  • Ajax.BeginForm is submitting disabled form elements

    - by Fiffe
    Using MVC3 and Ajax.BeginForm I surprisingly discovered that mvc ajax forms submits elements with the attribute disabled="disabled". I have tested both select and text inputs. I was suprised because they should not be submited and they will not when using Html.BeginForm. Is there some hidden option or a workaround for this? [EDIT example] @using (Ajax.BeginForm("Action", "Control", new AjaxOptions() { HttpMethod = "POST" })) { <input type="text" name="_enabled" value="_enabled" /> <input type="text" name="_disabled" value="_disabled" disabled="disabled" /> <input type="submit" value="POST" /> }

  • Java: matching two different type of array

    - by sling
    Hi, I am doing a password login that requires me to match two array: User and Pass. If user key in "mark" and "pass", it should show successfully. However I have trouble with the String[] input = pass.getPassword(); and the matching of the two arrays. String[] User = {"mark", "susan", "bobo"}; String[] Pass = {"pass", "word", "password"}; String[] input = pass.getPassword(); if(Pass.length == input.length && user.getText().equals(User)) { lblstat.setForeground(Color.GREEN); lblstat.setText("Successful"); } else { lblstat.setForeground(Color.RED); lblstat.setText("Failed"); }

  • Substring and its reverse in a string

    - by christa
    My professor was talking about this in a Dynamic programming class and asked us to think over it. She gave us some examples as well. Given a string, we were to find the longest continuous subsequence whose reverse is also a subsequence present in the given string. Example: INPUT: pqrstuvtsrv OUTPUT: i=3, k=2 rst -> tsr (rst found first at i=3 and for 2 more positions) INPUT: mpqrsrqp OUTPUT: i=2, k=6 pqrsrqp in reverse INPUT: mmpqssss OUTPUT: i=5, k=3 I thought of putting the string and its reverse into 2 different arrays and comparing character by character. But I'm sure this is not the best way to do it. Any suggestions as to what could be the most efficient ?

  • Checking for any lowercase letters in a string

    - by pcampbell
    Consider a JavaScript method that needs to check whether a given string is in all uppercase letters. The input strings are people's names. The current algorithm is to check for any lowercase letters. var check1 = "Jack Spratt"; var check2 = "BARBARA FOO-BAR"; var check3 = "JASON D'WIDGET"; var isUpper1 = HasLowercaseCharacters(check1); var isUpper2 = HasLowercaseCharacters(check2); var isUpper3 = HasLowercaseCharacters(check3); function HasLowercaseCharacters(string input) { //pattern for finding whether any lowercase alpha characters exist var allLowercase; return allLowercase.test(input); } Is a regex the best way to go here? What pattern would you use to determine whether a string has any lower case alpha characters?

  • Replace named group in regex

    - by Tomas Voracek
    I want to use regular expression same way as string.Format. I will explain I have: string pattern = "^(?<PREFIX>abc_)(?<ID>[0-9])+(?<POSTFIX>_def)$"; string input = "abc_123_def"; Regex regex = new Regex(pattern, RegexOptions.IgnoreCase); string replacement = "456"; Console.WriteLine(regex.Replace(input, string.Format("${{PREFIX}}{0}${{POSTFIX}}", replacement))); This works, but i must provide "input" to regex.Replace. I do not want that. I want to use pattern for matching but also for creating strings same way as with string format, replacing named group "ID" with value. Is that possible? I'm looking for something like: string pattern = "^(?<PREFIX>abc_)(?<ID>[0-9])+(?<POSTFIX>_def)$"; string result = ReplaceWithFormat(pattern, "ID", 999); Result will contain "abc_999_def". How to accomplish this?

  • php question regarding arrays

    - by Martin
    Hi there, I'm a (complete) php noob and need a little help with something. I'm working on a project whereby a user can select up to 6 categories via a form (I'm using ExpressionEngine). The output is like this: "Cat1","Cat2","Cat3" ...and so on. The user can select up to 6 categories on that form. What I need: even if my result is 3 categories I need to have 6 'cells' - for want of a better word - even if they're empty: "Cat1","Cat2","Cat3","","","" I've tried this: <?php $str = '(output goes here)'; print_r(explode(',', $str, 6)); ?> ...but the output give me: Array ( [0] => Cat1 [1] => Cat2 [2] => Cat3 [3] => [4] => [5] => ) How do I get from that to this: "Cat1","Cat2","Cat3","","","" Does this make sense? Thanks Martin

