Acdb with ActiveX Controls Upload Images   Link

  Where do I go for help to get my database working on my new PC?  I use my db to communicate with a PLC via an Activex Control Library.   All the ActiveX Controls work fine on Excel But not on Access.  Someone suggested that I might have to manually edit the registry.  This happened when I switched to a newer PC.
Any leads would be greatly appreciated.  Thank you

Hi Titus. I've moved your post to my Access Developer Network. I don't personally offer consulting and troubleshooting services myself, but maybe one of my other expert Access students will be able to help you.

Very strange that the controls will work in Excel but not Access however. Personally I tell people to avoid 3rd party controls like the plague, but as we've seen with Covid, people don't try to avoid the plague that hard either these days. LOL

There is a PortOpen control that opens a handle to the PLC and that works fine but as soon as I run an AreaRead then Access shuts down.

I haven't done any work with PLCs since the 90s. LOL. If the controls work with Excel but not Access, try running down my Troubleshooter. Maybe you've got a corrupt ACCDB file or something like that.

I finally got the db working again. I had to rewrite a few lines.  Can someone tell me the difference in the code below?
Public p As New FP_CONNECT
Public plcDataArrayReturned as variant
Public Function connecttoplc() As Boolean
Dim plcDataArray(1) As Long
Dim strError As String
Dim plcResult As Integer
     plcResult = p.PortOpen(0, 1)
    If plcResult <> 0 Then GoTo ErrorHandler
        plcDataArrayReturned = p.ReadBits(0, "R10", 1, strError)              '  This worked on my old PC

        plcDataArrayReturned = p.ReadBits(0, "R" & CStr(10), 1, strError)  '  Now I have to convert the number 10 into a string

        ' Why wouldn't the compiler take "R10" as a string only?

        If strError <> "" Then GoTo ErrorHandler
        t = plcDataArrayReturned(0)
     If t = False Then GoTo notheattreating
   ' Other Code
    Exit Function
End Function
