• Save the output of a command in a string in linux using python

  - by user1657901

  I am using Fedora 17 xfce and I am programming in Python 2.7.3. Fedora uses a package manager called yum. I have a python script that searches for packages like this: import os package = raw_input("Enter package name to search: ") os.system("yum list " + package) So I want python to check if in the output of this command exists the words "No matching packages to list". I checked a similar question and I tried some methods [http://stackoverflow.com/questions/2502833/python-store-output-of-subprocess-call-in-a-string][1] but the string contained only the first line of the output. Thanks in advance

• How can I open another tab in the browser from the Code Behind [duplicate]

  - by Daniel Powell

  This question already has an answer here: Response.Redirect to new window 18 answers I have an ASP.Net project that I am working on that involves opening another tab in the browser from the vb.net (code behind). I have tried to use the WebBrowser control to open the new tab as well as tried to use the Script manager however I have not been able to open the new tab. The button I am using is a custom button in a DevExpress GridView, and I am handling its click with this code: Private Sub ASPxGridView2_CustomButtonCallback(sender As Object, e As DevExpress.Web.ASPxGridView.ASPxGridViewCustomButtonCallbackEventArgs) Handles ASPxGridView2.CustomButtonCallback If e.ButtonID <> "customButton" Then Return End If Dim neededID = ASPxGridView2.GetRowValues(e.VisibleIndex, "target") Dim id = CStr(neededID) Dim url = ("targetPage.aspx" + "?ID=" + id) Dim wb As WebBrowser wb.Navigate(url,True) End Sub I'm not sure why this would not work, any suggestions as to how I should open a new browser tab with or without the WebBrowser works for this project. EDIT: I cannot use javascript with this ASPxGridview So I need an answer that doesn't involve modification to the javascript except through the vb.net code behind

• NSIS- Error handling

  - by Pia

  I have written an installer and uninstaller in NSIS which creates and drops an sql database, which is working fine. I have written some .bat and .sql files to create and drop the database and then just call these files from NSIS script. My problem is if I keep this database open in SQL Server Management Studio and run the uninstaller ideally it should give an error message that the database is opened. In my case it shows the success message of uninstaller but dosnt drop the database properly. How can I handle this error in NSIS?

• What's the most auditable way to organize database maintenance scripting/scheduling?

  - by RenderIn

  I'm using PHP, Oracle and crontab. Crontab is invoking a php script, which is going to synchronize some data between a local and remote database. First I thought about putting this all in one large, anonymous inline PL/SQL block and executing it in PHP. The problem is that without creating a table to audit the procedure it's really opaque to my PHP code until it returns. And then when it does return, the best I can do is receive a string in an out parameter which I've concatenated together as an audit log. Then I considered breaking it up into several SQL statements and have PHP do some intermediate auditing/logging and manipulation of the data between each of them. I'm not really satisfied with either of these. How do you organize maintenance code that is called in a cronjob?

• Scheduling a visual studio load test using powershell giving me BSOD

  - by user952342

  I have a visual studio load test which I want to run every hour so that I can start to collect some data. To do this, I thought it would be best to make a little powershell script and put a command like this inside: Invoke-Expression -command "& '$env:VS100COMNTOOLS..\IDE\mstest.exe' /testcontainer:"C:\Users\benb\Documents\Visual Studio 2010\Projects\BBPerformanceTest\bin\Debug\HomePageOnly.loadtest"" That command works fine, but sometimes when its run I get a blue screen of death. However, when I run my load test through the visual studio GUI, I never get a BSOD. two questions: is it possible to avoid this BSOD? Is there another way I can schedule my load test? Thanks

• Print the next X number of lines in Scala

  - by soulesschild

  Trying to learn Scala using the Programming in Scala book and they have a very basic example for reading lines from a file. I'm trying to expand on it and read a file line by line, look for a certain phrase, then print the next 6 lines following that line if it finds the line. I can write the script easily enough in something like java or Perl but I have no idea how to do it in Scala (probably because I'm not very familiar with the language yet...) Here's the semi adapted sample code from the Programming in Scala book, import scala.io.Source if(args.length>0) { val lines = Source.fromFile(args(0)).getLines().toList for(line<-lines) { if(line.contains("secretPhrase")) { println(line) //How to get the next lines here? } } } else Console.err.println("Pleaseenterfilename")

• Deny access to a PHP file (Nginx)

  - by Desmond Hume

  I want Nginx to deny access to a specific PHP file, let's call it donotexposeme.php, but it doesn't seem to work, the PHP script is run as usual. Here is what I have in the config file: location / { root /var/www/public_html; index index.php; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/public_html$fastcgi_script_name; include fastcgi_params; } location /donotexposeme.php { deny all; } Of course, I do sudo service nginx reload (or restart) each time I edit the config.

  I need to parse a large log file (flat file), which contains two column of values (column-A , column-B). Values in both columns are repeating. I need to find for each unique value in column-A , I need to find a set of column-B values. Is this can be done using unix shell command or need to write any perl or python script?

