If you've drawn the entities on a picturebox or something, then you have no other way but erasing the text (which is actually a bitmap) and redraw it again.

I recommend you make a designer like VB's form designer or Visio's designer.

There are not many symbols used in ERD. You can make them as user controls (with size/fontsize/fontcolor etc properties) and yor user will add them from a toolbox. Something like Visio.

or, you can crete a generic usercontrol (like VB's Shape control) and your users can add the control from a toolbox and change its shape (circle/rectangle etc) and font/size etc from a properties window.

thanks iPrank..

but i do not have much time because have to present to my lecturer tomorrow..can i hard code it as if user input more than 5 attributes,then d font size will automatically change?because my notation's size is fix,so when user input more than 5 attributes,the text will out of the notation..

You can use the form's/picturebox's TextHeight and TextWidth methods to determine the fontsize you'll need to fit.

You could put an event in the same picturebox that checks its own text length and reduces the font size automatically if it is too long.
