Anyone know of a nifty VB command that will tell you the number or times a string appears within another string?

For example, let's say we have a string that will be placed in a txtBox where .multiline=True. It'd be nice to know how many CrLfs are in the string so you can determine the # of lines to be displayed.

It's easy enough to write code to do this, but maybe VB does it for me. Thanks...
