  • Error occure while validating form input using JQUERY in Firebug

    - by Param-Ganak
    Hello Friends, I have written a custom validation code in JQUERY. which is working fine. I have a login form which have two fields i.e. userid and password. I have written a custom JQUERY code for client side validation for these fields. This custom JQUERY code is working fine and gives me proper error messages as per the situation. But the problem with this code is that when I enter the invalid data in any or both field and press submit button of form then it displays the proper error message but at the same time when I checked it in Firebug it displays following error message when submit button of the form is clicked validate is not defined function onclick(event) { javascript: return validate(); }(click clientX=473, clientY=273) So please tell me where is I am wrong in my Jquery code. Thank You!

  • Foreach File in a Folder in Flash?

    - by msandbot
    Hey, I have an image slideshow program working right now and it takes in a folder of a hard coded in number of images. I would like to change this so that it can take in a folder and will display all of them no matter the number. Is there a way to do this in flash? I'm thinking something like the foreach loop in perl or other scripting language. It is possible to store then number of images in a text file but I also don't know how to read that in flash either. I'm working in actionscript 3. Any help would be greatly appreciated. Thanks -Mike

  • Using PUT/POST/DELETE with JSONP and jQuery

    - by ryanzec
    I am working on creating a RESTful API that supports cross-domain requests, JSON/JSONP support, and the main HTTP method (PUT/GET/POST/DELETE). Now while will be easy to accessing this API through server side code , it would nice to exposed it to javascript. From what I can tell, when doing a JSONP requests with jQuery, it only supports the GET method. Is there a way to do a JSONP request using POST/PUT/DELETE? Ideally I would like a way to do this from within jQuery (through a plugin if the core does not support this), but I will take a plain javascript solution too. Any links to working code or how to code it would be helpful, thanks.

  • What are the correct steps to capture data with uploadify?

    - by Curtis
    Does anyone have a demo of using uploadify with additional fields and saving to database? The site's examples don't explain the process in depth and I am not familiar with jquery. I don't know why but I can't get my head around how too integrate the two. I have the demo working and I have my app which uses traditional php/html forms working. I need to conduct basic form collection with uploadify in the mix. Collect data and check data with feedback and then process into database and post back a confirmation. How do I feed information back to the uploadify form if there is a problem from the upload.php file? How do I access my data in the upload.php file? how do I redirect the upload page to a confirmation page after a succeeful upload?

  • Secure Copy File from remote server via scp and os module in Python

    - by user1063572
    I'm pretty new to Python and programming. I'm trying to copy a file between two computers via a python script. However the code os.system("ssh " + hostname + " scp " + filepath + " " + user + "@" + localhost + ":" cwd) won't work. I think it needs a password, as descriped in How do I copy a file to a remote server in python using scp or ssh?. I didn't get any error logs, the file just won't show in my current working directory. However every other command with os.system("ssh " + hostname + "command") or os.popen("ssh " + hostname + "command") does work. - command = e.g. ls When I try ssh hostname scp file user@local:directory in the commandline it works without entering a password. I tried to combine os.popen commands with getpass and pxssh module to establish a ssh connection to the remote server and use it to send commands directly (I only tested it for an easy command): import pxssh import getpass ssh = pxssh.pxssh() ssh.force_password = True hostname = raw_input("Hostname: ") user = raw_input("Username: ") password = getpass.getpass("Password: ") ssh.login(hostname, user, password) test = os.popen("hostname") print test But I'm not able to put commands through to the remote server (print test shows, that hostname = local and not the remote server), however I'm sure, the conection is established. I thought it would be easier to establish a connection than always use "ssh " + hostname in the bash commands. I also tried some of the workarounds in How do I copy a file to a remote server in python using scp or ssh?, but I must admit due to lack of expirience I didn't get them to work. Thanks a lot for helping me.

