Este es mi codigo:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn_eliminar.Click
If MsgBox("¿Está seguro de eliminar al usuario " & Me.txt_nombre.Text & "?", MsgBoxStyle.YesNo, "Administrador") = MsgBoxResult.Yes Then
Try
cn.ConnectionString = var_cn
If cn.State = ConnectionState.Open Then
cn.Close()
End If
cn.Open()
With cmd
.Connection = cn
.CommandType = CommandType.Text
.CommandText = "DELETE FROM USUARIO WHERE (usuario_usuario='" & Me.txt_usuario.Text & "');"
.ExecuteNonQuery()
limpiar_controles()
End With
cn.Close()
Me.Response.Redirect("Default2.aspx")
Catch ex As Exception
Me.Label1.Text = "error" + ex.Message
End Try
Else
Me.Response.Redirect("Default2.aspx")
End If
End Sub
ya esta mi sitio levantado a traves del FTP, cuando doy clic en el boton eliminar se tiene que presentar un mensaje en un msgbox prguntando si estoy segura de eliminar dicho registro; pero en vez de eso se presenta este error:
