output

问题 My code (a simple console application) calls an external program (also a console application). This program spits out many things to the console, which significantly increases runtime when running in batch mode with 10,000+ iterations. I've tried several ways to disable the output: Redirecting cout and cerr to fout -> obviously works on disabling couts in the current/local program, but doesn't disable anything from an external .exe. Some sources have suggested system("cls"), but all that does

问题 I need to read a file (that is not available on web) on the server and output it to the user as a downloadable file. The scenario is The user click a link from an XPage The request is sent to the server which reads a predefined file in the server file system The file is brought back to the user as a downloadable file in the webbrowser.

问题 I am trying to output the calculated area of a triangle in this program but when I try to output the area from the function I get a mixture of letters and numbers instead of the answer, if someone could point out what I am doing wrong it would be most appreciated. I have tired tArea(area) but it gives a different error. 回答1: You aren't calling the function. When you use the tArea name without the brackets, C++ will give you the address of the function instead of calling it, and this will be

问题 Please Help. I am trying combine 2 classes (bubblesort4 and OddArrSe3), to get the answer from bubblesort4 to appear on OddArrSe3 , such as on System.out.println ("Bubble Sort : "). What I am trying to do is get the answer for the coding below: System.out.println("Array Before Bubble Sort"); for(int i=0; i < intArray.length; i++) { System.out.print(intArray[i] + " "); } bubbleSort(intArray); System.out.println(""); System.out.println("Array After Bubble Sort"); for(int i=0; i < intArray

问题 In my mapreduce job, I just want to output some lines. But if I code like this: context.write(data, null); the program will throw java.lang.NullPointerException. I don't want to code like below: context.write(data, new Text("")); because I have to trim the blank space in every line in the output files. Is there any good ways to solve it? Thanks in advance. Sorry, it's my mistake. I checked the program carefully, found the reason is I set the Reducer as combiner. If I do not use the combiner,

问题 I've made a TYPO3-Installation 6.2.9 with Fluid powered TYPO3 - the first steps with the Pre-configured Distribution "Site" were fine. My Site/Page-Template is installed and I added all the TypoScript stuff. Now I want to use FLUIDCONTENT (FCE) with FLUX. I've added a new Template-File TeaserOne.html and I try to use the Layout from the Distribution Content.html . Now I can see and write into my input-fields in Backend, but I've no Output in Frontend?! What else do I need? I only see the

问题 So the main problem is, that I can only get output programatically from SteamCmd when it terminates. The expected output would be: Redirecting stderr to 'D:\User\Downloads\TF2Server\SteamCMD\logs\stderr.txt' [ 0%] ElAęrhetAĹ frissAştAęsek keresAęse... [----] TelepAştAęs hitelesAştAęse...

问题 How can I run a command line and get the outputs as soon as available to show them somewhere. For example if a run ping command on a linux system, it will never stop, now is it possible to get the responses while the command is still processing ? Or let's take apt-get install command, what if i want to show the progress of the installation as it is running ? Actually i'm using this function to execute command line and get outputs, but the function will not return until the command line ends,

问题 I'm trying to write a python script that will allow me to take the output from a command and to put that into a file or variable (Preferability a variable). In my code, I have redirected the output to a StringIO() object. From that, I want take the output a command and to put it into that StringIO() object. Here is a sample of my code: from StringIO import StringIO import sys old_stdout = sys.stdout result = StringIO() sys.stdout = result # This will output to the screen, and not to the

问题 Is it possible to have an embedded output console as part of the VS2012 window instead of opening cmd upon running? For example, in Eclipse output is directed to the "Console" pane by default, and I would like to achieve something similar in VS2012, if it is available. 回答1: Here is a complete example of the code involved to do this: http://blog.tomaka17.com/2011/07/redirecting-cerr-and-clog-to-outputdebugstring/ Basically the author creates a new std::basic_stringbuf that uses the MSVC