  • How to use AFIncrementalStore to binding with a NSManagedObject

    - by Matrosov Alexander
    I am searching for more information on how to use AFIncrementalStore. I need to know how to implement it step by step. Please don't down vote it, because of many resources, I really need help with this. If I understood right AFIncrementalStore it is a layer for fetching data from the server and for the mapping data model. Am I right? So I have few URL that I need to mapping into my local model. All of them use GET requests. For example base_url/api/categories I get this string in response: [{"category":{"name":"3d max","id":"1111001","users":[]}}, {"category":{"name":"photoshop","id":"1111002","users":[]}}, {"category":{"name":"auto cad","id":"1111003","users":[]}}] So I have a question how I can binding my local db with this data using AFIncrementalStore. Also if you can see there are relationships in the response string that are connected to uses. The array for users will contain id that is correspond to concert users. So I think second question is how to point that model has to have relationship.

  • Delphi - Read File To StringList, then delete and write back to file.

    - by Jkraw90
    I'm currently working on a program to generate the hashes of files, in Delphi 2010. As part of this I have a option to create User Presets, e.g. pre-defined choice of hashing algo's which the user can create/save/delete. I have the create and load code working fine. It uses a ComboBox and loads from a file "fhpre.ini", inside this file is the users presets stored in format of:- PresetName PresetCode (a 12 digit string using 0 for don't hash and 1 for do) On application loading it loads the data from this file into the ComboBox and an Array with the ItemIndex of ComboBox matching the corrisponding correct string of 0's and 1's in the Array. Now I need to implement a feature to have the user delete a preset from the list. So far my code is as follows, procedure TForm1.Panel23Click(Sender : TObject); var fil : textfile; contents : TStringList; x,i : integer; filline : ansistring; filestream : TFileStream; begin //Start Procedure //Load data into StringList contents := TStringList.Create; fileStream := TFileStream.Create((GetAppData+'\RFA\fhpre.ini'), fmShareDenyNone); Contents.LoadFromStream(fileStream); fileStream.Destroy(); //Search for relevant Preset i := 0; if ComboBox4.Text <> Contents[i] then begin Repeat i := i + 1; Until ComboBox4.Text = Contents[i]; end; contents.Delete(i); //Delete Relevant Preset Name contents.Delete(i); //Delete Preset Digit String //Write StringList back to file. AssignFile(fil,(GetAppData+'\RFA\fhpre.ini')); ReWrite(fil); for i := 0 to Contents.Count -1 do WriteLn(Contents[i]); CloseFile(fil); Contents.Free; end; However if this is run, I get a 105 error when it gets to the WriteLn section. I'm aware that the code isn't great, for example doesn't have checks for presets with same name, but that will come, I want to get the base code working first then can tweak and add extra checks etc. Any help would be appreciated.

  • .NET Multipage Tiff with Lossy Compression

    - by Adam Berent
    I need a way to take several jpgs and convert them into a single multi page Tiff. I have that working using GDI+ however it only works with the compression LZW which is lossless. This means that my 3 50KB Jpgs turn into 3MB multipage Tiff file. This is not something I can accept for the software that I am working on. I know that Tiff Image format can use a JPG compression scheme but GDI+ does not seem to support this. If anyone knows how to do this in .NET (C#) or of any component that does this conversion.

  • Rake db:migrate returns "rake aborted! no such file to load -- spec"

    - by Isaac Yerushalmi
    For some reason, out of no where, rails began giving me an error on "rake db:migrate", and I can no longer run migrations. It returns the error "no such file to load -- spec /home/ti/rails_apps/appname/Rakefile:10" I've spent two hours searching google for answers, trying to figure this out, but to no avail.

  • How can I get .NET/Silverlight source code symbols to work in VS 2010?

