The System Cannot Execute The Specified Program C++

leoganda — Tue, 25 May 2010 16:31:38 +0000

Today I made a simple console application using Visual C++ 2008 and it was runs well on my development machine. But the problem occurred when I run the application on another machine, the error says “The system cannot execute the specified program“. I was guessing the problem occurred because of missing library or something, after short analysis both machine have the correct and the same library. So what’s going on??

I googled for this error and found this article, it explains how this problem occurred on compiled C++ application. There’s two type of build on VC++ ( Debug and Release), my application was built in debug mode and we can’t re-distribute the application on debug mode. The built program in debug mode only runs on development machine, so in order to distribute my app I should build my application in ‘Release’ mode. Time to switch from ‘Debug’ to ‘Release’ mode,

Open your Visual Studio->(Open Project)->Project->(project name) properties

select the Build Tab, in configuration option choose “Release”.

Rebuild your project, you will find “Release” folder, your released application is in there.

Simple Powershell FTP

leoganda — Mon, 03 May 2010 15:36:51 +0000

With Powershell we can do FTP transaction really easy. The best feature from Powershell is we can use any dll library in our script, we can import .Net libraries and etc into our script. The script below is simple FTP to upload file to FTP server. In this script I’m using System.Net.WebClient to handle the file transfer.

$ftpuser = "user"
$ftppass = "12345"
$ftpserver = "localhost"
$file = "C:\test.txt"
$filenewname = "test.txt"
 
$webclient = New-Object System.Net.WebClient
$ftp = "ftp://"+$ftpuser+":"+$ftppass+"@"+$ftpserver+"/"+$filenewname
$uri = New-Object System.Uri($ftp)
 
$webclient.UploadFile($uri,$file)

Powershell script sort list file

leoganda — Mon, 03 May 2010 15:27:09 +0000

It’s pretty easy to sort an output from ls or Get-ChildItem using powershell, you can sort the output by name, length, and date.

Sort By Name

Get-ChildItem C:\ | sort -property Name

Sort By Size

Get-ChildItem C:\ | sort -property Length

Sort By Date Modified

Get-ChildItem C:\ | sort -property LastWriteTime

You also can reorder the sort output with “-descending”
example :

Get-ChildItem C:\ | sort -property LastWriteTime -descending

Python for Windows Mobile

leoganda — Wed, 24 Feb 2010 10:47:35 +0000

Hello, right now I’m doing development some project using Python for my new company I’m working on. I thought Python will be boring, but Python changes my mind! As programming language Python is really simple and powerful. It can be run cross platform without compile anywhere. It runs well on my Windows and Linux, so I was thinking could I install Python on my Windows Mobile device? The answer is YES! I’m using Windows mobile 6.1 and runs Python perfectly on it. If you want to install Python CE on your windows mobile device, you can get the CAB file in here. It’s free.

Setup was unable to open information file setupqry.inf

leoganda — Mon, 07 Dec 2009 04:42:27 +0000

Hi there, today I was trying to install IIS on my local computer and I got an error “Setup was unable to open information file setupqry.inf Contact your system admin. The specific error code is 0×2 at line 0“.

This problem occured after I upgrade my Windows XP SP2 to SP3.

The error showed up because some file are missing when system upgraded to SP3. Here’s the list of missing file.

setupqry.inf optional.inf msnmsn.inf

setupqry.dll msgrocm.dll ocmsn.dll

Paste those inf file to your Windows\inf directory and paste the dll file to windows\system32\setup. It’s fix my problem.

You can download those file here, just extract it to your windows directory.

Auto Post Using Javascript

leoganda — Sat, 05 Dec 2009 12:37:05 +0000

Hi there, a few weeks ago I was doing research about auto post from webpage to paypal payment page. The basic idea is the visitor fill the form, then when the visitor submit the form we will store visitor data input to database. Once data stored in database the page will be automatically redirected to paypal website. It’s pretty easy, we will use JavaScript to do auto post. I wanna make this article as simple as possible, I just wanna show how to do auto post with Javascript.

