Function

How to pass objects like shape as a parameters to a function in VB6 plz explain with example.

Try something like this:

Code:

---

Option Explicit

Private Enum ShapeStyles
    Rectangle = VBRUN.ShapeConstants.vbShapeRectangle
    Square = VBRUN.ShapeConstants.vbShapeSquare
    Oval = VBRUN.ShapeConstants.vbShapeOval
    [Circle] = VBRUN.ShapeConstants.vbShapeCircle
    [Rounded Rectangle] = VBRUN.ShapeConstants.vbShapeRoundedRectangle
    [Rounded Square] = VBRUN.ShapeConstants.vbShapeRoundedSquare
End Enum

Private Sub Form_Load()
    Shape1.Shape = ShapeStyles.[Rounded Rectangle]
End Sub

Private Sub Command1_Click()
    ChangeShape Shape1, ShapeStyles.Oval
End Sub

Private Sub ChangeShape(shp As Shape, newShape As Integer)
    Shape1.Shape = newShape
End Sub

Why would you define an Enum that is the same as an existing built-in Enum? And then pass such values as Integers instead of as the Enum type?

Because it is much simpler to use and much better than ordinary integer values. Does that explain?
