working though the ACSIL examples on SC website Using Drawing Tools From an Advanced Custom Study // Marker example copied and pasted to NPP ... added #include "sierrachart.h" ... added SCDLLName("Marker example") I received a list of errors when i attempted to Remote Build. thanks code starts below ----------------------------------------------------------------------------------------------------------------------------- #include "sierrachart.h" // Name of the custom study. SCDLLName("Marker example") // Marker example s_UseTool Tool; int UniqueLineNumber = 74191;//any random number. Tool.Clear(); // Reset tool structure. Good practice but unnecessary in this case. Tool.ChartNumber = sc.ChartNumber; Tool.DrawingType = DRAWING_MARKER; Tool.LineNumber = UniqueLineNumber +1; BarIndex = max(0, sc.ArraySize - 35); Tool.BeginDateTime = sc.BaseDateTimeIn[BarIndex]; Tool.BeginValue = sc.High[BarIndex]; Tool.Color = RGB(0,200,200); Tool.AddMethod = UTAM_ADD_OR_ADJUST; Tool.MarkerType = MARKER_X; Tool.MarkerSize = 8; Tool.LineWidth = 5; sc.UseTool(Tool); compiler errors start below ----------------------------------------------------------------------------------------------------------------------- -- Starting remote build of Custom Studies Source files: Markerexample.cpp. 64-bit -- 18:21:30 Allow time for the server to compile the files and build the DLL.

i figured out part of my error... i simply copied the code and didn't make a study out of it. I re wrote the study including some of what is required to make it work. code starts below ============================================================================================================================================ #include "sierrachart.h" // Name of the custom study. SCDLLName("Markerexample") SCSFExport scsf_Markerexample(SCStudyInterfaceRef sc) { if (sc.SetDefaults) { sc.GraphName = "Function"; sc.AutoLoop = 1; // Automatic looping is enabled. return; } // Marker example s_UseTool Tool; int UniqueLineNumber = 74191;//any random number. Tool.Clear(); // Reset tool structure. Good practice but unnecessary in this case. Tool.ChartNumber = sc.ChartNumber; Tool.DrawingType = DRAWING_MARKER; Tool.LineNumber = UniqueLineNumber +1; BarIndex = max(0, sc.ArraySize - 35); Tool.BeginDateTime = sc.BaseDateTimeIn[BarIndex]; Tool.BeginValue = sc.High[BarIndex]; Tool.Color = RGB(0,200,200); Tool.AddMethod = UTAM_ADD_OR_ADJUST; Tool.MarkerType = MARKER_X; Tool.MarkerSize = 8; Tool.LineWidth = 5; s_sc.UseTool(Tool); } error starts here ========================================================================================================================================================= -- Starting remote build of Custom Studies Source files: Markerexample.cpp. 64-bit -- 20:29:02 Allow time for the server to compile the files and build the DLL. The remote build did not succeed. Result: Markerexample.cpp: In function 'void scsf_Markerexample(SCStudyInterfaceRef)': Markerexample.cpp:31:1: error: 'BarIndex' was not declared in this scope 31 | BarIndex = max(0, sc.ArraySize - 35); | ^~~~~~~~ Markerexample.cpp:44:5: error: expected unqualified-id before '.' token 44 | s_sc.UseTool(Tool); | ^ -- End of Build -- 20:29:08 still cant make it work but am closer |

i declared BarIndex as int BarIndex (0) so I'm down to Allow time for the server to compile the files and build the DLL. The remote build did not succeed. Result: Markerexample.cpp: In function 'void scsf_Markerexample(SCStudyInterfaceRef)': Markerexample.cpp:49:5: error: expected unqualified-id before '.' token 49 | s_sc.UseTool(Tool); | ^ -- End of Build -- 22:03:31 I don't know what this is or how to fix it. |

Change s_sc.UseTool(Tool); to sc.UseTool(Tool); That is all. s_sc is the type of struct, your function needs to use 'sc', which is a reference passed into the function by SCStudyInterfaceRef sc. SCStudyInterfaceRef is typedef alias for s_sc&, and sc is the variable name. |

thank you... that worked. the example on the site shows that with the s_sc.Usetool(tool) so I just copied it that way. I got a ways to go yet on understanding all the syntax and what all the functions do. Some of the examples ive found are older and I'm guessing theres been some changes made. anyway thanks again
