<p>I want to filter the selectable dates on a datepicker. I basically need to filter by work days - i.e. make holidays and weekends not selectable.</p>

<h3>Original Post</h3>
<p>As Tundey pointed out in <a href="https://stackoverflow.com/question... | <p>I finally came up with a Form subclass that solves this, once and for all. To use it:</p>
<ol>
<li>Inherit from RestorableForm instead of Form.</li>
<li>Add a binding in (ApplicationSettings) -> (PropertyBinding) to WindowRestoreState.</li>
<li>Call Properties.Settings.Default.Save() when the window is about to clo... | <p>Well I have had a quick play with this and you are correct, while there is no way to directly <em>bind</em> the size of the form to AppSettings, you can add your own values and change the size on load.</p>

<p>I need to change the app name based on what configuration I'm using in Visual Studio. For example, if I'm in Debug configuration, I want the app name to show as 'App_Debug' in the Application field in the Elmah_Error table. Does anyone have any experience with this? Or is there another way to do it?</p>
| <p>This can now be done purely in markup. Just add an <code>applicationName</code> attribute to the <code>errorLog</code> element in the <code><elmah></code> section of the web.config file. Example:</p>
<pre><code><errorLog type="Elmah.SqlErrorLog, Elmah"
connectionStringName="connectionString" applicati... | <p>By default, Elmah uses the AppPool's application GUID as the default application name. It uses this as the key to identify the errors in the Elmah_Error table when you look at the web interface that's created through it's HTTP Module. </p>

<p>I want my Ruby program to do different things on a Mac than on Windows. How can I find out on which system my program is running?</p>

<p>I'm checking for existing of a row in in_fmd, and the ISBN I look up can be the ISBN parameter, or another ISBN in a cross-number table that may or may not have a row.</p>

<p>I'm having issues with color matching css background colors with colors in images on the same html page. What gives?</p>

<p>I want to create a bundle from an arbitrary bundle identifier<br>
e.g. <code>com.apple.iokit.IOStorageFamily</code> </p>
<p>It's not an unreasonable thing to do as bundle IDs are supposed<br>
to be unique, however the obvious code does not work:</p>
<pre><code>NSString* bID = @"com.apple.iokit.IOStorageFamily";
N... | <p>Use this</p>
<pre><code>NSString *path = [[NSWorkspace sharedWorkspace] absolutePathForAppBundleWithIdentifier:@"com.apple.TextEdit"];
</code></pre>
| <p>If what you're looking for is definitely a kext, then you could look at the info dictionary for each bundle in the /S/L/Es/ folder until you find yours. There's no search for bundle by identifier apart from for Applications (where LaunchServices will do it), and loaded bundles as you've already found.</p>
