Ok, so I'm having a problem trying figure out the problem in my code. I have a lot of code so I'm only going to post the relevant parts that are messing up when I compile. I have the following function inside of a class and it will compile and everything will run fine until I call the function "CalculateProbabilityResults" and it runs the 7th line of code within it. I've "de-commented" this line of code in my program so you can find it easier. I'm pretty sure I have the right #include directives needed since it compiles fine when not calling the function, so that can't be the problem can it? I know some of my naming notation needs a little help, so please bear with me. Thanks in advance for the help guys.
int SQLServer::CalculateProbabilityResults(int profile, int frame, int time_period, int TimeWindowSize) { ofstream ResultFile; stringstream searchFileName; stringstream outputName; vector<vector<int>> timeFrameItemsets; int num = getTimeFrameFile(frame*TimeWindowSize, TimeWindowSize); cout << num << endl; //outputName << "Results" << getTimeFrameFile((frame*TimeWindowSize), TimeWindowSize) << ".csv"; cout << outputName.str() << endl; outputName.clear(); //ResultFile.open(outputName.str().c_str()); ResultFile.close(); result.resize(0); return 0; } int getTimeFrameFile(int timeInHours, int timeFrameSize) { int fileNum = 0; int testWin; if (timeInHours > 24) { while (timeInHours >24) timeInHours -= 24; } for (testWin = 0; testWin < 24/timeFrameSize; testWin++) { if (timeInHours >= testWin*timeFrameSize && timeInHours < (testWin+1)*timeFrameSize) fileNum = testWin+1; } if (fileNum == 0) fileNum = testWin+1; return fileNum; } Call Log
