need Help on building a GeometryApplication

Question

hi  I m trying to build a geometry application in which upon selection of a figure by a user a seperate window opens for him to punch in the dimension based on these dimensions (ex upon selection of rectangle one has to enter lengthbreadth if a circle is selected then the box should change accepting radius or Diameter)after the dimensions are give the figure is generated and this should be saved as a bitmap 1.>My Q is how do i get this save option i.e how do i save the generated figure as a bitmap 2.>Currently in my application the dimensions are hardcoded into the program I want to make this variable i.e the user should be able to give the dimensions based on these dimensions the figure must be generated. I have already written the code for ellipserectangle and need help regarding the above mentioned problems. please help me regarding this actually any help regarding this would be a great help....this is a software for use by visually Impaired.... thank you cheers!!

thanks for the quick reply mike.... What can i do about the first problem mike... as u know when we are drawing figure like rectangles we define the pen and the dimension... Is there anyways i can make them variable ... in the sense that a user should be able to give the dimensions and based upon the window size and application limitation we can throw an exception if the user iiss attempting to set a size higher than a prescribe limit

to save an object to a bitmap you can paint to a bitmap directly by getting a Graphics handle to it. 1. Create your bitmap --> Bitmap myBitmap = new Bitmap(100 100); 2. Get a graphics handle --> using (Graphics g = Graphics.FromBitmap(myBitmap )) { g.Draw... } 3. Save the bitmap --> myBitmap.Save...
