vba - Length of a string for a data validation list -


i having trouble data validation list. i'm using vba generate list database(another page of workbook).

the string, contains list, can greater 255 char.

when string greater 255 char, close file, try reopen file, says , suppresses data validation lists in workbook.

is there way work around error?

here code using:

for iter4 = 2 nbwsheet              if wsheet.cells(iter4, 2) = cat , wsheet.cells(iter4, colmod) = "x" , wsheet.cells(iter4, colstd) = "oui"                  tablevalue = wsheet.cells(iter4, 4).value & " - " & wsheet.cells(iter4, 7).value                 tablevalue = replace(tablevalue, ",", chr(130)) 'remplace la virgule par le symbole alt0130                 table = table & "," & tablevalue 'création de la liste              end if          next iter4          'ajout de la list         cells(iglob, 5).validation             .delete             .add type:=xlvalidatelist, alertstyle:=xlvalidalertstop, operator:= _             xlbetween, formula1:=table             .ignoreblank = true             .incelldropdown = true             .inputtitle = ""             .errortitle = ""             .inputmessage = ""             .errormessage = ""             .showinput = ""             .showerror = ""         end 

any appreciated.

note : code generates many data validation lists

i found solution problem.

to make work, generated list in hidden sheet. of lists in column a. know witch list goes where, made iteration calculation each list. when list generated know start , end in column a

here code use

            iter4 = 2 nbwsheet              if wsheet.cells(iter4, 2) = cat , wsheet.cells(iter4, colmod) = "x" , wsheet.cells(iter4, colstd) = "oui"                  tablevalue = wsheet.cells(iter4, 4).value & " - " & wsheet.cells(iter4, 7).value                 tablevalue = replace(tablevalue, ",", chr(130)) 'remplace la virgule par le symbole alt0130                 sheets("hidden").cells(iterrow, 1).value = tablevalue                 iterrow = iterrow + 1                 rowcat = rowcat + 1              end if          next iter4          'calcul du nombre de ligne dans la feuille hidden pour avoir la bonne information dans chaque liste         rowcount = worksheetfunction.counta(sheets("hidden").columns(1))         rowdebut = rowcount - rowcat + 1         'ajout de la liste         cells(iglob, 5).validation             .delete             .add type:=xlvalidatelist, alertstyle:=xlvalidalertstop, operator:= _             xlbetween, formula1:="=hidden!a" & rowdebut & ":a" & rowcount             .ignoreblank = true             .incelldropdown = true             '.inputtitle = ""             '.errortitle = ""             '.inputmessage = ""             '.errormessage = ""             '.showinput = ""             '.showerror = ""         end         iglob = iglob + 1         rowcat = 0     end if
