SWT Java Inline ActiveX control

This is used in SWT/JFACE development application The ORG.ECLIPSE.SWT.OLE.WIN32 package that SWT comes with can support inline OLE and ActiveX.
The specific usage is as follows:
Create a oleframe as an OLE (or ActiveX) framework
Oleframe oleframe = new Oleframe (this, SWT. NONE);
Create an ActiveX container where the ClassID is an ActiveX ClassID that can be found in the registry
Olecontrolsite OLEControl = new Olecontrolsite (Oleframe, SWT. NONE, "ClassID");
The Oleautomation class is used to execute methods in ActiveX
Oleautomation oleautomation = new oleautomation (OLEControl);
To display ActiveX in application
Olecontrol.doverb (OLE. Oleiverb_show);

To invoke the specific procedure of a method in Acitvex:
1. Method calls without parameters
Get method name Id,method name for ActiveX
int[] Regspid = oleautomation.getidsofnames (new string[] {"MethodName"});
int dispidmember = regspid[0];
Method invocation
Oleautomation.invoke (Dispidmember);

2. Method calls with parameters
Get method name Id,method name for ActiveX
int[] Regspid = oleautomation.getidsofnames (new string[] {"MethodName"});
int dispidmember = regspid[0];
Sets the specific parameters of the method. The length of the variant array is the number of MethodName method parameters
Suppose there are four parameters
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);
Method invocation
Oleautomation.invoke (Dispidmember, Rgvarg);

Calling the OLE Exemple:java program to embed a Word application
