很多时候。我们的窗体设计需要一个引导窗体。当打开一个项目的窗体时,默认的是先打开一个欢迎或介绍项目信息的引导窗体,几秒钟后再打开项目的主窗体。这几秒时间最重要的意义是等待主窗体加载程序完毕。
实现带引导窗体的窗体设计操作流程:在项目里先设计两个窗体,并把Form1改名为Frm_Main,把Form2改名为Frm_Start。切记在更改窗体名称的时候按下ENTER确认此更改影响到了整个工程。
接着,把项目所需要的图片资源设计到图片资源管理器,并把图片设计为相应窗体的背景,stretch。这一步的操作,详见本文作者写的其他文章。
进一步地,在Frm_Main窗体创建Load事件,在事件里定义Frm_Start的对象,并打开Frm_Start窗体。
进一步地,在Frm_Start窗体创建Load事件、设计Timer组件,并设计一个Tick事件,再创建一个FormClosed事件;在其Load事件中启动定时器,设置定时器动作时间为10s,在定时器的Tick事件中设计为关闭窗体引导窗体;在其FormClosed事件设计为关闭定时器;
好了,至此符合项目需要的操作流程设计完毕,下面上代码。
