Flash Skinnable Window

Filed under: Flash/Actionscript at 11:07:52 On 2006-05-31

Well ,

I started Flash/Flex a few dayz back.Got allured with its stronger "RAD" capabilities where you need not dwelve much into CSS and Javascript to make some web based application work for basic functionality and portability across browsers is a bless.

Some projects which i did are already online which includes Flash/Flex based web operating system( Web OS).It can be found @ www.ostype.com.

Other is Web Meet - which is an online meeting and collaborative tool.

Though, not getting much time to complete them ,but they will be fully functional soon ,this i hope cool

Ankur ,Chintan and Pratik have been helping me throughout these projects ,whereever i got stuck these guys have been more than helping to me and sometimes even gave their code.

One here comes from Chintan which is very basic thingy but shows how easy is it to inherit the skinnability to you components.

Why my Win32:Timer code sucks !

Filed under: Visual C++ at 13:05:24 On 2006-05-17

Now i came to know why my precise loops alwayz showed a random behaviour.

Actually i used to call timeGetTime() to do timing control.

But it seems because of the granularity of the system timer can be as high as 10-15
milliseconds, meaning that timeGetTime() is only accurate to 10-15 milliseconds.

There are multiple approaches which we can use for time control, some of them are :


It stands for "Read Time Stamp Counter." This assembly instruction returns
an unsigned 64-bit integer reading on the processor's internal high-precision

In order to get the frequency of the timer (how much the timer return
value will increment in 1 second), you can read the registry for the machine's

bool GetPentiumClockEstimateFromRegistry(unsigned __int64 *frequency)
HKEY hKey;
DWORD cbBuffer;
LONG rc;

*frequency = 0;

rc = RegOpenKeyEx(

if (rc == ERROR_SUCCESS)
cbBuffer = sizeof (DWORD);
DWORD freq_mhz;
rc = RegQueryValueEx
if (rc == ERROR_SUCCESS)
*frequency = freq_mhz*1024*1024;
RegCloseKey (hKey);

return (*frequency > 0);


double GetPentiumTimeAsDouble(unsigned __int64 frequency)
// returns < 0 on failure; otherwise, returns current cpu time, in seconds.
// warning: watch out for wraparound!

if (frequency==0)
return -1.0;

// get high-precision time:
unsigned __int64 high_perf_time;
unsigned __int64 *dest = &high_perf_time;
_emit 0xf // these two bytes form the 'rdtsc' asm instruction,
_emit 0x31 // available on Pentium I and later.
mov esi, dest
mov [esi ], eax // lower 32 bits of tsc
mov [esi+4], edx // upper 32 bits of tsc
__int64 time_s = (__int64)(high_perf_time / frequency);
__int64 time_fract = (__int64)(high_perf_time % frequency);
double ret = (time_s % (60*60*24*7)) + (double)time_fract/(double)((__int64)frequency);
return ret;
return -1.0;

return -1.0;

QueryPerformanceFrequency & QueryPerformanceCounter:

QueryPerformanceFrequency returns the amount that the counter will increment over 1 second; QueryPerformanceCounter


returns a LARGE_INTEGER (a 64-bit *signed* integer) that is the current value of the counter.

This approach is accurate upto 10 micro seconds.tongue-out


If we call timeBeginPeriod(1) at the beginning of our program (and timeEndPeriod(1) at the end), timeGetTime() will usually become

accurate to 1-2 milliseconds.

Sleep() sleeps for goes hand-in-hand with the granularity of timeGetTime(), so after calling timeBeginPeriod(1) once, Sleep(1)

will actually sleep for 1-2 milliseconds, Sleep(2) for 2-3, and so on (instead of sleeping in increments as high as 10-15 ms).

For simple timing, both timeGetTime and QueryPerformanceCounter work well, and QueryPerformanceCounter is obviously more accurate.

Google Suggest - Hack

Filed under: PHP at 04:00:00 On 2006-05-09

You may like to visit this old project of mine.

This tool does not use Google API.

We have gone beyond one step here from Google by recursively calling the function and appending alphabets from A to Z to the query string to get the complete resultset about that keyword.

For example if you put "paper" as a query the result set will be like :

paper 175,000,000 results
paper airplanes 1,830,000 results
paper mache 403,000 results
paper doll heaven 245,000 results
paper dolls 3,120,000 results
paperdoll heaven 19,100 results
paperport 353,000 results
paperdollheaven 1,780 results
paperchase 72,100 results
paper source 21,700,000 results

I used CURL for this project ,but regex can be used more efectively.

Actually i found this script on net a way back and then heavilly modified it as my webHost was not supporting many functions

putting a snippet here for you to think ahead. P.M. me if you need the complete source.

function buildSuggestUrl($keyword)
return "http://www.google.com/complete/search?hl=en&js=true&qu=" . urlencode($keyword);

PHP Eval

Filed under: PHP at 05:36:19 On 2006-05-07

Well ,this is a slower method (100 times slower sometimes) than direct page rendering.

But ,u get total control over the pagecontent dynamically.

Many a times its safe also to secure your PHP code.The immediate application which i could think of after looking at this function is my own template engine.

function eval_new_helper($arr){
return ("echo stripslashes(\"".addslashes($arr[1])."\");");

function eval_new($string){
$string = "".$string."";
$string = preg_replace("/<\?=\s+(.*?)\s+\?>/", "", $string);
$string = str_replace('?>', '', str_replace( array('((.|\n)*?)<\?/","eval_new_helper",$string) ) );
return eval($string);

// call it from here

Faster Web page rendering

Filed under: PHP at 07:32:35 On 2006-05-04

HTML files for larger sites can become pretty large themselves.

Gzipping or compressing these files has shown to provide a reduction in the neighboorhood of 70-80% of the original file size, a fairly significant 'weight loss'. I did the same thing for my site's index.php and to my surprise the page size came down to 11 KB flat from a huge 90 KB generated HTML.

The Trick

What you need to do is put is ob_start ("ob_gzhandler"); on the top of each page !



We use PHP's ob_gzhandler to send compressed data. This function will first check to see if the browser requesting the file will accept 'gzip,deflate' encoding; if not it sends the file uncompressed. Almost all the browsers support GZip compression. One thing to keep in mind is that , Images are not compressed with this method as only HTML code is rendered via server.
