设置不同的任务栏图标的标题栏（C＃）显示的图标？ [英] Setting a different taskbar icon to the icon displayed in the titlebar (C#)?

问题描述

我有我的应用程序图标的两个深色和浅色版本;黑暗版本的作品最好的灰色表面，如Windows XP任务栏，那里的轻型版本最适合作为标题栏中显示的图标。

有没有一种方法，我可以设置在任务栏比在C＃在我的表单中使用的（P / Invoke的是罚款）？

解决方案

不同的图标图标发送WM_SETICON消息以不同的图标表单处理的ICON_SMALL和ICON_BIG参数：

<预类=郎-CS prettyprint-覆盖> 函数[DllImport（user32.dll中，字符集= CharSet.Auto）]
静态外部的IntPtr SendMessage函数（IntPtr的的HWND，UINT消息，诠释的wParam，lParam的的IntPtr）;

私人常量UINT WM_SETICON = 0x80u;
私人const int的ICON_SMALL = 0;
私人const int的ICON_BIG = 1;

公共MyForm的（）
{
的InitializeComponent（）;

SendMessage函数（this.Handle，WM_SETICON，ICON_SMALL，Properties.Resources.IconSmall.Handle）;
SendMessage函数（this.Handle，WM_SETICON，ICON_BIG，Properties.Resources.IconBig.Handle）;
}


I have both dark and light versions of my application icon; the dark version works best on gray surfaces such as Windows XP taskbar, where the light version works best as an icon in the titlebar.

Is there a way I can set the icon in the taskbar to a different icon than the one used in my form in C# (P/Invoke is fine)?

解决方案

Send the WM_SETICON message to your form with different icon handles for the ICON_SMALL and the ICON_BIG parameter:

[DllImport("user32.dll", CharSet = CharSet.Auto)]
static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, int wParam, IntPtr lParam);

private const uint WM_SETICON = 0x80u;
private const int ICON_SMALL = 0;
private const int ICON_BIG = 1;

public MyForm()
{
    InitializeComponent();

    SendMessage(this.Handle, WM_SETICON, ICON_SMALL, Properties.Resources.IconSmall.Handle);
    SendMessage(this.Handle, WM_SETICON, ICON_BIG, Properties.Resources.IconBig.Handle);
}
