  • Reporting. MS Word templates population required

    - by Andrew Florko
    Application we developed fills MS Word templates with data from Database. Customers require to have ability edit Word templates via MS Word (change style, font, layout e.t.c) with no additional software to be installed and no training. AFAIK, Sql Reporting Services and Crystal Reports can't populate MS Word templates produced in MS Word. So we implemented our custom solution that maps .net classes onto xml-saved MS Word documents. It looks like we declare class MyTemplate { // maps to [age] field declared in ms document straight in the text int Age { get; set; } // maps to table by attributes applied to property (omitted) List<Person> Persons { get; set; } } We also implemented images insertion. Are there any free libraries for this task or may be you use your own MS-word templators in your projects?

  • Anonymous users support vs Google bot

    - by Andy
    I have a User class in my web app that represents a user currently logged in. Every time a user vists a page, a User instance is populated based on authentication data supplied in cookies. A User instance is created even if an anonymous user logs in - and a corresponding new record is created in the User table in the database. This approach allows me to save some state info for the current user regardless of its type. The problem however with this approach is the Google bot, and other non-human web organisms crawling my pages. Every time a bot starts to walk around the site, thousands of useless records will be created in the database, each of them only to be used for a single page. Question: what is the best trade off? How to support anonymous users, save their state, and don't get too much overhead because of cookieless bots?

  • How to find the right object in a Rails controller based on two variables?

    - by sscirrus
    Hi everyone, I have a three-table system: Companies, Customers, and Matches. The matches include, for example, private notes that each party makes about the other and some options they can set regarding the other. I have two sets of views centered around Companies and Customers for each party to look at the other and modify their notes and settings. # Customers Controller def show @customer = Customer.find(params[:customer]) @matchings = @candidate.matchings.find... @company = Company.find(params[:company]) end Obviously the @matchings is incomplete. Given that @matchings has fields customer_id and company_id, how do I find the right matching record? Thank you!

  • Is this possible with Sql 2005 CTE?

    - by aenima1982
    I have been working on a query that will return a suggested start date for a manufacturing line based on due date and the number of minutes needed to complete the task. There is a calendar table(LINE_ID, CALENDAR_DATE, SCHEDULED_MINUTES) that displays per manufacturing line, the number of minutes scheduled for that day. Example: (Usually 3 shifts worth of time scheduled per day, no weekends but can vary) 1, 06/8/2010 00:00:00.000, 1440 1, 06/7/2010 00:00:00.000, 1440 1, 06/6/2010 00:00:00.000, 0 1, 06/5/2010 00:00:00.000, 0 1, 06/4/2010 00:00:00.000, 1440 In order to get the suggested start date, I need to start with the due date and iterate downward through the days until i have accumulated enough time to complete the task. My Question can something like this be done with CTE, or is this something that should be handled by a cursor. Or... am i just going about this the wrong way completely??

  • Help me write a nicer SQL query in Rails

    - by Sainath Mallidi
    Hi, I am trying to write an SQL query to update some of the attributes that are regularly pulled from source. the output will be a text file with the following fields: author, title, date, popularity I have two tables to update one is the author information and the other is popularity table. And the Author Active Record object has one popularity. Currently I'm doing it like this.\ arr.each { |x| x = x.split(" ") results = Author.find_by_sql("SELECT authors.id FROM authors, priorities WHERE authors.id=popularity.authors_id AND authors.author = x[0]") results[0].popularity.update_attribute("popularity", x[3]) I need two tables because the popularity keeps changing, and I need only the top 1000 popular ones, but I still need to keep the previously popular ones also. Is there any nicer way to do this, instead of one query for every new object. Thanks.

  • How to repopulate DataTables when having lots of data?

