Forms Shapes

[Bobbo70]

Hi everybody;
How can I change the forms shape to regullar shapes like circles or ellipse or into irregular shapes like rounded corners and undefined edges.:confused:

The following code will show you how to create various kind of window shape :)


Option Explicit
'// WIN32API Function
Private Declare Function CreateRoundRectRgn Lib "gdi32" (ByVal X1 As Long, ByVal Y1 As Long, ByVal X2 As Long, ByVal Y2 As Long, ByVal X3 As Long, ByVal Y3 As Long) As Long
Private Declare Function CreatePolygonRgn Lib "gdi32" (lpPoint As POINTAPI, ByVal nCount As Long, ByVal nPolyFillMode As Long) As Long
Private Declare Function CreateEllipticRgn Lib "gdi32" (ByVal X1 As Long, ByVal Y1 As Long, ByVal X2 As Long, ByVal Y2 As Long) As Long
Private Declare Function SetWindowRgn Lib "user32" (ByVal hWnd As Long, ByVal hRgn As Long, ByVal bRedraw As Boolean) As Long

'// WIN32API Structure
Private Type POINTAPI
x As Long
y As Long
End Type

'// WIN32API Constant
Private Const WINDING = 2

Private Sub Form_Load()
Load frmSample
frmSample.Show
End Sub

Private Sub Form_Unload(Cancel As Integer)
Unload frmSample
End Sub

Private Sub CmdAction_Click(Index As Integer)
Dim hRgn As Long
Dim pt(4) As POINTAPI

Select Case Index
Case 0 '// Ellipse
hRgn = CreateEllipticRgn(0, 0, 200, 400)
Case 1 '// Triangle
pt(0).x = 200
pt(0).y = 0
pt(1).x = 400
pt(1).y = 500
pt(2).x = 0
pt(2).y = 500
pt(3).x = 200
pt(3).y = 0
hRgn = CreatePolygonRgn(pt(0), 4, WINDING)
Case 2 '// Round Rect
hRgn = CreateRoundRectRgn(0, 0, 400, 400, 50, 50)
Case 3 '// Circle
hRgn = CreateEllipticRgn(0, 0, 300, 300)
End Select

SetWindowRgn frmSample.hWnd, hRgn, True
End Sub
