How to read & write Ini File to Excel

Hi,

I am learning how to read & write ini file to Excel Worksheet. I have a VBA code from a book as belows:

ReadIniFile
'**************************************************
Private Function ReadIniFile() As Integer

On Error GoTo ReadIniError

Dim strPath As String
Dim intFNum As Integer
Dim strBuf As String
Dim intRow As Integer
Dim intCol As Integer

'Read INI File and write the data to worksheet
strPath = ActiveWorkbook.Path & "\" & MY_INIFILE
intFNum = FreeFile()
Open strPath For Input Access Read Lock Read As #intFNum
Worksheets("GlobalValues").Unprotect (PASS_SHEET)
Do While Not EOF(intFNum)
------------
End sub

I really don't understand the line 'Open strPath For Input Access Read Lock Read As #intFNum'.

Could any one help me to understand or show me any source (books or web site) which can give me explanation.

Thanks a lot.

Hello Nam,

Here is a breakdown of the Open Statement:
________________________________________________________________
Enables input/output (I/O) to a file.

Syntax

Open pathname For mode [Access access] [lock] As [#]filenumber [Len=reclength]

The Open statement syntax has these parts:

Part Description
pathname Required. String expression that specifies a file name¾may include directory or folder, and drive.
mode Required. Keyword specifying the file mode: Append, Binary, Input, Output, or Random. If unspecified, the file is opened for Random access.
access Optional. Keyword specifying the operations permitted on the open file: Read, Write, or Read Write.
lock Optional. Keyword specifying the operations permitted on the open file by other processes: Shared, Lock Read, Lock Write, and Lock Read Write.
filenumber Required. A valid file number in the range 1 to 511, inclusive. Use the FreeFile function to obtain the next available file number.
reclength Optional. Number less than or equal to 32,767 (bytes). For files opened for random access, this value is the record length. For sequential files, this value is the number of characters buffered.
Remarks

You must open a file before any I/O operation can be performed on it. Open allocates a buffer for I/O to the file and determines the mode of access to use with the buffer.
If the file specified by pathname doesn't exist, it is created when a file is opened for Append, Binary, Output, or Random modes.
If the file is already opened by another process and the specified type of access is not allowed, the Open operation fails and an error occurs.

The Len clause is ignored if mode is Binary.

Important In Binary, Input, and Random modes, you can open a file using a different file number without first closing the file. In Append and Output modes, you must close a file before opening it with a different file number.
