<code>
<p align="center">Declare Function SetCursorPos Lib "user32.dll" (ByVal x As
Long, ByVal y As Long) As Long</code><br>
SetCursorPos moves the position of the mouse cursor. The coordinates are measured in
pixels. If you try to put the mouse outside of the screen area (for example, 700,40 on a
640x480 display), it will simply go to the edge of the screen. You can safely ignore the
returned value.<br>

SetFileAttributes changes the attributes of a file or directory. The file attributes you
can change are archive, read-only, hidden, and system (other attributes are fixed, such as
compressed). Each of these four attributes can be turned on or off. You can safely ignore
the error code returned.<br>

<h3 ALIGN="center">SetParent Function</h3>
<code>
<p align="center">Declare Function SetParent Lib "user32.dll" (ByVal hWndChild
As Long, ByVal hWndNewParent As Long) As Long</code><br>
SetParent moves a control from one parent object to another. That's right -- the object
itself moves from its original parent to another one. Its relative position is the same
(if it was 40 pixels to the right and 50 down from the upper-left corner in the original
control, it will be 40 pixels right and 50 down from the upper-left corner in the new
control). If successful, the function returns the handle of the parent control from which
the control was moved.<br>
</p>
<table WIDTH="95%" BORDER="2" CELLSPACING="0">

<td WIDTH="20%"><code>hWndChild</code></td>
<td WIDTH="80%">The handle of the control you wish to move. </td>

SetRect sets the four member values of a RECT-type variable. This has the same effect as
manually setting the .Left, .Top, .Right, and .Bottom settings equal to what you want, but
the function takes one line instead of four to do so. You can safely ignore the value
returned.<br>

SetRectEmpty sets a RECT-type variable to an empty state. This function sets all of the
member values of a rectangle to 0. This type of rectangle is considered empty because it
has no width nor height. You can safely ignore the value returned.<br>

SetWindowPos moves a window to a new location in all three dimensions. You can change its
coordinate position as well as its Z-order position (the Z-order says which windows are on
top of others). You can also resize the window. This is similar, but much more powerful,
to setting a window's .Left, .Top, .Right, .Bottom, and other properties manually. You can
safely ignore the value returned.<br>
