title: Programmatically open a new tab in ie7
body: <p>I am developing web applications with c#, Aspnet 3.5, and Ajax 2.0. </p>
  
  <p>Question - I run Application_1 in ie7. I would like to programmatically start running Application_2 from Application_1 in a new tab, no matter what the client settings are.   </p>
  
  <p>Until now I have been opening Application_2 in  a new window from Application_1 using </p>
  
  <pre><code>ScriptManager.RegisterStartupScript(this, typeof(Page), UniqueID, "window.open('theurl',' width=800, height=500'); ", true);
  </code></pre>
  
  <p>I would like to do something similar to open a new tab.</p>