1. Database

We will use simple database for this experiment, single table with 4 columns ( id, first_name, last_name, package).

CREATE TABLE `javascriptpost`.`sales` (
`id` INT( 6 ) NOT NULL AUTO_INCREMENT ,
`first_name` VARCHAR( 30 ) NOT NULL ,
`last_name` VARCHAR( 30 ) NOT NULL ,
`package` VARCHAR( 10 ) NOT NULL ,
PRIMARY KEY ( `id` )
) ENGINE = MYISAM ;

2. Form (index.php)

First we need a basic form for user to input, data will be posted to post.php.


	
								
				
				First Name
				
				
				
				Last Name
				
								
				
				Package

3. Post.php

In post.php we will retrieve the posted data from index.php and store the data to database.
Once data stored, the pages will be redirected to paypal website.

We will use javascript syntax to do autopost,

<script language="JavaScript">
var time = null
function subm() {
document.getElementById('paypal').submit();
}
script>

post.php

 

if ( isSet($_POST['first_name']) )
{
	$firstname=$_POST['first_name'];
	$lastname=$_POST['last_name'];
	$package=$_POST['package'];
 
	switch($package)
	{
		case "A": $amount=10;break;
		case "B": $amount=20;break;
		case "C": $amount=30;break;
		default : $amount=0;
	}
 
	$sql = "INSERT INTO sales (first_name,last_name,package) values ('$firstname','$lastname','$package')";
	$con = mysql_connect("localhost","root","");
	if (!$con)
	  {
	  die('Could not connect: ' . mysql_error());
	  }
 
	mysql_select_db("javascriptpost", $con);
	mysql_query($sql);//insert to database
}
?>

            	Thank you for booking                
                Now we will redirect to payment page            
            
				
					    
						
						 echo $package;?>">
						 echo $amount;?>">

Solving Zend Framework error “An Error Has Occurred A project profile was not found”

leoganda — Thu, 15 Oct 2009 02:39:22 +0000

Hi there, I had an error “An Error Has Occurred A project profile was not found” on Zend framework command line when I tried to generate an action for my project. I’m using Windows XP and for the web server I’m using XAMPP. The “An Error Has Occurred A project profile was not found” happened because we have wrong include path in our php.ini.

Open your php.ini and find the include_path line, insert your zend framework library path into the line before the PEAR path.

include_path = ".;E:\xampp\htdocs\ZendFramework\library;E:\xampp\php\PEAR"

Save the file and restart your Apache. Good luck

XML-RPC on IPhone

leoganda — Tue, 25 Aug 2009 12:38:18 +0000

Hi, after play along to implement XML-RPC on IPhone finally I made it. I tried googling to find some articles that related to XML-RPC on IPhone, and those article drag me to WordPress application for IPhone. This application using XML RPC to communicate IPhone with the WordPress Blog, so the idea is grab the XML-RPC function from the WP application and implement it on our application. First we need to download WordPress for IPhone source code, you can download it here.

Once you download the source code, extract it. You will find a folder named Class, under the Class folder you will find XMLRPC folder. We need to import this folder (with the file inside) to our project, and also import NSString+XMLExtensions.h and NSString+XMLExtensions.m.

I will show you how to implement this XML-RPC on simple application.

Start your XCode program, make new “View-based Application” project.

Name the project with “XMLRPC-sayHello”.

Once the workspace opened, import the XMLRPC folder from WordPress source code to our project. Right click on Class folder, Add->Existing files

Then browse to the WordPress for Iphone source code, and select the XMLRPC folder. Click the “Add” button. The next is import the NSString+XMLExtensions.h and NSString+XMLExtensions.m files to our project.

Your project files will be look like this.

Ok the import step is done, now we need to design UI. We will make a simple interface with Label and Button only. The final design will be look like this.

To design the UI, double click the XMLRPC_SayHelloViewController.xib file and the interface builder will show up. On interface builder Drag a label from the library and change the text to “Response”. Next drag the Round Rect Button, and change the text to “Get Response”. Once done, close the interface builder and back to XCode.