    - by chobo2
    Hi I am using datatables jquery plugin. I now have to clear the entire datatable and populate it with new data on the fly(all done through ajax). So what I was thinking to do is when I need to do this. Destroy the datatable remove the data html call up the partial view that renders the table Rebind the datatable with jquery. However it seems that datatable has no destroy method. So I know you can set the datatable to do something with ajax but I am not sure how. My datatable just uses the dom way when the page is loaded. I don't want to use the "fnAddData" as I am not sure how to format this 2d array they want and I don't think this is the best option. I think the best option is some how render the partial view back and use there ajax plugin. But I am not sure where that is or how to use it(I know it exists but that's about it). Thanks

  • Should I use DATE and TIME as fields rather than DATETIME

    - by whitstone86
    I have a project on going for a TV guide, called mytvguide in the database - I use PHPMyAdmin. This is the structure for one table, which is called tvshow1: Field Type channel varchar(255) date date No airdate time No expiration time No episode varchar(255) setreminder varchar(255) but am not sure how to get DATE, TIME to work with the pagination script (below is the script, which works for the version with DATETIME): http://pastebin.com/6S1ejAFJ However, although the DATETIME one works - it shows programmes that air on the day itself like this: Programme 1 showing on Channel 1 2:35pm "Episode 2" Set Reminder Programme 1 showing on Channel 1 May 26th - 12:50pm "Episode 3" Set Reminder Programme 1 showing on Channel 1 May 26th - 5:55pm "Episode 3" Set Reminder but I'm not quite sure how to replicate that for the fields that use DATE, TIME functions as seen above. Any advice on this is appreciated, thanks!

  • Export MySQL Data as Insert Statements

    - by gav
    Hi All, I'm working in Ubuntu with MySql and I also have Query Browser and Administrator installed, I'm not afraid of the command line either if it helps. I want simply to be able to run a query and see a result set but then convert that result set into a series of commands that could be used to create the same rows in a table of an identical schema. I hope the question makes sense, it's quite a simple problem and one that must have been solved but I can't for the life of me work out where this kind of conversion is made available. Thanks in advance, Gav

  • [struts 2] How do you iterate through a list of objects?

    - by Kevin
    I have a User class that has a String username in it. I have a list of users that I'm trying to display in a table using <s:iterator value="users" id="list"> <tr> <td><s:property value="#list.username" /></td> <td></td> <td></td> <td></td> </tr> </s:iterator> The rows are being displayed the right number of times, so it's iterating through my list properly. However, I don't know how to access the username property to display it. Obviously what I have above isn't correct... Any ideas?

  • How to get the records using order by and so on

    - by paulrajj
    I have a table categories containing categories id having the records of 1 to 20. when i am doing the search query by using the IN function in mysql i got the results. but i am struggling to get the results using order by. The limit may be vary for every search as this is one of the input value. For example I have tried this query to find out the search results, select * from categories where category in (20,16,12,8) order by rand(), id limit 0,6 this query is executed and the results are in random category_id. the results will be, 8 12 16 20 and following this, another two records must be 8 12 If category_id contains only one record for 8 then, it should follow from 12,16. How can i achieve this ? thanks in advance.

  • optimized grid for rectangular items

    - by peterchen
    I have N rectangular items with an aspect ratio Aitem (X:Y). I have a rectangular display area with an aspect ratio Aview The items should be arranged in a table-like layout (i.e. r rows, c columns). what is the ideal grid rows x columns, so that individual items are largest? (rows * colums = N, of course - i.e. there may be "unused" grid places). A simple algorithm could iterate over rows = 1..N, calculate the required number of columns, and keep the row/column pair with the largest items. I wonder if there's a non-iterative algorithm, though (e.g. for Aitem = Aview = 1, rows / cols can be approximated by sqrt(N)).

I am trying to write a query that will allow me to get all records that have a name. Records that do not have a name have a FullName value of either null or an empty string. How do I get all of the Person records have a FullName? In other words, I want to ignore the records that do not have a FullName. Currently I am trying the following: SELECT * FROM Person p WHERE p.FullName IS NOT NULL AND LEN(p.FullName) > 0 Thank you

  • Update query for Access Database for certain Parameters

    - by nitinkhanna
    Hi, I am using MS Access as a database and using c#, .net for updating some records in it. But it is giving error saying "No value given for one or more required parameters." There are 5 colums in Table and I want to update only 2, for that I have written the query like "update User_DTL set user_role_id = '" + _UserRole + "', auth_id ='" + _authId + "'" + " WHERE Id = '" + _Id + "' "; where _UserRole, _authId, _Id are strings. What may be the error. Do I need to give every parameter in update statement or there is some other way. Thanks

