摘要：數(shù)組的長度為方法參數(shù)的個數(shù)假設(shè)有四個參數(shù)方法調(diào)用調(diào)用程序內(nèi)嵌應(yīng)用程序調(diào)用簡單總結(jié)

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

//創(chuàng)建一個OleFrame做為OLE（或ActiveX）的框架
OleFrame oleFrame = new OleFrame(this, SWT.NONE);
//創(chuàng)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(zhí)行ActiveX中的方法
OleAutomation oleAutomation = new OleAutomation(oleControl);
//將ActiveX顯示在application中
oleControl.doVerb(OLE.OLEIVERB_SHOW);

調(diào)用AcitveX中方法的具體過程：
1、不帶參數(shù)的方法調(diào)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(diào)用
oleAutomation.invoke(dispIdMember);

2、帶參數(shù)的方法調(diào)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(shè)置方法的具體參數(shù)。Variant數(shù)組的長度為Method Name方法參數(shù)的個數(shù)
//假設(shè)有四個參數(shù)
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(diào)用
oleAutomation.invoke(dispIdMember, rgvarg);

調(diào)用OLE Exemple：Java程序內(nèi)嵌Word應(yīng)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(diào)用ActiveX簡單總結(jié)

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
