  • Using variables for colors in table cells

    - by Mark Robinson
    Using the variables extension, I want to change the background color of a cell in a table. So far I've done this: {{#vardefine:green|<span style="background:Green; color:White">text</span>}} The problem is that, when I add {{#var:green}} to the cell, only the text itself has a green background. Ideally, I want the whole cell to have a background color, like it does if I use this: | bgcolor="#ff00ff" | test or this | style="background:silver" |silver in the cell. Does anyone know how to solve this?

  • AES Key encoded byte[] to String and back to byte[]

    - by Tom Brito
    In the similar question "Conversion of byte[] into a String and then back to a byte[]" is said to not to do the byte[] to String and back conversion, what looks like apply to most cases, mainly when you don't know the encoding used. But, in my case I'm trying to save to a DB the javax.crypto.SecretKey data, and recoverd it after. The interface provide a method getEncoded() which returns the key data encoded as byte[], and with another class I can use this byte[] to recover the key. So, the question is, how do I write the key bytes as String, and later get back the byte[] to regenerate the key?

  • Two-key encryption/decryption?

    - by Matt
    I'm looking to store some fairly sensitive data using PHP and MySQL and will be using some form of reversible encryption to do so since I need to get the data back out in plain text for it to be of any use. I'll be deriving the encryption key from the users' username/password combination but I'm stumped for what to do in the (inevitable) event of a password being forgotten. I realise that the purpose of encryption is that it can only be undone using the correct key but this must have been addressed before.. I'm trying to get my head around whether or not public key cryptography would apply to the problem but all I can think of is that the private key will still need to be correct to decrypt the data.. Any ideas?

  • Show transparent color filter on a View after clicking it

    - by Maarten
    So. You know how when you click a post in the Google+ app, the entire View becomes blue. I want to do that as well, but with an ImageView. I have the following code snippet, setting the actual image as the background and the selector as the main resource. This looks good, but doesn't respect scaleType for the background image: <ImageView android:id="@+id/painting_image" android:layout_width="match_parent" android:layout_height="200dp" android:background="@drawable/img" android:src="@drawable/selector" android:scaleType="centerCrop" /> By the way, @drawable/selector is just a selector that shows a tranparent color for state_pressed: <item android:state_pressed="true"> <shape xmlns:android="http://schemas.android.com/apk/res/android"> <solid android:color="#44521400" /> </shape></item> How can I make this work while respecting the scaleType?

  • adding a background color to search term results

    - by turborogue
    I'm trying to add a background color to a user submitted search result when a user enters a search term on a page (which is basically one big table). This is a text based search. I'm using jquery to show/hide the table rows that do not have the search term as text within the TR, but I'd ideally like to take the additional step of taking the search term (the entered value), and matching any of those text terms in the remaining (showing) rows and adding say a yellow background to the word(s). I know my syntax is currently wrong, just not sure what is correct:) Hopefully this is clear...any help is greatly appreciated! html of form: jquery: $("#searchsubmit").click(function () { var searchexp = document.getElementById('searchbox').value; $("table tr").hide(); $("table tr.header").show(); $('tr:contains('+ searchexp +')').show(); $(searchexp).css('background-color','yellow'); });

  • simulate to change the background color when click the link

    - by tom
    I have the following HTML and the java script below to simulate the background color change when the link block is clicked, but it doesn't seem to work. Any reason why? If I have only the onmousedown event handled, the background color will be changed to blue for sure. But if both onmousedown and onmouseup are handled, nothing would change visually. note... function changeColorOnMouseDown() { document.getElementById('note').style.background='blue'; } function changeColorOnMouseUp() { document.getElementById('note').style.background='#d8dde7'; }

  • Is foreign key reference from two different primary key from two different tables valid?

