摘要：數組的長度為方法參數的個數假設有四個參數方法調用調用程序內嵌應用程序調用簡單總結

這里用的是SWT/JFace開發application中SWT自帶的org.eclipse.swt.ole.win32 包可以支持內嵌OLE和ActiveX。
具體用法如下：

//創建一個OleFrame做為OLE（或ActiveX）的框架
OleFrame oleFrame = new OleFrame(this, SWT.NONE);
//創建ActiveX的容器，其中的classID是ActiveX的classid,在注冊表中可以找到
OleControlSite oleControl = new OleControlSite(oleFrame, SWT.NONE, “classID”);
//OleAutomation類用來執行ActiveX中的方法
OleAutomation oleAutomation = new OleAutomation(oleControl);
//將ActiveX顯示在application中
oleControl.doVerb(OLE.OLEIVERB_SHOW);

調用AcitveX中方法的具體過程：
1、不帶參數的方法調用

//獲取Method Name的ID，Method Name為ActiveX中具體的方法名
int[] regspid = oleAutomation.getIDsOfNames(new String[] { "Method Name" });
int dispIdMember = regspid[0];
//方法調用
oleAutomation.invoke(dispIdMember);

2、帶參數的方法調用

//獲取Method Name的ID，Method Name為ActiveX中具體的方法名
int[] regspid = oleAutomation.getIDsOfNames(new String[] { "Method Name" });
int dispIdMember = regspid[0];
//設置方法的具體參數。Variant數組的長度為Method Name方法參數的個數
//假設有四個參數
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);
//方法調用
oleAutomation.invoke(dispIdMember, rgvarg);

調用OLE Exemple：Java程序內嵌Word應用程序

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調用ActiveX簡單總結

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
