So I was browsing through google's april fool's jokes, and I found this one
http://www.google.com/landing/elegantizr/
Which claims to load super fast css, but does this instead
http://shodor.org/~amalani/elegantizr.html
using this code
:before {
content: '\41\50\52\49\4C\20\46\4F\4F\4C\20\F4\BF\F4';
}
What format is this, and how does it work?
The content property specifies content to insert into your html. It must be paired with either the :before or :after selector in order to specify where that content would be inserted. Intended use is that the before or after selector is applied to an element. For example:
.copyright:before {content: "\00A9 ";}
Would add a copyright symbol to the front of every element with the class "copyright". CSS has it's own way of doing what in HTML are character entities. More info can be found # css-tricks.com/css-content/. This is where I learned most of what I know about it.
In this case, though, they did not specify which element to apply this to, therefor, it is applied to all elements.
So the character codes used in the elegantizer are as follows:
\41 = A
\50 = P
\52 = R
\49 = I
\4C = L
\20 = space
\46 = F
\4F = O
\4F = O
\4C = L
\20 = S
\F4 = ô
\BF = ¿
\F4 = ô
A full list of unicode characters can be found at the List of Unicode Characters Wiki. Simply remove the leading zeros and precede them with a backslash.

How do I use regex to find FS.File on FS.Collection in meteor. My code is as follows and it is not working
partOfFileName = "*User_" + clickedResellerId + "_*";
var imgs = Images.find({fileName:{$regex:partOfFileName}});
//var imgs = Images.find();
return imgs // Where Images is an FS.Collection instance
In place of fileName I've also tried name and it is not working either. Please help
I don't think your regex is valid. Did you perhaps mean the following?
partOfFileName = ".*User_" + clickedResellerId + "_.*";
Please note that POSIX wildcard notation is different from regular expressions. in Regular expressions the * operators indicates repetition of the preceding operator (in my case a ., i.e., anything). A * by itself has no meaning, and it doesn't mean "anything" like in POSIX.
i need to put all text of a docx in a stringBuilder, also with tab and hyphen.
i've tried the use of org.docx4j.TextUtils, but in the resultant string doesn't seen tab.
String inputfilepath = System.getProperty("user.home") + "test.docx";
WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load(new java.io.File(inputfilepath));
MainDocumentPart documentPart = wordMLPackage.getMainDocumentPart();
org.docx4j.wml.Document wmlDocumentEl = (org.docx4j.wml.Document)documentPart.getJaxbElement();
Writer out = new OutputStreamWriter(System.out);
extractText(wmlDocumentEl, out);
out.close();
As per my answer at http://www.docx4java.org/forums/docx-java-f6/is-it-possible-to-extract-all-text-also-tab-and-hyphen-t1996.html#p6933?sid=b0d58fec2ba349d0f3f49cf66411397c
The problem with tab and hyphen, as I guess you know, is that they aren't represented in the docx as normal characters.
Tab is w:tab
A hyphen might be a hyphen character, or it might be displayed (without being actually in the docx), or it might be:
http://webapp.docx4java.org/OnlineDemo/ecma376/WordML/noBreakHyphen.html
or http://webapp.docx4java.org/OnlineDemo/ecma376/WordML/softHyphen.html
Replicating Word's hyphenation behaviour would be a challenge.
But for the others, there are three approaches which occur to me:
generalising your traverse approach (are you using TraversalUtil.getChildrenImpl?)
doing it in XSLT (you can do this in docx4j, but XSLT is probably slower, and a mix of technologies)
marshal the main document part to a string, do suitable string replacements, then unmarshal, then use TextUtils
For (3), assuming MainDocumentPart mdp, to get it as a String:
String stringContent = mdp.getXML();
Then to inject the modified content:
mdp.setContents((Document)XmlUtils.unmarshalString(stringContent) );
The URL link below will open a new Google mail window. The problem I have is that Google replaces all the plus (+) signs in the email body with blank space. It looks like it only happens with the + sign. How can I remedy this? (I am working on a ASP.NET web page.)