• PHP File Upload + jQuery

  - by st4ck0v3rfl0w

  Hello Everyone, So I have my upload script working just fine, but now it's a matter of making it look the way I want for my layout. <input type="file" name="userfile" id="userfile"/> This obviously shows a textbox with a Choose File button.

I do NOT want the filename textbox to show. Basic steps outlined below. User clicks on image button to upload their file User selects file jQuery shows a div with more fields User clicks submit and file is uploaded

• missing ) in parenthetical

  I'm modifying BSN's Autosuggest script so it will work with codeigniter, the only proble is I cant seem to figure out why it displays "missing ) in parenthetical" says the problem is around else _b.AutoSuggest.prototype.setSuggestions = function (req, input) { if (input != this.fld.value) return false; this.aSug = []; if (this.oP.json) { var jsondata = eval('(' + req.responseText + ')'); for (var i=0;i<jsondata.results.length;i++) { this.aSug.push( { 'id':jsondata.results[i].id, 'value':jsondata.results[i].value, 'info':jsondata.results[i].info } ); } } else { var xml = req.responseXML; // traverse xml // var results = xml.getElementsByTagName('results')[0].childNodes; for (var i=0;i<results.length;i++) { if (results[i].hasChildNodes()) this.aSug.push( { 'id':results[i].getAttribute('id'), 'value':results[i].childNodes[0].nodeValue, 'info':results[i].getAttribute('info') } ); } } this.idAs = "as_"+this.fld.id; this.createList(this.aSug); }; Any help would be appreciated, i'm not very good at JS

• Loading jQuery multiple times in the same page

  - by Winaji

  I'm implementing a plug-in that's embeddable in different sites (a la Meebo, Wibiya), and I want to use jQuery. Problem is, the site I'm embedding to, may already have a jQuery script loaded. The question is, what's the best approach for this kind of problem: Should I just check if jQuery is already loaded and if so, use the original site's jQuery, otherwise load it myself? If I use this approach, am I not risking comaptibility problems (i.e. the site uses an old version of jQuery)? Should I load jQuery myself (whether it's already loaded or not) and call "jQuery.noConflict(true)" when it's finished loading? If so, how can I make sure that my jQuery has finished loading (hooking to the onLoad event doesn't seem to work all the time, and polling for "jQuery" won't work for obvious reasons)? Should I do something else? Thanks.

• How do I change the Unit:Characters in Matlab?

  - by Jonas

  For portability, I set the units of my GUIs to 'characters'. Now I have a user who wants to use Matlab on his netbook, and the GUI window is larger than the screen (and thus cropped at the top). I think I could try and write something in the openingFcn of the GUI that measures screen size and then adjusts the GUI accordingly, but I'd rather avoid that, because I then need to deal with text that is bigger than the text boxes, etc. What I'd rather like to do is somehow adjust the unit 'character' on his Matlab installation. None of the font sizes in the preferences seem to have an effect on unit:character, though. Does anyone know whether there's a setting for that, which can be changed from within Matlab (I don't mind if it's something that is reset at every reboot, since I can just put it into the startup script)?

• Using ManagementClass.Getinstances() from IronPython

  - by Leo Bontemps

  I have an IronPython script that looks for current running processes using WMI. The code looks like this: import clr clr.AddReference('System.Management') from System.Management import ManagementClass from System import Array mc = ManagementClass('Win32_Processes') procs = mc.GetInstances() That last line where I call the GetInstances() method raises the following error: Traceback (most recent call first): File "<stdin>", line 1, in <module> SystemError: Not Found I am not understanding what's not being found?!? I believe that I may need to pass an instance of ManagementOperationObserver and of EnumerationOptions to GetInstance() however, I don't understand why that is, since the method with the signature Getinstance() is available in ManagementClass.

• How can I fix Grails error: "No domain class found for name PrivacyOptions. Please try again and e

  - by ?????

  I'm just getting started with Groovy/Grails. I added a new domain controller to my project, and generate-controller doesn't like it. There are other indications something's wrong: If I run the app no table is actually created in the database for this. I've reduced the DomainController to one String field and no constraints, just to make sure there wasn't something wrong with my specification. I also tried renaming it, just in case there was something about the original name (Privacy) that conflicted with something. I'm sure I have the correct name, and that the file is called PrivacyOptions.groovy and inside the class is also called PrivacyOptions. Here's the error: Running script /opt/local/grails/scripts/GenerateController.groovy Environment set to development Domain class not found in grails-app/domain, trying hibernate mapped classes... No domain class found for name PrivacyOptions. Please try again and enter a valid domain class name

• Self-contained python installation with executable tools included (pip, orbited, etc)

  - by Tristan

  I'm trying deploy a Python application on Windows as a folder that includes a full python 2.6 folder. I don't need/want a fancy solution like py2exe, I'm just trying to automate deployment of a web application. So long as I include python26.dll and set the PYTHONHOME correctly, things seem to work if I just include the Python26 folder in its entirety. However a number of the Python26/Script files don't work. For instance, pip.exe, orbited.exe, and morbid.exe all do nothing (complete with no output) when I try to run them on a system that doesn't have a real Python26 installation. I've run out of ideas. Suggestions?

