Hi all, I have a problem. I have a program that needs to read values from an Excel spreadsheet, I have no problems except for blank cells, in fact, not knowing how many rows there are, I thought of a loop to find the first empty row but I vb generates an error under I'll post the offending code, surely will be a bullshit that escapes me.
Thank you all for the help.

Salve a tutti, avrei un problemino. ho un programma che deve leggere dei valori da un foglio di Excel, non ho problemi tranne per le celle vuote, infatti non sapendo quante righe ci sono, ho pensato ad un ciclo per individuare la prima riga vuota ma vb mi genera un errore, sotto vi posto il codice incriminato, sicuramente sarà una cavolata che mi sfugge.
Grazie a tutti per l'aiuto.

VB

While FoglioExcel.Cells(I, 1).value.tostring <> ""
    NumRigheFoglio = NumRigheFoglio + 1
    I = I + 1
End While

grazie

You should probably use (is just a guess, since you did not report the exact error message):

VB

While Not FoglioExcel.Cells(I, 1).Value Is Nothing
