Hi,

I am using Mathcad 13 - VB 6.0 OLE automation for calculations.

Everything was working fine till now. We are planning an upgrade to MathCAD 15.

When I tested the same VB application on MathCAD 15 version am receiving the following error. See the attached screenshot.

System Config: Windows server 2008 standard 64 bit, VB 6.0, Microsoft Office 2010.

Please let me know how can I resolve this issue.

Thanks,

Ram

Private Sub cmdCalc_Click()
 Dim Var1 As New Mathcad.NumericValue
 Dim MathcadApplication As Mathcad.IMathcadApplication2
 Set MathcadApplication = New Mathcad.Application
 MathcadApplication.Visible = False
 MathcadApplication.Worksheets.Open "d:\TestMathcad15.xmcd"
 Var1.Real = CInt(txtval.Text)
 MathcadApplication.ActiveWorksheet.SetValue "A", Var1.Real
 MathcadApplication.ActiveWorksheet.Recalculate
 Var1 = MathcadApplication.ActiveWorksheet.GetValue("B")
 txtOut.Text = Var1.AsString
 Set Var1 = Nothing
 MathcadApplication.ActiveWorksheet.Close mcDiscardChanges
 MathcadApplication.Quit
End Sub

Yes. It gave perfect results with MC13. I have tested it on the server.

But, When tested the same application on MC15. It is giving the error mentioned in the earlier message.

What do u think may be causing it?

I don't know. Do you really have an object called "~", with a method called "~"?
