Extreme Urgent - Zoom like in Ms-Word

Hi,
I have to implement the feature of Zoom -like it is there in Ms-Word, Excel etc. in my project.
I am using a MDI form which is always maximized. I have certain forms which gets activated
after selecting some menu options. The point here is not zoming the picture But the complete
Internal form which is activated in MDI. So, if user selects 100% its normal but at 120% or 150% ..
its' content view should be zoomed to that and the scroll bar should appear. - Note: Form(s) have some charts and grids.
Hope I am able to clear the point. (Highly appreciated if some-one can help me out).

Thanks in Advance.
