Mathcad 8.0 and LabView 7.1

[Eugen_Graf]

Hello, I use MathCad 8.0 and LabView 7.1

I got Examples how to use MathCad in LabView from NI-Site, but I cannot use it, because used ActiveX objects are not available.
Then I tryed to open Mathcad with another ActiveX object from Selection. It names IAuto and the method open. And with success.
But I cannot find more methods to write or read data to/from Mathcad.
Can anybody help me?

Thanks Waterman, but this example is cannot be execute.
I asked my frends, they sayed my version of mathcad is to old.

If I e.g. open the VI open mathcad, I see the error MathCad Open File VI is not executable. Then I click this subVI and see the ActiveX objects IMathcadApplication and IMathcadWorksheets have no methods. That means this ActiveX objects are not installed on my PC. But mathcad 8.0 is installed. I think too I have older version of mathcad, which not have this ActiveX interface you use.

I found a another variant to use mathcad, this is OLE-object. And now I can work with mathcad embedded in LabView.
I can set and get vars and I have the method recalculate.

Thanks for your answer!

If you want you can open my example.

Hi Eugen,
   I downloaded your example vi(matncad.vi), it is excellent. I just do not know how to transfer an array into mathcad to do some calculation. Thank you.

I can not make this example work. There always a error from "VSMcad" reference.

Can anyone explain it?

Thanks
