Hi, Can you check the sc.SetPersistentSCStringForChartStudy() function. When I use it it crashes SC. Frederik |

You need to check your own code for a problem. That function has no problems. And we cannot reproduce any issue with it either. But we do observe, that the implementation is not as efficient as it should be and we will correct that by not passing copies of the string.

Run the below code and let me know if you can reproduce the problem. SCSFExport scsf_Receiving_SCString(SCStudyInterfaceRef sc)
{ if (sc.SetDefaults) { // Set the configuration and defaults sc.GraphName = "Receiving SCString"; sc.StudyDescription = "Receiving SCString"; sc.AutoLoop = 0; return; } SCString& SomeString = sc.GetPersistentSCString(0); // Do data processing if (sc.UpdateStartIndex == 0 && sc.IsFullRecalculation) { sc.AddMessageToLog(SomeString,1); } } SCSFExport scsf_Sending_SCString(SCStudyInterfaceRef sc) { SCInputRef ChartStudyReference = sc.Input[0]; if (sc.SetDefaults) { // Set the configuration and defaults sc.GraphName = "Sending SCString"; sc.StudyDescription = "Sending SCString"; ChartStudyReference.Name = "Chart Study Reference"; ChartStudyReference.SetChartStudyValues(1, 0); sc.CalculationPrecedence = LOW_PREC_LEVEL; sc.AutoLoop = 0; return; } // Do data processing if (sc.UpdateStartIndex == 0 && sc.IsFullRecalculation) { sc.SetPersistentSCStringForChartStudy(ChartStudyReference.GetChartNumber(),ChartStudyReference.GetStudyID(),0,"This is a test string"); } } |

Would be doubtful we would encounter a problem. We suspect we know what the problem is. Most likely it is just simply a small compatibility issue between the different compilers with passing of class parameters as copies in function calls. This will be resolved in the next release.

I run SC 1987 and this is example code remote build showing a v1977 dll. It will crash and I know you will fix it. Would appreciate an update in this thread which release this is fixed. Thanks. Frederik |
