warnings

问题 I get an InputConnectionWrapper warning everytime I turn off the screen when my app is visible. I don't know why, because I don't use InputConnection . Here is the LogCat Output. 09-07 14:21:31.716: W/IInputConnectionWrapper(24197): getExtractedText on inactive InputConnection 09-07 14:21:31.724: W/IInputConnectionWrapper(24197): getExtractedText on inactive InputConnection 09-07 14:21:31.724: W/IInputConnectionWrapper(24197): getTextBeforeCursor on inactive InputConnection 09-07 14:21:31.724

问题 In Xcode, whenever I see warnings (usually about misplaced elements) appear in the XIB / Storyboard, I have to: Select the container (Usually the containing view controller or the top most view) From the Xcode menu select Editor -> Resolve Auto Layout Issues -> All views in <container name> -> Appropriate action ( For instance: Update frames ) to resolve the issues. The above method takes requires steps and a bit time consuming to me. It would be great if I could: - Resolve all warnings for

问题 I just uploaded my website on the production server and i get the error : Warning: mysql_real_escape_string(): Access denied for user 'www-data'@'localhost' (using password: NO) in file.php on line 106 Warning: mysql_real_escape_string(): A link to the server could not be established in file.php on line 106 the code of the function is include('./../inc/conn.php'); if(isset($_GET['query']))$q = clean($_GET['query']); function clean($var){ return(mysql_real_escape_string($var)); } the code of

问题 I am pairing up online guides with an old text to learn R (page 182 - http://cran.r-project.org/doc/contrib/Faraway-PRA.pdf). When I use data from a package from R (as in the tutorial examples) there is no problem. However, when I use data from my text, I always end with no F-value and the warning. Take a look: data into a data.frame: car.noise <- data.frame( speed = c("idle", "0-60mph", "over 60"), chrysler = c(41,65,76), bmw = c(45,67,72), ford = c(44,66,76), chevy = c(45,66,77), subaru = c

问题 I have recently updated to Xcode 7 and now receive the following warning when I compile: ld: warning: -read_only_relocs cannot be used with x86_64 I don't think I changed anything in the build settings or code to create this. Does anyone know what is causing this warning and how to remove it? 回答1: I have found the problem for those interested. As mentioned in the comment, I'm using the Twilio API and if you install this via cocoapods it adds the -read_only_relocs flag to the Other Linker

问题 I've seen plenty of posts providing the -W0 flag as an answer to this issue, but I don't want to suppress all warnings, just warnings of a particular value. I'm running a non-rails app (which uses ActiveRecord, notwithstanding) on Ruby 1.8.7. I want to keep all warnings except for the following DEPRECATION WARNING: Object#id will be deprecated; use Object#object_id If that's not possible, I'd like to jettison all deprecation warnings. Java, at least, lets you do this. How about Ruby? Update:

问题 In Odoo 8, I am using a custom module which checks that VAT is unique, using @api.constrains('vat', 'parent_id', 'company_id'), and raising a warning when vat already exists. But in the website purchase checkout form, I am making the customers enter the VAT. It happens that when a repeated VAT is entered I get a 500 internal server error, since the website does not provide a way to raise the warning. How should I implement a warning, a pop-up or similar in order to avoid those internal server

问题 On some paint events, Qt outputs several warnings in the console: "QPainter::begin: Painter already active" I would like to disable this particular warning because it clutters the Output window and I'm not planning to fix it. How can I do that? 回答1: The only way to do it is to remove it from the Qt sources and recompile them. But it would be much easier and reliable to just fix the cause. P. S. Actually, as noted in the other answer, it is possible to install an msg handler and filter out
