<code>
<p align="center">Declare Function LineTo Lib "gdi32.dll" (ByVal hdc As Long,
ByVal x As Long, ByVal y As Long) As Long</code><br>
LineTo draws a line from the current point to the point specified on a graphical object.
The line is drawn in the object's <code>.ForeColor</code> property. After the line is
drawn, the endpoint specified is the new current point. This command is similar to Visual
Basic's intrinsic Line method. Keep in mind that, because of the technique used by Windows
to draw lines, the pixel that is the specified endpoint itself is not colored and is not
considered part of the line. Don't ask me why this is done, but it also happens with VB's
Line method. You can safely ignore the value returned.<br>
