  • WebKit.NET-0.5简单应用(2)——音量解决方案

    查找WebKit.NET相关文档,没有找到音量控制解决方法。换思路进行解决,尝试用Win32 API进行解决

    [DllImport("winmm.dll")]
    public static extern int waveOutSetVolume(IntPtr h, uint dwVolume);
    

    试了试是可以调整音量的,全部代码如下

    using System;
    using System.Collections.Generic;
    using System.Text;
    using System.Runtime.InteropServices;
    
    namespace VolumeControl
    {
        public static class VolumeControl
        {
            public enum INTERNETFEATURELIST
