title: Can't place a control on a form in Visual Studio
body: <p>I'm a newbie with Visual Studio Express 2013 and C#.  I've borrowed a simple C# Windows application which builds and runs fine, and now I want to add some objects to the main form.</p>
  
  <p>I select an object from the Toolbox, then click in the Designer on my main form where I want it to appear.  This works fine for some simple objects like Label, but when I select an OpenFileDialog object nothing appears on my form.  An OpenFileDialog "box" appears in a bar below my form instead, and I can't drag it to my form (I get a slashed circle).</p>
  
  <p>I'm surely missing something simple.  Thanks for any help.</p>