  • Regex Pattern for ignoring a custom escape character

    - by user1517464
    I am trying to find a suitable regex for matching pair of custom characters in an input string. These custom characters are replaced by their corresponding html tags. For e.g. The input string can have underscores in pairs to indicate words in bold. Hence, _Name_ outputs as <b>Name</b> However if there is a genuine underscore in the string, it cannot be replaced by "bold" tags and has to be ignored. The genuine underscore has to be preceded by / (I couldn't find a better character, it could be one more underscore or hyphen or whatever). Any single or paired occurrance of this genuine underscore has to be ignored by regex. So far I could come up with this regex: var pattern = @"(?!/)_(.*?)(?!/)_"; But it fails in below input string: _Tom_Katy/_Richard/_/_Stephan_and many users It outputs as <b>Tom</b>Katy/<b>Richard/_/</b>Stephan_and many users Many Thanks in Advance, Pr

  • Can the behaviour of new HTML5 form types be overridden?

    - by Mark Perkins
    I was wondering if anyone knew if it were possible to override the default behaviour of browsers that support the new HTML input types such as type="email" and type="date"? I appreciate that I could test if a browser supports an input type and provide a fallback for those browsers that don't, but what I want to know is is there any way to prevent that default behaviour from happening in browsers that do support it? For instance, if in Opera I want to use the date input type, but I don't want Opera to display the native datepicker (i.e. I want to replace it with my own custom one) is that possible? Are there any DOM events triggered like onDatePickerShow that one can hook into? I don't believe that this is possible, but if anyone knows for sure one way or the other I would love to hear from you.

  • To find first N prime numbers in python

    - by Rahul Tripathi
    Hi All, I am new to the programming world. I was just writing this code in python to generate N prime numbers. User should input the value for N which is the total number of prime numbers to print out. I have written this code but it doesn't throw the desired output. Instead it prints the prime numbers till the Nth number. For eg.: User enters the value of N = 7. Desired output: 2, 3, 5, 7, 11, 13, 19 Actual output: 2, 3, 5, 7 Kindly advise. i=1 x = int(input("Enter the number:")) for k in range (1, (x+1), 1): c=0 for j in range (1, (i+1), 1): a = i%j if (a==0): c = c+1 if (c==2): print (i) else: k = k-1 i=i+1

  • Help with linq to sql compiled query

    - by stackoverflowuser
    Hi I am trying to use compiled query for one of my linq to sql queries. This query contains 5 to 6 joins. I was able to create the compiled query but the issue I am facing is my query needs to check if the key is within a collection of keys passed as input. But compiled queries do not allow passing of collection (since collection can have varying number of items hence not allowed). For instance input to the function is a collection of keys. Say: List<Guid> InputKeys List<SomeClass> output = null; var compiledQuery = CompiledQueries.Compile<DataContext, IQueryable<SomeClass>>( (context) => from a in context.GetTable<A>() where InputKeys.Contains(a.Key) select a); using(var dataContext = new DataContext()) { output = compiledQuery(dataContext).ToList(); } return output; Is there any work around or better way to do the above?

    Hi I am looking at this tutorial and it confuses me as I don't get the SP CREATE PROCEDURE [dbo].[spTEST_InsertXMLTEST_TEST](@UpdatedProdData nText) AS DECLARE @hDoc int exec sp_xml_preparedocument @hDoc OUTPUT,@UpdatedProdData INSERT INTO TBL_TEST_TEST(NAME) SELECT XMLProdTable.NAME FROM OPENXML(@hDoc, 'ArrayOfTBL_TEST_TEST/TBL_TEST_TEST', 2) WITH ( ID Int, NAME varchar(100) ) XMLProdTable EXEC sp_xml_removedocument @hDoc First I am using SQL 2005 and do I need to install something on the server to get OPENXML to work? Next I don't get what these statements do // not sure what @hDoc is for and why it is an int DECLARE @hDoc int // don't get what this is and where the output is. exec sp_xml_preparedocument @hDoc OUTPUT,@UpdatedProdData // don't get why it is "XMLProdTable" and if it always has to be like this SELECT XMLProdTable.NAME // pretty muct don't get anything what is happening after OPENXML FROM OPENXML(@hDoc, 'ArrayOfTBL_TEST_TEST/TBL_TEST_TEST', 2) WITH ( ID Int, NAME varchar(100) ) XMLProdTable // Don't know what this is really executing EXEC sp_xml_removedocument @hDoc Thanks

  • Dynamic case statement in bash

    - by infra.user
    Hi folks, I'm trying to figure out how to create a dynamic case statement in a bash script. For example, let's say I have the output of an awk statement with the following contents red green blue In this scenario, the output can change at any time. I'm trying to then execute different logic if a value is included in this awk output. So if the data above is in $list, then I'd conceptually like to do something like: case "${my_var}" in $list) ..... something_else) ..... esac I'm trying to use this to build a dynamic custom tab completion function (see http://www.debian-administration.org/article/An_introduction_to_bash_completion_part_2 for some background). Any ideas? Thanks.

