Innanzitutto salve!!!
Quando eseguo il programma, mi appare l' errore scritto sopra. Nel log esce scritto anche"A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll".
Il codice è questo:
codice:
Public Class Form1
Dim wurtot As Decimal
Private Sub WPmeno_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles WPmeno.Click
wurtot = wurtot - 1
WPrisult.Text = wurtot
End Sub
Private Sub WPiu_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles WPiu.Click
wurtot = wurtot + 1
WPrisult.Text = wurtot
End Sub
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
tot.Text = ("Salve, vorrei ") + wurtot + ("Wurstel e patatine")
End Sub
End Class
Inoltre il compilatore localizza l' errore qui:
codice:
"tot.Text = ("Salve, vorrei ") + wurtot + ("Wurstel e patatine")"
Come posso correggere il problema?.