  • How to get ListView to grow to the size of content

    - by Jared
    So I have a fairly complex activity the parent being a linearlayout with a table with some basic info and buttons. Then a couple listviews that the user can add items to. So these listviews grow more and more as the user uses the app. The problem I'm running into is the Linearlayout is bigger then the resolution of the screen and so it needs to scroll. So the scrolling doesn't work on the Listviews. I've tried playing with changing the layout_height of the listview and its child element with no success. Is there a way to make these couple listviews expand out to the amount of children? Or am I going about this all wrong? If so what other controls can I use? I'm open to any ideas. I really just don't know how to go about this. Thanks

  • Amazon EC2 multiple servers share session state

    Hi everyone, I have a bunch of EC2 servers that are load balanced. Some of the servers are not sharing session, and users keep getting logged in and out. How can I make all the server share the one session, possibly even using a partitionresolver solution public class PartitionResolver : System.Web.IPartitionResolver { private String[] partitions; public void Initialize() { // create the partition connection string table // web1, web2 partitions = new String[] { "192.168.1.1" }; } public String ResolvePartition(Object key) { String oHost = System.Web.HttpContext.Current.Request.Url.Host.ToLower().Trim(); if (oHost.StartsWith("10.0.0") || oHost.Equals("localhost")) return "tcpip=127.0.0.1:42424"; String sid = (String)key; // hash the incoming session ID into // one of the available partitions Int32 partitionID = Math.Abs(sid.GetHashCode()) % partitions.Length; return ("tcpip=" + partitions[partitionID] + ":42424"); } } -theo

  • HTML input text box vs CakePHP Automagic Form Elements

    Hi all, I was manually creating a simple form with one input text box field like this: <form action="/user/add" method="post"> <input type="text" name="data[user_id]" value="1"> But when I call $this->model->save($this->data) in the Controller, nothing was saved to the Table. Only when I used this and the data in the field was written to the database successfully: $form->create(null, array('url' => '/user/add')); echo $form->input('user_id', array('label' => 'User ID', 'value' => '1'));

  • Alternatives libraries for loading PNG images

    - by Robert
    My java J2SE application is reading a lot of (png) images from the web and some of them use features such as a transparency color for true-color images (tRNS section) that Sun's/Oracle's PNGImageReader implementation simply ignores. Therefore the common solution for loading via ImageIO.read(...); does not work for me as it relies on this incomplete PNGImageReader implementation. Does anybody know a png reader implementation that can read all forms of PNG images correctly - those with color table or true-color and alpha transparency or transparent color? As it is for a GPL project it should be a non-commercial one that can be included without licensing problems into the app. Edit: My be this question was too specific. Therefore let be redesign my question: Who knows alternative implementations and libraries that are able to load PNG files? I will then test the implementations for their capabilities to load some test png images. Edit2: The end result have to be a BufferedImage

  • Appropriate data structure for a buffer of the packets

    - by psihodelia
    How to implement a buffer of the packets where each packet is of the form: typedef struct{ int32 IP; //4-byte IP-address int16 ID; //unique sequence id }t_Packet; What should be the most appropriate data structure which: (1) allows to collect at least 8000 such packets (fast Insert and Delete operations) (2) allows very fast filtering using IP address, so that only packets with given IP will be selected (3) allows very fast find operation using ID as a key (4) allows very fast (2), then (3) within filtered results ? RAM size does matter, e.g. no huge lookup table is possible to use.

  • jQuery UI Draggable 'stop' event called too many times?

    - by Graham
    I have a feeling I'm either misunderstanding the 'stop' event or not doing it right, but it seems to be called several times while the element is bound to is being dragged. makeAllDragable = function () { $(".test-table").draggable({ start: function (event, ui) { $(this).click(); }, stop: function (event, ui) { foo() } }).click(function () { selectTable($(this)); }); } foo = function () { alert("test"); } In this example foo is called about 30 times, shouldn't is just be when I release the draggable? The jQuery docs don't actually say one where or another though.

  • Catch Id (INT AUTO INCREMENT) of a Record after INSERT INTO Statement

    - by Johannes
    This is my first time I use MySQL as datastorage for my C# Application, as I've seen that there is no UNIQUEIDENTIFIER type as in SQL server I decieded to use INT with AUTO_INCREMENT, my problem is now if I execute a INSERT, how may I get the ID of the Record I just added. My quick and dirty solution has been to execute a SELECT MAX(ID) FROM table Statement. But this doesn't seem consistent. I belive there is a better solution something like mysql_insert_id() (PHP). Any Idea how to resolve this in C#?
