Programming :: Print A Line Of Fill Character In C?
May 15, 2010As you know, in C++ you can use setfill(char c); and setwidth( int length) to fill a line of a character.
It's line making a line of a character for output
Code:
NAME DEPARTMENT LOCATION
==========================================
Pete R&D Chicago
...
==========================================
As you see, a line of a '=' character drawn to output.
I'm wondering, how can I draw this line in C using printf() to format?
( no loop or repetiton )
Programming :: Replace Character With Hex Value Choosing From Shell Cmd Line?
Jun 9, 2011I am bouncing a file across platforms (windows->solaris->mainframe), and the file is starting out with a "special" character (the registered trademark "circle R") in some of the records. This character is not in the EBCDIC character set on the MF, so it is unrecognizable. The MF developer I am working with asked if it is possible to replace the character with a specific hex value (AF) before it gets to the MF.
I was putzing around with sed, tr, etc. on the ksh command line, hoping to find an easy way to get one of them to substitute hex instead of ASCII. I have found that the usual shell utilities recognize the trademark character, so homing in on what to replace is solved. But I cannot get anything to actually substitute in the hex sequence I want. E.g. I was thinking something like...
>cat special_file | sed 's/R/AF/g'
But my version of sed does not seem to have hex "editing" capability.

Ubuntu :: Frozen Panel - Messing Around With The Alternate Character Panel App And Made A Custom Character Set
Jun 12, 2011I was messing around with the alternate character panel app and made a custom character set. I then wanted to put it on a new panel and created a new panel. I moved the character set to that panel, and then started to mess around with the panel settings (auto hide, show hide buttons, and expand, to be specific.) So far so good, until I moved the panel from the right side of the screen to the top. I already had a panel here, and it seemed not to like hiding a panel when there was already one on the top.
When the new panel hid itself, all my panels stopped responding (any clicks on them did nothing) and my processor started going at 100%. I tried a reboot and the only thing that changed is that now I can't even see my panels. I'm guessing I need to change the settings back manually through the prompt, but I don't know how to do that. I am using 10.04 and have not upgraded gnome since upgrading to 10.04.

General :: Bind / Map Character To Alt+?
Dec 23, 2009In programming and various terminal programs (Screen, Vim) the [, ], { and } tends to be used a lot. I'm using a Norwegian keyboard where these are placed such that I have to stretch my fingers a bit too long for whats comfortable. To make it easier I though I'd try to make alt+[some key] be one of these characters. Is there a way that I can bind, say alt+� (Norwegian letter) to '{' system wide?Btw, is such thing called binding, mapping or something else? I'm getting a bit confused by the terms...
