it is used to allow the user for selecting a value with in the range.c# win forms supports two types of scroll bars,one is h scroll bar and another one is v scroll bar.in h scroll bar minimum and maximum and value are there.and v scroll bar small change and large change are there.

to do:add a windows forms application and provide a meaning full name.for ex cs316 color picker.design the form as per the requirement.inthis three labels and one group box 1 and one button 1,label 1,label 2,label 3,and group box 1 in this picture box here.and lower side button 1.
Radio button control:it is used to allow the user for selecting a value with in group of related radio button controls.properties:checked:returns true if the radio button is selected else returns false.


observation:when ever a control is placed on the form then they share a special relation ship and with in a single containment only one radio button control can be selected.in asp.net web forms name,sex,qualification and final submit button is there.in sex group name  male ,female.in qualification  inter,degree,and other.bye default all controls can be selected to avoid group name property should be used.in c# web form same as asp.net but this is form.
check box control:it is used for selecting a Boolean value i.e.,true or false .

properties:checked:returns true if the check box is selected.todo:add a windows form and design the form as per the requirement.label,checkbox and two buttons.one is submit button and another one is close button.To execute any specific windows form:open solution explorer,open program.cs file,replace the form name with the form to be executed.
Arrays:it is used to maintain a list of values of similar datatypes.c # supports three types of arrays one is single dimensional array:it is used to maintain a list of values in continuous memory location of same data type.observation:arrays can be declare and initialize directly.to do:add a windows form and design the form as per the requirement.observation:and second one is multi dimensional array:it is used to maintain the values of same data type in rows and columns.limitations of multi dimensional array:the size of the array variable is fixed in multi dimensional array.observation:since the size is fixed the memory blocks will be wasted if the elements are not filled with in the blocks.solution from c #:jagged arrays:it is used to define an array with a variable  column size.
