How do I round some corners of a shape and leave other corners unrounded ?

Question

Hello All;
Could someone tell me how to round some corners of a illustration and leave some corners unrounded ? If I use Effect - Stylize - Round Corners, it works beautifully but it rounds all corners, even the ones I don't want rounded. See attached illustration. I do not want the four corners emclosed in the circle rounded.
Anyone know how to do this (easily, I hope) ?
Thanks.
Tim

Tim,
That's a good one. What you can do is:
Make two rounded rectangles with the dimensions you require, and stack them on top of each other.
Go to the align palette and click the icon that centers the objects vertically.
From your attached illustration, it seems you want to avoid rounding the line segment in the middle top and bottom of each rectangle, so try this:
With the pen P tool, put the point of the pen on the first of (4)four anchor points you are going to add and click.
Now do the same thing for the other three anchor points.
You have now added two anchor points to each rounded rectangle
With the Direct Selection A tool, Shift/click on both of the furthest right anchor points you just created, and hold shift while clicking the corner radiuses that connect with those points on the right side of the illustration. You should have a total of six points highlighted altogether.
Now with your keyboard cursor controls, click the arrow down key as many times as you need to get the angle of the line segment that you were trying not to round.
If there is another way to do it, I'd like to know, but that should work. The corner rediuses you've moved change somewhat, you can adjust them if need be.
Using the grid and snap to point in the View section of the menu bar will help you align the added anchor points nicely.
Sounds like a lot, but I recreated your drawing the way you wanted in about 30 seconds.
Hope this helps.