    - by arundex
    I have a foreign key that has to refer primary keys of two different tables. Table 1: animal animal_ id (primary key) Table 2: bird bird_ id (primary key) Table 3: Pet_info pet_id, type ENUM ('bird', 'animal') foreign key (pet_ id) references animal(animal_id), bird(bird_id) So, I need to check for pet_id either from animal or bird table depending on the need. Is this valid? Or should I go for some restructuring . . . NOTE: I referred this . . but I'm not sure whether I have to change my existing design

  • Using a user-defined type as a primary key

    - by Chris Kaminski
    Suppose I have a system where I have metadata such as: table: ====== key name address ... Then suppose I have a user-defined type described as so: datasource datasource-key A) are there systems where it's possible to have keys based on user-defined types? B) if so, how do you decompose the keys into a form suitable for querying? C) is this a case where I'm just better off with a composite primary key?

  • Command line tool (PDF Workflow) in OSX that detects if key is down

    - by kroko
    Hello! I'm writing a OSX PDF Workflow in ObjC and C. A single executable ("UNIX Tool" as named in the Apple reference), that reads in the spooled PDF file, does some parsing. I'd like to give more functionality by enabling a key-down event handling, meaning - when user opens print dialog in an application - and chooses to left-mouse-click on the custom made pdf workflow to run it - depending on if a keyboard key is down (i.e. option key, but "any key down" would be enough for me) when running that workflow - a decision is made in the code. I have read NSEvent and Carbon Event Manager reference and it seems that in this case (a plain unix executable + not run as root) it's not possible. Or is it? Many thanks in advance, Kroko

  • Conditionally setting the font color of an item in a drop down box in JSF

    - by Greg
    I'm a newbie to web programming, so please bear with me. I am using JSF 1.2 and I want to conditionally set the color of the items in my drop down list. In other words, I have a collection of items that, along with a key and a value, also have a boolean property, warning, that is dynamically set by user action. I want the drop down to show all of the items, but those whose warning property is set to true should be displayed in red. I assume I have to extend the SelectItem class to add in the boolean property. How do I then conditionally set the color of the font of those items whose warning property is set to true in my JSP pages? Thanks in advance

  • Dealing with Android devices without MENU key

    - by hgpc
    I'm told by some users that my Android app is not usable because their device does not have a MENU key. What's the best way to deal with these devices? Is it possible to detect if the device lack a MENU key and show a menu button only in this case? And most importantly, how do you test this in the simulator? Thanks. Edit: Apparently the problem was that the users didn't know that the Menu key was called the Menu key.

  • When to use a foreign key in MySQL

    - by Mel
    Is there official guidance or a threshold to indicate when it is best practice to use a foreign key in a MySQL database? Suppose you created a table for movies. One way to do it is to integrate the producer and director data into the same table. (movieID, movieName, directorName, producerName). However, suppose most directors and producers have worked on many movies. Would it be best to create two other tables for producers and directors, and use a foreign key in the movie table? When does it become best practice to do this? When many of the directors and producers are appearing several times in the column? Or is it best practice to employ a foreign key approach at the start? While it seems more efficient to use a foreign key, it also raises the complexity of the database. So when does the trade off between complexity and normalization become worth it? I'm not sure if there is a threshold or a certain number of cell repetitions that makes it more sensible to use a foreign key. I'm thinking about a database that will be used by hundreds of users, many concurrently. Many thanks!

  • Excel VBA: Alternate Row Color in Range

    - by Kurt
    I spent a VERY long time today looking up a method to alternate row colors within a specified range. There really isn't a lot out there and to be honest what I found just looked over-complicated. So, I decided to stop acting like a shameless 'script-kiddy' and put the below sample together: Sub AlternateRowColors() Dim lastRow as Long lastRow = Range("A1").End(xlDown).Row For Each Cell In Range("A1:A" & lastRow) ''change range accordingly If Cell.Row Mod 2 = 1 Then ''highlights row 2,4,6 etc|= 0 highlights 1,3,5 Cell.Interior.ColorIndex = 15 ''color to preference Else Cell.Interior.ColorIndex = xlNone ''color to preference End If Next Cell End Sub Now I know that works, but I was wondering if there's a simpler method? If so, please do tell because I'm very eager to learn simplification as I have a tendency to write verbose code at present. If not, then may this entry find it's way to page 1 of Google for it's search term(s), because it took me absolutely ages to find anything even remotely useful. Comments left for script-kiddies' benefit.
