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")

As I stated above. Try:

$Result = _Excel_RangeRead($WBook, "Sheet2")

@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 have embeded an Excel file in my autoit Script and want to use it as part of my GUI. I want to be able to select a range of cells and add the cell data to an edit box. Then dump that data to an array. I am using GUICtrlCreateObj to embed the spreadsheet. I cannot find any way to let my program see what cells are active so I can add that data to the edit box. 
       
      #include <WindowsConstants.au3> #include <GUIConstantsEx.au3> #include <excel.au3> $FileName = 'C:\VLog\book1.xlsx' If Not FileExists($FileName) Then MsgBox(0, "ERROR", "File not found") Exit EndIf ;Basic GUI $oExcelDoc = ObjGet($FileName) ; Get an excel Object from an existing filename If IsObj($oExcelDoc) Then $mainGUI = GUICreate("Production Room 2", 1800, 1200, 10, 10, $WS_MINIMIZEBOX + $WS_SYSMENU + $WS_CLIPCHILDREN) $GUI_ActiveX = GUICtrlCreateObj($oExcelDoc, 10, 70, @DesktopWidth - 250, @DesktopHeight - 260) $data = GUICtrlCreateEdit("", @DesktopWidth - 225, 75, 100) $btn = GUICtrlCreateButton( "GO", @DesktopWidth - 100, 75, 75) Else MsgBox(0, "", "failed") EndIf ;------------------ ;Turns off all command bars in excel to prevent user from making changes For $Bar In $oExcelDoc.CommandBars If $Bar.Enabled = True Then $Bar.Enabled = False If $Bar.Visible = True Then $Bar.Visible = False Next $oExcelDoc.Application.DisplayFormulaBar = False $oExcelDoc.Application.CommandBars("Shadow Settings").Visible = False $oExcelDoc.Application.DisplayScrollBars = True $oExcelDoc.Application.DisplayStatusBar = False GUISetState()

      Hi Guys,
      Can anyone point me in the right direction. I'm trying to accomplished conditional formatting with arrows, but the code I have is wrong... 
      .Range("=$A3:$A4000").FormatConditions.Add = (xlCellValue, xlGreater, "=$A:$A") .IconSet(xl3Arrows) ;ActiveWorkbook.iconsets I also tried it like this:
      .Range("=$A3:$A4000").FormatConditions _ .Add(xlCellValue, xlGreater, "=$A:$A") .IconSet(xl3Arrows) ;ActiveWorkbook.iconsets

      Hi Guys,
      How would you use _Excel_FilterSet to filter the excel sheet from largest number to smallest number?
      _Excel_FilterSet($oWorkbook, "Sheet1", "A2:I2", 1, ">20", 1, "<40") ; OR _Excel_FilterSet($oWorkbook, "Sheet1", "A2:I2", 1, ">", 1, "<") Excel Sheet attached. Trying to filter on the last column "I2"

      Hi All,
      Has anyone come across this before?
      Code below:
      $SheetList = _Excel_SheetList($oWorkbook) _FileWriteFromArray("C:\" & $SheetListOutput, $SheetList, 1) Result:
      ResultABC| ResultDEF| ResultGHI| ResultJKL| ResultMNO| It created these "|" vertical bars?

      Hi All,

      I would like to know how you would take a FileLineRead and insert it into an array which then inserts it into Excel?
      One thing to know is the files content is broken up, so I only use half of the content within $FileRead1.
      So its imperative that the $value1, $value2, etc variables be used. 
      Code below:
      $FileRead1 = FileReadLine("C:\temp\sample.txt",1) For $count = 1 To _FileCountLines($FileRead1) Step 1 $string = FileReadLine($FileRead1, $count) $input = StringSplit($string, ",", 1) $value1 = $input[1] $value2 = $input[2] $value3 = $input[3] $value4 = $input[4] _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value1, "A1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value2, "B1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value3, "C1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value4, "D1") Next
