output

问题 I have adapted an existing Powershell script to query a list of servers for logged in (or disconnected) user sessions using quser /server:{servername} and output the results into a CSV file. It does output any logged in users but what it doesn't capture is servers that had 0 users or weren't accessible (server offline, rpc not available, etc.). I'm assuming that is because these other conditions are "errors" rather than command output. So if it hits a server with no users it outputs "No User

问题 I'm having trouble with output in for each function in PHP (actually don't know how to set the code to do what I need). I'd like to output some text if every item in foreach is equal to some value. If I put foreach($items as $item) { if($item == 0){ echo "true"; } } I will get true for every item and I need to output true only if all items are equal to some value. Thanks! 回答1: This peice of code work for most type of variables. See how it works in inline comment. $count=0; // variable to

问题 [ NOTE : this question is a spinoff of an earlier question of mine. At the time I posted that earlier question I did not realize that it actually asks about two different issues. Thanks to a comment by tripleee, I figured out the answer to one of the two. The question below limits itself to the remaining problem.] I'll use the short demo script below to illustrate the problem. # -*- coding: utf-8 -*- use strict; use feature 'unicode_strings'; use POSIX 'locale_h'; use locale; use utf8;

问题 I'm using R formattable package to render some data frames but the output is html ( it opens the browser after I run the script ). The thing is I'm trying to render those tables under PowerBI which accepts R scripts but need the output to be an image (like a ggplot) not html. But I don't know how I can do it. I've looked into R2HTML and htmlwidgets packages but I still didn't find a solution with those. ( I may have made some mistakes ). Here is the dummy code I'm working with: library

问题 I am having the following code and print.xtableFtable ignores the additional options for latex. ##### Contingency tables - 34Y library(xtable) B <- ftable(prereg34Y_sub$employmentStatus34Y, prereg34Y_sub$ethnicity34Y, dnn=c("Unemployed", "NonBritish")) sink("CTFemaleNonBrit34Y.tex", type="output") print.xtableFtable(xtableFtable(B, method = "compact"), table.placement = "h!") sink() The output is: % latex table generated in R 3.3.1 by xtable 1.8-2 package % Sat Oct 22 18:08:35 2016 \begin

问题 I would like to get the number of row affected / deleted / updated with a TMSSqlRow. Here is how the job is: the file use contains a lot of sql statement like DELETE ... INSERT ... UPDATE... each row are separate by ";" But now, I would like to get result of each statement (x rows updated, like results are display in management studio). When I go to "advanced settings" tab of tmssqlrow, I select " Propagate QUERY's recordset" and select a column I created before (Object Type). On execution, I

问题 I'm a bit confused. The PHP documenation says: // Example usage for: Null Coalesce Operator $action = $_POST['action'] ?? 'default'; // The above is identical to this if/else statement if (isset($_POST['action'])) { $action = $_POST['action']; } else { $action = 'default'; } But my own example says something very different: echo "<pre>"; $array['intValue'] = time(); $array['stringValue'] = 'Hello world!'; $array['boolValue'] = false; $resultInt = isset($array['intValue']) ?? -1; $resultString

问题 I've placed File.rtf in the directory library/Developer/Xcode/DerivedData/Test(projectname)/Build/Products/Debug and the code seems to open it but prints out the wrong output.The output is 1606422622 for any integer value in the file. Going through the solutions of question similar to mine ,the answers were to get the input file in the right directory.I think I've done that but I just can't get the correct output. Desperate for help.Thanks. int main() { int b; FILE *fp; fp=fopen("File.rtf","r

问题 I'm learning how to develop for iPhone and i need to save de NSLog output on a local file on my machine to analyse the result in because I`ll run the application for a long time and I need to check after some hours running what was the output (and I want to save the output file on my machine from time to time, for example after every 30min). How can I save the xcode output into a file? 回答1: Possibly not what you want, but I use this: - (void)logIt:(NSString *)string { // First send the string
