Understanding QuickWatch

Keyboard:  SHIFT + F9

In vstipTool0104 (https://blogs.msdn.com/b/zainnab/archive/2010/10/08/the-watch-window-watching-and-changing-values-vstiptool0104.aspx) I showed you the QuickWatch as a way to get watches into a Watch window.  From that perspective, they are rather slow and cumbersome.  However, QuickWatch doesn't just exist for that reason so another look might be worth it:

Why QuickWatch?

So, why does QuickWatch exist?  Well, it was actually created to be a dialog that is a one-stop shop for quickly working with expressions.  Think of it as a dialog dedicated to a single watch.  It's a modal dialog so you need to close it before moving on with any other debugging. 

 

 

What does it do?

Like a normal watch, you can edit the value in it:

You can change the expression and click the "Reevaluate" button to see a new value:

One big advantage to the QuickWatch window is the fact that it can be resized.  It can be very useful when digging deep into a single item:

Other Options

While it is useful for specific scenarios, with the advent of DataTips the usefulness of QuickWatch has diminished:

    When using VS 2010 to debug JavaScript code, in QuickWatch how can I edit the value of a string var when the string value contains one or more double-quote characters? QW keeps refusing my edits, until I delete the double-quote chars (but my value needs them).  My character escape attempts have all failed. Thanks.
