CurrPos Property

Returns or sets the position of the current line within the file.

Syntax

[form!]C1Awk.CurrPos[ = value As Long ]

Remarks

This property is useful when you want to save the position of current line so that you can easily return to it later.

When you get or set the CurrPos property, the file specified by the FileName property should be open. You may open the file by setting the Action property to acScan or acNextLine, or you may use the FindLine property.

After you set the CurrPos property, the file handle will be repositioned. You must then read the line by setting the Action property to acNextLine.

The example below illustrates how you can do this:

Example Title
Copy Code
' GetStringPos ---------------------------------------------
' Look through a file for a line containing a string.
' Return the position where it was found or -1 if not found
' ----------------------------------------------------------
Function GetStringPos(fname$, fstr$) As Long
awk.FileName = fname ' set file name
awk.FindLine = fstr ' look for string
awk.Action = arClose ' close file
If awk = "" Then ' not found
GetStringPos = -1
Debug.Print fstr; " Not found in "; fname
Else ' found
GetStringPos = awk.CurrPos
Debug.Print fstr; "found at "; awk.CurrPos
End If
End Function
' ReadAtPos-------------------------------------------------
' read a line at a specified position in a file
' ----------------------------------------------------------
Sub ReadAtPos(savedpos&)
awk.Action = acNextLine ' force file open
awk.CurrPos = savedpos ' go to position
awk.Action = acNextLine ' read line
Debug.Print awk ' show line
awk.Action = acClose ' close file
End Sub
