What I need is: what trigger to use and where to put it.
我将给你一个例子,说明我正在做些什么。
除合同财务领域外,我有一份完全可以编辑的合同表格。 我希望用户发布一个叫做“兑换率”的纽芬兰语,这将产生一个“债务-债务”的触发器,并打电话到“情况”(最新)。
现在,在这个屏幕上,我有用户更改合同从50k升至100k等财务信息。 然后,用户储蓄和退出。 然后将结束儿童表格“最新信息”并显示母体形式“合同”。 问题在于,它仍然掌握着这方面的所有老信息。 当信息从儿童形式“传票”功能中恢复时,我需要这种信息。
在<代码>WHEN-BUTTON-PRESSED的触发器中,在你发布<代码>CALL_FORM之前,将一个变数(例如一个隐藏的项目或一个全球性的变数)设定为一定价值,例如 CALLED_THE_FORM 。
在<代码>上 WHEN-WINDOW-ACTIVATED, 检测变量,条件是: CALLED_THE_FORM , 重塑变量(例如NUL), 并操作在用户从形式返回时所希望操作的任何代码(例如执行查询或执行)。
或者说,只是从<代码>上执行问题。 WHEN-WINDOW-ACTIVATEDstart——如果您希望每当用户返回表格时都会复读。 但是,我个人只想在我相信绝对需要时重新学习。
