Dear Support Please can you offer some guidance on the following? I have and existing drawing: // Snippet.
if(r_LineNumber_Horizontal_Tool != 0) Tool.LineNumber = r_LineNumber_Horizontal_Tool; Tool.DrawingType = DRAWING_HORIZONTAL_LINE_NON_EXTENDED; Tool.BeginIndex = TOOL_INDEX_POINT_1; Tool.EndIndex = TOOL_INDEX_POINT_1 + 10; // initial index location r_LineNumber_Horizontal_Tool = Tool.LineNumber; // Remember line number which has been automatically set. I'd like to reset it using an index value held in TOOL_INDEX_POINT_2. The following code runs on an event. if(r_LineNumber_Horizontal_Tool != 0)
{ s_UseTool Change_Line_EndIndex; sc.GetUserDrawnDrawingByLineNumber(0, r_LineNumber_Horizontal_Tool, Change_Line_EndIndex); Change_Line_EndIndex.EndIndex = TOOL_INDEX_POINT_2; sc.UseTool(Change_Line_EndIndex); // The following confirms all values are correct an in place. msg.Format("TOOL_INDEX_POINT_1 %i, TOOL_INDEX_POINT_2 %i, r_LineNumber_Horizontal_Tool %i ",TOOL_INDEX_POINT_1,TOOL_INDEX_POINT_2,r_LineNumber_Horizontal_Tool); sc.AddMessageToLog(msg,1); } But there is no change in the lines length? Any help appreciated as I'm a little lost. |

From documentation: When using BeginIndex to modify a drawing, whether user drawn or an Advanced Custom Study added drawing, make sure to clear s_UseTool::BeginDateTime by calling the Clear() function on that SCDateTime variable, in case it has a set Date-Time value. Example: UseTool.BeginDateTime.Clear().
Refer to: Using Drawing Tools From an Advanced Custom Study: s_UseTool::BeginIndex The same also applies to EndIndex. Sierra Chart Support - Engineering Level Your definitive source for support.
