java application中内嵌ActiveX控件

我这里用的是SWT/JFace开发application，SWT自带的org.eclipse.swt.ole.win32 包可以支

持内嵌OLE和ActiveX。

具体用法如下：

//创建一个OleFrame做为OLE（或ActiveX）的框架

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

//创建ActiveX的容器，其中的classID是ActiveX的claid,在注册表中可以找到

OleControlSite oleControl = new OleControlSite(oleFrame, SWT.NONE, “classID”);

//OleAutomation类用来执行ActiveX中的方法

OleAutomation oleAutomation = new OleAutomation(oleControl);

//将ActiveX显示在application中

oleControl.doVerb(OLE.OLEIVERB_SHOW);

调用AcitveX中方法的具体过程：

1、不带参数的方法调用

//获取Method Name的ID，Method Name为ActiveX中具体的方法名

int[] regspid = oleAutomation.getIDsOfNames(new String[] { "Method Name" });

int dispIdMember = regspid[0];

//方法调用

oleAutomation.invoke(dispIdMember);

2、带参数的方法调用

//获取Method Name的ID，Method Name为ActiveX中具体的方法名

int[] regspid = oleAutomation.getIDsOfNames(new String[] { "Method Name" });

int dispIdMember = regspid[0];

//设置方法的具体参数。Variant数组的长度为Method Name方法参数的个数

//假设有四个参数

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);

//方法调用

oleAutomation.invoke(dispIdMember, rgvarg);

调用OLE Exemple：Java程序内嵌Word应用程序

package geftest.swt;

import java.io.File;

import org.eclipse.swt.SWT;

import org.eclipse.swt.graphics.Point;

import org.eclipse.swt.layout.GridData;

import org.eclipse.swt.layout.GridLayout;

import org.eclipse.swt.ole.win32.OLE;

import org.eclipse.swt.ole.win32.OleClientSite;

import org.eclipse.swt.ole.win32.OleFrame;

import org.eclipse.swt.widgets.Button;

import org.eclipse.swt.widgets.Display;

import org.eclipse.swt.widgets.Shell;

import org.eclipse.swt.widgets.Composite;

public class ActiveXTest

{

private Shell sShell = null;

private Button button = null;

private OleClientSite clientSite;

public static void main(String[] args)

{

Display display = Display.getDefault();

ActiveXTest thisClass = new ActiveXTest();

thisClass.createSShell();

thisClass.sShell.open();

while (!thisClass.sShell.isDisposed())

{

if (!display.readAndDispatch())

display.sleep();

}

display.dispose();

}

/**

* This method initializes sShell

*/

private void createSShell()

{

GridData gridData = new GridData();

gridData.horizontalSpan = 2;

GridLayout gridLayout = new GridLayout();

gridLayout.numColumns = 3;

sShell = new Shell();

sShell.setText("Shell");

sShell.setLayout(gridLayout);

sShell.setSize(new Point(800, 600));

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(800,600);

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

clientSite.setSize(400,400);

clientSite.doVerb(OLE.OLEIVERB_SHOW);

}

}
