  • How can I keep data that a user has entered in my jQuery/Ajax pop-up form?

    - by Lucas McCoy
    I have a form on a website I'm working (you can see it here) on that allows my users to give feedback. It's an jQuery/Ajax popup form: $('.contact_us').click(function(){ var boxy_content; boxy_content += "<div style=\"width:300px; height:300px \"><form id=\"feedbacked\">"; boxy_content += "<p>Subject<br /><input type=\"text\" name=\"subject\" id=\"subject\" size=\"33\" /></p><p>Your E-Mail Address:<br /><input type=\"text\" name=\"your_email\" size=\"33\" /></p><p>Comment:<br /><textarea name=\"comment\" id=\"comment\" cols=\"33\" rows=\"5\"></textarea></p><br /><input type=\"submit\" name=\"submit\" value=\"Send >>\" />"; boxy_content += "</form></div>"; // Other code here... Is there anyway I can save what the user has entered (in case they see our error message when they try to submit)?

  • javascript: how to delay submitting data when several checkboxes clicked in short time interval?

    - by ~knb
    I have an array of checkboxes in a complex dynamic-html form. Whenever a user clicks one checkbox, a fairly expensive query is generated and submitted to a remote server. I want to delay this submit action depending on the users next action. If the user clicks several checkboxes quickly, all of the first clicks should be discarded, only the last one is processed and eventually submitted after 1 second or so. maybe this is a common problem but I have never worked with timeouts before.

  • How Serializable works with insert in SQL Server 2005

    - by Spence
    G'day I think I have a misunderstanding of serializable. I have two tables (data, transaction) which I insert information into in a serializable transaction (either they are both in, or both out, but not in limbo). SET TRANSACTION ISOLATION LEVEL SERIALIZABLE BEGIN TRANSACTION INSERT INTO dbo.data (ID, data) VALUES (@Id, data) INSERT INTO dbo.transactions(ID, info) VALUES (@ID, @info) COMMIT TRANSACTION I have a reconcile query which checks the data table for entries where there is no transaction at read committed isolation level. INSERT INTO reconciles (ReconcileID, DataID) SELECT Reconcile = @ReconcileID, ID FROM Data WHERE NOT EXISTS (SELECT 1 FROM TRANSACTIONS WHERE data.id = transactions.id) Note that the ID is actually a composite (2 column) key, so I can't use a NOT IN operator My understanding was that the second query would exclude any values written into data without their transaction as this insert was happening at serializable and the read was occurring at read committed. I have evidence that reconcile is picking up entries

  • How can I handle multiple views of a data object? Which design pattern is acceptable?

    - by tranquil.byte
    I have a person object. class Person { private $name; ... } I need to be able to change how they are displayed on the front-end ( visitors have control ). They can choose list view, grid view, photo view for example. class PersonDisplay { public function displayList() { // Query database // Output html to display in list mode } public function displayPhoto() { // Query database // Output html to display in photo mode } } Is this an acceptable way to handle the presentation of the items on the front-end or is there a specific design pattern I should be researching to help me with this task? Does anyone have any suggestions or ideas where this could go wrong or if this could potentially make maintenance a nightmare? The Person object was just an example very similiar to what I am using.

  • WCF REST Does Not Contain All of the Relative File Path

    - by Brandon
    I have a RESTful WCF 3.5 endpoint as such: System.Security.User.svc This is supposed to represent the namespace of the User class and is desired behavior by our client. I have another endpoint I created for testing called: Echo.svc I am writing an overridden IHttpModule and in my module, I follow what almost everyone does by doing: string path = HttpContext.Current.Request.AppRelativeCurrentExecutionFilePath; If I make a call to: http://localhost/services/Echo/test My path variable has a value of '~/echo/test' However, when I make a call to: http://localhost/services/System.Security.User/test My path variable has a value of '~/system.security.user' In my 2nd situation, it is stripping off the '/test' on the end of any endpoint that contains multiple periods. This is undesired behavior and the only solution I have found to fixing this is some ugly string manipulation using the property which does contain the complete URL path: string rawPath = HttpContext.Current.Request.RawUrl; This returns '/services/system.security.user/test'. Does anyone know why my first situation does not return the rest of the URL path for endpoints that contain multiple periods in the name?

  • How do I get all data from a mysql table via php, and print out the contents of every cell ?