Coding

Open the XMLRPC_SayHelloViewController.h, we will import the header files that used for XMLRPC, that are XMLRPCResponse.h, XMLRPCRequest.h, and XMLRPCConection.h. We also declare the label and the getResponse method in our header file. It should be look like this.

Once you done with the XMLRPC_SayHelloViewController.h, double click the XMLRPC_SayHelloViewController.xib to reopen the interface builder, we will connect the code with the interface. Open the Inspector window first Tools->Inspector.

Click the Response label in designer, then in the Inspector window it will be shown “New Referencing Outlet”. Drag the right circle of “New Referencing Outlet” to File’s Owner. See image.

When you release the mouse button, choose the “lblResponse” from the pop up window.

Ok, now select the Button on the interface, and drag the right circle button on the “Touch Down” inspector window to File’s Owner.

Once you finished editing the interface, save it and we continue with the coding.

Open the XMLRPC_SayHelloViewController.m and add the following code.

You can change the server path to your own path, and don’t forget to enable the XMLRPC on your wordpress installation. On wordpress XMLRPC there is demo.sayHello method that returns “hello” string, so I used this for the example.

Tadda! It’s done! Run the emulator by pressing command+enter button. Once running, press the “Get Response” button, that will invoke the getResponse method and show up the result to lblResponse.

How to enable XAMPP SSL socket transport

leoganda — Sun, 26 Jul 2009 13:37:06 +0000

Hi today I have an experiment with GData in Zend Framework PHP , and found an error that my XAMPP prevent SSL socket transport and return this error.

Fatal error: Uncaught exception 'Zend_Gdata_App_HttpException' with message 'Unable to Connect to ssl://www.google.com:443. Error #24: Unable to find the socket transport "ssl" - did you forget to enable it when you configured PHP?'

Here’s the solution to make your XAMPP support socket transport SSL.
1. First stop your Apache service
2. Find libeay32.dll and ssleay32.dll in xampp\php\ folder, and copy it into xampp\apache\bin\ folder. Just overwrite the older files in there.
3. Edit php.ini file in xampp\apache\bin, remove the semicolon in “;extension=php_openssl.dll”
4. Start the Apache service

That’s it, your SSL transport socket in your XAMPP has been activated.

How to connect MySQL in Prado Framework

leoganda — Sat, 18 Jul 2009 16:00:55 +0000

Hello!

This is my first article tutorial in this blog, today my friend have a problem connecting SQL databases with PRaDO framework. I have used this framework several years ago, and it’s quite easy to make a website with Prado. This time I will write how to connect MySQL with Prado, insert data, and display it in the web page.

First, I’m using XAMPPLITE as webserver, XAMPPLITE is lite version of XAMPP, but if you are using XAMPP it’s ok. Download XAMPP.

After you finish the XAMPP download, continue with download Prado framework. Download Prado.

Install the XAMPP, and extract the prado framework in htdocs folder.

The optional prado-cli.php PHP script file in the framework directory provides command line tools to perform various tedious takes in Prado. The prado-cli.php can be used to create Prado project skeletons, create initial test fixtures, and access to an interactive PHP shell. We will use command line tool to generate our prado project.

1. Make setPath

First I made setpath.bat to declare PHP path, so we can called any file in PHP path easier.

Make a file setpath.bat ( I put this file in C:\)

PATH=C:\xampplite\php\;

set the path to your php directory.

2. Generate the Project

Open the command prompt, and execute the setpath.bat by typing the filename setpath.bat

Go to htdocs

Let’s generate project, execute this line

php C:\xampplite\htdocs\prado\framework\prado-cli.php -c pradocontact

When the generate success the command line will display line like this

3. Open in browser

Open your browser and navigate to http://localhost/pradocontact/ if you see the prado welcome page, congratulations you have been generate prado project successly.

4. Create Database

Navigate to http://localhost/phpmyadmin/ and create new database. Type “pradocontact” in create new database field and hit create button.

Then make a new table called “contact” with 2 field (id and name). Set the id field type into tinyint, auto_increment, and as primary key. Set the field name type as varchar and give the length 100.

