c++ - How to check if the program is run from a console? -

i'm writing application dumps diagnostics standard output.

i'd have application work way:

if run standalone command prompt (via cmd.exe) or has standard output redirected/piped file, exit cleanly finished, otherwise (if run window , console window spawned automagically), additionally wait keypress before exiting (to allow user read diagnostics) before window disappears

how create distinction? i suspect examining parent process way i'm not winapi, hence question.

i'm on mingw gcc.

you can utilize getconsolewindow, getwindowthreadprocessid , getcurrentprocessid methods.

1) first must retrieve current handle of console window using getconsolewindow function.

2) process owner of handle of console window.

3) compare returned pid against pid of application.

check sample (vs c++)

#include "stdafx.h" #include <iostream> using namespace std; #if _win32_winnt < 0x0500 #undef _win32_winnt #define _win32_winnt 0x0500 #endif #include <windows.h> #include "wincon.h" int _tmain(int argc, _tchar* argv[]) { hwnd consolewnd = getconsolewindow(); dword dwprocessid; getwindowthreadprocessid(consolewnd, &dwprocessid); if (getcurrentprocessid()==dwprocessid) { cout << "i have own console, press come in exit" << endl; cin.get(); } else { cout << "this console not mine, bye" << endl; } homecoming 0; }

c++ c winapi

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
