I’m trying to confirm that a password contains at least one Capital Letter and One Number. The following search pattern works when it finds a number, but isn’t catching the lack of capital letter. Thanks for your Regex-pertise! rg.SearchPattern = "^(?=.*[A-Z])(?=.*\d).+$"

As @Greg_O alluded, the default setting for Xojo’s RegEx is case-insensitive. You can use his recommendation or put a switch directly into the pattern. (?-i)^(?=.*[A-Z]) ... Two things: your plan doesn’t ensure that there is a lowercase letter present so even when it’s working, “ABC123” would pass…

@Kem_Tekinay I think you nailed it!
