alpha numeric data validation for excelI want to use a non vb formula in data validation for an excel formula
to make the user enter the first 2 characters of a field as UPPERCASE letters i.e. AB12345 - the format is always the same 2 letters 5 numbers. Any ideas? |

it does get rid of the volatile function calls (I wonder if that matter in a validation formula) Well, it leaves the formula vulnerable to row insertions and it accepts more than 7 characters. It appears that a formula with a volatile function used as a validation rule doesn't "act" volatile. In a test file I entered the validation rule using INDIRECT. Closed the file, opened the file, didn't do anything at all, then closed the file without Excel asking if I wanted to save changes ( a telltale sign that a volatile function is in use) We can shorten it by a few more keystrokes while at the same time adding a length test since a formula entered in a refedit is automatically processed as an array: =SUM(--(LEN(A2)=7),--(ABS(CODE(MID(A2,ROW($1:$2),1))-77.5)<=12.5),COUNT(-MID(A2,ROW($3:$7),1)))=8 So, as long as you don't insert new rows (in certain places) that looks pretty good. -- Biff Microsoft Excel MVP "Rick Rothstein" wrote in message ...

alpha numeric data validation for excelDoh... of course it needed a LEN test (can't believe I missed that).
So then, I guess INDIRECT is indirect only when used directly.<g Yes, using the automatic array process is definitely better. Of course, I tested my logic out on the grid directly and used SUMPRODUCT during testing to avoid hitting the Ctrl+Shift+Enter (just lazy on my part); then, because my wife wanted to use the computer, I rushed posting my findings without even thinking about the array processing part of it.

Closed the file, opened the file, didn't do anything at all, then closed the file without Excel asking if I wanted to save changes ( a telltale sign that a volatile function is in use) Any thoughts on that? Validation rules only apply when you enter something into cells with validation rules. If you're not entering anything, e.g., when saving files, then the validation rule wouldn't be evaluated. Key point: validation rules are OUTSIDE the calculation dependency tree. Validation permits initial entry, which in turn triggers minimal recalc, which also recalcs all formulas that call volatile functions, then evaluates the validation rule and takes appropriate action. In that context, custom validation formulas are ALWAYS volatile no matter what functions they call since validation rules are ALWAYS evaluated upon entry. Also, FWIW, if you select multiple cells, if the active cell doesn't contain a validation rule but other selectedd cells do contain validation rules, you could type anything you want in the active cell and press [Ctrl]+[Enter], and Excel will happily enter the active cell's value into all the cells without triggering validation in the other selected cells. IOW, validation rules are only evaluated for the active cell at the time of entry. And, as commonly known, validation isn't triggered by pasting into cells with validation rules. If the OP's users could be pasting values in from other programs (e.g., copying from PDF files), no validation rule will help. Only event handlers and validation formulas in other cells provide relatively robust validation. Excel's own Data Validation feature is an unreliable toy, as industrial strength (NOT!) as internal passwords. |
