1. Como puedo hacer para que un dialogo o ventana este siempre al frente y no se pueda mover ni cambiar de tamaño.

Revisa el ejemplo TestTop.prg

de todas formas te dejo una explicacion de esta funcion que la puedes conseguir en los help de FWH

Changes the size, position, and Z order of a child, pop-up, or top-level window.
Syntax:
SetWindowPos( <hWnd>, <hWndInsertAfter>, <nRow>, <nCol>,

<nWidth>, <nHeight>, <nFlags> ) --> lSuccess

Parameters:
<hWnd> The handle of the window.
<hWndInsertAfter> Handle to the window to precede the positioned window in the Z order. This parameter must be a window handle or one of the following values:

HWND_BOTTOM Places the window at the bottom of the Z order. If the hWnd parameter identifies a topmost window, the window loses its topmost status and is placed at the bottom of all other windows.
HWND_NOTOPMOST Places the window above all non-topmost windows (that is, behind all topmost windows). This flag has no effect if the window is already a non-topmost window.
HWND_TOP Places the window at the top of the Z order.
HWND_TOPMOST Places the window above all non-topmost windows. The window maintains its topmost position even when it is deactivated.
<nRow> Specifies the new position of the left side of the window.
<nCol> Specifies the new position of the top of the window.
<nWidth> Specifies the new width of the window.
<nHeight> Specifies the new height of the window.
<nFlags> Specifies the window sizing and positioning flags. This parameter can be a combination of the following values:

SWP_ASYNCWINDOWPOS If the calling thread and the thread that owns the window are attached to different input queues, the system posts the request to the thread that owns the window. This prevents the calling thread from blocking its execution while other threads process the request.
SWP_DEFERERASE Prevents generation of the WM_SYNCPAINT message.
SWP_DRAWFRAME Draws a frame (defined in the window's class description) around the window.
SWP_FRAMECHANGED Applies new frame styles set using the SetWindowLong function. Sends a WM_NCCALCSIZE message to the window, even if the window's size is not being changed. If this flag is not specified, WM_NCCALCSIZE is sent only when the window's size is being changed.
SWP_HIDEWINDOW Hides the window.
SWP_NOACTIVATE Does not activate the window. If this flag is not set, the window is activated and moved to the top of either the topmost or non-topmost group (depending on the setting of the hWndInsertAfter parameter).
SWP_NOCOPYBITS Discards the entire contents of the client area. If this flag is not specified, the valid contents of the client area are saved and copied back into the client area after the window is sized or repositioned.
SWP_NOMOVE Retains the current position (ignores the X and Y parameters).
SWP_NOOWNERZORDER Does not change the owner window's position in the Z order.
SWP_NOREDRAW Does not redraw changes. If this flag is set, no repainting of any kind occurs. This applies to the client area, the nonclient area (including the title bar and scroll bars), and any part of the parent window uncovered as a result of the window being moved. When this flag is set, the application must explicitly invalidate or redraw any parts of the window and parent window that need redrawing.
SWP_NOREPOSITION Same as the SWP_NOOWNERZORDER flag.
SWP_NOSENDCHANGING Prevents the window from receiving the WM_WINDOWPOSCHANGING message.
SWP_NOSIZE Retains the current size (ignores the cx and cy parameters).
SWP_NOZORDER Retains the current Z order (ignores the hWndInsertAfter parameter).
SWP_SHOWWINDOW Displays the window.

Returns:

<lSuccess> .t. if the function was successful, otherwise .f.

2. ocultar y des-cocultar la barra de inicio de windows.

ShowWindow (FindWindow ('Shell_TrayWnd', Nil) , 0 )
para volver a mostrar cambia el valor de 0 a 1

Daniel,

En windows 7, el botón de inicio del Windows 7 no está invisibilizando. ¿Qué debo hacer?

ShowWindow(FindWindow( 'Shell_TrayWnd',nil), SW_HIDE )

Gracias, saludos.

Porfa, como hago esto en FWH?

For Windows 7 you want to use something like this:

hStart = ::FindWindowEx(GetDesktopWindow(), NULL, "Button", NULL)

Although I think it would be better search for it by name to be sure that you get the right button.

hStart = ::FindWindowEx(GetDesktopWindow(), NULL, "Button", "Start")

Gracias,

Regards, saludos.
