krishpun Posted April 7, 2011 Share Posted April 7, 2011 Please help to identify the column position in a 2D array. Example: I have a 2D array as below. $ar1[0][0]="Name" $ar1[0][1]="Age" $ar1[0][2]="state" $ar1[0][3]="country" $ar1[1][0]="John" $sr="state" I want to know the column position where "state" exist (in the first row of this 2D array)? ie... I am expecting answer of "2" (second column). I am trying with _ArraySearch as below, but still no luck. $dbm1 = _ArraySearch($ar1, $sr) MsgBox(1,"s",$dbm1) --> This returns the row position ie... 0 but I need column position in this first row. regards, Krishna Link to comment Share on other sites More sharing options...
BrewManNH Posted April 7, 2011 Share Posted April 7, 2011 _ArraySearch will let you search by column, but you'd have to know which column to search in, otherwise you'd have to search each column one at a time. You could use _ArraySearch to find which row your item is in, then loop through the elements of that row to find the column number. If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.Give a programmer the correct code and he can do his work for a day.

Moderators Melba23 Posted April 7, 2011 Moderators Share Posted April 7, 2011 krishpun, Or search each column in turn like this: #include <Array.au3> Global $ar1[2][4] $ar1[0][0] = "Name" $ar1[0][1] = "Age" $ar1[0][2] = "state" $ar1[0][3] = "country" $ar1[1][0] = "John" $sr = "state" ; For each column For $i = 1 To UBound($ar1, 1) ; Search for the value $dbm1 = _ArraySearch($ar1, $sr, 0, 0, 0, 0, 1, $i) ; If found If $dbm1 <> -1 Then ; Display column number MsgBox(1, "s", $i) EndIf Next M23 Any of my own code posted anywhere on the forum is available for use by others without any restriction of any kind Open spoiler to see my UDFs: Spoiler ArrayMultiColSort ---- Sort arrays on multiple columnsChooseFileFolder ---- Single and multiple selections from specified path treeview listingDate_Time_Convert -- Easily convert date/time formats, including the language usedExtMsgBox --------- A highly customisable replacement for MsgBoxGUIExtender -------- Extend and retract multiple sections within a GUIGUIFrame ---------- Subdivide GUIs into many adjustable framesGUIListViewEx ------- Insert, delete, move, drag, sort, edit and colour ListView itemsGUITreeViewEx ------ Check/clear parent and child checkboxes in a TreeViewMarquee ----------- Scrolling tickertape GUIsNoFocusLines ------- Remove the dotted focus lines from buttons, sliders, radios and checkboxesNotify ------------- Small notifications on the edge of the displayScrollbars ----------Automatically sized scrollbars with a single commandStringSize ---------- Automatically size controls to fit textToast -------------- Small GUIs which pop out of the notification area Link to comment Share on other sites More sharing options...
krishpun Posted April 7, 2011 Author Share Posted April 7, 2011 Thanks, but it works only for "state". It does not work for other values say, "country" Please let me know what change should I make? #include <Array.au3> Global $ar1[2][4] $ar1[0][0] = "Name" $ar1[0][1] = "Age" $ar1[0][2] = "state" $ar1[0][3] = "country" $ar1[1][0] = "John" $sr = "country" ; For each column For $i = 1 To UBound($ar1, 1) ; Search for the value $dbm1 = _ArraySearch($ar1, $sr, 0, 0, 0, 0, 1, $i) ; If found If $dbm1 <> -1 Then ; Display column number MsgBox(1, "s", $i) EndIf Next Link to comment Share on other sites More sharing options...
Moderators Melba23 Posted April 7, 2011 Moderators Share Posted April 7, 2011 krishpun,My apologies - I used the wrong value for the dimension parameter in UBound which, by chance, worked for the "state" case. Please change the line to read:For $i = 0 To UBound($ar1, 2) - 1and all should be well.

sahsanu Posted April 7, 2011 Share Posted April 7, 2011 (edited) I was taking a look before I see Melba23's reply but... here another "dirty" way Global $ar1[2][4] $ar1[0][0] = "Name" $ar1[0][1] = "Age" $ar1[0][2] = "state" $ar1[0][3] = "country" $ar1[1][0] = "John" $sr = "country" For $i = 0 To UBound($ar1,1)-1 For $f = 0 To UBound($ar1,2)-1 $dbm1=StringInStr($ar1[$i][$f],$sr) If $dbm1 <> 0 Then ; Display column number MsgBox(1, "s", $f) EndIf Next Next Edited April 7, 2011 by sahsanu Link to comment Share on other sites More sharing options...
