<p>I get the warning "childNodes is null or not an object' with different line numbers, depending on which version of the library I reference (I've tried about three different versions of 1.2.6). Consequently, I get jack for jQuery intellisense.</p>
<p>I can hack this to get it to work, but I'd rather not as I don't ... | <p>I ran into this same issue a little while back. Are you using the jQuery UI files as well? I was and it turned out that the jquery ui javascript file was messing up the intellisense somehow. So I created an empty vsdoc.js file for the jquery ui file and then intellisense started working. My jquery ui file was called... | <p>It does work for me;
Not sure why it is an error for me and why the fix is needed?</p>

<p>I am trying to mock-up an API and am using separate apps within Django to represent different web services. I would like App A to take in a link that corresponds to App B and parse the <code>json</code> response. </p>
<p>Is there a way to dynamically construct the url to App B so that I can test the code in develop... | <p>You can try <a href="http://danbunea.blogspot.com/2005/11/model-view-presenter-is-testing_27.html" rel="noreferrer">MVP</a> if you want to put the logic of the UI in a separate class..</p>
<p>In model view presenter just as Martin Fowler or Michael Feathers say, the logic of the UI is separated into a class called ... | <p>I would only put UI logic in the Form class and put any application logic in its own class:</p>
<pre><code>class Form1 : Form
{
void Button1_Click
{
Program.DoCommand1();
}
}
static class Program
{
internal static void DoCommand1() {/* ... */}
}

<p>I am just curious to know how long, in minutes, does the reporting service take to generate report when it returns 1MB of data. Maybe using views and table is properly index. SSRS reporting and server side generation.</p>
| <p>Report generation time has two components:
- Data Acquisition time
- Render Time</p>
<p>So for 1 Mb of data, how many records (rows) are we talking? How many pages will the report have? How many controls per page? Does the report use charting? These are the factors that will determine generation time. </p>
... | <p>I've found, when using BIRT and other reporting systems that the best improvements tend to come by offloading most of the work to the database at the back end.</p>
<p>In other words, don't send lots of data across the wire and sort or group it locally. The database is almost certainly going to outperform you with ... | 15,956 |
<p>I'm trying to create a TCP connection and send/read data that uses SSL, but I haven't been able to successfully accomplish this.</p>

I've used it for wrapping existing TCP connections in the past.</p>
