获取托盘图标信息时出错

Question

[DllImport("User32.dll", EntryPoint = "SendMessage")]
private static extern int SendMessage(IntPtr hWnd,uint Msg,int wParam,int lParam);
[DllImport("User32.dll", EntryPoint = "SendMessage")]
private static extern int SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, StringBuilder lParam);static void Main(string[] args)
{
 
            IntPtr FWIN1, CWIN1, CWIN2, CWIN3, CWIN4, CWIN5, CWIN6; //窗体句柄
            FWIN1 = FindWindow("Shell_TrayWnd", null); //任务栏
            CWIN1 = FindWindowEx(FWIN1, 0, "TrayNotifyWnd", null);//托盘
            CWIN4 = FindWindowEx(CWIN1, 0, "SysPager", null);
            CWIN6 = FindWindowEx(CWIN4, 0, "ToolbarWindow32", null);      int count = SendMessage(CWIN6, TB_BUTTONCOUNT, 0, 0);
      Console.WriteLine("一共有{0}个图标", count);
      StringBuilder buffer = new StringBuilder(1024);
      for (int i = 1; i < count; i++)
      {
         SendMessage(CWIN6, TB_GETBUTTONTEXTW, (IntPtr)i, buffer);
         Console.WriteLine(buffer.ToString());
      }}为什么我在发送TB_GETBUTTONTEXTW消息的时候explorer就报错。我是想列出目前托盘中的图标信息，在选择其中的一个，进行操作。我要怎么能获得其中一个图标？

Answer 1

C# 中的NotifyIcon 控件,你应该去看看.

Answer 2

我不是控制自己程序的NotifyIcon，而是其他程序的，比如QQ,迅雷等

Answer 3

在网上看了下，好多是delphi写的，我改成C#的，现在就不报错了，但是输出结果为空
  int count = SendMessage(CWIN6, TB_BUTTONCOUNT, 0, 0);
 Console.WriteLine("一共有{0}个图标", count);
                        
 uint procID;
 GetWindowThreadProcessId(CWIN6, out procID);
 Console.WriteLine("进程号{0}", procID); int hProcess = OpenProcess(PROCESS_VM_OPERATION | PROCESS_VM_READ | PROCESS_VM_WRITE, false, procID);
 Console.WriteLine("进程号{0}", hProcess); uint pointer  =  VirtualAllocEx(hProcess, 0, 4096, 0x1000 | 0x2000, 0x04);
 Console.WriteLine("地址{0}", pointer.ToString());
 if (pointer != 0)
 {   
    StringBuilder buffer = new StringBuilder(1024);
    TB_BUTTON bt;
    for (int i = 0; i < count; i++)
    {
       SendMessage(CWIN6, TB_GETBUTTON, i, (int)pointer);
       ReadProcessMemory(hProcess, pointer, out bt, 1024, 0);                        
       SendMessage(CWIN6, TB_GETBUTTONTEXTW, bt.idCommand, (int)pointer);
       ReadProcessMemory(hProcess, pointer+1024, buffer, 1024, 0);
       Console.WriteLine("输出");
       Console.WriteLine(buffer.ToString());
     }
}但输出的buffer为空，也不知道改的对不对。搞不定了

Answer 4

        struct TB_BUTTON
        {
            public int iBitmap;
            public int idCommand;
            public byte fsState;
            public byte fsStyle;
            public uint dwData;
            public int iString; 
        }
