我在寫一個簡單的應用程序來將記錄添加到由MS Access支持的數據庫。以下是我的代碼示例。我不確定它爲什麼不起作用。有什麼建議麼? Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Dim dsTable As Data
我目前工作的一些代碼,需要日期的比較如下: public int compare(ItemLocation o1, ItemLocation o2) {
try {
SimpleDateFormat sdf = new SimpleDateFormat("MM-dd-yyyy");
Date date1 = sdf.parse(o1.getDatePu
當我運行我的應用程序,我有這個異常 Cannot create instance of 'MainWindow' defined in assembly 'MediaTransferTester, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. Exception has been thrown by the target of an
