Hello,
I have recently connected two weighing scales to my PC and used a VBA tutorial and the XMComm to create Excel user-form that collects the weight data from a scale and places it in a cell. I have managed to connect each scale, and I can retrieve the weight from each one from a separate command button. What I would like to do is combine both scales into one command button. I've tried to do this by putting ActiveCell.Offset(0,1).Select between the two Userforms in the command button. However, when I use this command button, the Active Cell shifts right immediately and only one of the two weight values is placed.
Here is the user-form code:
Private Sub XMCommCRC1_OnComm()
Static sInput As String
Dim sTerminator As String
Dim Buffer As Variant
' Branch according to the CommEvent property
Select Case XMCommCRC1.CommEvent
Case XMCOMM_EV_RECEIVE
Buffer = XMCommCRC1.InputData ' Use Input property for MSComm
sInput = sInput & Buffer
If Worksheets("Settings").Range("Terminator") = "CR/LF" Then
sTerminator = vbCrLf
Else
sTerminaotr = vbCr
End If
If Right$(sInput, Len(sTerminator)) = sTerminator Then
XMCommCRC1.PortOpen = False
sInput = Left$(sInput, Len(sInput) - Len(sTerminator))
Select Case Left$(sInput, 2)
Case "ST", "S "
ActiveCell.Value = CDbl(Mid$(sInput, 7, 8))
ActiveCell.Activate
Case "US", "SD"
MsgBox "The balance is unstable."
Case "OL", "SI"
MsgBox "The balance is showing an eror value."
End Select
sInput = ""
End If
End Select
End Sub
Public Sub RequestBalanceData()
With Worksheets("Settings")
' Configure and open the COM port
If Not XMCommCRC1.PortOpen Then
XMCommCRC1.RThreshold = 1
XMCommCRC1.RTSEnable = True
XMCommCRC1.CommPort = .Range("COM_Port")
XMCommCRC1.Settings = .Range("Baud_Rate") & "," & _
.Range("Parity") & "," & _
.Range("Data_Bits") & "," & _
.Range("Stop_Bits")
XMCommCRC1.PortOpen = True
End If
' Send balance's "SI" (Send Immediate) command
' to request weighing data immediately
If .Range("Terminator") = "CR/LF" Then
XMCommCRC1.Output = "R" & vbCrLf
Else
XMCommCRC1.Output = "R" & vbCr
End If
End With
End Sub
I am using Excel 2007.

If anybody could help me with this issue I'd greatly appreciate it.