    - by mattx
    Back when M$ first released the ability to point visual studio at a symbol server and actually debug into .NET code I got it up and working no problem on VS2008. Now trying to do this with VS2010 or my local copy of VS2008 doesn't seem to work. It successfully downloads the symbols and the stack frames turn from gray to black but there is no source available. Has anyone gotten this working? If so what's the secret? Also is there source available for Silverlight included?

  • pythonpath issue? "python2.5: can't open file 'dev_appserver.py': [Errno 2] No such file or director

    I added this line to my .bashrc (Ubuntu 9.10): export PYTHONPATH=/opt/google_appengine/ And then I ran the dev_appserver through python2.5 on Ubuntu like this: $ python2.5 dev_appserver.py guestbook/ python2.5: can't open file 'dev_appserver.py': [Errno 2] No such file or directory As you can see, it can't find dev_appserver.py even though it's in my /opt/google_appengine/ directory.

  • avmutablecomposition insertEmptyTimeRange

    - by smartfaceweb
    I have created an avmutablecomposition and tried to use insertEmptyTimeRange to generate 1 minute of silence. This doesn't appear to be working. I have also tried creating an avmutablecompositiontrack using addMutableTrackWithMediaType:preferredTrackID: and then insertEmptyTimeRange on the track and still no success. To give some background on my app, I allow users to add audio samples a timeline and then playback or export and this is working really well using the av classes. The problem is that I need to make sure that the audio is exactly 1 min (for example). Regardless of the info about my specific app above, is it possible to insert an empty time range into a comp or comptrack?

  • A problem regarding dll inheritance

    - by Adam
    Hello all I have created a dll that will be used by multiple applications, and have created an installer package that installs it to the program files, as well as adds it to the Global Assembly Cache. The dll itself uses log4net, and requires a xml file for the logging definitions. Therefore when the installer is run, the following files get copied to the install directory within program files: The main dll that I developed - The Log4Net.dll - the Log4Net.xml file I am now experiencing a problem. I have created a test console application for experimentation. I have added my dll as a reference, and set the 'local copy' flag to false. When I compile the test console exe however, I noticed that it has copied the log4net.dll and log4net.xml files to the bin directory. And when running the test console, it appears that it will only work if the log4net.dll is in the same directory as the exe. This is dispite the fact that the test console application does not use log4net, only the dll that was added as a reference does. Is there some way to have it so that the log4net.dll & xml files used will be the ones that were installed to the program files, rather than any application needed to copy over local copies? The applications that will be using my dll will not be using log4net, only the dll that they are referencing uses it. Many thanks

  • How to test my programming experience

    Hey guys, I'm very excited about how experienced I am in programming. The first, working program that I have written, was in 2004 with C. Since this I have tried many programming languages, now got stuck with php. Currently I'm working as a web-developer, and everyones pleased with the work I do. Except me :) Thats the reason why i want to know, how high my experience and my knowledge is. Could you tell me, some tips, tricks, test, or anything, on what I can see how much I need to learn and practice to get a mastermind in programming? (at first place in php)

  • PHP curl timing mismatch

    - by JonoB
    I am running a php script that: queries a local database to retrieve an amount executes a curl statement to update an external database with the above amount + x queries the local database again to insert a new row reflecting that the curl statement has been executed. One of the problems that I am having is that the curl statement takes 2-4 seconds to execute, so I have two different users from the same company running the same script at the same time, the execution time of the curl command can cause a mismatch in what should be updated in the external database. This is the because the curl statement has not yet returned from the first user...so the second user is working off incorrect figures. I am not sure of the best options here, but basically I need to prevent two or more curl statements being run at the same time. I thought of storing a value in the database that indicates that the curl statement is being executed at that time, and prevent any other curl statements being run until its completed. Once the first curl statement has been executed, then the database flag is updated and the next one can run. If this field is 'locked', then I could loop through the code and sleep for (5) seconds, and then check again if the flag has been reset. If after (3) loops, then reset the flag automatically (i've never seen the curl take longer than 5 seconds) and continue processing. Are there any other (more elegant) ways of approaching this?

