Question

如果窗口闪烁，我正在尝试监视其他进程。

我尝试在 user32 中使用 GetMessage API，但没有从给定的句柄中获取任何消息。我正在尝试捕获“消息0x0118”，它在启动窗口时出现在spy ++中

[DllImport("user32.dll")]
static extern int GetMessage(out tagMSG lpMsg, IntPtr hWnd, uint wMsgFilterMin, uint wMsgFilterMax);

var p = Process.GetProcessesByName("process").FirstOrDefault();
tagMSG msg = new tagMSG();
DWORD res = 1;
while (res != 0)
{
    res = GetMessage(out msg, p.MainWindowHandle, 0, 0);
    if (res == -1)
    {
        Console.Write("-1");
    }
    else
    {
        if (msg.message == 0x0118)
        {
            Console.WriteLine("flashing");
        }
        else
        {
            Console.WriteLine(msg.message.ToString("x2"));
        }
    }
}
class POINT
{
    public long x;
    public long y;
}
class tagMSG
{
    public HWND hwnd;
    public UINT message;
    public WPARAM wParam;
    public LPARAM lParam;
    public DWORD time;
    public POINT pt;
    public DWORD lPrivate;
}

using HWND = System.IntPtr;
using UINT = System.UInt32;
using WPARAM = System.IntPtr;
using LPARAM = System.IntPtr;
using DWORD = System.Int32;

运行此代码时，它将在 GetMessage 行处停止并等待消息，但消息永不出现。我将 spy ++ 中的Handle与 p.MainWindowHandle 进行了比较。注意：以管理员身份运行Visual Studio

用于另一个进程（如Spy ++）的GetMessage API
