Code stopped working 2014 upgrade 2021

[Jef_E]

Hi all,

We are currently going to migrate to 2021, and I am checking some 'custom' work we have running. Sadly I cannot seem to get it to work to the full extent. Previously I did a check to the 2019 version and did not encounter the same problem

I receive following error when editing a parameter  value.

The current value = 30

The new value = 35

I can't seem to figure it out why this is failing.

Kind regards,

[Jef_E]

In addition I did another test; I started a new plugin using the guide, with following code, producing the same error when setting the value.

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

        Dim oDoc As PartDocument = _invApp.ActiveDocument

        Dim oParameter As Parameter = oDoc.ComponentDefinition.Parameters.Item("Nozzle_length_positioning")
        MsgBox(oParameter.Value)
        oParameter.Value = 35
        MsgBox(oParameter.Value)
    End Sub

Kind regards,

Did you try

...Value = (Value / 10)

No I did not, as this is not the problem...

Hi @Jef_E 

I've tried to reproduce the error in both inventor 2020 and 2021 with no luck... which Autodesk.Inventor.Interop.dll are you referencing? Could you attach a simple VS project where this error occurs?

On the line that fails, if you hover over the three highlighted terms below, what does Visual Studio say is their type (e.g. hovering over "Value" shows "Property Parameter.Value As Object")?

oParameters . Item("Nozzle_length_positioning") . Value = value / 10
