PackageManagement\Install-Package : No match was found…

As ever, creating this note as a reminder and to save me trawling Google the next time the problem occurs.

When attempting to install a PowerShell module and the following error happens…

PackageManagement\Install-Package : No match was found for the specified search criteria and module name 'AzureAD'. Try Get-PSRepository to see all available registered module repositories.
At C:\Program Files\WindowsPowerShell\Modules\PowerShellGet\1.0.0.1\PSModule.psm1:1809 char:21

… it can be resolved by running this command.

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

Invoke-SqlCommand

For whatever reason, sometimes you just can’t upgrade the installed version of PowerShell on a server. In this case, I wanted to make use of the Invoke-SqlCommand command.

The most simple way around this limitation is to add a module to the server that includes a command that performs the same function.

Jourdan Templeto’s Simple SQL in PowerShell post has a cmdlet that can be cut and pasted into a new PowerShell module file and then easily accessed from your own scripts. Simple.

Semantic method naming

An old post – but still relevant – about semantically naming methods within code.

Value does not fall within the expected range

The following code, which was supposed to update the “Current” Composed Look, was throwing a “value does not fall within the expected range” error each time I ran it.

SPWeb web = properties.Feature.Parent as SPWeb;
SPList gallery = web.GetCatalog(SPListTemplateType.DesignCatalog);

if (gallery != null)
{
    SPQuery q = new SPQuery();
    q.RowLimit = 1;
    q.Query = "<Where><Eq><FieldRef Name='DisplayOrder'/><Value Type='Number'>0</Value></Eq></Where>";
    q.ViewFields = "<FieldRef Name='DisplayOrder'/>";
    q.ViewFieldsOnly = true;

    SPListItemCollection items = gallery.GetItems(q);

    foreach (SPListItem item in items)
    {
        item["MasterPageUrl"] = web.MasterUrl;
        item.Update();
    }

}

After a lot of head scratching, it boiled down to the ViewFieldsOnly property which, which I had left set to true. Doh! Updating the property to false corrected the error.

See: SPQuery.ViewFieldsOnly property

Oops! Twitter Feeds Now Working

I missed the June announcement from Twitter informing everyone that their API v1 was about to be retired – meaning that feeds on my homepage had been failing to update.

Along with the introduction of rate limits and ditching support for RSS as a response format, API v1.1 has implemented OAuth 2.0 for its authentication. Its not the most straight-forward thing to get your head around, but I found a useful post on CodeForest that helped me to update my own WordPress widgets.

CSS and Nested Border-Radii

Now, this is an issue I’ve stumbled across while putting together CSS for websites.

You have two elements, one nested within the other, and both have rounded borders. Unless you get the radius of the nested element just right, you’ll end up with a nasty looking ‘hump’ where there should be a nice smooth curve (See Chris Coyier’s post for a visual example).

Fortunately, Joshua Hibbert has blogged about the problem, documented the math­em­at­ical for­mu­las and even coded a tool for the job. Great!

Hiding SharePoint WebParts via Code

Another note to myself…

When wanting to programmatically hide a WebPart, don’t try to set it’s Visible property to False. This will cause you lots of trouble and create errrors. The correct method is to set its Hidden property to True.

if (items.Count == 0)
{
   this.Hidden = true;
   return;
}
