下面的代码只是一个插入代码,它调用我在sql中创建的存储过程 InsertDataIntoTable 。代码有效,但我想添加的是一个消息框(或标签),以确保已成功插入数据。

Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles save_btn.Click
    Try

        sqlCon = New SqlConnection(strConn)

        Using (sqlCon)

            Dim sqlComm As New SqlCommand()

            sqlComm.Connection = sqlCon

            sqlComm.CommandText = "InsertDataIntoTable"
            sqlComm.CommandType = CommandType.StoredProcedure

            sqlComm.Parameters.AddWithValue("Years", ddl_year.SelectedItem.Text)
            sqlComm.Parameters.AddWithValue("StateForest", SFtx.Text)
            sqlComm.Parameters.AddWithValue("PrivateForest", PFtx.Text)
            sqlComm.Parameters.AddWithValue("TotalForest", totalForesttx.Text)
            sqlComm.Parameters.AddWithValue("PercentageSF", PercentageSFtx.Text)
            sqlComm.Parameters.AddWithValue("PercentageTotal", PercentageTotal.Text)

            sqlCon.Open()

            sqlComm.ExecuteNonQuery()

        End Using
        LoadData()

    Catch ex As Exception

    End Try

您可以使用sqlComm.ExecuteNonQuery()

Dim RowsAffected as Integer = sqlComm.ExecuteNonQuery()

.ExecuteNonQuery返回受影响的行数,以便您可以比较该值以确保数据已成功插入。

类似的东西:

If RowsAffected > 0 Then
     Msgbox("Record has been successfully inserted")
End If
