Here’s a demo for using a Label control as a splitter between two controls, as well as sample code for employing the splitter in an Explorer-like application:

 Option ExplicitPrivate mbResizing As Boolean	'flag to indicate whether mouse left	'button is pressed downPrivate Sub Form_Load()	TreeView1.Move 0, 0, Me.ScaleWidth / 3, _		Me.ScaleHeight	ListView1.Move (Me.ScaleWidth / 3) + 50, 0, _		(Me.ScaleWidth * 2 / 3) - 50, _		Me.ScaleHeight	Label1.Move Me.ScaleWidth / 3, 0, 100, _		Me.ScaleHeight	Label1.MousePointer = vbSizeWEEnd SubPrivate Sub Label1_MouseDown(Button As Integer, Shift As _	Integer, X As Single, Y As Single)	If Button = vbLeftButton Then mbResizing = _		TrueEnd SubPrivate Sub Label1_MouseMove(Button As _	Integer, Shift As Integer, X As _	Single, Y As Single)	'resizing controls while the left mousebutton is 	'pressed down	If mbResizing Then		Dim nX As Single		nX = Label1.Left + X		If nX < 500 Then Exit Sub		If nX > Me.ScaleWidth - 500 Then Exit Sub		TreeView1.Width = nX		ListView1.Left = nX + 50		ListView1.Width = Me.ScaleWidth - nX - _			50		Label1.Left = nX	End IfEnd SubPrivate Sub Label1_MouseUp(Button As Integer, _	Shift As Integer, X As Single, Y As Single)	mbResizing = FalseEnd Sub
