How to find error, when GetErrorCode returns 0!!!

New comment
 

Hi

I have created an indicator class and when run it on a testing EA, following methods returns correct values:

double CiPivots::GetIndexPivots(int pBuffer,int pIndex) {

                string vMethod = "[" + mSymbol + "," + EnumToString(mPivotTimeFrame) + "] " + __FUNCTION__;
                double arrayData[1];                                                                                                    // LOCAL STATIC BUFFER TO RETURN SINGLE INDEX VALUE

                if(CopyBuffer(mHandlePivots,pBuffer,pIndex,1,arrayData) == -1) {
                        ResetLastError();
                  PrintFormat("%s: Error[#%i] getting iPivots for _buffer[#%i] value at Index[%i]",vMethod,GetLastError(),pBuffer,pIndex);
                  return(0.00);
                }
                return(NormalizeDouble(arrayData[0],mDigits));

} // END Of method GetIndexPivots()

However when I am using it in an another class it keeps returning error 0. I have checked there is no error of indicator handle (INVALID_HANDLE)

Any clues how can I find out what is going wrong!!!

Thanks in advance.

'periodD1' is from custom ENUM_TIMEFRAMES and on buffer no 4,5,6 have been called.

You are resetting error code to zero before printing. 

Use code styler or manually fix indentation and it will be easier to spot potential problems.

Thanks a lot @Drazen Penic

It was really a silly mistake by me.

I have moved ResetLastError() above if(CopyBuffer) and get the error code now.