    - by roberto
    Hi. I've got a database table with at least three rows in it. From php, I have successfully connected to my db and extracted all table information with 'SELECT * from mytable' . Now I want to loop through first each row, and then each cell, printing out the contents of each cell. I know this might be a simple task for a more experienced programmer, but I can't figure it out, and I can't find any examples online and it's driving me stark raving bonkers. How can I do this ?

  • How to remove EXIF data without recompressing the JPEG?

    - by Denilson Sá
    I want to remove the EXIF information (including thumbnail, metadata, camera info... everything!) from JPEG files, but I don't want to recompress it, as recompressing the JPEG will degrade the quality, as well as usually increasing the file size. I'm looking for a Unix/Linux solution, even better if using the command-line. If possible, using ImageMagick (convert tool). If that's not possible, a small Python, Perl, PHP (or other common language on Linux) script would be ok. There is a similar question, but related to .net.

  • Split a table in Word without losing row title

    - by Shane Hsu
    Word has the feature to repeat title row of a table when a table is so long that it spans a bunch of pages. I need to categorize my data into several pages, and I did that by splitting the table and insert page split to put them all in a page of itself. So now I got several page of data, but only the first page has title row. Is there anyway else to do this beside manually adding the title row to all the other pages? Original data: _________________ | Cat. Data | | 1 * | | 1 * | | 1 * | | 1 * | | 1 * | | 1 * | | 2 * | | 2 * | | 2 * | | 2 * | | 3 * | |___3______*______| And then turn it into: _________________ | Cat. Data | | 1 * | | 1 * | | 1 * | | 1 * | | 1 * | |___1______*______| Next page _________________ | Cat. Data | | 2 * | | 2 * | | 2 * | |___2______*______| Next Page _________________ | Cat. Data | | 3 * | |___3______*______|

  • Parse filename, insert to SQL

    - by jakesankey
    Thanks to Code Poet, I am now working off of this code to parse all .txt files in a directory and store them in a database. I need a bit more help though... The file names are R303717COMP_148A2075_20100520.txt (the middle section is unique per file). I would like to add something to code so that it can parse out the R303717COMP and put that in the left column of the database such as: (this is not the only R number we have) R303717COMP data data data R303717COMP data data data R303717COMP data data data etc Lastly, I would like to have it store each full file name into another table that gets checked so that it doesn't get processed twice.. Any Help is appreciated. using System; using System.Data; using System.Data.SQLite; using System.IO; namespace CSVImport { internal class Program { private static void Main(string[] args) { using (SQLiteConnection con = new SQLiteConnection("data source=data.db3")) { if (!File.Exists("data.db3")) { con.Open(); using (SQLiteCommand cmd = con.CreateCommand()) { cmd.CommandText = @" CREATE TABLE [Import] ( [RowId] integer PRIMARY KEY AUTOINCREMENT NOT NULL, [FeatType] varchar, [FeatName] varchar, [Value] varchar, [Actual] decimal, [Nominal] decimal, [Dev] decimal, [TolMin] decimal, [TolPlus] decimal, [OutOfTol] decimal, [Comment] nvarchar);"; cmd.ExecuteNonQuery(); } con.Close(); } con.Open(); using (SQLiteCommand insertCommand = con.CreateCommand()) { insertCommand.CommandText = @" INSERT INTO Import (FeatType, FeatName, Value, Actual, Nominal, Dev, TolMin, TolPlus, OutOfTol, Comment) VALUES (@FeatType, @FeatName, @Value, @Actual, @Nominal, @Dev, @TolMin, @TolPlus, @OutOfTol, @Comment);"; insertCommand.Parameters.Add(new SQLiteParameter("@FeatType", DbType.String)); insertCommand.Parameters.Add(new SQLiteParameter("@FeatName", DbType.String)); insertCommand.Parameters.Add(new SQLiteParameter("@Value", DbType.String)); insertCommand.Parameters.Add(new SQLiteParameter("@Actual", DbType.Decimal)); insertCommand.Parameters.Add(new SQLiteParameter("@Nominal", DbType.Decimal)); insertCommand.Parameters.Add(new SQLiteParameter("@Dev", DbType.Decimal)); insertCommand.Parameters.Add(new SQLiteParameter("@TolMin", DbType.Decimal)); insertCommand.Parameters.Add(new SQLiteParameter("@TolPlus", DbType.Decimal)); insertCommand.Parameters.Add(new SQLiteParameter("@OutOfTol", DbType.Decimal)); insertCommand.Parameters.Add(new SQLiteParameter("@Comment", DbType.String)); string[] files = Directory.GetFiles(Environment.CurrentDirectory, "TextFile*.*"); foreach (string file in files) { string[] lines = File.ReadAllLines(file); bool parse = false; foreach (string tmpLine in lines) { string line = tmpLine.Trim(); if (!parse && line.StartsWith("Feat.

