popup窗口，点击按钮就是弹不出提醒窗口，哪位知道是什么问题呀？

所有代码我都是照书上源代码复制出来的，原来的程序能运行，按原样新建程序，把代码复制过来就不行，窗体名字都是一样的。

显示出一个标题栏，没在右下方，窗体像是没到右下方，也没显示出来，代码都是从书的源代码拷过来的，不知要设置什么控件的属性，看了timer时间设置是一样的100没错。哪位知道怎么解呀？

[LorenLiu]

貌似你在

public void Show()
{
switch (this.InfoState)
{
case InformStyle.Vanish://窗体隐藏
this.InfoState = InformStyle.Displaying;//设置窗体的操作状态为显示中
this.SetBounds(Rect.X, Rect.Y + Rect.Height, Rect.Width, 0);//显示Popup窗体，并放置到屏幕的底部
ShowWindow(this.Handle, 4);//显示窗体
this.timer1.Interval = 100;//设置时间间隔为100
this.timer1.Start();//启动计时器
break;

这部分里面没有设置InfoStyle。

尝试加入this.InfoState = InformStyle.Displaying;

[LorenLiu]

Sorry,看错了，你上面有这句话。。。

[LorenLiu]

你加个断点进到timer的tick响应事件中，打个断点看看是不是Form的位置不对了。

[wufayou433024]

知道了，timer的单击事件，没关联上。

[兔子-顾问]

下次贴代码用UBB排版一下。
例如

你的代码

按提示，你尝试吧
public void Show()
改为：
public new void Show()

[LorenLiu]

提示不是写的很清楚了吗？你得把

partial class Frm_Popup : System.Windows.Forms.Form
这个类中的
public void Show()

这个方法改一下，因为对于它的基类Form也有一个Show方法，你有几种选择：
1. 把这个方法改成 public new void Show()
2. 修改方法名为ShowForm这种不会和Form中方法重名的
3. 看看你的工程属性里是不是把Build选项卡中的Treat warning as errors设置成了All，如果是的话，把它设置成None就可以看到这个问题作为warning出现，而不会编译错误了

[LorenLiu]

sorry看错了，你这个本来就是warning，那可以忽略我写的第三种解决方法

代码太长了~~帮顶一下

到底哪儿错了.说明就行,这么长谁有时间一行行看哪!@!@

[wufayou433024]

我试了各位的方法还是不行，错误是没有了，点按钮后就是弹不出提醒窗口

Rect计算看不懂，用这个System.Drawing.Rectangle rect = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea;
下面两句位置调换一下
this.SetBounds(Rect.X,Rect.Y,Rect.Width,Rect.Height);
//显示Popup窗体，并放置到屏幕的底部
ShowWindow(this.Handle,4);
