Otherwise, the xPos parameter is not used.yPosSpecifies the vertical position of the cursor, in screen coordinates, if a window menu command is chosen with the mouse. This parameter is -1 if the command is chosen using a system accelerator, or zero if using a mnenomic.

In WM_SYSCOMMAND messages, the four low-order bits of the uCmdType parameter are used internally by Windows.

sankis 呵呵！是我理解错了，sorry
procedure TForm1.FormCreate(Sender: TObject); begin with Application do SetWindowLong(Handle, GWL_EXSTYLE, GetWindowLong(Handle, GWL_EXSTYLE) and not WS_EX_APPWINDOW or WS_EX_TOOLWINDOW); SetWindowPos(Handle, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE or SWP_NOSIZE); end;
fei19790920(饭桶的马甲（抵制日货）) oh ye谢谢你啦！太感谢了！是不是只要给它SWP_NOMOVE or SWP_NOSIZE属性就可以了呢？？？
你理解错误了 with Application do SetWindowLong(Handle, GWL_EXSTYLE, GetWindowLong(Handle, GWL_EXSTYLE) and not WS_EX_APPWINDOW or WS_EX_TOOLWINDOW);//不显示在任务栏上 SetWindowPos(Handle, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE or SWP_NOSIZE); //设置为最顶层窗口
SetWindowPos(Handle, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOSIZE or SWP_NOMOVE)只要加这句话就OK了！

Params.WndParent := FindWindow('Shell_TrayWnd',nil);
实质还是将窗口设置成顶层窗口我测试下来结果一样，“显示桌面”可以忽略，但是其他窗口仍旧无法显示在其前面！
1、最大化
2、没有标题栏
3、忽略“显示桌面”
4、最好在其他所有窗口的底层，不能是顶层窗口
5、不影响任务栏的显示
我总结一下，就好象是一个类似虚拟桌面的窗口。我现在在尝试钩子，现在还在实验（我会把我所遇到的和所学到的都公布出来，可以方便更多的人:p）
可是,据我所知,显示桌面并不会给窗口发什么消息......
好了！谢谢你了！我用SPY++看过了！消息是有的，只有两个……不过现在好了！对了！

你能不能稍微给我讲讲关于Shell_TrayWnd和Progman两个窗口的啊？关于Windows shell我不是很熟悉，我是要去买几本shell的书看看了！
//任务栏
(空) - Shell_TrayWnd (196672)
├开始 - Button (196676)
├(空) - TrayNotifyWnd (262188)
│├16:49 - TrayClockWClass (196680)
│├(空) - SysPager (196682)
││└通知区域 - ToolbarWindow32 (196684)
│└(空) - Button (196686)
└(空) - ReBarWindow32 (65686)
├运行应用程序 - MSTaskSwWClass (65692)
│└运行应用程序 - ToolbarWindow32 (65696)
└Quick Launch - ToolbarWindow32 (65690)//桌面(就是你要显示的东东)
Program Manager - Progman (65702)
└(空) - SHELLDLL_DefView (65704)
└FolderView - SysListView32 (65706)
Delphi一切正常，但是在vc里很奇怪，我就加了一下这句话::SetParent(m_hWnd, ::FindWindow("Progman", NULL));忽略“显示桌面”可以，但是下面任务栏中没有显示，而且窗口总是在最底层！我现在还在研究！（我用的是对话框工程）
这我在OnCreate里加上这句话可以么？为什么delphi可以，vc里却上面的问题呢？你有何意见？
可能与你建立的Window是对话框有关
