backspace

I have my CKEDITOR form prepopulated with hidden table which is being submitted together with user inputed text. This works fine, but sometimes user presses backspace too many times and deletes the hidden table. Is there a way to block editing on this hidden table inside ckeditor textarea? So when user presses backspace the hidden table isn't affected and stays in. As soon as CKEDITOR instance is ready this source (bellow) is put inside CkEditor Textarea (using setData() attribute) and User only sees the returned <p></p> value. In this case its <p>I really think I can do this!</p> . Its a

This program copy its input to its output, replacing TAB( \t ) by \t backspace( \b ) by \b . But here in my code I am unable to read input character when I enter backspace its not replacing as a tab works . Compiling with GCC in Linux: #include<stdio.h> int main(void) { int c=0; while((c=getchar())!=EOF){ if(c=='\t'){ printf("\\t"); if(c=='\b') printf("\\b"); } else putchar(c); } return 0; } Suppose if I type vinay (tab) hunachyal Output:vinay\thunachyal If I type vinay(and 1 backspace) Output:vina So my query is why vina\b is not printing in this case? Is it possible to detect \b and print \b

In Vim, when I hit the backspace key in the insert mode, it leaves ^? character and does not delete the character it is suppose to delete. I have the following in my .vimrc syntax on set number set expandtab set incsearch set nocompatible set backspace=indent,eol,start fixdel This happens in the command mode too. When I wrongly type W instead of w to save, I press backspace key and it gives me the following: :W^? Any idea on whats wrong and how to fix it?! UPDATE: before posting this question to SO, I have done a basic google search and tried all the suggestion from the first page of search

There are several folks on here looking for backspace answers in Python. None of the questions I have searched have answered this for me, so here goes: The Simple Goal : be able to print out a status string on one line, where the next status overwrites the first. Similar to a % complete status, where instead of scrolling a long line of 1%\n, 2%, ... etc. we just overwrite the first line with the newest value. Now the question. When I type this in idle: print("a\bc") I get this as output: ac with what looks like an odd box with a circle between the 'a' and 'c'. The same thing happens when using

How can I detect when a user pressed "return" keyboard button while editing UITextField? I need to do this in order to dismiss keyboard when user pressed the "return" button. Thanks. Ilya Suzdalnitski - (BOOL)textFieldShouldReturn:(UITextField *)textField { [textField resignFirstResponder]; return NO; } Don't forget to set the delegate in storyboard... Delegation is not required, here's a one-liner: - (void)viewDidLoad { [textField addTarget:textField action:@selector(resignFirstResponder) forControlEvents:UIControlEventEditingDidEndOnExit]; } Sadly you can't directly do this in your

I wonder why backspace character in common Linux terminals does not actually erase the characters, when printed (which normally works when typed).. This works as expected: $ echo -e "abc\b\b\bxyz" xyz ( \b evaluates to backspace, can be inserted also as Ctrl + V Ctrl + H - rendered as ^H ( 0x08 )) but when there are less characters after the backspaces, the strange behavior is revealed: $ echo -e "abc\b\b\bx" xbc it behaves like left arrow keys instead of backspace: $ echo -e "abc\e[D\e[D\e[Dx" xbc erase line back works normally: $ echo -e "abc\e[1Kx" x In fact, when I type Ctrl + V Backspace
