How to get screen resolution in case of using multiple monitors ?

(Super Coder) — Tue, 16 Dec 2008 10:30:42 +0900

You can simply get the total number of monitors byScreen.MonitorCount.
If you have dual monitors, the return value of Screen.MonitorCount is 2.
Screen.Monitors[ index ] has the properties related with your multiple monitors.

Here's the simple example which measure the full screen resolution for multiple monitors.

//
// Programmed 2008 by Kurapa Chunun Kang (kurapa@kurapa.com)
//
// http://kurapa.com
//
functionGetScreenResolution: TRect;
var
i: Integer;
r, n: TRect;
begin
// initialize returning value
r.Left := 0;
r.Right := 0;
r.Top := 0;
r.Bottom := 0;

for i := 1 to Screen.MonitorCount do
begin
n.Left := Screen.Monitors[i-1]WorkareaRect.Left;
n.Right := Screen.Monitors[i-1].WorkareaRect.Right;
n.Top := Screen.Monitors[i-1].WorkareaRect.Top;
n.Bottom := Screen.Monitors[i-1].WorkareaRect.Bottom;
if r.Left>n.Left then r.Left := n.Left;
if r.Right<n.Right then r.Right := n.Right;
if r.Top>n.Top then r.Top := n.Top;
if r.Bottom<n.Bottom then r.Bottom := n.Bottom;
end;

Result := r;
end;

// In case of clicking button, window size is changed to the full resolution.
procedure TForm1.Button1Click(Sender: TObject);
var r: TRect;
begin
r := GetScreenResolution;
Left := r.Left;
Top := r.Top;
Width := (r.Right-r.Left);
Height := (r.Bottom-r.Top);
end;

Remote Desktop not work after SP3 installation ?

How to turn off monitor ?

(Super Coder) — Wed, 10 Dec 2008 15:57:08 +0900

If you want, you can turn off or turn on the monitor power. Try it:

SendMessage(Application.Handle, WM_SYSCOMMAND,SC_MONITORPOWER, 0);

or

SendMessage(Application.Handle, WM_SYSCOMMAND, SC_MONITORPOWER, 1);

How to set and get sessions on JSP code ?

(Super Coder) — Mon, 27 Oct 2008 14:13:16 +0900

Here's the simple example to set and putsessions.

save_my_name,jsp

<%
String name = request.getParameter( "username" );
session.setAttribute( "theName", name );
%>
<HTML>
<BODY>
<A HREF="next_page.jsp">Continue</A>
</BODY>
</HTML>

save_my_name.jsp saves the user's name in the session, and puts a link to another page, next_page.jsp.
next_page.jsp shows how to retrieve the saved name.

next_page.jsp

<HTML>
<BODY>
Hello, <%=session.getAttribute( "theName" ) %>
</BODY>
</HTML>

How to add a declaration on JSP code ?

(Super Coder) — Mon, 27 Oct 2008 14:07:15 +0900

If you have developed C or C++ program, you may know below examples.

// printf( "a.out");

/*
printf( "b.out");
*/

Above code have no bug, but no code will be compiled, because it's alldeclarations.

In JSP, you can make declarations as well. In some documents, a declarations is also called asremark.

To add a declaration, you must use the <%! and %> sequences to enclose your declarations, as shown below.

<%@ page import="java.util.*" %>
<HTML>
<BODY>
<%!
Date theDate = new Date();
Date getDate()
{
System.out.println( "In getDate() method" );
return theDate;
}
%>
Hello! The time is now <%= getDate() %>
</BODY>
</HTML>

Above code is actuallydead code, because it;s surrounded with <%! and %>.

How to include file in JSP ?

(Super Coder) — Mon, 27 Oct 2008 14:01:31 +0900

Just like ASP, or PHP, JSP is also allow toinclude for programmer by include function.
Here's the simple example.

<HTML>
<BODY>
Going to include hello.jsp...<BR>
<%@include file="hello.jsp" %>
</BODY>
</HTML>

How to print out text strings on HTML directly ?

(Super Coder) — Mon, 27 Oct 2008 13:48:40 +0900

InJSP, you can print out text strings by out.println().

Here's the example.

<HTML>
<BODY>
<%
  // This scriptlet declares and initializes "date"
  System.out.println( "Evaluating date now" );
  java.util.Date date = new java.util.Date();
%>
Hello!  The time is now
<%
  // This scriptlet generates HTML output
  out.println( String.valueOf( date ));
%>
</BODY>
</HTML>

But above example can be expressed as below.

