  • How do I prevent form from redirecting after submission?

    - by Noor
    I have searched the site and I've found various solutions, most of them suggesting using return false; Problem is that I'm using this piece of code to submit the form: $(function() { $("#snd").click(function() { var dendar = "http://" + $("#inpt").val() + ":" + $("#pwd").val() + "secretsite.lol/something.xml"; $("#formen").attr("action", dendar); $("#formen").submit(); alert(dendar); return false; }); }); The alert is just there to let me know that the form has been submitted.. Thanks guys!

  • Get DataGridView checkbox cell value?

    - by George
    Hello guys. I'm having a strange issue here. I have a 3 column datagrid that is filled by a connection with the database. So far so good. I have an extra column, of checkbox type. I need to get it's value for perfoming a bulk operation on it. Here is the catch: When all cells are selected, it works fine. But when an user selects any cell that its not the first, software gives me a object reference exception. Here is the code public List<String> GetSelected() { List<String> selected = new List<String>(); foreach(DataGridViewRow row in datagrid.rows) { if ((Boolean)row.Cells[wantedCell].Value == true) { selected.Add(row.Cells[anotherCell]); } } } I tracked down the failure to the if-test, throwing a exception, because the value of the cell is read as null. Any thougths? Thanks

  • which layout engine for finding coordinates of html elements on the web page?

    - by Mexx
    I am doing some web data classification task and was thinking if I could get the co-ordinates of html elements as they would appear on a web-browser without taking into consideration any css or javascript being referred in the web page. My language of programming is c++ and the need results for a couple million of pages, so it has to be fast. I know there is a Microsoft COM component which renders the page in a web browser control and then can be queried for position of different html tags. But this is not suitable in my case as it first renders the whole page which takes up a lot of time. So as I found out, there are open-source layout engines WebKit, Gecko that can probably be used for this. But that's a huge piece of code and I need someone to direct me to the right classes or right modules to look into or any previous/similar work someone has done previously. Also, please let me know what you guys think is a good choice if I want to customize the existing code for use with multiple threads to make it faster. Thanks

  • discovering files in the FileSystem, through SSIS

    - by cometbill
    I have a folder where files are going to be dropped for importing into my data warehouse. \\server\share\loading_area I have the following (inherited) code that uses xp_cmdshell shivers to call out to the command shell to run the DIR command and insert the resulting filenames into a table in SQL Server. I would like to 'go native' and reproduce this functionality in SSIS. Thanks in advance guys and girls. Here's the code USE MyDatabase GO declare @CMD varchar(500) declare @EXTRACT_PATH varchar(255) set @EXTRACT_PATH = '\\server\share\folder\' create table tmp_FILELIST([FILENUM] int identity(1,1), [FNAME] varchar(100), [FILE_STATUS] varchar(20) NULL CONSTRAINT [DF_FILELIST_FILE_STATUS] DEFAULT ('PENDING')) set @CMD = 'dir ' + @EXTRACT_PATH + '*.* /b /on' insert tmp_FILELIST([FNAME]) exec master..xp_cmdshell @CMD --remove the DOS reply when the folder is empty delete tmp_FILELIST where [FNAME] is null or [FNAME] = 'File Not Found' --Remove my administrative and default/common, files not for importing, such as readme.txt delete tmp_FILELIST where [FNAME] is null or [FNAME] = 'readme.txt'

  • VLC helper protocol on Mac OS X

    - by Preben
    Hey everybody, I am trying to add a vlc:// helper protocol on Mac OS X. To register the protocol, I have unsuccessfully been playing around with the MoreInternet PrefPane. What I want to have in my browser is a vlc://someressource.com/audio.mp3, which should launch VLC and add http://someressource.com/audio.mp3 to the playlist (this works fine on Windows and also Linux if I remember correctly). Maybe even just have vlc://http:// so that https would also be supported. I have no idea how to achieve this. I tried making a bash script, which MoreInternet would not accept. Then I tried making an application through Automator with my Bash script embedded. That did not work either, as the Automator application has no "creator code" - whatever that is?! Can any of you guys point me in the right direction? Thanks in advance!

  • Parent-Child relation while using object data source

    - by Saba
    Hello guys I am experiencing with a class generator I've written, which generates a class for each table in database with each table field as a property and such. Before that, I used to add a typed dataset to the project and add some tables to it. It automatically detected the relationship between tables and when I added a parent table as data source of a datagrid, I could add another datagrid and use the foreing key data member of it's bindingsource to fill it, and when someone moved the focus on parent datagrid, the data in child datagrid would change accordingly. Now that I have my classes, I add an object as data source for my 2 datagrids, but obviously it doesn't detect a parent child relation. But It'd really help if I could have that foreign key relation in my object datasources. Is there any way to have that relation in object datasource?

