Hello,
Does any one out there have any experience with The CPS PLUS
serial data acquisition program?
I am trying to read data from a com port and put it into an Excel
spread sheet. I want to use CPS Plus because it is cheaper than the
WINWEDGE program and if i can get it to work i will be sending licensed

versions to several clients.


I am going in to an excel file cps.xls and into tools, then,macros,
then opening modules, and writing this code below into different
modules.


what i want to do is:::
i want to open the cps.xls file but i never want to write data to it,
as soon as i open it i want to open another file using this code:


Global Filename$


Sub AutoName()
' NameCheck Macro


Static StrLenDate, StrLenTime
SysDate$ = Date
SysTime$ = Time
StrLenDate = Len(SysDate$)
StrLenTime = Len(SysTime$)
A$ = "A"
P$ = "P"
Ms$ = "M"
Spaces$ = Chr(32)
Slashs$ = Chr(47)
Colons$ = Chr(58)


' Strip out slashes & spaces from the date
For j = 1 To StrLenDate


StringBit$ = Mid$(SysDate$, j, 1)


If StringBit$ = Spaces$ Then
StringBit$ = "-"
Mid$(SysDate$, j, 1) = StringBit$
End If


If StringBit$ = Slashs$ Then
StringBit$ = "-"
Mid$(SysDate$, j, 1) = StringBit$
End If


Next j


' Add a space to end of date
SysDate$ = SysDate$ + Spaces$


' strip out colon from the time
For k = 1 To StrLenTime
StringBit$ = Mid$(SysTime$, k, 1)
If StringBit$ = Colons$ Then
StringBit$ = " "
Mid$(SysTime$, k, 1) = StringBit$
End If
Next k
'Find the seconds portion of the time and strip it out
StringByte$ = Right(SysTime$, 5)
For M = 1 To 5
StringBit$ = Mid$(StringByte$, M, 1)
If StringBit$ = A$ Then
TimeofDay$ = A$ + Ms$ ' For AM
ElseIf StringBit$ = P$ Then
TimeofDay$ = TimeofDay$ + P$ + Ms$ 'For PM
Else
Mid$(StringByte$, M, 1) = ""
End If
Next M
'replace into time
TimeLen = Len(SysTime$)
SysTime$ = Mid$(SysTime$, 1, TimeLen - 5)
Filename$ = SysDate$ + SysTime$ + TimeofDay$


ActiveWorkbook.SaveAs (Filename$)
'This saves the file with the date and time as the filename


End Sub


Then i want to , write what ever data comes in from the comport to the
first row of this new file.


I got this to work. Now when the next line of data comes in , I need to

check the first 2 characters(this is the PartID#), if these 2
characters are the same as the last line of data's first 2 characters
then i just write this new line of data into the next row of the spread

sheet.But,if these first 2 characters are different than the the data
from the first line, then i need to open yet another file and put this
newdata in to it, that is where the problem starts, I am using
this code to do this:


Sub End_of_Log()
'
If PtID$ < PrevPtID$ Then
ActiveWorkbook.Save
Workbooks.Open "C:\cps\cps.xls" 'cps
' Call auto_open
'activeworkbook.runautomacro xlautoopen
' call Autoname
ThisWorkbook.Close


End If
End Sub


*******
*******
When i do this it just opens up the cps.xls and it does not
get any new data
if i use the Call Auto_open or activeworkbook.runautomacro...,
it gives me the error
"the macro c:\cps.xls'|CPS_GetCOM1Data' cannot be found
if i call autoname i get different errors.
Does Any one know why or what to do??

sorry such a long portrayal of the problem.
any help would be appreciated.
Thank you
