] rgvarg = new Variant [4]

Rgvarg [0] = new Variant (fileID)

Rgvarg [1] = new Variant (itdsURL)

Rgvarg [2] = new Variant (idType)

Rgvarg [3] = new Variant (reportURL)

/ / method call

OleAutomation.invoke (dispIdMember, rgvarg)

Call OLE Exemple:Java program embedded Word application program

{

GridLayout.numColumns = 3

SShell = new Shell ()

SShell.setText ("Shell")

SShell.setLayout (gridLayout)

SShell.setSize (new Point (800600))

OleFrame frame = new OleFrame (sShell, SWT.NONE)

Button = new Button (sShell, SWT.NONE)

Button.setLayoutData (gridData)

Button.setText ("Save")

Button.addSelectionListener (new org.eclipse.swt.events.SelectionAdapter () {

Public void widgetSelected (org.eclipse.swt.events.SelectionEvent e)

{

ClientSite.save (new File ("d:/test.docx"), true)

}

});

Frame.setSize (800600)

ClientSite = new OleClientSite (frame, SWT.NONE, "Word.Document.8")

ClientSite.setSize (400400)

ClientSite.doVerb (OLE.OLEIVERB_SHOW)

}

}

Simple summary of SWT calling ActiveX

Public class SWT_ActivexUtil {

Private OleFrame _ frame

Private OleControlSite _ site

Private OleAutomation _ auto

SWT_ActivexUtil (String activexId, OleControlSite site) {

If (site = = null) {

Shell shell = new Shell ()

_ frame = new OleFrame (shell, SWT.NONE)

_ site = new OleControlSite (_ frame, SWT.NONE, activexId)

_ auto = new OleAutomation (_ site)

} else {

_ site = site

_ auto = new OleAutomation (site)

}

}

Public int getID (String name) {

Try {

Int [] ids = _ auto.getIDsOfNames (new String [] {name})

If (ids.length > = 0)

Return ids [0]

} catch (RuntimeException e) {

E.printStackTrace ()

}

Return-1

}

Public Variant [] createVariants (String [] paras) {

Variant [] vr = new Variant [paras.length]