<HTML>
<BODY>
<%
// This scriptlet declares and initializes "date"
System.out.println( "Evaluating date now" );
java.util.Date date = new java.util.Date();
%>
Hello! The time is now <%= date%>
</BODY>
</HTML>

Both ways shows the same result, but the second is much faster and have good readability than the first. code,

Clipboard copy function working

(Super Coder) — Fri, 17 Oct 2008 13:28:56 +0900

When copying trackback address or shortcut url on the articles, clipboard function is really useful.
But there are some compatibility issue in browsers.

I checked below function is working on Microsoft Internet Explorer. For supporting Firefox, you need to find another solution.

function copy_clip(meintext){
    if (window.clipboardData) { 
        // the IE-manier
        window.clipboardData.setData("Text", meintext);
        // waarschijnlijk niet de beste manier om Moz/NS te detecteren;
        // het is mij echter onbekend vanaf welke versie dit precies werkt:
    } else if (window.netscape) {
        // dit is belangrijk maar staat nergens duidelijk vermeld:
        // you have to sign the code to enable this, or see notes below
        netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect');

        // maak een interface naar het clipboard
        var clip = Components.classes['@mozilla.org/widget/clipboard;1'].createInstance(Components.interfaces.nsIClipboard);
        if (!clip) return;

        // maak een transferable
        var trans = Components.classes['@mozilla.org/widget/transferable;1'].createInstance(Components.interfaces.nsITransferable);
        if (!trans) return;

        // specificeer wat voor soort data we op willen halen; text in dit geval
        trans.addDataFlavor('text/unicode');

        // om de data uit de transferable te halen hebben we 2 nieuwe objecten nodig om het in op te slaan
        var str = new Object();
        var len = new Object();

        var str = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);

        var copytext=meintext;

        str.data=copytext;

        trans.setTransferData("text/unicode",str,copytext.length*2);

        var clipid=Components.interfaces.nsIClipboard;

        if (!clip) return false;

        clip.setData(trans,null,clipid.kGlobalClipboard);
    }

    var msg = alert_msg['url_copy'];
    if(typeof(msg)=='undefined'||!msg) return;
    alert(msg);
}



Usage sample

<a href=# onclick='copy_clip( "http://kurapa.com"); return false;'>http://kurapa.com</a>

Find File at certain directory in Delphi

(Super Coder) — Fri, 10 Oct 2008 13:08:32 +0900

This function we show below receives as parameters a file specification (like for example 'C:\tmp\*.tmp' or 'C:\*' if you want to search the entire hard disk.) and optionally a set of attributes (exactly as Delphi'sFindFirst function), and it returs a StringList with the full pathnames of the found files. You should free the StringList after using it.

interface

uses SysUtils, Classes;

function FindFile(const filespec: TFileName; attributes: integer
   = faReadOnly Or faHidden Or faSysFile Or faArchive): TStringList;

implementation

function FindFile(const filespec: TFileName; attributes: integer): TStringList;
var
spec: string;
list: TStringList;

procedure RFindFile(const folder: TFileName);
var
SearchRec: TSearchRec;
begin
// Locate all matching files in the current
// folder and add their names to the list
if FindFirst(folder + spec, attributes, SearchRec) = 0 then begin
try
repeat
if (SearchRec.Attr and faDirectory = 0) or
   (SearchRec.Name <> '.') and (SearchRec.Name <> '..') then
list.Add(folder + SearchRec.Name);
until FindNext(SearchRec) <> 0;
except
FindClose(SearchRec);
raise;
end;
FindClose(SearchRec);
end;
// Now search the subfolders
if FindFirst(folder + '*', attributes
Or faDirectory, SearchRec) = 0 then
begin
try
repeat
if ((SearchRec.Attr and faDirectory) <> 0) and
   (SearchRec.Name <> '.') and (SearchRec.Name <> '..') then
RFindFile(folder + SearchRec.Name + '\');
until FindNext(SearchRec) <> 0;
except
FindClose(SearchRec);
raise;
end;
FindClose(SearchRec);
end;
end; // procedure RFindFile inside of FindFile

begin // function FindFile
list := TStringList.Create;
try
spec := ExtractFileName(filespec);
RFindFile(ExtractFilePath(filespec));
Result := list;
except
list.Free;
raise;
end;
end;

Sample call

You can try this function placing a ListBox and a button on a form and adding this code to the OnClick event of the button:

procedure TForm1.Button1Click(Sender: TObject);
var
list: TStringList;
begin
list := FindFile('C:\Delphi\*.pas');
ListBox1.Items.Assign(list);
list.Free;
end;

ASCII Artwork Generator from image file

(Super Coder) — Tue, 23 Sep 2008 07:55:23 +0900

Now a days, we don't useASCII Artwork usually for internet communication, because technology is changing rapidly.