  • How to create a backpropagation neural network in neurondonet?

    - by Suraj Prakash
    I am doing stock market prediction using ANNs in c#.net. I am using NeuronDotNet for the neural part. I have to give eight inputs to the network, with a hidden layer consisting 8 nodes and a single node output layer. Can anybody please give me some coding ideas for this???? This project was not a AI course assignment, but my major project. I have studied about the stocks and found various factors that affected the future value of stock of a company. Now I have to use these factors as input to the neural network. I am not getting into how to implement these factors in the neural network. I have just decided to use those eight factors as eight nodes in the input layer but things are going complex. My concern is to use these factors as input and train the neural network for output as next day's stock value. What major things should I have to care about??

  • Dynamic page with JSF

    - by Milan
    Hello everybody! I need to make dynamic web-page/form in JSF. Dynamic: In runtime I get the number of input fields Ill have together with buttons. I'll try to demonstrate you what I need to make. inputField1 inputField2 inputField3 BUTTON1 inputField4 inputField5 BUTTON2 inputField6 inputFiled7 inputField8 inputField9 BUTTON3 I hope you understand me what I want to make. So I when I click on some of the buttons I have to collect the data from the input fields and do something with the data. If I click BUTTON1 I collect data from inputField1 inputField2 inputField3 BUTTON2 inputField4 inputField5, etc. Probably I should create the input fields programmatically and group them in forms. Any idea how to do it? Any idea?

  • Accessing and binding events to an ASP.NET Grid view using Jquery

    - by Sayem Ahmed
    I have an ASP page which displays a text box when it loads. It takes an input number, send it to the server through post back, and then displays some record in a grid view. After a number is input into the box, the server fetches some data from a database and add records to the grid view. It also contains a link column, whose URL is set to "#", so that the page isn't redirected when it is clicked. Now I want to bind a jquery "click" event to that link. How can I do that ? I have tried that to do myself but failed, because it is not available when the DOM is loaded (since it only contains rows when a number is input through the box), and is being modified through ASP.NET Ajax post back.

  • SAP Shortcut file - How to redirect to specific transaction screen in SAP?

    - by Kiru
    Problem : How to redirect the user to a specific executed transaction screen in SAP? Generated the SAP shortcut and able to redirect the user to specific transaction screen. It is also possible to prefill the required input parameters. The corresponding line in the shortcut is- Command=AB12 RIWO00-input1=200001212; where AB12 is the trasaction, and input1 is the input parameter. This will open that SAP screen, with AB12 transaction and the input parameter would be filled with values. But this mandates the user to clicks on enter explicitly/click on execute button explicitly after opening through the shortcut file. Is it possible to include that enter also in the shortcut file? Thank you :)

  • HTML Upload Form will only upload files found in the directory of the PHP file.

    - by vette982
    I have an image uploader that uses the imgur.com API and jQuery's .ajax() function to upload images to their servers. However, if I browse for an image using the <input type="file"/> element of the form, it will only be successful in uploading an image if the image file is found in the same directory as the page.php file that the form is found in (shown below). How can I allow the form to upload images from any directory on my computer? page.php: <form action="page.php" method="post"> <input type="file" name="doc" id="doc" /><br/> <input type="image" src="go.gif" name="submit" id="submit" /> </form>

  • OpenCV in Python can't scan through pixels

    - by Marco L.
    Hi everyone, I'm stuck with a problem of the python wrapper for OpenCv. I have this function that returns 1 if the number of black pixels is greater than treshold def checkBlackPixels( img, threshold ): width = img.width height = img.height nchannels = img.nChannels step = img.widthStep dimtot = width * height data = img.imageData black = 0 for i in range( 0, height ): for j in range( 0, width ): r = data[i*step + j*nchannels + 0] g = data[i*step + j*nchannels + 1] b = data[i*step + j*nchannels + 2] if r == 0 and g == 0 and b == 0: black = black + 1 if black >= threshold * dimtot: return 1 else: return 0 The loop (scan each pixel of a given image) works good when the input is an RGB image...but if the input is a single channel image I get this error: for j in range( width ): TypeError: Nested sequences should have 2 or 3 dimensions The input single channel image (called 'rg' in the next example) is taken from an RGB image called 'src' processed with cvSplit and then cvAbsDiff cvSplit( src, r, g, b, 'NULL' ) rg = cvCreateImage( cvGetSize(src), src.depth, 1 ) # R - G cvAbsDiff( r, g, rg ) I've also already noticed that the problem comes from the difference image got from cvSplit... Anyone can help me? Thank you
