Hi, I am keen to find out why I can't seem to be able to delete all the drawings upon study closure (all at once). The function that triggers the deletion: int i = 0;
s_UseTool j; while (sc.GetUserDrawnChartDrawing(sc.ChartNumber, DRAWING_UNKNOWN, j, i)) { sc.DeleteUserDrawnACSDrawing(sc.ChartNumber, j.LineNumber); i++; } I run the above when the below happens: if (sc.LastCallToFunction == true)
Every time I do that, there are several drawings still left on the chart. What am I missing? Is this a bug? Before you ask, I need to be able to copy these drawings on other charts so I can only use user drawings. Thoughts? |

Yes, it is a bug in your code.while (sc.GetUserDrawnChartDrawing(sc.ChartNumber, DRAWING_UNKNOWN, j, i)) { sc.DeleteUserDrawnACSDrawing(sc.ChartNumber, j.LineNumber); i++; } You are deleting an item from the index, but still incrementing, therefore every other drawing is skipped over. The increment is not needed if the call to delete is successful. |

Thank you so much. You are right. I should have realised that.
