enter

This may seem like a stupid question, but I've been searching and can't find an answer. I'm creating an android application and within it there is a button that will send some information in an email, and I don't want to have everything all in one paragraph. Here's what my app is doing for the putExtra for the email's body: I am the first part of the info being emailed. I am the second part. I am the third part. Here's what I want it to do: I am the first part of the info being emailed. I am the second part. I am the third part. How would I put a new line into a string or with the putExtra

So I've been doing a little bit of reading up on how to exit a while loop by the user pressing the enter key and I've come up with the following: import sys, select, os switch = 1 i = 1 while switch == 1: os.system('cls' if os.name == 'nt' else 'clear') print "I'm doing stuff. Press Enter to stop me!" print i while sys.stdin in select.select([sys.stdin], [], [], 0)[0]: line = raw_input() if not line: print "Finished! =]" switch = 0 else: print "Finished! =]" switch = 0 i = i+1 Is there a way to tidy this up? In particular the "if not line" and the following "else" look messy. Can they be

The .val() property of an item in jQuery for a <textarea> doesn't seem to work with new lines. I need this function as the text-area is meant to recognize the enter key and display it as a preview, with the new line in tact. However, what happens is shown in this fiddle: http://jsfiddle.net/GbjTy/1/ . The text is displayed, but not in a new line. How can I achieve the preview to include new lines, and I know it is possible, because it does this in the Stack Overflow Post Question preview. Thanks. P.S I have seen other links on SO relating to this, but they all say get the End User to use some

```python with obj as f: '代码块' 1.with obj ----》触发obj.__enter__(),拿到返回值 2.as f----->f=返回值、 3.with obj as f 等同于 f=obj.__enter__() 4.执行代码块 一：没有异常的情况下，整个with代码块运行完毕后去触发__exit__,它的三个参数都为None 二：有异常的情况下，从异常出现的位置直接触发__exit__ a：如果__exit__的返回值为True，代表吞掉了异常 b：如果__exit__的返回值不为True，代表吐出了异常 c：__exit__的的运行完毕就代表了整个with语句的执行完毕。 若为a情况，with里面的语句，后面部分不会执行，执行with外面的语句 若为b情况，报出异常，后面的所有代码全部不会执行 好处：不用手动关闭这个存在内存中的obj，with代码执行完毕或遇到异常时，触发__exit__,二这里面可以自定义自动释放资源的机制，结束掉内存中的obj 比如文件处理，网络连接等等 ``` 当执行with 语句时,会先执行enter ,当代码执行完毕后执行exit,或者代码遇到了异常会立即执行exit,并传入错误信息包含错误的类型.错误的信息.错误的追踪信息 ``` enter 函数应该返回对象自己 exit函数 可以有返回值

I want to disable the beep sound that i get when i press enter in a textbox . My KeyDown event is: private void textBox_Zakljucak_KeyDown(object sender, KeyEventArgs e) { if ((e.KeyCode == Keys.Enter) || (e.KeyCode == Keys.Tab)) { Parent.SelectNextControl(textBox_Zakljucak, true, true, true, true); } else if ((e.KeyCode == Keys.Back)) { textBox_Zakljucak.Select(textBox_Zakljucak.Text.Length, 0); } else if (!Regex.IsMatch(textBox_Zakljucak.Text, @"^[0-9.-]+$")) { textBox_Zakljucak.Clear(); textBox_Zakljucak.Select(textBox_Zakljucak.Text.Length, 0); } } You have to prevent the KeyPressed event