Following snipet is the really great source can generage ASCII Artwork from image file such as jpeg or gif.

<?php
   $filename = $_POST['file'];

   $image = file_get_contents($filename);

   $image = imagecreatefromstring($image);

   $width = imagesx($image);

In case of development in clinet/server application, datetime formation conversion is frequently required.
Following is the simple example for datetime conversion.

private double ConvertToTimestamp(DateTime value)
{
//create Timespan by subtracting the value provided from
//the Unix Epoch
TimeSpan span = (value - new DateTime(1970, 1, 1, 0, 0, 0, 0).ToLocalTime());

//return the total seconds (which is a UNIX timestamp)
return (double)span.TotalSeconds;
}

Retrieve system information

(Super Coder) — Mon, 22 Sep 2008 09:29:02 +0900

When system information is required in application,SystemInformation global instance is very useful.

In case of gettingMonitor Size,Virtual Screen,Computer Name,Keyboard Delay,Network Connection,Power Status, and other system variables, SystemInformation instance is very useful.

Following reference code is the example.

//Namespace reference
using System:

.
.
.

    
Hashtable sysValues = new Hashtable();

sysValues.Add("Monitor Size: ", SystemInformation.PrimaryMonitorSize);
sysValues.Add("VirtualScreen: ", SystemInformation.VirtualScreen);
sysValues.Add("Working Size: ", SystemInformation.WorkingArea);
sysValues.Add("Computer Name: ", SystemInformation.ComputerName);
sysValues.Add("Keyboard Delay: ", SystemInformation.KeyboardDelay);
sysValues.Add(Total Monitors: ", SystemInformation.MonitorCount);
sysValues.Add("Network Connection: ", SystemInformation.Network);
sysValues.Add("Power Status: ", SystemInformation.PowerStatus);

How to search file on certain directory ?

(Super Coder) — Mon, 16 Jun 2008 08:50:59 +0900

In case of finding files on certain directory, you need to useFindFirstFileEx function.

Following example shows the example,

bool KFindFile(void *findname)
{
WIN32_FIND_DATA FindFileData;
HANDLE hFind;

CString strSearch = (LPCTSTR)findname;

hFind = FindFirstFileEx( strSearch, FindExInfoStandard, &FindFileData, FindExSearchNameMatch, NULL, 0);
if (hFind==INVALID_HANDLE_VALUE)
{
MessageBox( NULL, CString("Invalid Handle Value"), CString("Error"), MB_OK);

return false;
}
else
{
MessageBox( NULL, (LPCTSTR)FindFileData.cFileName, (LPCTSTR)FindFileData.cFileName, MB_OK);

FindClose( hFind);
return true;
}
}

Above source works on Windows CE Platform as well. And you can use above function as below:

.
.
.
KFindFile( _T("\\My Documents\\My Pictures\\PIC-*.jpg"));
.
.

How to limit by Timeout when opening URL ?

(Super Coder) — Mon, 14 Apr 2008 11:24:25 +0900

Previously, I wrote the example to settimeout forfopen function. But it is not practical way to put timeout, because the configuration data is also modified by that function.

Here's another way to achieve the same function.

$query = "http://kurapa.com/api/?lic=" . $license_key . "&i=" . $ipaddress;
$url = parse_url($query);
$host = $url["host"];
$path = $url["path"] . "?" . $url["query"];
$timeout = 1;
$fp =fsockopen ($host, 80, $errno, $errstr, $timeout)
or die('Can not open connection to server.');
if ($fp)
{
fputs ($fp, "GET $path HTTP/1.0\nHost: " . $host . "\n\n");
while (!feof($fp))
{
$buf .= fgets($fp, 128);
}
$lines = split("\n", $buf);
$data = $lines[count($lines)-1];
fclose($fp);
} else {
# enter error handing code here
}
echo $data;

As you can see above, I used fsockopen function to put timeout.

How to rename(change file name) in C# ?

(Super Coder) — Wed, 12 Mar 2008 10:32:36 +0900

Simplest way to change file name in C# is using File.Move() function.

Here's the simple example change file name for Samsung Black Jack Phone. However it may work on another platform if it supports .NET compact framework.

In addition, File creation time can be obtained by FileInfo class. See the below example for addition example.

