Error combining VBA - SuperPro Designer

[evalent]

Hi all,

I encountered this error while running VBA code.

Run-time error '-2147417848 (80010108)': Automation error, the object invoked has disconnected from its client.

The VBA code is connected to Superpro designer. The aims of the VBA are to set the value in the process simulation and get the final mass balance.

Anyone encountered this before?

Thanks in advance.

Sure, the object has been closed but not set to nothing. This gives the same error...

Sub test()    Dim w As Word.Application
    Dim d As Word.Document
    
    Set w = New Word.Application: w.Visible = True
    
    'Create a new document and close it
    Set d = w.Documents.Add: d.Close False
    
    On Error Resume Next
    Debug.Print d.Name '<--- CANNOT GET NAME SINCE OBJECT IS CLOSED
    Debug.Print Err.Number, Err.Description
    
    w.Quit
    
End Sub

Hi jonh,
thanks for your reply.

I did the same but without closing it.

Function dir(input as double) as variant

Dim superProApp As Designer.Application
Dim superProDoc As Designer.Document

Set superProApp = New Designer.Application
Set superProDoc = superProApp.OpenDoc("D:\xxx.spf")

. 'this is where the code is written. it is quite long so i dont paste it here.
.
.

dir  = result


End Function

In the code I wrote, there is no close routine.

Is that what you meant? Sorry if I misunderstood.

Hi jonh,

I solved the problem. I dont know why but the error does not appear anymore when I introduced the close routine.

superProDoc.CloseDoc False
superProApp.CloseApp

Thanks for helping!

Hi everyone, I´m new in this forum
Anyone knows what ByRef means? and how to fix it? I cannot solve this

[marucina]

If superProApp Is Nothing Then MsgBox "First open a SuperPro Designer case file."
Exit Sub
End If

Set ws = Worksheets("Throughput Analysis")

compFlow = ws.range("D10")
increase = ws.range("D11")

Application.Cursor = xlWait
Application.DisplayStatusBar = True
Application.StatusBar = "Please wait while script is running ..."

ws.range("A19") = "Performing Calculations for"
ws.range("A18:A22").Interior.Color = RGB(255, 128, 0)
ws.range("A21") = "Batch Throughput " & throughput & " kg/batch"
SetAndGetIngredientFlow compFlow
ws.range("B16") = compFlow

Dim dCell As range
For Each dCell In range("B17:B40")

compFlow = compFlow + increase
ws.range("A21") = "Batch Throughput " & throughput & " kg/batch"
SetAndGetIngredientFlow compFlow [I have ByRef issues with this compFlow]
dCell = compFlow

ws.range("A21") = Empty
Next dCell

ws.range("A19") = Empty
ws.range("A18:A22").Interior.ColorIndex = xlNone
Application.Cursor = xlDefault
Application.StatusBar = False
End Sub

Here you can find how I declare it

'Global Declarations
Public superProApp As Designer.Application
Public superProDoc As Designer.Document


'Module 1 Declarations
Dim var1 As Variant
Dim var2 As Variant
Dim str1 As String
Dim str2 As String
Dim streamName As String
Dim componentName As String




'Throughput and Economic Indices Functions


'Set And Get Antocyanin Flow
Function SetAndGetIngredientFlow(streamName As String, componentName As String, compFlow As Double) As Double


str1 = CStr(streamName)
str2 = CStr(componentName)
var2 = CDbl(compFlow)


streamName = "Quinaldine"
componentName = "Quinaldine"


superProDoc.SetStreamVarVal str1, VarID.componentMassFlow_VID, var1, str2

'Solve Mass & Energy Balances
superProDoc.DoMEBalances var1
'Economic Calculations
superProDoc.DoEconomicCalculations

superProDoc.GetStreamVarVal str1, VarID.componentMassFlow_VID, var2, str2
SetAndGetIngredientFlow = CDbl(var2)


End Function
