I've written studies that send results to a text file. These studies work fine with SC 912 using Whatcom compiler. With SC 996 using MinGW/G++ they no longer work. A basic sample with comments is below: #include "sierrachart.h" #include <iostream> //Appears to have been already included with MinGW & generates errors #include <fstream> //Appears to have been already included with MinGW & generates errors using namespace std; SCDLLName("KAI TEST") SCSFExport scsf_KAI_TEST(SCStudyGraphRef sc) { SCString Buffer; ofstream DataFile; //If I remove the iostream/fstream includes, this fails as not defined if (sc.SetDefaults) { sc.GraphName = "KAI Test Study"; sc.StudyDescription = "KAI Test Study"; sc.GraphRegion = 0; sc.AutoLoop = 1; sc.FreeDLL = 0; return; } DataFile.open ("C:\\KAI_TEST.TXT", ios::out | ios::app); Buffer.Format("%s,%f\n",sc.Symbol.GetChars(), sc.Close[sc.Index]); DataFile << Buffer.GetChars(); DataFile.close(); } } |

I do see an issue the compilation. Also a quick look at the code shows that there is an extra "}" at the end. The following code does compile and output to the file. #include <fstream> #include "sierrachart.h" SCDLLName("KAI TEST") SCSFExport scsf_KAI_TEST(SCStudyGraphRef sc) { if (sc.SetDefaults) { sc.GraphName = "KAI Test Study"; sc.StudyDescription = "KAI Test Study"; sc.GraphRegion = 0; sc.AutoLoop = 1; sc.FreeDLL = 0; return; } SCString Buffer; std::ofstream DataFile("D:\\KAI_TEST.TXT", std::ofstream::out | std::ofstream::app); Buffer.Format("%s,%f\n",sc.Symbol.GetChars(), sc.Close[sc.Index]); DataFile << Buffer.GetChars(); DataFile.close(); } Also please look at the provided Write Bar Data To File study source code found inside of Studies6.cpp scsf_WriteBarDataToFile in the ACS_Source folder within your Sierra Chart installation folder.
