Swt java embedded ActiveX control, swtactivex

The org. eclipse. SWT. ole. win32 package in SWT/JFace development application can be used to support embedded OLE and ActiveX.
The usage is as follows:
// Create an OleFrame as an OLE (or ActiveX) Framework
OleFrame oleFrame = new OleFrame (this, SWT. NONE );
// Create an ActiveX container. The classID is the classid of ActiveX, which can be found in the registry.
OleControlSite oleControl = new OleControlSite (oleFrame, SWT. NONE, "classID ");
// OleAutomation class is used to execute methods in ActiveX
OleAutomation oleAutomation = new OleAutomation (oleControl );
// Display ActiveX in application
OleControl. doVerb (OLE. OLEIVERB_SHOW );

The specific process of calling the method in AcitveX:
1. Call methods without Parameters
// Obtain the ID of the Method Name. The 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. Call methods with Parameters
// Obtain the ID of the Method Name. The Method Name is the specific Method Name in ActiveX.
Int [] regspid = oleAutomation. getIDsOfNames (new String [] {"MethodName "});
Int dispIdMember = regspid [0];
// Set the parameters of the method. The length of the Variant array is the number of MethodName method parameters.
// Assume 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 );
