  • html transparent background

    - by amarsh-anand
    I want to create a webpage with transparent background, a table and some text. I have seen posts related to this, but due to my lack of familiarity with css, I somehow cant get my code to work. I just want a transparent background, while this code is making everything transparent. Can someone kindly help. <html> <head><style type="text/css"> div.transbg {background-color:#4a6c9b; opacity:0.6;} </style></head> <div class="transbg"> <body><Center><font color="#FFFFFF"> <b>Toll Charges</b> <table bgcolor="#000000" cellspacing=3> <tr> <td bgcolor="#009900"><font color="#FFFFFF" align="left"> &nbsp; &nbsp;Class 2 inc Private&nbsp;</font></td> <td bgcolor="#009900"><font color="#FFFFFF" align="right"> &nbsp;A$ 4.95 &nbsp;</font></td> </tr> <tr> <td bgcolor="#009900"><font color="#FFFFFF" align="left"> &nbsp; &nbsp;Class 2 inc Commercial&nbsp;</font></td> <td bgcolor="#009900"><font color="#FFFFFF" align="right"> &nbsp;A$ 13.95 &nbsp;</font></td> </tr> </table> <br> Toll has to be paid within 48 hrs of passage, else an additional A$ 13.95 of administration charges would be added </font></Center> </div> </body> </html>

  • Array within Form collecting multiple values with the same name possible?

    - by JM4
    Good afternoon, I will first start with the goal I am trying to accomplish and then give a very basic sample of what I need to do. Goal Instead of collecting several variables and naming them with keys individually, I have decided to give in and use an array structure to handle all inputs of the same type and rules. Once I have the variables, I will validate against them and if 'ok' store them in a MySQL table. The table will hold consumer information and will need to store multiple rows of the same type of information. First Pass I will leave out the validation portion of this question because I feel I need to first understand the basics. <form action="?" method="POST" name="Form"> Member 1 First Name:<input type="text" name="MemberFirstName[]" /><br /> Member 1 Last Name: <input type="text" name="MemberLastName[]" /><br /> Member 1 Email: <input type="text" name="MemberEmail[]" /><br /> Member 2 First Name:<input type="text" name="MemberFirstName[]" /><br /> Member 2 Last Name: <input type="text" name="MemberLastName[]" /><br /> Member 2 Email: <input type="text" name="MemberEmail[]" /><br /> Member 3 First Name:<input type="text" name="MemberFirstName[]" /><br /> Member 3 Last Name: <input type="text" name="MemberLastName[]" /><br /> Member 3 Email: <input type="text" name="MemberEmail[]" /><br /> <input type="submit" name="submit" value="Continue" /> </form> I am hoping that each input given for First Name (a required field) will generate a unique key for that particular entry and not overwrite any data entered. Because I am carrying information from page to page (checkout form), I am turning the POST variables into SESSION variables then storing in a mysql database in the end. My hope is to have: <?php $conn = mysql_connect("localhost", "username", "password"); mysql_select_db("DBname",$conn); $sql = "INSERT INTO tablename VALUES ('$_SESSION[Member1FirstName]', '$_SESSION[Member1LastName]', '$_SESSION[Member1Email]', '$_SESSION[Member2FirstName]', '$_SESSION[Member2LastName]', '$_SESSION[Member2Email]', '$_SESSION[Member1FirstName]', '$_SESSION[Member3LastName]', '$_SESSION[Member3Email]')"; $result = mysql_query($sql, $conn) or die(mysql_error()); Header ("Location: completed.php"); ?> Where Member1, Member2, and Member3 values will appear on their own row within the table. I KNOW my code is wrong but I am giving a first shot at the overall business purpose I am trying to achieve and trying to learn how to code the right way. I am very, very new to programming so any 'baby advice' is greatly appreciated.

  • Import text file crunching library for Java/Groovy ?

