Hi guys, I recently reported that sc.GetStudyIDByIndex and sc.GetStudyIDByName were returning zero. In my program they are BUT it looks like the issue is not either of those functions, It looks like the issue I'm having originates at the sc.AddStudyToChart function. Simply put if I manually add studies to my chart everything looks good. I added these studies manually via the studies window: MovingAverage - Exponential S_ID 27 MovingAverage - Simple S_ID 2 I get the correct values from sc.GetStudyIDByName and sc.GetStudyIDByIndex. I get 1 and 2 respectively. However; if I add the studies by using sc.AddStudyToChart, the return values from both functions are always zero. This is all I am doing: n_ACSIL::s_AddStudy addStudy; addStudy.StudyID = 27; addStudy.ShortName = "MovingAverageExponential"; addStudy.ChartNumber = 1; sc.AddStudyToChart(addStudy); int studyInstanceByIndex = sc.GetStudyIDByIndex(addStudy.ChartNumber, addStudy.StudyID); // Returns 0 int studyInstanceByName = sc.GetStudyIDByName(addStudy.ChartNumber, addStudy.ShortName, true); // Returns 0 Thanks for any help you can supply!

The reason for this is very simple. Calling sc.AddStudyToChart is a delayed action and will not be completed until after your study function returns. If you are using automatic looping and there are multiple calls into the study function, it is not until the chart is updated next, that the study will have been added.

OK, that explains a lot. Maybe that could be added to the sc,AddStudyToChart documentation. Thanks, Richard |
