问题描述

我有一个在WinForms中实现的对话框，在屏幕右下方显示为通知对话框。问题是，每当显示它需要重点，只有当TopMost = true时才会发生这种情况。如何解决这个问题？

解决方案

您需要从Form继承并覆盖几个属性：

  [Flags] 
枚举WS_EX 
 {
 TOPMOST = 0x00000008，
} 
 
 class TopMostForm：Form 
 {
 protected override CreateParams CreateParams 
 {
 get 
 {
 var baseParams = base.CreateParams; 
 baseParams.ExStyle | =（int）WS_EX.TOPMOST; 
 return baseParams; 
} 
} 
 
 protected override bool ShowWithoutActivation 
 {
 get {return true; } 
} 
}

然后只需在这个表单上显示Show（）它将显示为最高和无效。

I have a dialog implemented in WinForms that is shown as a notify dialog on the bottom right of the screen. The problem is that whenever is shown it takes the focus and this happens only when TopMost = true. How can I solve this?

解决方案

You need to inherit from Form and override a couple of properties:

[Flags]
enum WS_EX
{
    TOPMOST = 0x00000008,
}

class TopMostForm : Form
{
    protected override CreateParams CreateParams
    {
        get
        {
            var baseParams = base.CreateParams;
            baseParams.ExStyle |= (int)WS_EX.TOPMOST;
            return baseParams;
        }
    }

    protected override bool ShowWithoutActivation
    {
        get { return true; }
    }
}

Then just simply Show() on this form and it will be displayed as topmost and inactive.
