<p>Within our Active Directory domain, we have a MS SQL 2005 server, and a SharePoint (MOSS 3.0 I believe) server. Both authenticate against our LDAP server. Would like to allow these authenticated SharePoint visitors to see some of the data from the MS SQL database. Primary challenge is authentication.</p>

<p>Do you mean that they want to see data from inside a SharePoint page?
In that case you have to do impersonation in that page/application, and possible set up Kerberos correctly.</p>

<p>Has anyone used jQuery to populate an autocomplete list on a textbox using ASP.NET webforms? If so, can anyone recommend a good method?

<p>I don't want customers to be able to make backups of my sql server database and access the tables data etc.</p>

<p>Ok, do you do <code>Business.Name</code> or <code>Business.BusinessName</code>
<code>SubCategory.ID</code> or <code>SubCategory.SubCategoryID</code></p>
<p>What about in your database?</p>
<p>Why?</p>
<p>I'm torn with both. Would love there to be a "right answer"</p>
| <p>The only "right" answer is to be consistent. Decide upfront which one you will be using in a project, and stick to it.</p>
| <p>For very common properties like "Name" and "ID", the convention I have used is to not put the entity name in the field. For more unusual properties, I do put the entity name.</p>

<p>I would like to be able to manipulate the DOM just before my page is sent to be printed.

<p>Like:</p>
<pre><code>function myPrint() {
$("#myDiv").css({"border-color":"red"});
window.print();
}
</code></pre>
<p>Then you could call it from where you need it.</p>

<p>It may not be best practice but are there ways of removing unsused classes from a third party's jar files. Something that looks at the way in which my classes are using the library and does some kind of coverage analysis, then spits out another jar with all of the untouched classes removed.</p>

<p>The JarJar project does this AFAIR. The first goal of the JarJar project is to allow one to embed third party libraries in your own jar, changing the package structure if necessary. Doing so it can strip out the classes that are not needed.</p>
