  3. Coordinate Systems With Visual Studio, any object, whether it is a form or a label uses the same coordinate system. The top left corner, or the originis 0, 0. The bottom right corner is the width and height of the control (in this case, the label). 0, 0 Width, Height

  4. Coordinate Systems • The default coordinate system is made up of rows and columns of pixels. • The pixels are the smallest points you can locate on the form.

  5. Coordinate Systems As you increase the x, you move across to the right. As you increase the y, you move down. x = 50 (0, 0) (50, 50) Y = 50

  6. Coordinate Systems • You can also indicate the width of the object by using its Widthproperty. • Likewise you can indicate the height of the object using its Heightproperty. 0, 0 lblDraw.Width lblDraw.Height

  7. Coordinate Systems To indicate the form’s heightmaxHeight= Me.Height To indicate the form’s widthmaxWidth= Me.Width You can use the Height and Width properties to setrelative positions. Form’s Width and Height

  8. Summary • Vocabulary • Origin • Coordinate System • Width Property • Height Property • Code • MaxHeight = Me.Height • For a form • MaxHt= lblDraw.Heigth • For a label • MaxWidth = Me.Width • For a form • MaxWidth = lblDraw.Width • For a label

  9. Conclusion This PowerPoint provided an overview of coordinate systems in Visual Studio.
