  • How can I explain to a programmer that CSS positioning has many benefits over table based layouts?

    - by Pat
    I have a friend who wishes to work as a freelance web developer, but insists that tables are the way forwards for layouts. Several points he maintains in favour of tables: 1 This is what was taught at the beginning of 10 years of programming & computer science degrees. 2 Large companies use tables to achieve 'technical' things. 3 It saves time I have coded him some examples of CSS exactly matching table based layouts, and provided many links to articles explaining SEO and accessibility benefits. From the perspective of a client, I have been explaining to him that I wouldn't hire someone using outdated methods as their main strategy for layout. As he is my friend and I wish him every success, I believe it is important for him to gain the best start when pitching for work. The question again: How can I explain to a programmer that CSS positioning has many benefits over table based layouts?

  • I've created a database table using Visual Studio for my C# program. Now what?

    - by Kevin
    Hi! I'm very new to C#, so please forgive me if I've overlooked something here. I've created a database using Visual Studio (add new item service-based database) called LoadForecast.mdf. I then created a table called ForecastsDB and added some fields. My main question is this: I've created a console application with the intention of writing some data to the newly created database. I've added LoadForecast.mdf as a data source for my program, but is there anything else I should do? I saw an example where the next step was adding a "data diagram", but this was for a visual application, not a console application. Do I still need to diagram the database for my console app? I just want to be able to write new records out to my database table and wasn't sure if there were any other things I needed to do for the VS environment to be "aware" of my database. Thanks for any advise!

  • SQL update fields of one table from fields of another one.

    - by Nir
    I'm having two tables: A [ID, column1, column2, column3] B [ID, column1, column2, column3, column4] A table will always be subset of B table (meaning all columns of A are also in B). I want to update a record with a specific ID in B with their data from A for all columns of A. This ID exists both in A and B. Is there an UPDATE syntax or any other way to do that without specifying the column names, just saying "set all columns of A"? I'm using postgresql, so a specific non-standard command is also accepted (however, not preferred). Thanks.

  • How to make a table view which can be scrolled for ever?

    - by mystify
    I have a set of 100 rows, pretty similar to values which can be selected in a picker. When the user scrolls the table, I want the rows to be appended like an forever-ongoing assembly-belt. So when the user scrolls down and reaches the row 100, and scrolls even further, the table view will show again row 1, and so on. Reverse direction same thing. My thoughts: don't display scroll indicators (they would make not much sense, probably) what value to return in the numberOfRows delegate method? This infinity constant? in cellForRowAtIndexPath: simply wrap the index around when it exceeds bounds?

  • Fluent nHibernate - How to map a non-key column on an association table?

    - by The Matt
    Taking an example that is provided on the Fluent nHibernate website, I need to extend it slightly: I need to add a 'Quantity' column to the StoreProduct table. How would I map this using nHibernate? An example mapping is provided for the given scenario above, but I'm not sure how I would get the Quantity column to map: public class StoreMap : ClassMap<Store> { public StoreMap() { Id(x => x.Id); Map(x => x.Name); HasMany(x => x.Employee) .Inverse() .Cascade.All(); HasManyToMany(x => x.Products) .Cascade.All() .Table("StoreProduct"); } }

  • Is there any Inheritance problem with <table> and it's elements, like <form> elements?

    - by metal-gear-solid
    Is there any Inheritance problem with <table>, tr th td tbody thead tfoot also like form elements? In IE 6+ and FF 3+ with Strict doctype. Tables also have inheritance turned off in some browsers. You may notice that in some browsers, your tables’ text will be larger, clunkier and not so pretty. This is also due to inheritance. Many browsers give tables their own style. It's mentioned here http://www.komodomedia.com/blog/2006/10/css-trickery-part-5-inheritance/ For which browsers author is talking about, it's not mentioned I tested on FF 3.6 and IE7 but unable to find is there any issue. I just wanted to be sure before adding this in my CSS reset. Do i really need this? table { font-family:inherit; font-size:inherit; font-weight:inherit; }

  • which is better, creating a materialized view or a new table?

    - by Carson
    I have some demanding mysql queries that are needed to grap same up-to-date datasets from 5-7 mysql tables. I am thinking of creating a table or materialized view to gather all demanding columns from other tables, so as to increase performance. If I create that table, I may need to do extra insert / update / delete operation each time other tables updated. if I create materialized view, I am worrying if the performance can be greatly improved. Because data from other tables are changing very frequently. Most likely, the view may need to be created first everytime before selecting it. Any ideas? e.g. how to cache? other extra measures I can do?