    - by devdude
    In a lot of real life implementations of applications we face the requirement to import some kind of (text) files. Usually we would implement some (hardcoded?) logic to validate the file (eg. proper header, proper number of delimiters, proper date/time value,etc.). Eventually also need to check for the existence of related data in a table (eg. value of field 1 in text file must have an entry in some basic data table). While XML solves this (to some extend) with XSD and DTD, we end up hacking this again and again for proprietary text file formats. Is there any library or framework that allows the creation of templates similar to the xsd approach ? This would make it way more flexible to react on file format changes or implement new formats. Thanks for any hints Sven

  • pushViewController for same instance - only for animation purpose

    - by techastute
    Hi there, I am having single table view in a view controller. That table view lists the countries first. When I click on a country(row), it has to push the same view controller's view with cities under that country. I need to see the slide animation, which we usally get while pushing views in navigator. Is it possible to use the pushViewController for the same view controller by calling the tableView reloadData with city data (This should happen when country is selected) ? Please let me know whether it is possible.. Thanks in advance.. Raj

  • Returning the value of an identity column during/after SQL INSERT command

    - by Adam Kane
    Using VS 2010, with ASP.NET, and .NET 3.0, and C#... When I use a System.Web.UI.WebControls.SqlDataSource and call its Insert() method to insert a new row, and that table has an identity column, I'd like my method to return the value of that column. For example, in my SQL 2005 table, I've got: Customer.Id Customer.FirstName Customer.LastName Where Customer.Id is an identity colum. When I call my method InsertNewCustomerRecord( "John", "Smith" ), I'd like to be able to return the Customer.Id that gets automatically generated in the database. Sorry for such a roughly posed question. Let me know if I can add better detail. Thanks.

  • Is there a way to tell Drupal not to cache a specific page?

    - by TechplexEngineer
    I have a custom php page that processes a feed of images and makes albums out of it. However whenever i add pictures to my feed, the Drupal page doesn't change until I clear the caches.

  • Optimising speeds in HDF5 using Pytables

    - by Sree Aurovindh
    The problem is with respect to the writing speed of the computer (10 * 32 bit machine) and the postgresql query performance.I will explain the scenario in detail. I have data about 80 Gb (along with approprite database indexes in place). I am trying to read it from Postgresql database and writing it into HDF5 using Pytables.I have 1 table and 5 variable arrays in one hdf5 file.The implementation of Hdf5 is not multithreaded or enabled for symmetric multi processing.I have rented about 10 computers for a day and trying to write them inorder to speed up my data handling. As for as the postgresql table is concerned the overall record size is 140 million and I have 5 primary- foreign key referring tables.I am not using joins as it is not scalable So for a single lookup i do 6 lookup without joins and write them into hdf5 format. For each lookup i do 6 inserts into each of the table and its corresponding arrays. The queries are really simple select * from x.train where tr_id=1 (primary key & indexed) select q_t from x.qt where q_id=2 (non-primary key but indexed) (similarly five queries) Each computer writes two hdf5 files and hence the total count comes around 20 files. Some Calculations and statistics: Total number of records : 14,37,00,000 Total number of records per file : 143700000/20 =71,85,000 The total number of records in each file : 71,85,000 * 5 = 3,59,25,000 Current Postgresql database config : My current Machine : 8GB RAM with i7 2nd generation Processor. I made changes to the following to postgresql configuration file : shared_buffers : 2 GB effective_cache_size : 4 GB Note on current performance: I have run it for about ten hours and the performance is as follows: The total number of records written for each file is about 6,21,000 * 5 = 31,05,000 The bottle neck is that i can only rent it for 10 hours per day (overnight) and if it processes in this speed it will take about 11 days which is too high for my experiments. Please suggest me on how to improve. Questions: 1. Should i use Symmetric multi processing on those desktops(it has 2 cores with about 2 GB of RAM).In that case what is suggested or prefereable? 2. If i change my postgresql configuration file and increase the RAM will it enhance my process. 3. Should i use multi threading.. In that case any links or pointers would be of great help Thanks Sree aurovindh V

  • Scraping paginated items from a website using scrapy

    - by Mridang Agarwalla
    I'm using scrapy to scrape items from a site. I'm not being able to implement this scraping pattern. The site I'm trying to scrape is a forum and I scrape the site once a day. Each page has a table containing posts. New posts are added to the top of the table and as more and more posts are posted to the site, the older posts go further into the pages due to pagination. This is a very simple scenario and we will assume that the order of the posts never change. I would like to scrape this site and scrape all the "new" records until the last scraped post from yesterday is encountered. I have configured my spider to paginate endlessly and when it encounters yesterday's last scraped post, it should stop. How can implement this? (My Scrapy installation works with my Django installation using django-dynamic-scraper )

