TextBlock Control Introduction: WPF

According to previous post, Label control derives from Content Control and can: display other type of data as well as string, perform all the functions of a content control. There are some drawbacks in label control such as it cannot support multi line texts.

Textblock control is derived from Framework Element, and can display string type of data only. It has a property TextWrapping which is used to display our text in multiple lines. Means text block can be used to display paragraphs in WPF. A textblock can be drawn in XAML code with below line:

<TextBlock Text="text block" Width="200"/>

It will show the above text in the width specified. If we want to show some more text, then we have to use TextWrapping property of this textblock. If we don’t enable text wrapping then it will only show the text that can be shown in specified width.
<TextBlock Text="Textblock control is derived from Framework
Element, and can display string type of data only.
It has a property TextWrapping which is used to
display our text in multiple lines. Means text
block can be used to display paragraphs in WPF"
Width="200" TextWrapping="Wrap"/>

Now when we run this code, it will show the text written above. The width will be fixed as 200 and height will be increased according to the given text.

If we also specified height here, then the text will not be shown. Just placed the height as 200 here and check out the output as:

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 …