  • Fluent NHibernate beginner problem: How to convert single column data to custom class?

    - by Stefan Ahlm
    I am very new to Fluent NHibernate and I have a problem that I cant find the answer to. I have a string column in my database table, containing a mathematical expression i.e: "10 + 15 * 5". On my entity I have a property that I call Formula and this returns a class that contains the mathematical "formula" (not as a string). I beleive this post http://intellect.dk/post/Implementing-custom-types-in-nHibernate.aspx explains how to solve it for NHibernate. But I am not sure... How do I get this working with Fluent NHibernate?

  • Tomcat 6 Realm Config with Windows AD

    - by mat
    We have Tomcat 6 connecting to a Win2k3 Server running AD. The realm is configured as such <Realm className="org.apache.catalina.realm.JNDIRealm" debug="99" referrals="follow" connectionURL="<url>" connectionName="CN=Query Account,OU=Service Accounts,DC=company,DC=com" connectionPassword="<pwd>" userBase="OU=Users,DC=company,DC=com" userSubtree="true" userSearch="(sAMAccountName={0})" userRoleName="member" roleBase="OU=Security Groups,DC=company,DC=com" roleName="cn" roleSearch="(member={0})" roleSubtree="true"/> Our groups in AD are such Security Groups (OU) IT (OU) IT Support (OU) Support Staff (CN) The LDAP security works if in the web.xml, I speficy Support Staff. i.e works for Common names. We want ANY user under Security Groups OU to have access to the application and not just the CN. Tomcat does not search OU's and it just searches CN's in our case. How do we configure our settings so we can do OU level authorization and not just CN level ? thanks Mat

  • Need a good way to store data in a DB from a table on a webpage that can have N columns.

    - by Abe Miessler
    Users need to be able to add a specific type of column to an otherwise static table on my web page and then save the information they enter in there to the database. I've been told that in reality they will almost never go over 5 columns but I would rather support N. The columns will all be of the same datatype. My first thought was to have an XML column with the values from all added columns in there but I was curious if anyone else had come up with a better solution. Suggestions?

  • Any strategies for assessing the trade-off between CPU loss and memory gain from compression of data

    - by indiehacker
    Are very large TextProperties a burden? Should they be compressed? Say I have a information stored in 2 attributes of type TextProperty in my datastore entities. The strings are always the same length of 65,000 characters and have lots of repeating integers, a sample appearing as follows: entity.pixel_idx = 0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,1,1,1,1,5,5,5,5,5,5,5,5,5,5,5,5....etc. entity.pixel_color = 2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,1,1,1,1,1,1,1,1,1,1,1,1,...etc. So these above could also be represented using much less storage memory by compressing say using only each integer and the length of its series ( '0,8' for '0,0,0,0,0,0,0,0') but then its takes time and CPU to compress and decompress? Any general ideas? Are there some tricks for testing different attempts to the problem?

  • Can't echo jquery (with ajax) variable in php

    - by Lars Kerff
    I'm trying to post a variable through ajax. But it won't echo the variable in php. This are the variables (these are working, seen in the log): $("#slider").bind("valuesChanged", function(e, data){console.log("min: " + data.values.min + " max: " + data.values.max);}); The Ajax part: $("#slider").bind("valuesChanged", function (e, data) { $.ajax({ type: "POST", dataType: "text", url: "../test.php", data: { minValue: data.values.min, maxValue: data.values.max }, async: false, success: function(data){ alert('yeah') }, error: function(xhr) { alert('fail') // if your PHP script return an erroneous header, you'll land here } }); }); </script> And php echo: <?php if ( $_POST ) { echo $_POST[ 'minValue' ]; } ?> Now why does it not echo the post? Thanks!