  • how to cast an array of char into a single integer number?

    - by SepiDev
    Hi guys, i'm trying to read contents of PNG file. As you may know, all data is written in a 4-byte manner in png files, both text and numbers. so if we have number 35234 it is save in this way: [1000][1001][1010][0010]. but sometimes numbers are shorter, so the first bytes are zero, and when I read the array and cast it from char* to integer I get wrong number. for example [0000] [0000] [0001] [1011] sometimes numbers are misinterpreted as negative numbers and simetimes as zero! let me give you an intuitive example: char s_num[4] = {120, 80, 40, 1}; int t_num = 0; t_num = int(s_num); => 3215279148 ?????? the result should be 241 but the output is 3215279148? I wish I could explain my problem well! how can i cast such arrays into a single integer value?

  • Looking for a file database

    - by Mitchell Skurnik
    A few years ago there was a PHP script around called paFileDB. Essentially it created a database of files that end users could download and rate. It would keep track of the number of downloads as well. I am looking for a replacement of this coded in ASP.net C#. For the last week I have been searching around for "asp.net C# file database" and have just gotten how to upload files to a database. I have also search with some other terms. I do not need a full blown CMS like DotNetNuke or SharePoint. All I have been looking for is a system I could easily add to my existing .net C# site. I have thought about coding one myself, but with me being rather busy at work and this being a personal project, I simply do not have the time to code this myself. I hope that you guys can help. Thank you!

  • C# Design a class with interface?

    - by Haroon
    I am having a bit of trouble understanding how I will design a class. My class will have 3 methods ICollection<Field> GetFields(); //perform validation internally - return back the object T UpdateFields(ICollection<Field> fields); //pass in model object with values on it, set up fields, then pass back all fields ICollection<Field> GetFieldsWithValues(T object); What is the best way to construct/design such a class keeping in mind: 1. The model object I pass in will be one of 3 or 4 tables, however when I call GetFIelds - internally for each object I know what fields will be there i.e. list.add(new Field{name = "id", value = "5"}); list.add(new Field{name = "nameofcompany", value = "super guys"});

  • FastCGI C++ program and missing SCRIPT_NAME

    - by Simone Margaritelli
    Hi guys, i'm studying the fastcgi developement kit because i'm writing a new scripting language and i'd like to write a fastcgi version of the interpreter to run scripts as webpages. I'm using this example from the sdk, located at /srv/http/bin/echocpp So, in my httpd.conf file, i have the following lines : FastCgiServer /srv/http/bin/echocpp -idle-timeout 120 -processes 4 ScriptAlias / /srv/http/bin/echocpp/ ... ... AddHandler fastcgi-script hy Where 'hy' is the extensions of my scripts. Then, when i try browse, for instance http://localhost/~evilsocket/prime.hy I see all the environment variables as expected from the echo-cpp.cpp programm, except for the SCRIPT_NAME that is empty. Is there something i'm missing out of this? How am i supposed to obtain the full path of the script to run it inside my fastcgi version of the interpreter? Thanks

    - by Gublooo
    Hey guys I'm using Jquery flowplayer tools overlay to open external links. External links are working fine with this piece of code shown in the link: http://www.demiseonline.com/misc/Iframeoverlay.html Now using this overlay - I wanted to open the twitter dialog which asks users to Allow access to their account. So in the code below, I replaced http://www.google.com with https://twitter.com/oauth/authenticate?oauth_token=VPVRIsnRz9IX4CAab7brert3jHiEs <div class="apple_overlay black" id="Overlay1" <iframe src ="http://www.google.com" width="100%" height="595px" frameborder="0" </iframe </div When I replace the code, as soon as I load the page, even before I click on the link to open the overlay - the page gets redirected to the twitter URL. Any idea why that happens for this URL. Thanks

  • manyToManyField question

    - by dotty
    Hay guys, I'm writing a simple app which logs recipes. I'm working out my models and have stumbled across a problem My Dish models needs to have many Ingredients. This is no problem because i would do something like this ingredients = models.ManyToManyfield(Ingredient) No problems, my dish now can have many ingrendients. However, the problem is that the ingredient needs to come in different quantities. I.E 4 eggs, 7 tablespoons sugar My Ingredient Model is very simple at the moment class Ingredient(models.Model): name = models.TextField(blank=False) slug = models.SlugField(blank=True) How would i go about work out this problem? What fields would i need to add, would i need to use a 'through' attribute on my ManyToManyfield to solve this problem?
