Lotus Notes : Not able to access properties file in lotuscript - lotus-notes

Question

Hi friends i want to access the properties file from machine from the specified path. For java Agent i used Properties method and extracted the data from the properties file. but now i want it to be done in lotuscript. I tried using properties method but it didnt work so i thought to read properties with the below code.
'Dim ColFileName As String
'ColFileName="C:\abcd.properties"
Open ColFileName For Input As 1
Do While Not EOF(1)
Line Input #1,txt$
MsgBox "TEXT FILE:"+txt$
In properties file i have a written it as
col=start
where i want to get the property of the col using getProperty method in java same way for lotusscript.
I added the above code but it is not working. Can anyone tell what mistake i have committed.

In Options
%Include "lserr.lss" 'This is just a list of constants.
Add these functions somewhere:
%REM
Function fstreamOpenFile(sPath As String, bTruncate As Boolean, bConfirmExists As Boolean) As NotesStream
<dl>
<dt>sPath</dt><dd>Filepath of the file to be opened/created.</dd>
<dt>bTruncate</dt><dd>Boolean. True if file is for output and any existing file should be replaced rather than appended to.</dd>
<dt>bConfirmExists</dt><dd>Boolean. If True, and the opened file is empty, then an ErrFileNotFound error will be thrown.</dd>
</dl>
%END REM
Function fstreamOpenFile(sPath As String, bTruncate As Boolean, bConfirmExists As Boolean) As NotesStream
Dim session as New NotesSession Dim stream As NotesStream
Set stream = session.Createstream()
If Not stream.Open(sPath) Then Error ErrOpenFailed, {Could not open file at "} + sPath + {"}
If bConfirmExists And stream.Bytes = 0 Then Error ErrFileNotFound, {File at "} + sPath + {" is missing or empty.}
If bTruncate Then Call stream.Truncate()
Set fstreamOpenFile = stream
End Function
Function fsPropertyFileValue(sFilePath As String, sPropertyName As String, sDefaultValue As String) As String
On Error GoTo ErrorQuietly
Dim stream As NotesStream
Dim sLine As String
Dim sLeft As String
Dim iLeftLen As Integer
Set stream = fstreamOpenFile(sFilePath, False, True)
sLeft = sPropertyName + "="
iLeftLen = Len(sLeft)
Do
sLine = stream.Readtext
If Left(sLine, iLeftLen) = sLeft Then
fsPropertyFileValue = Right(sLine, Len(sLine) - iLeftLen)
Exit Function
End If
Loop Until stream.Iseos
ReturnDefault:
fsPropertyFileValue = sDefaultValue
Exit Function
ErrorQuietly:
Print Now, Error$
Resume ReturnDefault
End Function
(Notes: I have not tested/debugged fsPropertyFileValue. The html tags in the comment is because, when editing an agent or script library, the designer client will parse and display the HTML tags.)
Then you can use fsPropertyFileValue("C:\abcd.properties", "col", "start") to get the value of the col property within C:\abcd.properties and, if that fails, use "start".
