I have an indicator that works just fine on ver 9.1 but I get an error when applied to 9.5 or higher. Placed on a 15 second chart to expedite, once the active bar closes I get a 'Vector is empty or invalid index' error. I have the code below. Any help would be appreciated.

 

Code

using elsystem ; using elsystem.drawingobjects ; using elsystem.drawing ; inputs: BackBars(10), PtOffsetPoint(0.5), UniqueID("GGG"); Vars: ii(0), ptoffset(0), TextLabel BarCounterTxt( NULL ), TextLabel DeleteText(NULL), BNPoint PosBN( NULL ); Arrays: TXID[100](0); method void CreateBNLabel(int barcnt) begin { create position for the text label by bar number using the BNPoint class } PosBN = BNPoint.Create( CurrentBar - barcnt, Low[barcnt]-PtOffsetPoint) ; { create the text label } BarCounterTxt = TextLabel.Create( PosBN, Numtostr(barcnt+1,0) ) ; BarCounterTxt.Font = Font.Create( "Arial", 8 ) ; BarCounterTxt.HStyle = HorizontalStyle.center ; BarCounterTxt.VStyle = VerticalStyle.top; BarCounterTxt.Color = Color.Red ; BarCounterTxt.Tag = UniqueID astype string ; BarCounterTxt.Persist = true ; end ; method void ShowText() begin DrawingObjects.Add( BarCounterTxt ) ; end; //Deleting the Old Texts method void deleteAllText() Var: int textList, int textCnt,int jj ; begin textList = ObjectCategory.TextLabel; textCnt = DrawingObjects.Items[textList].Count; if (LastBarOnChart) then begin for jj = 0 to TextCnt - 1 begin DeleteText = DrawingObjects.Items[textList][jj] astype TextLabel; if (DeleteText <> NULL) and DeleteText.Tag astype string = UniqueID then DrawingObjects.Delete(DeleteText); end; end; end; if (LastBarOnChart) and (BarStatus(1)=2) then begin deleteAllText(); for ii = 0 to BackBars -1 begin CreateBNLabel(ii); ShowText(); end; end;

Pitrader,

this might be caused by your method that deletes the text, as you loop through elements of the drawing collection and delete elements from it during the loop. This can lead to a situation where you try to access an index that is not longer present in the collection, which would trigger the error.
