When you want to use the PeopleEditor control you need the correct refence in your custom SharePoint page.

<%
@Register TagPrefix="wssawc" Namespace="Microsoft.SharePoint.WebControls" Assembly="Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

Add a user to the picker (c#):

ArrayList list = new ArrayList();
list.Add(
    new PickerEntity()
    {
        Key = @"DOMAIN\User"
    }
);
userPicker.UpdateEntities(list);

Retrieve selected user(s)(c#):

PickerEntity pe = (PickerEntity)userPicker.Entities[0];
string username = pe.Key;
//or if the entities are resolved
PickerEntity pe = (PickerEntity)userPicker.ResolvedEntities[0];
string username = pe.Key;

that's it

It is very easy to add a breacrumb to your custom application page.

First of all you need to create an xml file in the
C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\LAYOUTS\ folder.

Rename this new xml file like this
layouts.sitemap.*.xml where you can change * to any string you want.

then change the content of the XML file like this
<?xml version="1.0" encoding="utf-8"?>
<siteMap>
<siteMapNode url="/_layouts/cutomapplicationpage.aspx"
parentUrl="/_layouts/settings.aspx" title="Custom Application Page"/>
</siteMap>

finally use
STSADM -o copyappbincontent

</tom>

Ton Stegeman [MVP] wrote a wonderful article about how to create a custom sharepoint page.

However, when you are searching for the hidden

Microsoft.SharePoint.ApplicationPages.WebAdminPageBase assemby

stop searching!

It is NOT in the sharepoint.dll. You must add a new reference to the Microsoft.SharePoint.ApplicationPages.dll. You can find this dll here:

C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\CONFIG\BIN\Microsoft.SharePoint.ApplicationPages.dll

nice to know not?
