Question: I have a form with a simple calculator with the size 245 x 359.

I currently have a show/hide button for scientific functions.

I want to be able to click a button and have it show the scientific functions.

Answer: 
In your button click event you can do the following:

```
this.Size = new Size(300,400);

```
In your button click event, set each scentific function to:

```
btnMC.Visbile = true;
btnMC.Size = new Size(300, 400);
btnMR.Visbile = true;
btnMR.Size = new Size(300, 400);
ect...

```

That should do the trick. You might want to considered resizing your form when they click the button as well.
