Hello,

 

I'm trying to use a library to interface some LVDT gauges from Marposs. It's implemented through COM objects and I have it working in Excel with VBA with this code:

 

Private Sub CommandButton1_Click()Dim oSmaoMain As SMAO.SMaoMainDim clsInfo As SMAO.InfoDim sInfo As String'Initialize the SMAOMain ObjectSet oSmaoMain = New SMAO.SMaoMainoSmaoMain.Initialize'List all the Installed DriversFor i = 1 To oSmaoMain.DriversCount   sInfo = sInfo & "Driver Name : " & oSmaoMain.Driver(i) & " " & oSmaoMain.DriverDesc(i) & vbNewLineNextMsgBox sInfo, vbOKOnly, "Installed Drivers"'List all the Enabled DriversSet clsInfo = oSmaoMain.InfosInfo = ""For i = 1 To clsInfo.DriversCount   sInfo = sInfo & "Driver Name : " & clsInfo.Driver(i) & " " & clsInfo.DriverDesc(i) & vbNewLineNextMsgBox sInfo, vbOKOnly, "Enabled Drivers"Set clsInfo = NothingSet oSmaoMain = NothingEnd Sub

When I port this code to LabVIEW I get answer from the SMAO.SMaoMain, correct initilization and even I can read the main objects properties. The problem comes when I try to access it's child object SMAO.SMaonMain.Info. When I get the reference and I make calls to the methods/properties, I get different results, always 0 drivers enabled.

 

I've attached the LabVIEW code I'm using and some captures of the creatable objects I can see from LabVIEW.

 

Any idea of what could be happening?

 

 

can you please upload this library and vis
