highlighting part of string?

[Ouka]

Hi all,

I have a comma deliniated textbox value error checker

i.e. my procedure checks that all comma delinated values in a userform textbox control are valid. If not, a message box comes up informing the user of the invalid entry and the procedure is exited.

I would like to have only the invalid text within the textbox highlighted. Is this possible? If so, how would it be done?
