Hi all,

Why use _Excel_RangeRead in a loop - that takes forever.

Use the function with default values and it will return an array with all used cells.

The function page says that _Excel_RangeRead returns the data from the specified cell(s). A string for a cell, a zero-based array for a range of cells. Cant you use ubound with the returned array?

untested guess:

$data = _Excel_RangedRead($oWorkbook, Default, "A1")
For $i = 2 to ubound($data) - 1

According to the help file:

"$vRange [optional] Either a range object or an A1 range. If set to Default all used cells will be processed (default = keyword Default)"

If IsArray($data) Then
    If UBound($data, 0) = 2 Then ; 2D-array
        For $i = 0 To UBound($data, 1) - 1
            ; process first column of the returned 2D-array: $data[$i][0]
        Next
    Else
        For $i = 0 To UBound($data, 1) - 1
            ; process first column of the returned 2D-array: $data[$i]
        Next
    EndIf
EndIf

@water & @

computergroove, I have a workbook and it contains data in F2 to F22. Now, I need to read that data. But next time, my program has no idea about what is the upper limit. Now it is F22. But next time it will be F34 or F56 or something like that. Then how can i find it without a loop. And with this code, i only get one cell value. Not an array
$Result = _Excel_RangeRead($WBook, "Sheet2", "F2")

@water, it will give all the data in that sheet. I think that will slow down my program a bit. Am i right ?

Only a bit. But $WBook.ActiveSheet.Usedrange.Columns is faster, no doubt.

      I'm using this for replacing text strings in the VBProject of all excel files in a folder and subfolders.
      I have the same text string in several lines and those lines could have some differences between files: then not feasible for .ReplaceLine method
      I'm not interested in placing all the code in a xla AddIn, because the code is similar but not exactly the same in all the files.
