Enumerating All SPWebs In SPFarm.Local Into Strongly Typed Collection

So when enumerating the SPWebs within a SPFarm to build a strongly typed SPWeb collection for whatever purpose your enumeration might look like this:

[csharp]

public static List WebsPreppedForIteration()
{
var collection = new List();
foreach (SPSite x in SPFarm.Local.Services.OfType().SelectMany
(svc => ((svc).WebApplications.Where
(webApp => !webApp.Properties.ContainsKey(“Microsoft.Office.Server.SharedResourceProvider”)).SelectMany
(webApp => webApp.Sites.Cast()))).Where
(x => !Equals(x.RootWeb.Title, “Central Administration”)))
{
collection.AddRange(x.RootWeb.Webs.Cast());
}
return collection;
}

[/csharp]

I saw this in a code review today. The part I am wondering about is the SPWebApplication property bag to query the key for WCAM as opposed to do a clunky string SPWeb.Title comparison. Putting the keys out to standard output hasn’t yielded anything particularly evident, and I’m getting frustrated with the under-the-hood, unnecessary foreach loop with a fancy shirt on (the second LINQ query against the Title property(,

Does anyone know the key for WCAM?

Returning The SharePoint Start Workflow Link

Building the “Start Workflow” link is pretty straight forward. I am pretty sure there are better ways to do it, but here is an approach when you have to build the link using a string return. How it works is pretty straightforward. Consuming a SPListItem and SPWorkflowAssociation parameter, the SPListItem exposes the ParentList and ID properties and the SPWorkflowAssociation provides the InstantiationUrl and Id properties. The only field level stuff is I was passing a finish url in the query string (_finalurl in the below). When the link is built, it is cleaned up using the inherent SPHttpUtility.UrlKeyValueEncode method.

[csharp]
private string _finalurl;

public static string QueryStringAppend(string url, string args)
{
if (string.IsNullOrEmpty(url))
{
return url;
}
var num = url.LastIndexOf(“?”);
switch (num)
{
case -1:
return (string.Format(“{0}?{1}”, url, args));
}
return num == (url.Length – 1) ? url + args : string.Format(“{0}&{1}”, url, args);
}

protected string BuildWorkflowStartLink(SPListItem listItem, SPWorkflowAssociation workflowAssociation)
{
var builder = new StringBuilder();
builder.Append(SPHttpUtility.UrlPathEncode(string.Format(“{0}/{1}”, Web.Url, workflowAssociation.InstantiationUrl), true));
builder.Append(“?List=”);
builder.Append(listItem.ParentList.ID.ToString());
builder.Append(“&ID=”);
builder.Append(listItem.ID.ToString());
builder.Append(“&TemplateID=”);
builder.Append(workflowAssociation.Id.ToString(“B”));
string url = _finalurl ?? Request.QueryString[“Source”];
url = QueryStringAppend(url, string.Format(“{0}={1}”, FinishIdName ?? “ID”, listItem.ID));
if (!string.IsNullOrEmpty(url))
{
builder.Append(“&Source=”);
builder.Append(SPHttpUtility.UrlKeyValueEncode(url));
}
return builder.ToString();
}
[/csharp]

Chaining SharePoint Builds Status

So I am still in migration hell and fixing some build code. One of the problems we just ran into was chaining build events. Consider if you had SharePoint project X which contained and Exec command that triggered SharePoint project Y. The goal of their custom build is to query into the build status of SharePoint project Y, and display the build status in SharePoint project X’s build status. Put simply, I needed a mechanism where Project Y build status, like whether it returns Success, Partial Success, etc.

Fortunately, this isn’t terribly difficult using the Exec task to execute a command leveraging the exitcode to get the status. This looks like the following:

[xml]






[/xml]

The exitcode return will be an integer, which is easy to correlate to the respective return values, Failure is 100, Partial Success is 1, Success is 0, Unknown is -1, and Unrecognized Command is 2.
