How to Use Calendar Control: WPF

To select a date in our client application, enter the date into a textbox and then convert it to the particular class i.e. DateTime. What, if there is an in-built control to select a date, month and a year also. Calendar control is used to do these task and look like the following:

Display Modes of Calendar Control in WPF

The image shows three display modes of this calendar control i.e. month, year and decade respectively. By default it is Month view (the first view). User can switch the view to click on month and then year and so on. It have some commonly used properties which are:

DisplayDate: To specify the displayed date in the calendar control. Assign the date in the system date format.

SelectedDate: change the currently selected date. Used as the display date. If the control shows the old date we can change it to current using following code:
<Calendar SelectedDate="{x:Static sys:DateTime.Now}"/>

SelectionMode: it provides multiple modes for selection like “MultipleRange”. We can select a range of dates by using this property.

BlackoutDates: this control provides a feature of black out some dates means user cannot select some of the date blocked by system.
<Calendar>
<Calendar.BlackoutDates>
<CalendarDateRange Start="08.04.2013" End="08.04.2013"/>
<CalendarDateRange Start="08.16.2013" End="08.24.2013"/>
</Calendar.BlackoutDates>
</Calendar>
It will cross all the dates specified in the above range as shown in the following image:

DisplayMode: to change the display modes i.e. year, month and decade as in our first diagram.

Like other controls it also have many events like selectedDatesChanged, displayDateChanged, displayModeChanged and etc. We can specify the actions to be performed at the particular event. Calendar control can be customizable as per the requirement of the user like background and foreground.

difference between structure and union in C Language

In c language article we will see the difference between union and structure. Both are the user define datatype in c language. See the table which is mentioned below: ASP.NET Video Tutorial Series Structure Union1.The keywordstruct is used to define a structure 1. The keyword union is used to define a union. 2. When a variable is associated with a structure, the compiler allocates the memory for each member. The size of structure is greater than or equal to the sum ofsizes of its members. The smaller members may end with unused slack bytes. 2. When a variable is associated with a union, thecompiler allocates thememory by considering the size of the largest memory. So, size of union is equal to the size of largest member. 3. Each member within a structure is assigned unique storage area of location. 3. Memory allocated is shared by individual members of union. 4. The address of each member will be in ascending order This indicates that memory for each member will start at different offset v…

Difference between Linear search and Binary Search in c language

SQL Video Channel : Download all SQL Video



Binary Search Linear Search Works only on sorted items. such as  1,2,3,4,5,6  etc
Works on sorted as well as unsorted items. 12,4,5,3,2,1 etc Very efficient if the items are sorted Very efficient if the items are less and present in the beginning of the list. such as Suppose your list items are : 12,3,4,5,1 and you want to search 12 number then you get beginning in the list. Works well with arrays and not on linked lists. Works with arrays and linked lists.
Number of comparisons are less More number of comparisons are required if the items are present in the later part of the array or its elements are more.

Memory representation of Linked List Data Structures in C Language

Memory representation of Linked List

             In memory the linked list is stored in scattered cells (locations).The memory for each node is allocated dynamically means as and when required. So the Linked List can increase as per the user wish and the size is not fixed, it can vary.

               Suppose first node of linked list is allocated with an address 1008. Its graphical representation looks like the figure shown below:


      Suppose next node is allocated at an address 506, so the list becomes,



  Suppose next node is allocated with an address with an address 10,s the list become,


The other way to represent the linked list is as shown below:




 In the above representation the data stored in the linked list is “INDIA”, the information part of each node contains one character. The external pointer root points to first node’s address 1005. The link part of the node containing information I contains 1007, the address of next node. The last node …
