Hello every one here i am Generating a BarCode using Font Free 3 of 9 like this in a .rdlc Report Page.
<Textbox Name="ID">
<rd:DefaultName>ID</rd:DefaultName>
<Top>1.1in</Top>
<Width>1.15 in</Width>
<Style>
<FontFamily>Free 3 of 9</FontFamily>
<FontSize>28pt</FontSize>
<TextAlign>Center</TextAlign>
<PaddingLeft>2pt</PaddingLeft>
<PaddingRight>2pt</PaddingRight>
<PaddingTop>2pt</PaddingTop>
<PaddingBottom>2pt</PaddingBottom>
</Style>
<ZIndex>6</ZIndex>
<Left>2.26406in</Left>
<Height>0.59063in</Height>
<Value>= "*" & Fields!ID.Value & "*" </Value>
</Textbox>
But the Scanner i have isn't reading it its not scanning it at all. Can any one help where is the error. Its a ID that gets to be printed and should be Scan able but its doesn't Scan. what other Font could Replace it ? It creates the BarCode looks fine prints and every thing Converts to PDF but doesn't Scan.
If your barcode ends in "62462", then all the bars and spaces that describe the previous characters are missing, including the initial "*" start symbol. In other words, the png file in the link above only shows the right hand side of the barcode, but I can't tell how much of the left or "start" of the barcode is cut off. I'm guessing the barcode is being clipped by some bounding rectangle.
Increase the width that you give the image generated by the textbox, and you may be okay.
When working with Code 3 of 9, the start and end of the barcode has a very distinctive look because of the asterisks on each side of the data. It looks like this:
If you work with Code 39 long enough, you'll recognize a code 39 barcode a mile away because of the symbol associated with the asterisks. Thin bar, thick space, then thin, thick, thick, thin bars separated by thin spaces.

I need to indent some math stuff in the \details section of my .Rd documentation to enhance its readability. I am using mathjaxr. Is there any way to indent without installing roxygen2 or similar?
The math stuff is inline, so simply setting to display using \mjdeqn won't solve this.
I seem to have a reasonable "cheating" work around for indenting the first line using mathjaxr, at least for the PDF and HTML output.
We need to do two things:
Use the mathjax/LaTeX phantom command. phantom works by making a box of the size necessary to type-set whatever its argument is, but without actually type-setting anything in the box. For my purposes, if I want to indent, say, about 2 characters wide, I would start the line with a \mjeqn{\phantom{22}}{ } and following with my actual text, possibly including actual mathy bits. If I want an indent of, say, roughly 4 characters wide, I might use \mjeqn{\phantom{2222}}{ }.
Because mathjaxr has a problem with tacking on unsolicited new lines when starting a line with mjeqn, we need to prefix the use of phantom in 1 above with an empty bit of something non-mathjaxr-ish like \emph{}.
Putting it all together, I can indent by about 2 characters using something like this:
\emph{}\mjeqn{\phantom{22}}Here beginneth mine indented line…
I need to explore whether the { } business actually indents for ASCII output, or whether I might accomplish that using or some such.
I've created a little Xmobar status indicator for https://complice.co. Inspired by the agnoster Zsh theme, I used some box-drawing characters to try to put triangle-like ends on the end of the status bar. But they aren't aligning correctly, as shown here:
The triangle is too small, leaving a lip at the bottom. It annoys me that it's not pixel-perfect. Does anyone have any insight into why it isn't sized correctly? I've never used box-drawing characters and couldn't find any documentation on the specific ones I'm using (\ue0b2 and \ue0b0) - any links would be appreciated.
I use a script to generate the text. The important part is here where I use the box-drawing characters: https://github.com/d4hines/beth/blob/master/scripts/complice#L38
And the Xmobar config: https://github.com/d4hines/beth/blob/master/flake.nix#L249-L265
I open a file in unix with vi, then do the search using /, it finds an occurrence but it also displays # symbol at the bottom, when I try to scroll down, the # symbol disappears. I'm not sure if this # symbol was something I entered accidentally when I was modifying the the file last time.
Have a look at :
http://nixdoc.net/man-pages/HP-UX/vi.1.html
"Terminals with limited local intelligence
might display lines on the screen marked with an #. These indicate
space on the screen not corresponding to lines in the file. (These
lines can be removed by entering a ^R, forcing the editor to retype
the screen without these holes.)"
I am a Java beginner with a question about the operation of the Digitalclock.java example in Netbeans 8.0.2
I want to alter the display to show only Hours and Minutes and change the color. I have found within the code a way to eliminate the display of the Seconds digits and change the color. What I can't do is get rid of the ":" or center the display.
1) Where is the ":" being generated from?
2) How would I center the display?
Thank you,
The colon ":" in this case is not an actual character rather it is being generated by using multiple instances of the java circle class and can be found in line 114 - 117 of the DigitalClock.java file. Centering the the new four digit clock can be accomplished by changing the clock.setLayoutX at line 78. – Six just now edit

What I want the output format is as the following.
In this example, prettytable.py can not display properly chinese ambiguous width of character · in 买买提江·阿布拉 , the character has ambiguous width. How to fix the bug in prettytable.py?
I have add two lines in def _char_block_width(char) of prettytable.py, but the problem still remains.
if char == 0xb7:
return 2
I have solved it, the file prettytable.py should be installed in my computer d:\python33\Lib\site-packagesdirectly not in as the form of d:\python33\Lib\site-packages\prettytable\prettytable.py
There are many chinese character with ambiguous width, it is stupid for us to add two lines such as the following to fix the bug, if there are 50 ambiguous character,100 lines will be added in the prettytable.py, is there a simple way to do that? Just fix some lines to treat all the ambiguous character?
if char == 0xb7:
return 2
The issue you're running into has to do with the dot character in the incorrectly padded line of your Python output. The dot is Unicode code point U+00B7 · middle dot. This character is considered to have an "ambiguous" width, as it is a narrow character in most non-East-Asian fonts, but is rendered a full-width in most Asian ones. Without context, a program can't tell how wide it will appear on the screen. Unfortunately, Python's Unicode system doesn't appear to have any way to provide that context.
One fix might be to replace the offending dot with one that has an unambiguous width, such as U+30FB katakana middle dot (which is always full width). This way the padding logic will be able to recognize that extra space is needed for that line.
Another solution could be to set your console to use a font with more Western treatment of the middle dot character, rather than the current one that follows the East-Asian style of rendering of it as full-width. This will mean that the existing padding is correct. Your output from R clearly uses a different font that the Python output does, and its font renders the dot as half-width.
