Hi Support...I've followed the instructions for 1459. I also clicked the install compiler option and it just redoes the installation I have already done. NOTICE: New Custom Studies DLL Compiler/Solution to Compile Error Issue The following are errors I now get. The prior compiler to 1459 worked without any errors for my custom code. I will need to downgrade for now back to 1455 Can you please fix. Best regards -- Starting build of Custom Studies Source files: AutoTradeSignalV6DOE.cpp. -- 15:20:48 The Visual C++ compiler is not installed. Press the 'Install Compiler' button to download and install the compiler.

The last error at 2715 happens with the following code. The other errors at 2724, 2706, 2700 and 2731 use the same call process so once fixed, all can be fixed. float WriteFile(SCStudyInterfaceRef sc) { std::ofstream output; output.open ("writefile.txt", std::ofstream::out | std::ofstream::app); // insert into the file and add spaces between variables output << g_ControlLine << " " << g_ProfitFactor << " " << g_TotalPercentProfitable << " " << g_MaximumDrawdown << " " << g_MaximumTradeRunup <<" " << g_TotalTrades << " " << g_TotalLongTrades << " " << g_TotalShortTrades << "\n"; output.close(); } Date Time Of Last Edit: 2016-09-03 20:44:28

At the top of my code, I set up the call: float WriteFile(SCStudyInterfaceRef sc); |

Here are all the functions that are failing now: int ControlFile(SCStudyInterfaceRef sc) { std::ifstream input("controlfile.txt"); // set the global variables to local variables so the parameters are passed input >> g_ControlLine; } float WriteFile(SCStudyInterfaceRef sc) { std::ofstream output; output.open ("writefile.txt", std::ofstream::out | std::ofstream::app); // insert into the file and add spaces between variables output << g_ControlLine << " " << g_ProfitFactor << " " << g_TotalPercentProfitable << " " << g_MaximumDrawdown << " " << g_MaximumTradeRunup <<" " << g_TotalTrades << " " << g_TotalLongTrades << " " << g_TotalShortTrades << "\n"; output.close(); } int ProcessingFile(SCStudyInterfaceRef sc) { std::ofstream output; output.open ("processing.txt", std::ofstream::out | std::ofstream::ate); // insert into the file and add spaces between variables output << g_Processing; output.close(); } int StartProcessing(SCStudyInterfaceRef sc) { // enable or disable processing. 0 = disable, 1 = enable. Used to control when initially loading the study std::ifstream input("startprocessing.txt"); input >> g_StartProcessing; } |

At the top of my code: float ReadTradeSignalParams(SCStudyInterfaceRef sc); int ControlFile(SCStudyInterfaceRef sc); float WriteFile(SCStudyInterfaceRef sc); int ProcessingFile(SCStudyInterfaceRef sc); int StartProcessing(SCStudyInterfaceRef sc); |

There is nothing for us to fix! The Microsoft Visual C++ is a very good optimizing compiler and only gives you warnings and errors which are correct and you need to solve. You need to correct the errors and warnings in your own code. A function that has a return type other than void must return a value. It is that simple. Warnings like this can be solved with a typecast: C:\SierraChart\ACS_Source\AutoTradeSignalV6DOE.cpp(2759): warning C4244: '=': conversion from 'int' to 'float', possible loss of data Refer to: http://www.cplusplus.com/doc/tutorial/typecasting/ Sierra Chart Support - Engineering Level Your definitive source for support.

The examples I listed with code are not warnings but errors: c:\sierrachart\acs_source\autotradesignalv6doe.cpp(2724) : error C4716: 'ProcessingFile': must return a value Yes, I am willing to fix...I do not know how to fix however. |

This is what we said: A function that has a return type other than void must return a value. It is that simple. You could add a return 0; at the end. Or just simply change the return type to a void.

Got it..appreciate the quick response and suggestion....this compiler did catch other issues and my code is all cleaned up and working.