{
int iocnt = 100;
DirectoryInfo dir = new DirectoryInfo( strDir);
FileInfo[] bmpfiles = dir.GetFiles("PIC-*.jpg");
Console.WriteLine("Total number of bmp files", bmpfiles.Length);
foreach (FileInfo f in bmpfiles)
{
String fn = fCreationTime.Year + "-"
+ ((f.CreationTime.Month<10) ? "0":"") + f.CreationTime.Month + "-"

How to convert W3C Date Time Format ?

(Super Coder) — Thu, 28 Feb 2008 06:28:22 +0900

When generating RSS, or Sitemap,W3C Date Time Format string is used. In case of using xmlrpc, it contains W3C Date Time Format string conversion module such asw3cdatetime_encode, andw3cdatetime_decode.

If you don't use xmlrpc module, you can declare below module in order to use W3C Date Time Format string conversion module. Of course, if your PHP supports the function, you don't need to declare below functions.

// date helpers - added by kurapa 2008-02-12
function w3cdatetime_encode($timet, $utc=0) {
if (!$utc) {
$t=strftime("%Y-%m-%dT%H:%M:%S", $timet);
} else {
if (function_exists("gmstrftime"))
// gmstrftime doesn't exist in some versions
// of PHP
$t=gmstrftime("%Y-%m-%dT%H:%M:%S", $timet);
else {
$t=strftime("%Y-%m-%dT%H:%M:%S", $timet-date("Z"));
}
}
$t .= "+00:00";
return $t;

Console.WriteLine("Total number of bmp files", bmpfiles.Length);
foreach( FileInfo f in bmpfiles)
{
Console.WriteLine("Name is : {0}", f.Name);
Console.WriteLine("Length of the file is : {0}", f.Length);

Get the actual filesize for a size above 2GB in Windows

(Super Coder) — Sun, 24 Feb 2008 15:46:08 +0900


If you want to get the actualfilesize for a size above 2GB in Windows, you can use theCOM-extensions in PHP.



An example is as follows:

<?
function KFileSize($file)
{
    if (file_exists($file))
    {

        $fsobj = new COM("Scripting.FileSystemObject");

        $file = $fsobj->GetFile($file);

        $var = ($file->Size) + 1 - 1;

            

        return $var;

     }
    else
    {

            // File does not exist

            return 0;
    }
}

?>


This will return the corrent filesize. And it is very useful with
PHP-GTK applications, where you want to use the filesize for larger
files.



This example also works for files over a Windows-network. Try this example with the function:

<?

   echo KFileSize("c:/tmp/foo.mp3");

?>

3) set browser.sessionstore.resume_session_once -> "true"

Restart Firefox, and your done!

ISO 8601 format time format string conversion

(Super Coder) — Wed, 13 Feb 2008 08:43:37 +0900

When communicating with XML,ISO 8601 format time string is used. In case of using xmlrpc, it contains ISO 8601 format time string conversion module such asiso8601_encode, and iso8601_decode.

If you don't use xmlrpc module, you can declare below module in order to use ISO 8601 format time string conversion module. Of course, if your PHP supports the function, you don't need to declare below functions.

// date helpers
function iso8601_encode($timet, $utc=0) {
// return an ISO8601 encoded string
// really, timezones ought to be supported
// but the XML-RPC spec says:
//
// "Don't assume a timezone. It should be specified by the server in its
// documentation what assumptions it makes about timezones."
//
// these routines always assume localtime unless
// $utc is set to 1, in which case UTC is assumed
// and an adjustment for locale is made when encoding
if (!$utc) {
$t=strftime("%Y%m%dT%H:%M:%S", $timet);
} else {
if (function_exists("gmstrftime"))

$t=gmstrftime("%Y%m%dT%H:%M:%S", $timet);
else {
$t=strftime("%Y%m%dT%H:%M:%S", $timet-date("Z"));
}
}
return $t;
}

function iso8601_decode($idate, $utc=0) {
// return a timet in the localtime, or UTC
$t=0;
if (ereg("([0-9]{4})([0-9]{2})([0-9]{2})T([0-9]{2}):([0-9]{2}):([0-9]{2})",
$idate, $regs)) {
if ($utc) {
$t=gmmktime($regs[4], $regs[5], $regs[6], $regs[2], $regs[3], $regs[1]);
} else {
$t=mktime($regs[4], $regs[5], $regs[6], $regs[2], $regs[3], $regs[1]);
}
}
return $t;
}

As I mentioned, above functions will be very useful if you need to implement RSS, or Sitemap.