• Jquery Match() IP Address?

  - by user1635970

  I'm using a jquery script to validate form fields. This works well, but I'd like to change the validation of one field to check for IP Addresses. The regex I want to use is : \b(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\b How do I amend the below to work with this ? (This is how the validation works for email address) jQuery("#Email").validate({ expression: "if (VAL.match(/^[^\\W][a-zA-Z0-9\\_\\-\\.]+([a-zA-Z0-9\\_\\-\\.]+)*\\@[a-zA-Z0-9_]+(\\.[a-zA-Z0-9_]+)*\\.[a-zA-Z]{2,4}$/)) return true; else return false;", message: "Should be a valid Email id" });

• Confused by "let" in Clojure

  - by Tom Dalling

  I just started playing with Clojure, and I wrote a small script to help me understand some of the functions. It begins like this: (def *exprs-to-test* [ "(filter #(< % 3) '(1 2 3 4 3 2 1))" "(remove #(< % 3) '(1 2 3 4 3 2 1))" "(distinct '(1 2 3 4 3 2 1))" ]) Then it goes through *exprs-to-test*, evaluates them all, and prints the output like this: (doseq [exstr *exprs-to-test*] (do (println "===" (first (read-string exstr)) "=========================") (println "Code: " exstr) (println "Eval: " (eval (read-string exstr))) ) ) The above code is all working fine. However, (read-string exstr) is repeated so I tried to use let to eliminate the repetition like so: (doseq [exstr *exprs-to-test*] (let [ex (read-string exstr)] ( (do (println "===" (first ex) "=========================") (println "Code: " exstr) (println "Eval: " (eval ex)) ) )) ) But this works once for the first item in *exprs-to-test*, then crashes with a NullPointerException. Why is the addition of let causing the crash?

• Perl array and hash manipulation using map

  - by somebody

  I have the following test code use Data::Dumper; my $hash = { foo => 'bar', os => 'linux' }; my @keys = qw (foo os); my $extra = 'test'; my @final_array = (map {$hash->{$_}} @keys,$extra); print Dumper \@final_array; The output is $VAR1 = [ 'bar', 'linux', undef ]; Shouldn't the elements be "bar, linux, test"? Why is the last element undefined and how do I insert an element into @final_array? I know I can use the push function but is there a way to insert it on the same line as using the map command? Basically the manipulated array is meant to be used in an SQL command in the actual script and I want to avoid using extra variables before that and instead do something like: $sql->execute(map {$hash->{$_}} @keys,$extra);

• Executing ffmpeg from php running in apache

  - by foobar

  I was executing ffmpeg from php running inside apache. I used to get the error " error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory". It used to work perfectly if the php script was executed from the command prompt or ffpmeg was directly invoked from the command prompt. I followed the below steps to fix the apache error: Step 1: Check if the file “libavdevice.so.52? exists in the server using the following command. find / -name ‘libavdevice.so.*’ Step 2: You will get the directory in which the file “libavdevice.so.52? exists from the above command. Suppose the directory is “/usr/local/lib/” in this example. Step 3: You have to add the directory name in the file “/etc/ld.so.conf”. Step 4: Execute the command “ldconfig”. How did doing the above make a difference to apache?

  My problem is that I have too many files in single directory. I cannot "ls" the directory, cos is too large. I need to move all files in better directory structure. I'm using the last 3 digits from ID as folders in reverse way. For example ID 2018972 will gotta go in /2/7/9/img_2018972.jpg. I've created the directories, but now I need help with bash script. I know the IDs, there are in range 1,300,000 - 2,000,000. But I can't handle regular expressions. I wan't to move all files like this: /images/folder/img_2018972.jpg -> /images/2/7/9/img_2018972.jpg I will appreciate any help on this subject. Thanks!

• WMCI - how to get the ERRORLEVEL

  - by murxx

  Hi, I want to use the "wmic" command for finding out if a specific java process is still up and running. E.g. wmic process where "commandLine like '%ACTMonitor%' and executablePath like '%PATH1%' and name like '%java%'" The problem now is that the errorlevel of this command is always 0, no matter if there is a process listed or not. How can I manage to get an errorlevel != 0 in case the process is not up anymore? Or can one of you tell me another suggestion on how to be able to continue in a .bat script with this information... Thanks in advance!

• How do you make a WiX project build when dependent files have changes?

  - by Scott Langham

  Hi, I've adopted a Visual Studio solution that contains a number WiX projects. We build the solution from an MsBuild script to generate the product's installer msi. The problem I'm experiencing is that if I build (and don't rebuild), even if exe's and dll's get updated that need to be put in the installer, the WiX build system doesn't seem to detect this and skips building the installer as it thinks it's already up to date. How do I work out what the dependencies are that are needed to build a WiX project, and how do I tell the Wix build system to watch out for them changing so it knows to build instead of skip?
