title: Time Delay for operations using WinForm App in c#
body: <p>I have a problem with a Windows Form Application in C#
  Inside This application there is a Tabbed Browser. Now i want that in a loop (where i do some operation to calculate the next url) i could add a delay between AddTab. </p>
  
  <p>I.E </p>
  
  <pre><code> foreach(Urls url in Links){
  
          // Do something with url
           if(url.Host == "google"){ //if host is google until start the 
                                     // next AddTab i would wait 5 SEC
               addTab(url);
             //Here i Tried to use Sleep Thread , While(TimeCur-TimePre) {} but i always 
             // get Freezing and the other Tabs dont continue the loading
               Wait 5 Seconds in somehow
           }
  }
  </code></pre>
  
  <p>As i wrote i dont want use Thread Sleep becouse it freezes My Form Application. I already used the time trick with TimeCur-TimeSaved+(x Second) but this freezes the form too.</p>
  
  <p>I saw many topics where people say to use Timers so I tried to use them(without any result, maybe i wrong something)</p>
  
  <p>What can i add in this loop to delay the opening between the AddTab without freezing anything?</p>
