swt java 内嵌ActiveX控件

摘要：数组的长度为方法参数的个数假设有四个参数方法调用调用程序内嵌应用程序调用简单总结

这里用的是SWT/JFace开发application中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classid,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 test.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);
}
}

SWT调用ActiveX简单总结

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];
for(int i=0;i
