Hello David,

Thanks goes out to Tom, again. You noticed to expected behavior of
recursion with Excel VBA. Note: Your solution requires a call to a function
which returns the desired string value or a error message. Thus the calling
function can then drive require loop until a valid date is entered.

| Hello,
| I have a problem...
| I call my proc inside itself and here's what happens...
|
| for example :
| ****
| Sub test()
|
| Dim MyYear as Variant
| Dim AnyString as String
|
| MyYear = Inputbox("type your date (yyyy)")
|
| Select Case MyYear
| Case 1900 to 2000
| AnyString = "20th Century"
| Case 2001 to 2050
| AnyString = "Begining of 21Th Century"
| Case else
| AnyThing = "This is not a valid Date"
| ' I'M HERE RECALLING THE SAME SUB SO I CAN HAVE THE INPUTBOX
AGAIN
| call test ' (or just test)
| End Select
|
| Msgbox AnyString
| End sub
| ****
|
| Unfortunatly... if i run my modules and for several time put something
| else
| than a number to my inputbox, it will run my inputbox several time but
| ALSO
| would run the MSGBOX ANYSTRING as much as time... so i have onr right
| message and several-1 not as good !!
|
| Can anyone tell me what i'm doing wrong PLEASE !
| Thnx
|
| David.
