本文介绍如何在Eclipse环境中通过注册并集成NTKO控件来编辑和保存Word文档，提供了从注册控件到实现基本功能的详细步骤及示例代码。

最近接到一个任务，需要在eclipse中集成NTKO控件，用于编辑保存word文档，本人只会java编程，对于ocx的使用没有概念。从网上查找了一些示例代码，有的用于发送短信，但是没有内嵌NTKO的代码，自己写一个吧。

1 首先需要注册NTKO，这个信息需要写入到window的注册表中

注册NTKO：
regsvr32 D:\work\NTKO\OfficeControl.ocx
注销NTKO：
regsvr32 /u D:\work\NTKO\OfficeControl.ocx

2 swt中相关的四个类

// 用于存放Ole控件的顶层容器
org.eclipse.swt.ole.win32.OleFrame

// 用于管理内嵌的Ole控件
org.eclipse.swt.ole.win32.OleClientSite

// 用于操作内嵌的Ole控件
org.eclipse.swt.ole.win32.OleAutomation

// 值传输对象，可以传输int、string、boolean、子对象等
org.eclipse.swt.ole.win32.Variant

3 示例代码

package com.weifly.ole;

import org.eclipse.jface.dialogs.MessageDialog;
import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
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.OleAutomation;
import org.eclipse.swt.ole.win32.OleClientSite;
import org.eclipse.swt.ole.win32.OleFrame;
import org.eclipse.swt.ole.win32.Variant;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.ToolBar;
import org.eclipse.swt.widgets.ToolItem;

public class NTKOTest {
	
	private Display display = Display.getDefault();
	private Shell shell = new Shell(display);
	private OleAutomation oa;

	public NTKOTest() {
		shell.setLayout(new GridLayout(1, false));
		
		ToolBar toolBar = new ToolBar(shell, SWT.FLAT | SWT.WRAP | SWT.RIGHT);
		toolBar.setLayoutData(new GridData(SWT.LEFT, SWT.CENTER, true, false));
		
		ToolItem openFileItem = new ToolItem(toolBar, SWT.PUSH);
		openFileItem.setText("打开文件");
		openFileItem.addSelectionListener(new SelectionAdapter(){
			public void widgetSelected(SelectionEvent e) {
				openFileHandler();
			}
		});
		
		final ToolItem showToolbarItem = new ToolItem(toolBar, SWT.PUSH);
		showToolbarItem.setText("显示工具栏");
		showToolbarItem.addSelectionListener(new SelectionAdapter(){
			public void widgetSelected(SelectionEvent e) {
				showToolbarHandler(showToolbarItem);
			}
		});
		
		ToolItem getTextItem = new ToolItem(toolBar, SWT.PUSH);
		getTextItem.setText("文本内容");
		getTextItem.addSelectionListener(new SelectionAdapter(){
			public void widgetSelected(SelectionEvent e) {
				getTextHandler();
			}
		});
		
		createOle();
		
		shell.setSize(500, 400);
		shell.open();

		while (!shell.isDisposed()) {
			if (!display.readAndDispatch()) {
				display.sleep();
			}
		}

		display.dispose();
	}
	
	private void openFileHandler(){
		System.out.println("打开文件");
		Variant[] va = new Variant[3];
		va[0] = new Variant("D:\\test.doc");
		va[1] = new Variant(false);
		va[2] = new Variant("Word.Document");
		execMethod(oa, "OpenLocalFile", va);
	}
	
	private void showToolbarHandler(ToolItem item){
		boolean isShow = getProperty(oa, "ToolBars").getBoolean();
		if(isShow){
			item.setText("显示工具栏");
			setProperty(oa,"ToolBars","false");
		}else{
			item.setText("隐藏工具栏");
			setProperty(oa,"ToolBars","true");
		}
	}
	
	private void getTextHandler(){
		System.out.println("获得文本内容");
		String text = null;
		Variant obj = getProperty(oa, "ActiveDocument");
		if(obj!=null){
			if(obj.getType()==OLE.VT_DISPATCH){
				OleAutomation auto = obj.getAutomation();
				OleAutomation rang = execMethod(auto, "Range", null).getAutomation();
				Variant textVar = (Variant)getProperty(rang, "Text");
				text = textVar.getString();
			}
		}
		MessageDialog.openInformation(shell, "word文档内容", text);
	}
	
	private void createOle(){
		OleFrame frame = new OleFrame(shell, SWT.NONE);
		frame.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
		OleClientSite client = new OleClientSite(frame,SWT.NONE,"NTKO.OfficeControl");  
		
		oa = new OleAutomation(client);
		
		setProperty(oa,"ToolBars","false");
		
		client.doVerb(OLE.OLEIVERB_SHOW);
	}
	
	private void setProperty(OleAutomation oa, String key, String value){
		int[] ia = oa.getIDsOfNames(new String[]{key});
		if(ia!=null && ia.length>0){
			oa.setProperty(ia[0], new Variant(value));
		}
	}
	
	private Variant getProperty(OleAutomation oa, String key){
		int[] ia = oa.getIDsOfNames(new String[]{key});
		if(ia!=null && ia.length>0){
			return oa.getProperty(ia[0]);
		}else{
			return null;
		}
	}
	
	private Variant execMethod(OleAutomation oa, String method, Variant[] params){
		int[] ia = oa.getIDsOfNames(new String[]{method});
		if(ia!=null && ia.length>0){
			return oa.invoke(ia[0], params);
		}
		return null;
	}

	public static void main(String[] args) {
		new NTKOTest();
	}
}

运行效果如图：