 
CREATE TABLE `contact` (
`id` TINYINT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`name` VARCHAR( 100 ) NOT NULL
) ENGINE = MYISAM ;
 
After the TABLE created, INSERT 2 rows DATA INTO contact TABLE.
INSERT INTO `contact` ( `id` , `name` )
VALUES (
'1', 'leo'
), (
'2', 'ganda'
);

5. Set connection in application.xml

Browse your project folder and open the protected folder C:\xampplite\htdocs\pradocontact\protected

You will see a file “application.xml”, open it and edit.

>
 
	 id="db" class="System.Data.TDataSourceConfig">
     ConnectionString="mysql:host=localhost;dbname=pradocontact" username="root" password=""/>
  	>
 
  	 class="System.Data.ActiveRecord.TActiveRecordConfig" ConnectionID="db" />
>

We make a ConnectionString to mysql database, dbname is our database that used for this project. Set the username and password with your database account.

6. Create Active Record

To use active record, I will make a new folder called database inside the protected folder to store the ActiveRecord file. After the database folder created, open the application.xml once again, and declare the database path.

>
   namespace="Application.database.*" />
>

Your application.xml should be look like this

 version="1.0" encoding="utf-8"?>
 
 id="pradocontact" mode="Debug">
   >
   namespace="Application.database.*" />
  >
 
  
 >
	 id="db" class="System.Data.TDataSourceConfig">
     ConnectionString="mysql:host=localhost;dbname=pradocontact" username="root" password=""/>
  	>
  	 class="System.Data.ActiveRecord.TActiveRecordConfig" ConnectionID="db" />
  >
 
 
  
  >
     id="page" class="TPageService" DefaultPage="Home" />
  >
 
  
>

After you finish editing the application.xml, let’s generate Active Record from our database in MySQL.
Open the command prompt again, go to C:\xampplite\htdocs\pradocontact\ and execute php C:\xampplite\htdocs\prado\framework\prado-cli.php shell .

execute generate contact Application.database.ContactRecord

Open your database folder with explorer, and you will find a new file called ContactRecord.php, try to open it.


/**
 * Auto generated by prado-cli.php on 2009-07-18 03:01:37.
 */
class ContactRecord extends TActiveRecord
{
	const TABLE='contact';
 
	public $id;
	public $name;
 
	public static function finder($className=__CLASS__)
	{
		return parent::finder($className);
	}
}
?>

7. Test The Active Record

Ok, let test our Active Record using command line tools, type “ContactRecord::finder()->findAll()” and hit enter. See the image below.

The command line return an array with 2 record from the mySQL database and that means our activeRecord running well!

8. Edit Home.page

paste this code on your Home.page file
<%@ Title="Contact List" %>


Contact List

Create New Contact




DataKeyField="id"

AutoGenerateColumns="false"

>

HeaderText="ID"

DataField="id" />

HeaderText="Name"

DataField="name" />

9. Make new file Home.php

Paste this code on your Home.php


class Home extends TPage
{
    /**
     * Populates the datagrid with user lists.
     * This method is invoked by the framework when initializing the page
     * @param mixed event parameter
     */
    public function onInit($param)
    {
        parent::onInit($param);
        // fetches all data account information
        $this->UserGrid->DataSource=ContactRecord::finder()->findAll();
        // binds the data to interface components
        $this->UserGrid->dataBind();
    }
}
?>

10. Make a new file insert.page

<%@ Title="Insert Contact" %>



Insert Contact

Name:

11. Make a new file insert.php

class insert extends TPage
{
 
    public function createButtonClicked($sender,$param)
    {
        if($this->IsValid)  // when all validations succeed
        {
            // populates a UserRecord object with user inputs
            $ContactRecord=new ContactRecord;
            $ContactRecord->name=$this->Name->Text;
 
 
            // saves to the database via Active Record mechanism
            $ContactRecord->save();
 
            // redirects the browser to the homepage
            $this->Response->redirect($this->Service->DefaultPageUrl);
        }
    }
}
 
?>

Navigate your browser to http://localhost/pradocontact/ you will see this page

Ok, thanks for reading. Have a nice day!