  • jqplot format tooltip values

    - by Jeroen
    I want to have a tooltip hover highlight thingy in jqplot. The problem is that I want it to give more detail then on the axes. So the formatter should be different. I can't get it to display the seconds to: There's a JS fidle here! I want the timestamp to display as hours:minutes:seconds, which would be format string '%H:%M:%S' or '%T' or '%X'. But how do I do that? highlighter: { show: true, sizeAdjust: 3, //useAxesFormatters: false, //tooltipFormatString: '%H:%M:%S', formatString: '<table class="jqplot-highlighter"><tr><td>tijd:</td><td>%s</td></tr><tr><td>snelheid:</td><td>%s</td></tr></table>', },

  • Linq to sql Incorrect varchar length

    - by scott
    I have a table with a nullable varchar(50) column in it. When I am updating the value through linq to sql and trace the call in profiler it is defining the parameter as varchar(36). This is obviously causing some minor issues when we are trying to insert data that is between 37 and 50 characters long. I have tried removing the table and re-adding it to the design surface but the same thing happens. I also tried removing that property and adding it manually, same issue. When I look at the designer.cs code it shows the attribute properly: [Column(Storage="_Name", DbType="VarChar(50)")] I am out of ideas, anybody seen this before? Every other column is correct.

  • Is there alternative way to write this query?

    I have tables A, B, C, where A represents items which can have zero or more sub-items stored in C. B table only has 2 foreign keys to connect A and C. I have this sql query: select * from A where not exists (select * from B natural join C where B.id = A.id and C.value > 10); Which says: "Give me every item from table A where all sub-items have value less than 10. Is there a way to optimize this? And is there a way to write this not using exists operator?

  • Need alternative field names for these reserved words

    - by MattSlay
    “type” and “class” are likely reserved or problematic words in C# and/or Ruby, two languages I may use to program against my new database schema in the future. So, in order to avoid potential conflicts with those languages, I’m looking for alternative names for these field names in my tables. In this case, it is from my Machines table, where I have: “class” field (values would be something like “manual” or “computerized”) and “type” field (values would be “lathe” or “mill”) I could call the fields “machineclass” and “machinetype”, but that is inconsistent with naming scheme in the rest of my schema (meaning, I do not re-use the table name in the field… For instance, I use Machine.name, not Machine.machinename) Any thought on this madness?

  • SqlServer2008 + expensive union

    - by Tim Mahy
    Hi al, we have 5 tables over which we should query with user search input throughout a stored procedure. We do a union of the similar data inside a view. Because of this the view can not be materialized. We are not able to change these 5 tables drastically (like creating a 6th table that contains the similar data of the 5 tables and reference that new one from the 5 tables). The query is rather expensive / slow what are our other options? It's allowed to think outside the box. Unfortunately I cannot give more information like the table/view/SP definition because of customer confidentiality... greetings, Tim

  • Using Entity Framework, how do I specify a sort on a navagation property?

    - by Jared
    I have two tables: [Category], [Item]. They are connected by a join table: [CategoryAndItem]. It has two primary key fields: [CategoryKey], [ItemKey]. Foreign keys exist appropriately and Entity has no problem pulling this in and creating the correct navigation properties that connect the entity objects. Basically each category can have multiple items, and items can be in multiple categories. The problem is that the order of items is specified per category, so that a particular item might be third in one category but fifth in another. In the past, I have added a [Sequence] field to the join table and modified the stored procedure to handle it. But since Entity is replacing my stored procedures, I need to figure out how to make Entity handle the sequence. Any suggestions?

  • Would you use a UITableViewController to implement a check list on the iPhone?

