如何以编程方式更改Windows 7 Aero/Window边框颜色？

Question

我正在考虑制作一个程序,根据电池电量改变Windows 7的航空颜色.我是c#的新手,我想知道如何以编程方式更改Windows 7 Aero

我有这个代码

[DllImport("dwmapi.dll", EntryPoint = "#127", PreserveSig = false)]
    public static extern void DwmGetColorizationParameters(out WDM_COLORIZATION_PARAMS                   parameters);

[DllImport("dwmapi.dll", EntryPoint = "#131", PreserveSig = false)]
public static extern void DwmSetColorizationParameters(WDM_COLORIZATION_PARAMS parameters, uint uUnknown);

public struct WDM_COLORIZATION_PARAMS {
    public uint Color1;
    public uint Color2;
    public uint Intensity;
    public uint Unknown1;
    public uint Unknown2;
    public uint Unknown3;
    public uint Opaque;
}

虽然,我不知道如何使用它并设置自定义颜色.

没有记录的API.这完全是设计上的:此设置旨在由用户更改,而不是由应用程序更改.并且有一个内置的小程序供用户使用:Personalize控制面板.

但是就像你已经提到过的代码一样,你可以使用一个未记录的 API DwmSetColorizationParameters.您只需要仔细测试您的代码是否适用于所有目标操作系统,并注意它可能会破坏任何新版本的Windows和/或当前版本的Windows的任何更新.

我知道它曾经在Windows 7中运行,但我没有使用所有最新的服务包和其他更新进行测试,也不知道它是否适用于Windows 8.这完全由你来测试.使用未记录的API是很多工作.

不过你很幸运.其他人已经为您完成了逆向工程.(可能还有其他人,就像编写你在问题中显示的代码的人一样.给他们一点信誉会很好.也许是这个人？)

以下是您使用它的方式:

using System;
using System.Drawing;
using System.Globalization;
using System.Runtime.InteropServices;

class DwmManager
{
   private struct DWM_COLORIZATION_PARAMS
   {
      public uint clrColor;
      public uint clrAfterGlow;
      public uint nIntensity;
      public uint clrAfterGlowBalance;
      public uint clrBlurBalance;
      public uint clrGlassReflectionIntensity;
      public bool fOpaque;
   }

   [DllImport("dwmapi.dll", EntryPoint = "#127", PreserveSig = false)]
   private static extern void DwmGetColorizationParameters(out DWM_COLORIZATION_PARAMS parameters);

   [DllImport("dwmapi.dll", EntryPoint = "#131", PreserveSig = false)]
   private static extern void DwmSetColorizationParameters(ref DWM_COLORIZATION_PARAMS parameters,
                                                           bool unknown);

   // Helper method to convert from a Win32 BGRA-format color to a .NET color.
   private static Color BgraToColor(uint color)
   {
      return Color.FromArgb(Int32.Parse(color.ToString("X"), NumberStyles.HexNumber));
   }

   // Helper method to convert from a .NET color to a Win32 BGRA-format color.
   private static uint ColorToBgra(Color color)
   {
      return (uint)(color.B | (color.G << 8) | (color.R << 16) | (color.A << 24));
   }

   // Gets or sets the current color used for DWM glass, based on the user's color scheme.
   public static Color ColorizationColor
   {
      get
      {
         // Call the DwmGetColorizationParameters function to fill in our structure.
         DWM_COLORIZATION_PARAMS parameters;
         DwmGetColorizationParameters(out parameters);

         // Convert the colorization color to a .NET color and return it.
         return BgraToColor(parameters.clrColor);
      }
      set
      {
         // Retrieve the current colorization parameters, just like we did above.
         DWM_COLORIZATION_PARAMS parameters;
         DwmGetColorizationParameters(out parameters);

         // Then modify the colorization color.
         // Note that the other parameters are left untouched, so they will stay the same.
         // You can also modify these; that is left as an exercise.
         parameters.clrColor = ColorToBgra(value);

         // Call the DwmSetColorizationParameters to make the change take effect.
         DwmSetColorizationParameters(ref parameters, false);
      }
   }
}

将该类添加到项目后,即可通过该ColorizationColor属性与其进行交互.像评论说,该DWM_COLORIZATION_PARAMS结构为您提供了大量的信息.如果您愿意,可以添加属性以获取/设置每个附加参数.虽然需要一些实验来弄清楚他们究竟做了什么.

请注意,在运行任何这些功能之前,还需要检查主机操作系统是否支持和启用DWM组合.(否则,该PreserveSig属性将确保抛出异常.)这是相当明显的,但无论如何值得一提.为此,您还需要此功能:

[DllImport("dwmapi.dll")]
private static extern int DwmIsCompositionEnabled(ref bool pfEnabled);