https://mail.google.com/mail?view=cm&tf=0&to=someemail#somedomain.com&su=some subject&body=Hi there+Hello there
(In the body email, "Hi there+Hello there" will show up as "Hi there Hello there")
The + character has a special meaning in [the query segment of] a URL => it means whitespace: . If you want to use the literal + sign there, you need to URL encode it to %2b:
body=Hi+there%2bHello+there
Here's an example of how you could properly generate URLs in .NET:
var uriBuilder = new UriBuilder("https://mail.google.com/mail");
var values = HttpUtility.ParseQueryString(string.Empty);
values["view"] = "cm";
values["tf"] = "0";
values["to"] = "someemail#somedomain.com";
values["su"] = "some subject";
values["body"] = "Hi there+Hello there";
uriBuilder.Query = values.ToString();
Console.WriteLine(uriBuilder.ToString());
The result:
https://mail.google.com:443/mail?view=cm&tf=0&to=someemail%40somedomain.com&su=some+subject&body=Hi+there%2bHello+there
If you want a plus + symbol in the body you have to encode it as 2B.
For example:
Try this
In order to encode a + value using JavaScript, you can use the encodeURIComponent function.
Example:
var url = "+11";
var encoded_url = encodeURIComponent(url);
console.log(encoded_url)
It's safer to always percent-encode all characters except those defined as "unreserved" in RFC-3986.
unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
So, percent-encode the plus character and other special characters.
The problem that you are having with pluses is because, according to RFC-1866 (HTML 2.0 specification), paragraph 8.2.1. subparagraph 1., "The form field names and values are escaped: space characters are replaced by `+', and then reserved characters are escaped"). This way of encoding form data is also given in later HTML specifications, look for relevant paragraphs about application/x-www-form-urlencoded.
Just to add this to the list:
Uri.EscapeUriString("Hi there+Hello there") // Hi%20there+Hello%20there
Uri.EscapeDataString("Hi there+Hello there") // Hi%20there%2BHello%20there
See https://stackoverflow.com/a/34189188/98491
Usually you want to use EscapeDataString which does it right.
Generally if you use .NET API's - new Uri("someproto:with+plus").LocalPath or AbsolutePath will keep plus character in URL. (Same "someproto:with+plus" string)
but Uri.EscapeDataString("with+plus") will escape plus character and will produce "with%2Bplus".
Just to be consistent I would recommend to always escape plus character to "%2B" and use it everywhere - then no need to guess who thinks and what about your plus character.
I'm not sure why from escaped character '+' decoding would produce space character ' ' - but apparently it's the issue with some of components.
i have a page in which i am displaying the name of all the users i want to filter their names on the basis of first character for that i want to show A B C D ....X Y Z filters on the top on clicking of which it will filter the names accordingly my problem is not the query part but how to add these letters do i have to add 26 link buttons separately or there is some work around for example you might have seen such type of behavior in some music sites for filtering the songs with starting character.
These are few useful links how to do alphabetical paging
1. http://www.highoncoding.com/Articles/209_GridView_Alphabet_Paging.aspx
2. http://aspdotnetcodebook.blogspot.com/2008/03/how-to-add-alphabet-paging-in-gridview.html
Use ASCII characters codes to do this, for example:
var letters = new List<string>()
for(int i = 65; i < 91; i++)
letters.Add(Convert.ToChar(i).ToString());
Display it by adding links to page:
foreach(letter in letters)
{
var hyperlink = new Hyperlink()
{
NavigateUrl = string.Format("Filter.aspx?letter={0}", letter),
Text = letter
}
Page.Controls.Add(hyperlink);
}
Of course instead of Page you can use any other container you want, you just need to add those hyperlinks to controls collection.
Also take care to run this code in proper method, for example by overriding CreateChildControls method.

