multiline

I have a Multiline richtextbox control into which i want to integrate the feature of adding a line number. i have considered many approaches Add a label and updating the line numbers as the line count changes Add a picturebox along with to draw string on it. Add another textbox along with and show line numbers on it Add listbox along and display line numbers in it. I got two doubts. The richtextbox which i'm using is a custom made control and derieves from RichTextBox class. How can i add multiple controls to it. What is the best approach to show line numbers for the multiline text in c# My

I have a quite big XML output from an application. I need to process it with my program and then feed it back to the original program. There are pieces in this XML which needs to be filled out our replaced. The interesting part looks like this: <sys:customtag sys:sid="1" sys:type="Processtart" /> <sys:tag>value</sys:tag> here are some other tags <sys:tag>value</sys.tag> <sys:customtag sys:sid="1" sys:type="Procesend" /> and the document contains several pieces like this. I need to get all XML pieces inside these tags to be able to make modifications on it. I wrote a regular expression to get

There are a lot of similiar questions over internet, on SO included, but proposed solutions doesn't work in my case. Scenario : there is a log textbox in xaml <TextBox Name="Status" Margin="5" Grid.Column="1" Grid.Row="5" HorizontalAlignment="Left" VerticalAlignment="Top" Width="600" Height="310"/> There are methods in code-behind that do some work and add some multiline (maybe that's the problem?) messages into this textbox: private static void DoSomeThings(TextBox textBox) { // do work textBox.AppendText("Work finished\r\n"); // better way than Text += according to msdn // do more textBox

The Story: When a list of strings is defined on multiple lines, it is often easy to forget a comma between list items, like in this example case: test = [ "item1" "item2" ] The list test would now have a single item "item1item2" . Quite often the problem appears after rearranging the items in a list. Sample Stack Overflow questions having this issue: Why do I get a KeyError? Python - Syntax error on colon in list The Question: Is there a way to, preferably using static code analysis , issue a warning in cases like this in order to spot the problem as early as possible?

Background: I have a custom generated log file that has the following pattern : [2014-03-02 17:34:20] - 127.0.0.1|ERROR| E:\xampp\htdocs\test.php|123|subject|The error message goes here ; array ( 'create' => array ( 'key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3' ), ) [2014-03-02 17:34:20] - 127.0.0.1|DEBUG| flush_multi_line The second entry [2014-03-02 17:34:20] - 127.0.0.1|DEBUG| flush_multi_line Is a dummy line, just to let logstash know that the multi line event is over, this line is dropped later on. My config file is the following : input { stdin{} } filter{ multiline{ pattern

Whats the most efficient way of removing a 'newline' from a std::string? #include <algorithm> #include <string> std::string str; str.erase(std::remove(str.begin(), str.end(), '\n'), str.end()); The behavior of std::remove may not quite be what you'd expect. See an explanation of it here . If the newline is expected to be at the end of the string, then: if (!s.empty() && s[s.length()-1] == '\n') { s.erase(s.length()-1); } If the string can contain many newlines anywhere in the string: std::string::size_type i = 0; while (i < s.length()) { i = s.find('\n', i); if (i == std::string:npos) { break;

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. SV. I finally found it.. No need to download and load any external macro. Its working in Visual Studio 2008 with in-built macro at least. :) Steps : 1
