Making an email label a hyperlink

阅读更多关于 Making an email label a hyperlink

问题 I was wondering if it is possible to make a label a hyperlink? Below is the code for a column I have set up and I want to make "lblEmail" clickable so that the email opens up and with that email address in it. The idea is that as various users log in to the site, their unique info will appear in the column. Is it as simple as wrapping the label control in an anchor tag? If so, I must be missing something because I tried that. Since I am new, it is likely I missed something! Thanks in advance!

How to configure the scale label position in ILNumerics?

阅读更多关于 How to configure the scale label position in ILNumerics?

问题 I draw some lines with ILLinePlot. Then I rotate the cube (with the intention to change the position of the Y scale label that starts from the top): Rotation = Matrix4.Rotation(new Vector3(1, 0, 0), ILMath.pif), It produces results like this. In this graph, I am losing the scale label in Y axis. How to configure it? So the label can be shown? Update: This question is related to : How to reverse the axis in ILNumerics At first, I have make a graph that consists some lines like this figure:

Select text and copy from label xamarin forms

阅读更多关于 Select text and copy from label xamarin forms

问题 I have for some days been reading on different forums about the issue of selecting a text and copying the text natively from a label in xamarin forms and it seems to be no straightforward way of implementing this. My problem is that I need to present a large amount of data from a book in a label and the user should be able to select and copy a chunk of text from the label. I moved on to present the data in an Editor component instead but then the user can edit the text in the Editor. Making

问题 For the past hours I have tried to understand the whole design/theme/labelling concept around ggalluvial , but I failed. Within minutes I was able to produce the kind of graph I want (thanks to the package ggalluvial), but I can't figure how to produce the correct labelling/theme I'd like to have. This is where I am currently: This is where I was initially: To get you to understand where I am, here's a reproducible example I used the following code: library(ggalluvial) ds <- as.data.frame

Can I have multiple colors in a gnuplot label?

阅读更多关于 Can I have multiple colors in a gnuplot label?

问题 I have this graph in gnuplot: I want to include totals for each of the three colored line graphs. One possibility is to replace the key with this: Can I plot this with a single label that switches colors? If not then I'd have to use six labels. In that case, how do I determine the coordinates of the labels given that the widths of the strings can vary? I could use a fixed width font and do some computation based on the number of digits in each of the totals but this seems tedious. Is there a

问题 I'm aware that this question has appeared in various forms before, but none of the solutions worked out for me... I'm using the Titanium API 2.1.3, and building for iPhone. I use a lot of common JS, so I have this: exports.Header = function(title){ var l = Ti.UI.createLabel({ text: title, height: 'auto', textAlign: 'left', color: '#989898', font: {fontSize: exports.defaultFontSize+10, fontFamily: exports.defaultFont, fontWeight: 'bold'} }); return l; }; And I'm calling the label like so: var

Is it possible to simulate HTML tag <Label /> in asp:Label ASP.NET Control?

阅读更多关于 Is it possible to simulate HTML tag in asp:Label ASP.NET Control?

问题 I really like the HTML tag which makes it really easy to see which label stands for which input element by checking its 'for' attribute. You know, something like: <label for="txtInput"> Enter your name</label> <input type="text" id="txtInput" /> Is it possible to do something similar in asp.net Label control so that I can see it stands for what input control? I could not see an attribute for that. Without extending the control? Thanks! 回答1: http://msdn.microsoft.com/en-us/library/system.web

ML----KNN算法----Spark实现

阅读更多关于 ML----KNN算法----Spark实现

KNN算法思想 KNN（k-NearestNeighbor）又被称为最近邻算法，它的核心思想是：物以类聚，人以群分。KNN算法是机器学习中最简单的方法之一。所谓K最近邻，就是k个最近的邻居的意思，说的是每个样本都可以用它最接近的k个邻居来代表。KNN是一种分类算法，KNN没有显式的学习过程，也就是说没有训练阶段，待收到新样本后直接进行处理。 KNN的思路是：如果一个样本在特征空间中的k个最邻近的样本中的大多数属于某一个类别，则该样本也划分为这个类别。KNN算法中，所选择的邻居都是已经正确分类的对象。该方法在定类决策上只依据最邻近的一个或者几个样本的类别来决定待分样本所属的类别。提到KNN，网上最常见的就是下面这个图，可以帮助大家理解。我们要确定绿点属于哪个颜色（红色或者蓝色），要做的就是选出距离目标点距离最近的k个点，看这k个点的大多数颜色是什么颜色。当k取3的时候，我们可以看出距离最近的三个，分别是红色、红色、蓝色，因此判定目标点为红色。 KNN算法描述 1）分别读取测试数据、训练数据集； 2）计算测试数据与训练数据之间的距离； 3）选取距离最小的K个点； 4）确定前K个点所在类别的出现频率； 5）返回前K个点中出现频率最高的类别作为测试数据的预测分类 Spark实现 /** * 数据集：鸢尾花数据集 * * Iris 鸢尾花数据集是一个经典数据集
