Quelqu'un sait-il comment on peut limiter l'entrée de données à un certain nombre de caractéres ?
Exemple je ne veux que rentrer des nombres sur 4 positions ex..1234
GadgetString
comme ça par exemple 
; Codé par Dobro
; en purebasic 4.00
;- Window Constants
;
Enumeration
#Window_0
EndEnumeration
;- Gadget Constants
;
Enumeration
#String_0
#Text_0
EndEnumeration
Procedure Open_Window_0()
If OpenWindow ( #Window_0 , 216, 0, 600, 300, "New window ( 0 )" , #PB_Window_SystemMenu | #PB_Window_SizeGadget | #PB_Window_TitleBar )
If CreateGadgetList ( WindowID ( #Window_0 ))
StringGadget ( #String_0 , 50, 30, 150, 20, "" , #PB_String_Numeric )
TextGadget ( #Text_0 , 50, 60, 140, 20, "Limité a 6 caracteres" )
EndIf
EndIf
EndProcedure
Open_Window_0()
Repeat ; Start of the event loop

;You can place code here, and use the result as parameters for the procedures

text$= Left (text$,6)