    - by Tony
    I am creating an application that will have a list of items that can be checked. I just implemented it as a Table View by subclassing UITableViewController. Now I am realizing that since individual items don't have a child view (i.e. clicking on an item "Dinner" does not need to pull up a child list of "Dinner Items") then maybe I should have just created a custom view for the list. In your experience, would it be better to use the Table View or create something custom? thanks! p.s. I am a bit new to iPhone dev, but NOT new to C

    Hi, I have a database with a 6 level hierarchy and a domain model on top of that. something like this: Category -SubCategory -Container -DataDescription | Meta data -Data The mapping I'm using follows the following pattern: <class name="Category, Sample" table="Categories"> <id name="Id" column="Id" type="System.Int32" unsaved-value="0"> <generator class="native"/> </id> <property name="Name" access="property" type="String" column="Name"/> <property name="Metadata" access="property" type="String" column="Metadata"/> <bag name="SubCategories" cascade="save-update" lazy="true" inverse="true"> <key column="Id" foreign-key="category_subCategory_fk"/> <one-to-many class="SubCategory, Sample" /> </bag> </class> <class name="SubCategory, Sample" table="SubCategories"> <id name="Id" column="Id" type="System.Int32" unsaved-value="0"> <generator class="native"/> </id> <many-to-one name="Category" class="Category, Sample" foreign-key="subCat_category_fk"/> <property name="Name" access="property" type="String"/> <property name="Metadata" access="property" type="String"/> <bag name="Containers" inverse="true" cascade="save-update" lazy="true"> <key column="Id" foreign-key="subCat_container_fk" /> <one-to-many class="Container, Sample" /> </bag> </class> <class name="Container, Sample" table="Containers"> <id name="Id" column="Id" type="System.Int32" unsaved-value="0"> <generator class="assigned"/> </id> <many-to-one name="SubCategory" class="SubCategory,Sample" foreign-key="container_subCat_fk"/> <property name="Name" access="property" type="String" column="Name"/> <bag name="DataDescription" cascade="all" lazy="true" inverse="true"> <key column="Id" foreign-key="container_ DataDescription_fk"/> <one-to-many class="DataDescription, Sample" /> </bag> <bag name="MetaData" cascade="all" lazy="true" inverse="true"> <key column="Id" foreign-key="container_metadata_cat_fk"/> <one-to-many class="MetaData, Sample" /> </bag> </class> For some reason when I try to save the category (with the subcategory, container etc. attached) I get a foreign key violation from the database. The code is something like this (Pseudo). var category = new Category(); var subCategory = new SubCategory(); var container = new Container(); var dataDescription = new DataDescription(); var metaData = new MetaData(); category.AddSubCategory(subCategory); subCategory.AddContainer(container); container.AddDataDescription(dataDescription); container.AddMetaData(metaData); Session.Save(category); Here is the log from this test : DEBUG NHibernate.SQL - INSERT INTO Categories (Name, Metadata) VALUES (@p0, @p1); select SCOPE_IDENTITY(); @p0 = 'Unit test', @p1 = 'unit test' DEBUG NHibernate.SQL - INSERT INTO SubCategories (Category, Name, Metadata) VALUES (@p0, @p1, @p2); select SCOPE_IDENTITY(); @p0 = '1', @p1 = 'Unit test', @p2 = 'unit test' DEBUG NHibernate.SQL - INSERT INTO Containers (SubCategory, Name, Frequency, Scale, Measurement, Currency, Metadata, Id) VALUES (@p0, @p1, @p2, @p3, @p4, @p5, @p6, @p7); @p0 = '1', @p1 = 'Unit test', @p2 = '15', @p3 = '1', @p4 = '1', @p5 = '1', @p6 = 'unit test', @p7 = '0' ERROR NHibernate.Util.ADOExceptionReporter - The INSERT statement conflicted with the FOREIGN KEY constraint "subCat_container_fk". The conflict occurred in database "Sample", table "dbo.SubCategories", column 'Id'. The methods for adding items to objects is always as follows: public void AddSubCategory(ISubCategory subCategory) { subCategory.Category = this; SubCategories.Add(subCategory); } What am I missing?? Thanks, nisbus

  • T-SQL error object exists when separated in if/else blocks

    - by Jeff O
    I get the error: Msg 2714, Level 16, State 1, Line 16 There is already an object named '#mytemptable' in the database. There are ways around it, but wonder why this happens. Seems like SQL Server is verifying both blocks of the if/else statement? declare @choice int select @choice = 1 if @choice = 1 begin select 'MyValue = 1' AS Pick into #my_temp_table end else begin select 'MyValue <> 1' AS Pick into #my_temp_table end select * from #temptable drop table #temptable If the tables have different names, it works. Or if I create the temp table and use Insert Into... statements that works as well.
