<p>I'm planning to develop an app for the iPhone and that app would have to access a couple of SOAP services.

<p>I'm running MAMP 1.7.2 on a Mac and I'd like to install the extension php_gd2. How do I do this? I know that on Windows using WAMP I'd simply select the <code>php_gd2</code> entry in the extensions menu to activate it. How is it done when using MAMP? I know that I can do it using MacPorts but I'd prefer not to ma... | <p>You shouldn't need to install the extension. I have 1.7.2 installed and running right now and it has GD bundled (2.0.34 compatible).</p>
<p>From the MAMP start page, click on phpinfo and you should see a GD section.</p>
| <p>php.ini for MAMP 1.7.2 is located:
if using <strong>php5</strong>, here: <strong>/Applications/MAMP/conf/php5/php.ini</strong>
if <strong>php4</strong>, here: <strong>/Applications/MAMP/conf/php4/php.ini</strong></p>
<p>hope that helps...</p>

<p>Some people have figured out how to take raw LiDAR data and after going through multiple steps (using LAS tools, converting to digital elevation model (DEM), converting to an STL) getting an STL file that they can then slice and print.</p>

<p>I want to handle different types of docs the same way in my application
Therefore:
I have a generic interface like this.</p>
<pre><code>public interface IDocHandler<T>where T: class

<p>I am attempting to programmatically monitor the size of a SQL Server database, so that my admin section of my web app can report it, and I can use that to execute some cleanup SPs, to clear log files, etc.</p>
<p>I use the following code to calculate the size of the tables, per SO recommendation:</p>

<p>Everything was going well. Nightly builds ran for more than a month with no problems. However, suddenly when invoking the feature builder from Eclipse the execution ends right away with the message.</p>
