Just so you know. The ampersand is typically used for underlining the letter that follows to make an Accelerator Key. By this, if you put &Cancel on a button's caption then it would appear like this: Cancel.
Rather than click the button you now have a keyboard shortcut for your button: by pressing Alt + C
I know I'm resurrecting an old thread here, but this post was the top result in my Google search on this issue.
If you're trying to use the "&" symbol within a string (like AT&T for example), you would set the Caption value to "AT&&T" (without the quotes), as the posters above have described.
However, if you want the label to just have the & symbol in it, you need to set the Caption value to "&&&" (without the quotes). For some reason, it looks like you need an extra ampersand in that instance. If anyone else out there is searching for this issue like I was, try this out and see if it works for you.
Looks like it only took 13 years for someone to find the solution for this.