    I am processing a file full of unix time strings. I want to convert them all to human readable.

The output I get is Thu Jan 1 00:00:00 1970 for every line. I think the line breaks are being picked up and that is why it is not working. Any ideas? I'm using Mac OSX is that makes any difference.

  • How can I tell Phusion Passenger which python to use?

    - by Mike
    I'm using Phusion Passenger with a ruby app and I'd also like to set it up to work with an django appengine app I'm working on. Googling for "passenger_wsgi.py" I was able to get the following very simple non-django app working on passenger: passenger_wsgi.py: def application(environ, start_response): response_headers = [('Content-type','text/plain')] start_response('200 OK', response_headers) return ['Hello World!\n'] However, if I add the line import django.core.handlers.wsgi into the mix, I get 'An error occurred importing your passenger_wsgi.py'. By printing out the sys.path I've discovered that at least part of the reason is because Passenger is using the wrong python installation on my machine. How can I configure Passenger (on apache) to use /opt/local/bin/python2.5 instead of the system default python?

  • Modifying SQL Database on Shared Hosting

    - by apocalypse9
    I have a live database on a shared hosting server. I am making some major changes to my site's code and I would like to fix some stupid mistakes I made in initially designing the database. These changes involve altering the size of a large number of fields, and enforcing referential integrity between tables properly. I would like to make the changes on both my local test server and the remote server if possible. I should note that while I'm fairly comfortable with writing complex queries to handle data, I have very little experience modifying database structure without a graphical interface. I can access the remote database in the visual studio database explorer but I can not use that for anything other than data manipulation. I installed Sql Management Studio express last night and after 40+ crashes I gave up - I couldn't even patch the damn thing. The remote server is SQL 2005 / The MyLittleAdmin web interface is available. So my question is what is the best way to accomplish these changes. Is there a graphical interface I can use on the remote server? If not is there an easy way to copy the database to my local machine, fix it, and re upload? Finally if none of the above are viable does anyone have links to a decent info on fixing referential integrity via query? Sorry for the somewhat general question - I feel like I am making this far harder than it should be but after searching / trying all night i haven't gotten anywhere. Thanks in advance for the help. I really appreciate it. ...Also does anyone have a time machine I can borrow- I need to go kick my past self's ass for this.

  • How do I restart mysql and where is my.cnf file

    - by dorelal
    I am using snow leopard mac. I installed mysql on my machine using instructions mentioned here. Everything works great. However I have two questions. 1) Where is my.cnf file? I searched the whole file system and result is empty. Is it possible that there is no my.cnf and mysql works with default values. If yes then probably I should create my.inf at /etc/mysql. Is that right? 2) How do I restar server. I know it gets started when I restart my machine. Here is what plist looks like. mysqld_safe does not let me restart server. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>KeepAlive</key> <true/> <key>Label</key> <string>com.mysql.mysqld</string> <key>Program</key> <string>/usr/local/mysql/bin/mysqld_safe</string> <key>RunAtLoad</key> <true/> <key>UserName</key> <string>mysql</string> <key>WorkingDirectory</key> <string>/usr/local/mysql</string> </dict> </plist>

  • Is use of LEAKS instrument still common on 3G iPhone?

    - by gordonmcdowell
    I'm working with an iPhone 3G, and when I'm trying to investigate memory leaks using the LEAKS instrument, my app crashes. It does not crash when LEAKS is not used. I'm making no claim to having a bug-free or non-memory-intensive app here. But I'd like to investigate leaks on an actual device. When I'm running LEAKS it is incredibly slow. Are there still developers working on iPhone 3G? I don't want to be the whiny guy blaming his tools, but I'd also like to be sure the whole dev world hasn't moved on to iPhone 3GS and I'm the only one trying to run both my app and leaks on a 3G. Currently running iOS 4.0 "gold". Snow Leopard dev env with latest XCode.
