selection

Been trying to solve this for weeks, but can't seem to get it. I have the following data frame : post_id user_id 1 post-1 user1 2 post-2 user2 3 comment-1 user1 4 comment-2 user3 5 comment-3 user4 6 post-3 user2 7 comment-4 user2 And want to create a new variable parent_id . So that for each observation it should perform the following steps: Check if post_id is either post or comment If post_id is post then parent_id should equal the earliest post_id of the whole data frame. If post_id is the first post then parent_id should equal NA If post_id is comment then parent_id should equal to the

I'm internationalizing an application into many different languages, and the following languages must be supported: English Spanish German French Russian Mandarin Chinese Thai We're also probably going to add support for: Hindi Portuguese Any other language people at work speak and can translate easily Should I install different fonts for each language, or should I go with one massive font installation of Arial Unicode MS?

I am writing a simple script for a Google Sheet. I have a button labeled "New Entry" (the button is actually a drawing with my script assigned to it). When the user clicks the button, the script inserts an empty row at a specified location and activates the first column so that the user can begin typing. Everything works great except that after the script finishes, the keyboard doesn't work until after the user manually clicks in the sheet. The correct cell is visibly activated, but I suspect the focus is still (secretly) on the drawing . This theory is supported by the fact that if the user

If I have the following HTML: <div class="content"> Vivamus <span>luctus</span> urna sed urna ultricies ac tempor dui sagittis. </div> And I run an event on mouseup that sees the ranges of the selected text: $(".content").on("mouseup", function () { var start = window.getSelection().baseOffset; var end = window.getSelection().focusOffset; if (start < end) { var start = window.getSelection().baseOffset; var end = window.getSelection().focusOffset; } else { var start = window.getSelection().focusOffset; var end = window.getSelection().baseOffset; } console.log(window.getSelection()); console.log

I'm setting the selection background color via CSS: ::selection { background:#cc0000; color:#fff; } ::-moz-selection { background:#cc0000; color:#fff; } On most browsers when the focus is somewhere else (like an IFrame), the selection color will stay the same, e.g.: but on Firefox it won't: You can see this in action on jsFiddle here . How can I get Firefox to set the selection color in this case? Is this a bug? How can I get Firefox to set the selection color in this case? Unfortunately, there doesn't appear to be a way to do so. Is this a bug? Nobody (including Mozilla themselves?) can say

When I use the RichTextBox.Select(int start, int length) function to select text in a rich text box that contains hyperlinks, there is some shift in the selection when I try to select any text that is after the hyperlink. When I remove the hyperlink, the selection works properly. Edit: I use RichTextBox 5 (the default in Visual Studio is version 4) public class RichText50W : RichTextBox { [DllImport("kernel32.dll", CharSet = CharSet.Auto)] static extern IntPtr LoadLibrary(string lpFileName); protected override CreateParams CreateParams { get { CreateParams prams = base.CreateParams; if