I would like to know the easiest way to format a string as accounting style. I know how to format as currency using {0:c} but there are some differences in accounting style, for example, all the dollar signs will line up as well as all the decimal points, and negatives are expressed in parenthesis rather than with a "-" minus sign. You can find a good example of the way i would like it in excel if you format the cells as "accounting" with 2 decimal places.
Ignoring your alignment requirements, you could use
number.ToString("€#,##0.00;(€#,##0.00);Zero")
to bracket negative numbers.
To align your numbers, you'd have to format without the currency symbol, and pad the formatted numbers yourself with spaces, using a fixed width font would make this job easier for you.
EDIT:
It seems String.Format is your friend:
String.Format("{0,15:#,##0.00 ;(#,##0.00);- }", number)
where 15 is the total width of the output, and you need to append this text to your currency symbol. (Again, this aligns in fixed width only)
There's no format string shortcut (the single-character ones with default rules) for handling accounting style formats (here's a cheat sheet with the available format strings) so you'll have to write a more specific one (like Patrick's answer) or your own parsing method.
The alignment requirements would be specific to how you're displaying them. I'm assuming you are using a table, in which case you're limited by what HTML supports, and it doesn't support accounting style alignments like Excel.
In this blog there were some various formats outlined and this one seemed to be close to what you were looking for:
int neg = -10;
int pos = 10;
// C or c (Currency): It represent how many decimal place of zeros to show.
String.Format("{0:C4}", pos); //"$10.0000"
String.Format("{0:C4}", neg); //"($10.0000)"
It doesn't handle the padding (you may have to fix that yourself), but it does have the proper parenthesis.
You could do something using a variation of Patricks method. This will handle formating and alignment assuming you know the upper bound of how large a value you are dealing with:
private static string OutputAsCur(decimal val)
{
string format = " #,##0.00 ; (#,##0.00);Zero";
string frmt = val.ToString(format);
return CultureInfo.CurrentCulture.NumberFormat.CurrencySymbol + frmt.PadLeft(15, ' ');
}
Here's a simple example app to see it format:
static void Main(string[] args)
{
decimal d = 155.55m;
Console.WriteLine(OutputAsCur(d));
Console.WriteLine(OutputAsCur(d * -1));
Console.WriteLine(OutputAsCur(1002.32m));
Console.WriteLine(OutputAsCur(1002.32m * -1));
Console.ReadLine();
}
You can use a format string for String.Format to get what you're trying to accomplish. The only trick is that positive numbers, since they will not have a closing parenthesis mark, will have to incorporate a space at the end if they will be aligned with any negative numbers that will be in the column. The trick is to get that space into the string in a way that HTML will not ignore. I simply use the HTML entity which indicates a non-breaking space in HTML.
Here's sample code. First, in the aspx.
<table>
...
<tr>
<th scope="row" colspan="2">Total Revenue</th>
<td class="numeric total"><asp:Label runat="server" ID="TotalRevenueLabel" /></td>
</tr>
...
</table>
Now, the codebehind.
public const string kMoneyFormat = "#,#.00' ';(#,#.00);'-.-- '";
public void DataBind()
{
using (FinancialDataContext sql = new FinancialDataContext())
{
var periodQuery = from m in sql.Forecasts()
select m;
ForecastsResult periodData = periodQuery.Single();
decimal totalRevenue = period.Data.income_actual.Value + periodData.other_income.Value;
TotalRevenueLabel.Text = totalRevenue.ToString(kMoneyFormat);
}
}
I followed these steps for apply the "Accounting" format.
In a new Book on Excel, select a cell.
Insert data (i.e any number; for this example, add 80000).
Select (Accounting) NumberFormat as is shown in the screenshot #1:
Screenshot #1:
Select "More Number Formats".
Select "Custom".
Select any of the pre-defined formulas (see screenshot #2).
Screenshot #2:
In my case, this is the desired format for this number.
The negative side of this is that when you select the cell with the format applied on it, you wont see selected (Accounting) "in the DropDownList" Number Format.
