我可以以某种方式设置“SHELLDLL_DefView”的父级。处理“WorkerW” [英] Can I somehow set the Parent of "SHELLDLL_DefView" handle to a "WorkerW"

问题描述

您好，



在Windows启动时（使用Windows 10），窗口顺序（通过Spy ++）如下所示：

< pre lang =text> WorkerW
Progman
* SHELLDLL_DefView

按下WIN + TAB后，它看起来像这样：

 Progman 
 WorkerW 
 * SHELLDLL_DefView 

因为我的程序是SHELLDLL_DefView的子项，所以它得到了半按WIN + TAB后透明我希望每个代码完成此更改，而不是用户突然完成。



我试过这个，但没有任何反应：

  IntPtr  progmanHandle = FindWindowEx（ IntPtr  .Zero，< span class =code-sdkkeyword> IntPtr  .Zero，  Progman，< span class =code-keyword> null ）; 
  IntPtr  shell = FindWindowEx（progmanHandle， IntPtr  .Zero，  SHELLDLL_DefView， null ）; 
  IntPtr  workerWHandle = FindWindowEx（ IntPtr  .Zero， IntPtr  .Zero，  WorkerW，空）; 
 SetParent（shell，workerWHandle）; 

请帮助！

解决方案

  private   static   IntPtr  GetDesktopListView（）{
  var  hDesktop =  IntPtr的 .Zero; 
  var  hProgman = W32Api.FindWindow（  Progman， ）; 
 
  if （hProgman！=  IntPtr  .Zero）{
  //   hProgman可用！ 
 hDesktop = W32Api.FindWindowEx（hProgman， IntPtr  .Zero，  SHELLDLL_DefView，
  IntPtr  .Zero）; 
} 
 如果（hDesktop！=  IntPtr  .Zero）{
  //   hDesktop可用！ 
 返回 W32Api.FindWindowEx（hDesktop， IntPtr  .Zero，  SysListView32，
  IntPtr  .Zero）; 
} 
 
  //  如果我们达到这一点，那意味着SHELLDLL_DefView 不是兄弟姐妹 
  //  Progman！现在我们要从Progman（Windows 7及更高版本）中生成WorkerW 
  //  （shhhh ...此Windows消息未记录！） 
  const   int  WmSpawnWorker = 0x052C; 
 W32Api.SendMessage（hProgman，WmSpawnWorker， 0 ， 0 ）; 
 
 hDesktop = W32Api.GetDesktopWindow（）; 
  IntPtr  hShellViewWin; 
  var  hWorkerW =  IntPtr  .Zero; 
 执行 {
 hWorkerW = W32Api.FindWindowEx（hDesktop，hWorkerW， < span class =code-string> WorkerW， IntPtr  .Zero）; 
 hShellViewWin = W32Api.FindWindowEx（hWorkerW， IntPtr  .Zero，  SHELLDLL_DefView，
  IntPtr  .Zero）; 
}  while （hShellViewWin ==  IntPtr  .Zero&& hWorkerW！=  IntPtr的 .Zero）; 
  return  W32Api.FindWindowEx（hShellViewWin， IntPtr  .Zero，  SysListView32，
  IntPtr  .Zero）; 
} 

Hi there,

On Windows startup (using Windows 10) the window order (by Spy++) looks like this:

WorkerW
Progman
   * SHELLDLL_DefView

After pressing WIN+TAB it looks like this:

Progman
WorkerW
   * SHELLDLL_DefView

Since my program is a child of SHELLDLL_DefView and it gets semi-transparent after pressing WIN+TAB i want to get this change done per code and not suddenly by a user.

I tried this, but nothing happens:

IntPtr progmanHandle = FindWindowEx(IntPtr.Zero, IntPtr.Zero, "Progman", null);
IntPtr shell = FindWindowEx(progmanHandle, IntPtr.Zero, "SHELLDLL_DefView", null);
IntPtr workerWHandle = FindWindowEx(IntPtr.Zero, IntPtr.Zero, "WorkerW", null);
SetParent(shell, workerWHandle);

Please help!
Julian

private static IntPtr GetDesktopListView(){
    var hDesktop = IntPtr.Zero;
    var hProgman = W32Api.FindWindow("Progman", "");

    if (hProgman != IntPtr.Zero){
        // hProgman is usable!
        hDesktop = W32Api.FindWindowEx(hProgman, IntPtr.Zero, "SHELLDLL_DefView", 
            IntPtr.Zero);
    }
    if (hDesktop != IntPtr.Zero){
        // hDesktop is usable!
        return W32Api.FindWindowEx(hDesktop, IntPtr.Zero, "SysListView32", 
            IntPtr.Zero);
    }

    // If we reach this point, that means that "SHELLDLL_DefView" is NOT a sibling
    // of "Progman"! Now we gotta spawn "WorkerW" from "Progman" (Windows 7 and beyond)
    // (shhhh... this windows message is NOT DOCUMENTED!)
    const int WmSpawnWorker = 0x052C;
    W32Api.SendMessage(hProgman, WmSpawnWorker, 0, 0);

    hDesktop = W32Api.GetDesktopWindow();
    IntPtr hShellViewWin;
    var hWorkerW = IntPtr.Zero;
    do {
        hWorkerW = W32Api.FindWindowEx(hDesktop, hWorkerW, "WorkerW", IntPtr.Zero);
        hShellViewWin = W32Api.FindWindowEx(hWorkerW, IntPtr.Zero, "SHELLDLL_DefView", 
            IntPtr.Zero);
    } while (hShellViewWin == IntPtr.Zero && hWorkerW != IntPtr.Zero);
    return W32Api.FindWindowEx(hShellViewWin, IntPtr.Zero, "SysListView32",
        IntPtr.Zero);
}
