Dashed or Dotted line in Photoshop

What will you do if you are asked to draw a dashed or dotted line in photoshop?

If you know the answer then its ok otherwise here's what I learnt. 
   I used to copy paste a rectangle shape again and again to draw a simple dashed line or a circle shape for a dotted line.  But then I got the solution.May be many of you know this but this one's for those who doesn't.

Simply Select a brush tool
Then Select the size of the brush as per your need. 
If you need a dotted line, use a round brush, if you need a dashed line, you have to load the Square Brushes library.
      To load the Square Brushes library, click on the brush size icon in the options bar, then click on the fly-out menu (that arrow icon as shown in the image) and select Square Brushes.

Then access the Brushes palette, click on the 'Brush Tip Shape'.  This will display all the settings, there you can change the Spacing setting to a high value (200 or more).  You will see the preview right there at the bottom of Brushes Palette. The Brush Palette will look like this:

Now you are done with the settings  you can a draw a dashed line, Hold on the SHIFT key and draw the line,  Shift key ensures a straight line.  I used this dashed line for one of many banners I designed.  You should try this.
