Hello Peter,

I have just worked my way through an ActiveX control problem which gave
exactly the same error message. Your problem is probably not related but
for what its worth I found that OC30.OCX had to be avaiable in
WinNTSystem32 and HPVee had to be version 5.01 (5.0 would not work).

I've misplaced my VEE 5.01 CD-ROM and I need to install the runtime version
on another PC. Could somebody please mail me the Runtime version
installation program?

Thanks,

Tom Evans.

That's funny. Error 552 in my help file says: <name> in the referenced
ActiveX object failed. At any rate, that would indicate Recalculate produced
some error. See if Mathcad has an Error or LastError property or
GetLastError method. As far as type mismatching goes, ActiveX only passes
Variants. I don't know if VEE can do a pointer (ByRef) to a variant.

Hello all,

I want to perform calculations in Mathcad ( Mathcad 8.03 prof.) using
activeX automation.
Mathcad offers the methods SetComplex, Recalculate and GetComplex. Using
SetComplex and Recalculate
to transfer values to Mathcad and recalculate the Mathcad worksheet works
witout problems. But the transfer
from Mathcad to HPVEE (5.01) using GetComplex results in the error message:
error number 552 Type mismatch at argument index 2

Any help is appreciated.

Thanks,
