The specific usage is as follows:
//Create an OleFrame as an OLE (or ActiveX) frame
OleFrame oleFrame = new OleFrame(this, SWT.NONE);
//Create an ActiveX container, where the classID is the ActiveX classid, in the registry OleControlSite can be found
oleControl = new OleControlSite(oleFrame, SWT.NONE, "classID");
//The OleAutomation class is used to execute the method in ActiveX
OleAutomation oleAutomation = new OleAutomation(oleControl);
//Display ActiveX in the application
oleControl.doVerb (OLE.OLEIVERB_SHOW);
The specific process of calling the method in AcitveX:
1. Method call without parameters
//Get the ID of Method Name, Method Name is the specific method name in ActiveX
int[] regspid = oleAutomation.getIDsOfNames(new String [] { "MethodName" });
int dispIdMember = regspid[0];
//Method call
oleAutomation.invoke(dispIdMember);
2. Method call with parameters
//Get ID of Method Name, Method Name is the specific method name in ActiveX
int[] regspid = oleAutomation.getIDsOfNames(new String[] { " MethodName" });
int dispIdMember = regspid[0];
//Set the specific parameters of the method. The length of the Variant array is the number of MethodName method parameters
//Assuming 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 call
oleAutomation.invoke(dispIdMember, rgvarg);