  • How to access data using VBSCRIPT from a stored procedure which contains values in Temp table ?

    - by Srivigneshwar
    Hi , for testing purpose I wrote a VBscript which will fetch values from Sybase by executing a stored procedure which contains values in temp table. When I run the script I get the following errors , "Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record." or "Item cannot be found in the collection corresponding to the requested name or ordinal." Somewhere when I was googling I found that , the above error message will be shown when we use temp table in stored procedure, if that is the reason , then how can I access data via VBscript by executing the stored procedure ??

  • 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 notify table-data change to a client program?

    - by JMSA
    Suppose I have an application that access data resident in a central DB server and more than one user access data from client machines networked with the DB server. Suppose two client machines are running a copy of the application and two users are accessing the same DB table. How can I automatically refresh the data on the GUI, that is being viewed by one client, as soon as a change is made by another client in the DB table-data? Which technology should be used to solve this particular scenario in .net? WCF?

  • Rails 2.3.5 table populated by fixtures at end of test run rather than at start

    - by rlandster
    I start with a test database containing the schema but with no data in the tables. I run a test like so cd test/ ruby unit/directive_test.rb I get failures indicating that the code found no data in the data tables. However, I look at the tables after running that test and the data is now in the the table. In fact, if I immediately run the test again I get no failures. So it appears that the fixture is being loaded into the table too late for one of my modules to find it. When are the fixtures loaded? After or before the app/model/*.rb files are executed? If it is after the models are executed is there a way to delay the loading? This issue is also relevant when running rake test:units since that task clears the test data after it finished.

  • How do I UPDATE a Linked Server table where "alias" is required, in SQL Server 2000?

    - by Mark Hurd
    In SQL Server 2005 tablename can be used to distinguish which table you're referring to: UPDATE LinkedServer.database.user.tablename SET val=u.val FROM localtable u WHERE tablename.ID=u.ID In SQL Server 2000 this results in Server: Msg 107, Level 16, State 2 The column prefix 'tablename' does not match with a table name or alias name used in the query. Trying UPDATE LinkedServer.database.user.tablename SET val=u.val FROM localtable u WHERE LinkedServer.database.user.tablename.ID=u.ID results in Server: Msg 117, Level 15, State 2 The number name 'LinkedServer.database.user.tablename' contains more than the maximum number of prefixes. The maximum is 3. And, of course, UPDATE LinkedServer.database.user.tablename SET val=u.val FROM localtable u WHERE ID=u.ID results in Server: Msg 209, Level 16, State 1 Ambiguous column name 'ID'. (In fact searching on "The number name contains more than the maximum number of prefixes. The maximum is 3." I found the answer, but I've typed up this question and I'm going to post it! :-) )

Here is the code: thestring = (raw_input()) sentence = thestring.split(" ") sentence.sort() count = {} for word in thestring.split(): try: count[word] += 1 except KeyError: count[word] = 1 print sentence print count And when I run the code I get this: ['apple', 'apple', 'banana', 'mango', 'orange', 'pear', 'pear', 'strawberry'] {'apple': 2, 'pear': 2, 'strawberry': 1, 'mango': 1, 'orange': 1, 'banana': 1} However, ideally I want it printed in a table that looks something like: apple.....|.....2 banana....|.....1 mango.....|.....1 orange....|.....1 pear......|.....2 strawberry|.....1 Thanks for any help!

  • How to get some randomized concats based on 2 columns from 1 table?

    - by Nils Riedemann
    Hey folks, i have a large user Database (13k+), and for some reason i need to create random names. The users table has "first_name" and "last_name". Now i want to have 10 concats of full_name and last_name of two completely random rows. Is that even possible with SQL? My other idea was just to create a full_names and last_names table … but that would'nt be as much challenging. Oh, and it should not take up too much performance :) (so order by rand() is not an option ;))

  • Can't create a MySQL query that generates 4 rows for each row in the table it references.

    - by UkraineTrain
    I need to create a MySQL query that generates 4 rows for each row in the table it references. I need some of the information in those rows to repeat and some to be different. In the table each row stands for one day. I need to break the day up in 6 hour increments, hence the four rows for each entry. I need to create one column which for each day will have '12AM', '6AM', '12PM', and '6PM' values and another column will have the corresponding numeric values calculated for those entries. Thanks a lot in advance and I will really appreciate any help on this.
