command-line-arguments

问题 I am trying to convert an exe to dll and manually call the main function from the DLL in my C++ program. The main function in the code of this exe (generated from another C++ program) looks like this: int main(int argc, char* argv[]) Now, in my C++ program, earlier I was passing the command line arguments to this exe as follows: system(somexe test.txt test1.txt test2.txt); The int argc and argv array are automatically then passed to the exe program. However, I am not sure as to how I would be

问题 I need to select the monitor my game is displayed on from the command line for dual monitor systems. If I use the Unity Screen Selector Dialog it gives me the choice of which monitor I want to display the game on when starting the game, and it works fine. When I try loading the game from the command line with the command line argument: "MyGame -adapter 1" or "MyGame -adapter 2" it seems to ignore the argument, and just loads the game on the same monitor every time. Notes: I have a dual

问题 I've just noticed a pattern (in git and the CommandLineParser lib for .NET) for verb-style command arguments, and wondering if someone can confirm: myprog dothis -a "someArg" -a --arg What's the difference between the single-dash-prefix and the double-dash-prefix? Is the single dash prefix always for a single-letter argument specifier, where a double dash prefix always for a "long name" of the argument? Is there a formal convention somewhere that drives this, or is it a generally accepted

问题 To make a long story short, I found out that I must start my java applications without "-XstartOnFirstThread". However, Eclipse provides this argument to any java application started via Eclipse (see Properties of the running application in debug-mode). I can't see where these default arguments come from and how I can adjust or remove them. The argument fields in the "Run Configurations" are empty and the fields for the default arguments for my current JRE are empty as well (can be found via

问题 I am using autohotkey to automate some manual process. I have to run a java command line program(.java) that accepts couple of command line arguments. I want to run this java program from autohotkey after executing some pre-defined tasks in the automation. How would I do this? 回答1: I think that this is what you are looking for. In this example, I over-ride the company default search engine inside IE. #i::Run "C:\Program Files\Internet Explorer\iexplore.exe" http://www.google.com Basically,

问题 I have an app that I'm trying to run elevated on windows 7 and windows xp thin clients but I cant seem to get the runas.exe cmd line correct. I know I need the backslash escape character in there so runas interprets the spaces correctly. This works when sending runas a single argument that has been escaped with a backslash. This scenario is all I found as a solution and it works however, I need to send multiple arguments that are all escaped with backslashes because of spaces in the

问题 While brushing up on bash (it's been a while), I was surprised to notice that executing this code, saved as script.sh: echo "Arg 0 to script.sh: $0" echo "Arg 1 to script.sh: $1" function echo_args { echo "Arg 0 to echo_args: $0" echo "Arg 1 to echo_args: $1" } echo_args like this: >> ./script.sh argument output this: Arg 0 to script.sh: ./script.sh Arg 1 to script.sh: argument Arg 0 to echo_args: ./script.sh Arg 1 to echo_args: I was surprised to see that $0 of script.sh was passed as $0 to

问题 please forgive me if this is a noob question, but i'm a beginner at C, learning only for a while. I tried to write a program that sums up two numbers (provided as params to the application). The code is like this: #include <stdlib.h> #include <stdio.h> int main( int argc, char** argv) { int a = atoi(argv[0]); int b = atoi(argv[1]); int sum = a+b; printf("%d", sum); return 0; } But I get incorrect results - huge numbers even for small inputs like 5 and 10. What is wrong here? 回答1: The first

问题 Package Settings I have built a Python package which uses nose for testing. Therefore, setup.py contains: .. test_suite='nose.collector', tests_require=['nose'], .. And python setup.py test works as expected: running test ... ---------------------------------------------------------------------- Ran 3 tests in 0.065s OK Running with XUnit output Since I'm using Jenkins CI, I would like to output the nose results to JUnit XML format: nosetests <package-name> --with-xunit --verbose However,

问题 My Requirement: For now when I run my python application with this command python main.py -d listhere/users.txt The program will run and save the result file as predefined name say reports.txt Now I want to add this functionality to allow users to choose what to put the filename and where to save as so python main.py -d -o output/newfilname -i listhere/users.txt Everything is same but I want another argument -o to be passed which will determine the filpath and name to be saved. How do I do it
