Hallo,

I'm working on a fresh environment with visual studio 2019 (free edition) and solidworks 2018 (installed on same machine).

I start from the beginning….but is not working and also all the example attached on documentation are non working.

I started a new project > vb.net console application

Added reference to Solidworks.Interop.sldworks and Solidworks.Interop.swconst

And this is my code

Imports SolidWorks.Interop.sldworks
Imports SolidWorks.Interop.swconst

Module Module1
Sub main()

Dim swPart As PartDoc
Dim swModel As ModelDoc2
Dim swModelDocExt As ModelDocExtension
Dim swImportStepData As ImportStepData
Dim status As Boolean
Dim errors As Integer
Dim warnings As Integer
Dim fileName As String
Dim stepFileName As String
Dim swApp As SldWorks = CreateObject("SolidWorks.Application")
'Open the SOLIDWORKS part document to export to a STEP file
fileName = "C:\Program Files\SOLIDWORKS Corp\SOLIDWORKS\Toolbox\data\SteelLib\channel.sldprt"
swPart = swApp.OpenDoc6(fileName, swDocumentTypes_e.swDocPART, swOpenDocOptions_e.swOpenDocOptions_Silent, "", errors, warnings)
swModel = swPart
swModelDocExt = swModel.Extension

'Export the SOLIDWORKS part document to a STEP file
stepFileName = "C:\Users\Luca\Desktop\api\db9 male.STEP"
status = swModelDocExt.SaveAs(stepFileName, 0, swSaveAsOptions_e.swSaveAsOptions_Silent, Nothing, errors, warnings)
swPart = Nothing

swApp.CloseDoc("db9 male.sldprt")

'Get import information
swImportStepData = swApp.GetImportFileData(stepFileName)

'If ImportStepData::MapConfigurationData is not set, then default to
'the environment setting swImportStepConfigData; otherwise, override
'swImportStepConfigData with ImportStepData::MapConfigurationData
swImportStepData.MapConfigurationData = True

'Import the STEP file
swPart = swApp.LoadFile4(stepFileName, "r", swImportStepData, errors)
swModel = swPart
swModelDocExt = swModel.Extension

'Run diagnostics on the STEP file and repair any bad faces
errors = swPart.ImportDiagnosis(True, False, True, 0)

End Sub

End Module

When I try to run I get the following error:

System.Exception

HResult=0x80131500

Message=Cannot create ActiveX component.

Source=Microsoft.VisualBasic

StackTrace:

at Microsoft.VisualBasic.Interaction.CreateObject(String ProgId, String ServerName)

at ConsoleApp1.Module1.main() in C:\Users\Luca\Documents\Visual Studio 2019\Project\ConsoleApp1\ConsoleApp1\Module1.vb:line 19

on line highlighted in bold.

I did not find any fresh code on solidworks example.
