> I want to fill inside Arrow

Use the Polygon() API call rather than drawing lines and filling the inside, this is also a lot quicker so you'll notice a
considerable performance increase if drawing many shapes.

'***
Private Declare Function Polygon Lib "GDI32.dll" ( _
    ByVal hDC As Long, ByRef lpPoint As PointAPI, _
    ByVal nCount As Long) As Long

Private Type PointAPI
    X As Long
    Y As Long
End Type

Private Sub Command1_Click()
    Dim ArrowPts(3) As PointAPI

    ArrowPts(0).X = 20
    ArrowPts(0).Y = 20
    ArrowPts(1).X = 280
    ArrowPts(1).Y = 30
    ArrowPts(2).X = 90
    ArrowPts(2).Y = 90
    ArrowPts(3).X = 100
    ArrowPts(3).Y = 50

    Picture1.FillStyle = 2
    Picture1.FillColor = vbRed
    Picture1.ForeColor = vbGreen

    Call Polygon(Picture1.hDC, ArrowPts(0), 4)
End Sub

> But how to do it and is that possible to change scale of hatch.

You can't change the scales of the default hatch styles, however you can create your own hatch pattern brush and fill your shape
with that.
Here's an old post with an example of creating your own hatch pattern brush:

Hope this helps,
