trouble with some regular expression pattern matching

[Peted]

Hi,

im having some trouble with reg expression pattern matching for
something i think should be a straightforward test.
Im validating the text being entered in a winforms textbox and i need
to bring up a message in a validation test if these patterns are found
in the text enetered in the text box.
specifcially this combination --- {:}
or

this combination -- <anychar{ <anychar } <anychar>

so it will detect any text input where an open left braces and closed
right braces any where in the string in the above orientation. Is just
one brace of either type is entered it should NOT be detected.
Cany anyone help or point me in the right direction for the correct
regex pattern matching.
i was thinking "*{*}*" should work.

And extactly what are these "{ }" bracket types called are they
braces ? or brackets and what is there enum identifier in the c# Keys
keydata enums ?

thanks for any help
