Create a Simple WPF application

Windows Presentation Foundation (WPF) is a new graphical subsystem for rendering user interfaces in windows based application developed in Visual Studio. WPF is a next generation presentation system for building windows client applications. WPF should be very familiar if you have previously built applications with .NET Framework using ASP.NET and Windows Forms.

XAML is a declarative XML based language that is used for initializing structured values and objects. When used in WPF, XAML is used to describe visual user interfaces. WPF allows for the definition of both 2D and 3D objects, rotations, animations, and a variety of other effects and features.

These simple steps can be followed to create a new WPF application:
  1. Start Visual Studio "the version you have".
  2. From the menu bar go to File>>New>>Project. A dialog box will appear.
  3. From the drop down list you can select the framework in which you want to work. In the left side pane expand Visual C#, and then select Windows.

    Select new WPF application template as a new project
  4. There is a middle pane including a list of templates. Select WPF Application template.
  5. You can specify a name and location for the project in the Name and Location textbox respectively.
  6. Click OK and MainWindow of the new project will appear.

    The default UI environment of new WPF application

A new project has been created with some files like other project. A file named MainWindow.xaml is already open as in our above screenshot, it will be shown first when launching the application. App.xaml is central starting point, can be used to change the first window.

You can run the application now to see the empty window because our XAML code consists nothing to show. To show a simple message “My First WPF Application”, we have to write the following code in between the Grid panel.
<TextBlock Text="My First WPF Application"></TextBlock>

Run the application now and our message is displayed in the top left corner of the window. We have used a single Text property of the Text block and that is it.
WPF first message shown when run the application

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 …
