' Name: Add Splitter Bars to your app *R
' evised*
' Description:Add vertical and horizonta
' l splitter bars to your application. Thi
' s
code creates a form with three panes, and two splitter bars. I originally
found the code in Planet Source Code last year, but found a couple of
bugs, so I rebuilt it from scratch, and added the horizontal splitter.
There are no DLL's or references to worry about, very easy to use.
' By: Eugene
'
'
' Inputs:It is easy to integrate into yo
' ur applications. You simply paste whatev
' er
objects that you want to use into one of the three picture boxes used as
frames. Then in the _Resize event of each, change the .Move statement to
your object (or control).
'
' Returns:None
'
'Assumes:Copy the code and paste it into
' a text editor (like notepad). Save the f
' ile
as Form1.frm. You can always change it later.
'
'Side Effects:None
'This code is copyrighted and has limite
' d warranties.
