Hello,

I would like to implement an OLE automation in Java for Mathcad (version 11). The data send over "SetComplex" works without problems, the data read out with "GetComplex" I do not get implemented. In addition I have realized with the JACOB Bibiothek the interface and write the following code:

com.jacob.com import *.;

com.jacob.activeX import *.;

Dispatch public class Test

{

public static void main (String [] args)

{

ActiveXComponent xl = new ActiveXComponent ("C: DispatchTest.mcd");

/ / Path of the test program, where the addition is performed by in0 and in1

Object xlo = xl.getObject ();

Dispatch.call (xlo, "SetComplex", "in0", 10, 5);

Dispatch.call (xlo, "SetComplex", "in1", 7, 2);

Dispatch.call (xlo, "Recalculate");

/ / In the Mathcad document now in0 + in1 = out0

Real Estate Part = 0;

Variant ImagPart = 0;

Dispatch.call (xlo, "GetComplex", "out0" real part, ImagPart);

}

}

The error description I get a type mismatch, or a null pointer displayed when the command "GetComplex". Also, the command "Recalculate" can not be executed. If an implementation in Java at all possible? Is there a way to otherwise implement this in C + +?
