    Dim TransparentColor As Long
    Dim InFirstRegion As Boolean
    Dim InLine As Boolean
    Dim hdc As Long
    Dim PicWidth As Long

    InFirstRegion = True: InLine = False
    x = y = StartLineX = 0
    TransparentColor = 14215660
    For y = 0 To PicHeight - 1
        For x = 0 To PicWidth - 1
            If GetPixel(hdc, x, y) = TransparentColor Or x = PicWidth Then
                If InLine Then
                    InLine = False
                    LineRegion = CreateRectRgn(StartLineX, y, x, y + 1)
                    If InFirstRegion Then
                        FullRegion = LineRegion
                        InFirstRegion = False
                    Else

                    InLine = True
                    StartLineX = x
                End If
            End If
        Next
    Next
    MakeRegion = FullRegion

I want to delete a region

How can I delete a region???

Do you mean the regions that are used in the Windows GDI (Graphical Device Interface)??

without testing I'm pretty sure a simple...

SetWindowRgn picmainskin.hwnd, 0, True

will do.

[icanflyiwillfly]

You may use the CombineRgn function with with the appropriate combine mode like RGN_DIFF to delete a part of a region, or delete an entire region altogether.

thanks,
SetWindowRgn picmainskin.hwnd, 0, True

This code by La Volpe has a few region functions including one for creating a region by mask colour. It's good code.
