3,767,285 | 3,767,286 | C# how to sort a list without implementing IComparable manually? | <p>I have a fairly complex scenario and I need to ensure items I have in a list are sorted. </p>
<p>Firstly the items in the list are based on a struct that contains a sub struct. </p>
<p>For example:</p>
<pre><code>public struct topLevelItem
{
public custStruct subLevelItem;
}
public struct custStruct
{
public string DeliveryTime;
}
</code></pre>
<p>Now I have a list comprised of topLevelItems for example:</p>
<pre><code>var items = new List<topLevelItem>();
</code></pre>
<p>I need a way to sort on the DeliveryTime ASC. What also adds to the complexity is that the DeliveryTime field is a string. Since these structs are part of a reusable API, I can't modify that field to a DateTime, neither can I implement IComparable in the topLevelItem class. </p>
<p>Any ideas how this can be done?</p>
<p>Thank you</p>

<pre><code>OnClientClick="jpcPrint(<%= this.Controller.JPId %>);"
</code></pre>
<p>for a button, <%= this.Controller.JPId %> is literally put into the html rather than being evaluated. How do i write some version of the above such that the html would read:</p>
<pre><code>onclick="jpcPrint(49);"
</code></pre>
<p>for example instead of </p>
<pre><code>onclick="jpcPrint(<%= this.Controller.JPId %>);"
</code></pre>
<p><%= this.Controller.JPId %> evaluates perfectly well when placed elsewhere on the page including in a gridview above this button. For example this works fine:</p>
<pre><code><cc1:AutoCompleteExtender ID="Autocompleteextender1" MinimumPrefixLength="4" CompletionInterval="1000"
CompletionSetCount="10" ServiceMethod="GetCompletionList" ContextKey="<%# this.Controller.JPId %>"
TargetControlID="txtLKey" runat="server" CompletionListCssClass="jpcKeyList" >
</code></pre>
<p>So this.Controller.JPId is not the issue. Seems to be something about the way such statement are evaluated within button attributes.</p>

1,175,433 | 1,175,434 | Distribution of Android application | <p>I'm in the process of researching if and how an entrerprise Windows Mobile .NET application can be ported to Android. The question that I'm into right now is how to distribute and update the application once it's developed.</p>
<p>The current .NET application is "installed" on a device using an approperiate system image. The program then updates itself by downloading new updates from a website during usage and installing those updates on the next startup. So now the question is, how is this task best performed with an android application? I've received indication that the company would like to get away from using images so that more devices can be supported, so using images is not a requirement. However, it is an internal enterprise application and as such no external users are to be able to download it, so simply putting it on android market for anyone to download is not an option.
Does anybody know if there is an "easy" solution to this problem in the Android world?</p>

<p>It does the job but does not look very clean to me. Is there some way I could make this code a bit smaller. I was thinking to just have the number 14 or 18 as a variable but I am not sure the best way to code if I should use if-else or some other way.</p>

<a href="http://stackoverflow.com/questions/498970/how-do-i-trim-a-string-in-javascript">How do I trim a string in javascript?</a> </p>
</blockquote>
<p>While I solved the issue I was experiencing when I was looking for a solution a few moments ago I was not able to find anything that actually worked. This is mostly intended to be an easy-to-find question/answer for others to find as I am surprised by the lack of the absence any on-topic pages on the WWW in general.</p>
<p>So <strong><em>using JavaScript without any frameworks how would you trim line breaks</em></strong>? Trim as being defined by PHP, removing the leading and ending line breaks while preserving line breaks after the first non-white-space character and until though not beyond the last non-white-space character.</p>
<p>By default most people will want to know how to <strong><em>remove both leading/ending line breaks as well as white-space spaces too</em></strong> though some may want to retain the white-space spaces while trimming just the white-space line-breaks. It also generally helps to see two working examples and how they relate when they both work for people learning code so I'll accept the answer for trimming both white-space line-breaks <em>and</em> white-space spaces while voting up how to trim just the leading/ending line breaks while preserving white-space spaces (which may or may not be included in the main answer).</p>
