A program written in C # to delete a carriage return, newline, tab, and space in a string

When using the Cajviewer (I used the version 7.2.0 build 111) to consult the literature, the text is copied in Notepad resulting in multiple line breaks, as shown in:

There is no doubt that manually deleting the carriage return (\ n), line break (\ r), tab (\ t), and whitespace are deleted, which is very time-consuming and laborious. About one months ago, I wrote a very simple gadget in C # to solve this problem, and today I write down the code of the tool to make it easier to use later.

Program Interface

This program's window is set to always in the front, will be cajviewer in the "Select text" status selected text, press CTRL + C copy, press CTRL + V paste in the program text editing interface, click the "Convert" button, the program will automatically delete the carriage return, line breaks, tabs, spaces four characters, click "Copy "You can copy the newly generated text directly to the Clipboard and click" Reset "to empty the text editing interface. For ease of use, I also set the shortcut keys (alt+z, Alt+x, alt+c) for these three buttons, and then click to complete a set of combo! copied from Cajviewer from left to right.
