output

问题 I'm having some trouble finding a way to get the results from updates/inserts/deletes/table creates... I would like to get it like you see in the SSMS (SQL Server Management Studio) message tab (guess the tool is done_in_proc). At the moment, I can get the exceptions, and I can capture the prints done in the SQL script. I already tried ExecuteScalar, ExecuteReader, ExecuteWithResults and got nothing. Thanks, Code: public void conn_InfoMessage(object sender, SqlInfoMessageEventArgs e) {

问题 I heard using gets() is bad in C programming and it's safer using fgets... So I am using fgets. However, I encounter a problem with fgets: I entered too much characters and somehow, it overflows. How to get rid of the extra input characters? char answer[4]; char answer2[4]; fgets(answer,sizeof(answer),stdin); printf("answer: %s\n",answer); fgets(answer2,sizeof(answer2),stdin); printf("answer2: %s\n",answer2); For example, for the first fgets, I enter 123456, the output I get is answer: 123

问题 I'm working on automatic C++ code testing using Python. So I have a Python script that compiles and executes C++ code. When the C++ code crashs, libc output is visible from my Python script output, even if I redirected cout and cerr of the C++ program being executed to /dev/null . Here is a sample isolating the problem: #! /usr/bin/env python # -*- coding: utf8 *-* import sys import os.path import subprocess import shutil import tempfile import string import argparse bug_folder = tempfile

问题 I am running Modelica simulations with Dymola via the Dymola Python interface. My aim is to have the result file written to textual output (i.e. to a .txt file). Even though my model contains the annotation __Dymola_experimentSetupOutput(textual=true, events=false) , the output is written to a .mat file. Unfortunately, when I type find() into the Dymola command line, I cannot find a suitable flag for setting the output format via dymola.ExecuteCommand() . Is there a possibility to set the

问题 Hi angular community, I want to fire an Event using @Output to hide or open/close a div containing others components. It's quite simple but I never use EventEmitter before, so i would like when hideDem is called it hide or open/close the div depending on other propreties comming from the child.ts child.html: <img type="button" label="Click" (click)="hideDem()" id="foldup" src="./assets/img/fold_up_blacksmall.png"/> child.comp.ts: @Output() open: EventEmitter<any> = new EventEmitter(); @Output

问题 When I'm debugging my application something is not right, and I can't continue. So is it possible to see the output code of my app while I'm testing it to see what is wrong? I open the output window but nothing happens in there it's just stay blank. In two words: I want to see what my app is actually doing while I'm testing it. I'm using Visual Studio 2010. 回答1: So is it possible to see the output code of my app while im testing it to see what is wrong? Yes, but you actually have to output

问题 I've been working on quite an ambitious function, which I hope can be used by people other than me once I am finished. When it's just me using the function I can live with the output being kind of lame, but what if I want some nice looking output? What I'm looking for is essentially this: A way of printing something readable to the console Being able to access what's printed More specifically, let's assume I have three scalar objects I want to be printed: stat , dfree and pval . Currently,

问题 Is there an option to format ansible output with the use of ansible (not any other scripts)?

Or even is there a way to get only the shell command output? 回答1: I have a plugin

问题 In this simple guess-the-number game, scanf() is not working the second time in main. I would really appreciate if someone could explain why doesn't work and how to fix it. Any tips on how to clean this code up?. Thank you! #include<stdio.h> #include<stdlib.h> #include<time.h> int guessed = 0; int guesses = 0; int total_guesses = 0; int range_top = 1; int generate_random_number() { srand(time(NULL)); return (rand() % range_top); } void take_guess(int num) { int guess; printf("what is your
