<p>I am unable to build my Web Application (not Web Site) in our build environement. We use DMAKE in our build environment (this unfortunately is non negotiable, therefore using MSBUILD is not permitted ) and when invoking the asp.net precompiler through</p>

<strong>error ASPPARSE: Could not load type '...'</strong></p>
<p>The problem was that we had the file on disk (on the project folder) but it wasn't included in our application project (in the .csproj file). We solved the problem by including the file in the project... | <p>I received the same problem. </p>
<p>I fixed it by copying my webapp's DLL from the OBJ/DEBUG folder to the BIN folder.</p>

<p>In my code attached below, I'm trying to upload a file via ASP.NET. I am dynamically creating the FileUpload control so that means it's not in my ViewState which (I think) means I can't use the control for uploading files unless I use the old fashioned multipat/form-data way which I don't want to do. I need to be ... | <p>You can use Request.Files</p>
<p>It contains the uploaded files as HttpPostedFile objects.</p>
<pre><code>foreach(HttpPostedFile file in Request.Files)
file.SaveAs(...);
</code></pre>
| <p>The problem is that the FileUpload control has locked off the FileName parameter from being set programmatically. The reason for this is to protect the user from some malicious script deciding that it wants to upload system files to the server instead of what the user wants.</p>

<p>I'm finally getting the hang of RSpec after spending a couple of hours over the weekend. Now I'm stuck trying to figure out how to assert that parameters are indeed passed into the controller. I'm following the <a href="http://blog.8thlight.com/articles/2008/04/20/bowled-over-by-rubycocoa" rel="nofollow noreferrer">... | <p>RubyCocoa is not supported at all on the iPhone. There is no bridge support library, and I do not believe there is any ruby interpreter on the phone.</p>

Though I'm not familiar with how Ruby/Cocoa wraps foreign method calls- or with Objective C for that matter- the first place that would seem likely to disconnect under test is passing in a Ruby mock to the natively implemented controller.

<p>I'm doing a basic homework assignment which looks like this:</p>
<pre><code> While input <> -1
input = CDbl(InputBox("Enter numbers to add, enter -1 to stop"))
values = values + input
End While

<p>It works fine until I press 'cancel' on the input box. Then the string inp... | <p>Try using Double.TryParse</p>
<pre><code>Dim value as Double = Nothing
If Double.TryParse(InputBox("Enter numbers..."), value) Then
values = values + value
End If
</code></pre>
<p>My syntax may be a bit off, but you should get the idea</p>
| <p>You'd also get an error if they entered anything other than a double or a value too big to be stored in a double.</p>
<p>The suggestions made should be enough though, you essentially want to validate the user input before you attempt to cast it.</p>

<h2>Question</h2>
<p>I'm sure many of you have been faced by the challenge of localizing a database backend to an application. If you've not then I'd be pretty confident in saying that the odds of you having to do so in the future is quite large. I'm talking anout storing multiple translations of texts (and the same c... | <p>I think you can stick with XML which allows for a cleaner design. I would go further and take advantage of the <code>xml:lang</code> attribute which <a href="http://www.opentag.com/xfaq_lang.htm" rel="nofollow noreferrer">is designed for this usage</a> :</p>

But nevertheless you can NOT fall back to English. With the XML approach you simply can fall back to English.

<p>I recently signed up to shared web hosting with godaddy using Linux and PHP 5. I want to work with multiple RSS feeds.

You will have to add that folder (and subfolders) to your include path so everything will be accessible.
It is considered as a bad practice because you will have to manually update PE... | <p>Your PEAR (or other libraries) classes can be anywhere. You just need to set correct include paths where script will search for required code. If you can't access php.ini, you can get include paths by using <code>get_include_path()</code> function and set them using <code>set_include_path();</code></p>
