multiline

问题 Is there a graceful way in C# to delete multiple lines of text from the beginning of a multiline textbox? I am using Microsoft Visual C# 2008 Express Edition. EDIT - Additional Details The multiline textbox in my application is disabled (i.e. it is only editable by the application itself), and every line is terminated with a "\r\n". 回答1: This is an incomplete question. So assuming you are using either TextBox or RichTextBox you can use the Lines property found inTextBoxBase. //get all the

问题 Entry widgets seem only to deal with single line text. I need a multiline entry field to type in email messages. Anyone has any idea how to do that? 回答1: You could use the Text widget: from tkinter import * root = Tk() text = Text(root) text.pack() root.mainloop() Or with scrolling bars using ScrolledText: from tkinter import * from tkinter.scrolledtext import ScrolledText root = Tk() ScrolledText(root).pack() root.mainloop() 来源： https://stackoverflow.com/questions/9661854/how-to-create-a

问题 Consider the following comma separated file. For simplicity let it contain one line: 'I am quoted','so, can use comma inside - it is not separator here','but can\'t use escaped quote :=(' If you try to read it with the command table <- read.csv(filename, header=FALSE) the line will be separated to 4 parts, because line contains 3 commas. In fact I want to read only 3 parts, one of which contains comma itself. There quote flag comes for help. I tried: table <- read.csv(filename, header=FALSE,

问题 Do you know how to have a two lines menu item title? I've tried using \n in the string or Html.fromHtml with tag but it doesn't work.

问题 Can it be done? We're using VS2005 and VS2008 and VS2010. I don't mean regular expressions - which have their place - but plain old text find & replace. I know we can do it (at a pinch) with regular expressions using the \n tag but prefer not to get tangled up in regex escape characters, plus there's a readability issue. If it can't be done what plain and simple (free) alternative are people using? That doesn't involve knocking up our own macro. 回答1: I finally found it.. No need to download

问题 I am looking for a clean way to use variables within a multiline Python string. Say I wanted to do the following: string1 = go string2 = now string3 = great """ I will $string1 there I will go $string2 $string3 """ I'm looking to see if there is something similar to $ in Perl to indicate a variable in the Python syntax.

问题 According to this article, it's possible to get multiline XML comments -- instead of using /// , use /** */ . This is my interpretation of what multiline comments are, and what I want to have happen: /** * <summary> * this comment is on line 1 in the tooltip * this comment is on line 2 in the tooltip * </summary> */ However, when I use this form, the tooltip that pops up when I hover over my class name in my code is single-line, i.e. it looks exactly as if I had written my comment like this:

问题 I want to have 5 lines for the height of the text area. I am using the following code. <EditText android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center" android:singleLine="false" android:lines="5" android:layout_marginLeft="10dip" android:layout_marginRight="10dip" /> The text area looks fine, but the problem is that the cursor is blinking in the middle of the text field.
