我有一个应用程序，其中表单类DataEntryForm.Show.Dialog（）;在每小时的57分钟每小时执行一次。我展示的表单的构造函数有一些代码来初始化一些变量，这些变量用于设置表单中组合框的索引。启动应用程序后，显示的第一个表单是完美的。用户填充并单击按钮以记录数据并关闭表单。表格下一个小时再次显示，但变量没有更新，我希望它们增加一个小时。我已经尝试了很多东西：处理，移动变量以将构造函数初始化为另一个方法，并从Form_Shown事件处理程序调用该方法。我想我错过了一些简单的东西...我是新手。看起来即使表单关闭，下一个show.dialog也是原始表单的相同实例。

您正在创建一个新的对话框表单实例，因此它无法使用已处理的表单。
DataEntryForm DataEntryForm = new DataEntryForm（）;
<强> DataEntryForm.ShowDialog（）;
你能详细说明以下句子吗？
＆＃34;但变量没有更新，我期待它们 增加一小时＆＃34;
也许问题是逻辑而不是窗口。我强烈建议将逻辑分离到专用方法，并测试它，无论表单如何。通过这样做，您可以隔离问题。 我希望它能带领你。

Problem solved. clockHr was declared and a value was defined at the class level. The value should have been defined in the constructor. Working perfect now.
