I did not create the selectsite.aspx page that I'm calling, it is part of SharePoint. I want to be able to call the page to select a site collection and return the url. Similar to the way that the SharePointiteAdministrationSelector calls it when you are changing site collections. So to answer your question, I don't know how the return value is passed back, that is what I'm trying to figure out.
This worked for me. Thank you for your earlier replies.
commonShowModalDialog("/_admin/SelectSite.aspx?mode=NonRedirected&SiteID=617309a5-74ef-4c2d-9498-deb9b5b00228","resizable: yes; status:no; scroll: no; help: no; center: yes; dialogwidth:640pt; dialogHeight:400pt;",RetrieveValue); return false;
