Stop Plugin from showing updates

Arpi    PHP, PHP & PHP Framworks, Tips, Tips, wordpress     stop update, stop wordpress update

While developing WordPress site most of the time we use different plugin for the better support of the site.And some times we as a developer make some customization in the default plugin files for our required functionality.

The plugin files are always get updated from its developer and the updates for newer version are notified to us by the wordpress. Suppose we have make some customization in code in the original plugin’s file then that changes will be removed if we update the plugin file to newer version.So to solve this problem we have to stop the automatic update option of the plugin or update notification of the plugin.

To do this we can have two Methods.
That are,

Method 1:

just add below code to the function.php file of your current theme ,

# 3.0:
remove_action( 'load-update-core.php', 'wp_update_plugins' );
add_filter( 'pre_site_transient_update_plugins', create_function( '$a', "return null;" ) );

if you are using wordpress 3.0 or higher version.

What’s the need of using encapsulation { do..while(0) block } in define a macro in C programming?

JIGAR PATEL    c, Tips     encapsulation with macro

While reading many codes in c programming based open source project i came to know one interesting things. Let me explain you by some sample code.

#define Assert(v)   if(!(v)) printf("Error occurred at: %s, in %s at %i",  #v, __FILE__, __LINE__);

At most of the experienced people used to write such macro in following style

 #define Assert(v)   do { if(!(v)) printf("Error occurred at: %s, in %s at %i",  #v, __FILE__, __LINE__); } while(0)

This method is called as making encapsulating our macro.

One Superb thing i learn today is  Short-circuiting in C Programming Expressions. 

Let me explain you by code

#include <stdio .h>
int main() {
   int a = 0;
   int b = 1;
   int c = 2;
   int d = 3;
   a = ++b && ++c || ++d;
   printf ("b = %d,  c = %d, d = %d, a = %d", b, c, d, a);
   return 0;
}</stdio>

if you think output of this program will be

b = 2, c = 3, d = 4, a = 1

In embedded domain, Copying of structure is why avoided in c programming?

JIGAR PATEL    c, Tips     c programming in embedded system

Generally  In embedded software domain for copying structure of same type people dont prefer to use direct assignment and do that by memcpy function or by doing assignment of each element of structure.

Look at Example

struct student {
int roll_no;
int age;
};

struct student exmple1 = {32,15};
struct student exmple2;

for copying exmple1 into exmple2.. instead of writing direct

exmple2=exmple1;

people like to use

memcpy(exmple2,exmple1,sizeof(struct student));

or

exmple2.roll_no=exmple1.roll_no;
exmple2.age=exmple1.age;

Why?

How to change the buffering option for any specified stream in c programming?

JIGAR PATEL    c, Tips    

Many of  us faced this problem. Sometimes we put some debug prints in our code this way

fprintf(logfile,"successfully reached at debug-point 1\n"); 
 
some code is here
 
fprintf(logfile,"successfully reached at debug-point 2"); 
 
Here segmantaion fault occur due to some reason

Now in this condition only debug-point1 will be print on logfile debug-point 2 print was written to buffer to be used for I/O operations with the specified stream logfile.  but its not flushed because it didnt get \n  and not written on logfile and program crash  so we thinks that crash occur after debug-point1

Multi-tasking on Android based devices

saurabh    Android, Tips     Multi-tasking on Android

Cornerstone is an extension to the Android Framework, created by Onskreen, enabling true multi-tasking on Android based devices.

Story behind Cornerstone

As Android exploded and it grew to be used on tablets, the user experience did not evolve to support the richness of the larger screen devices. By default, the user experience designed for 3″ devices were simply blown up to fit on 7 and 10 inch screens. This didn’t take advantage of the larger screen size in any meaningful way, there was just so much more these devices could do.

We created Cornerstone so that Android would truly be optimized for these larger screens and users could multi-task the way they have become used to. Cornerstone was open sourced in Feb 2012.

 While developing you own theme many times you don’t want to use the default search of the wordpress and you want your own search option which looks better and suits your site design.So if you want to insert your own search option in the theme instead of the default search its very easy to implement it.

Now lets do that in the wordpress theme,

First of all add one function in the functions.php file in your theme folder.

This function creates your search view.And add it to the wordpress site where ever you want.

So lets define that function in functions.php file,

function custom_search_form() {
?>
<form method="get" class="" action="<?php bloginfo('home'); ?>/">
<p>
 
<input type="text" value="" name="s" id="s"  />
