Powerbuilder Function

In every modern programming languages, there is a feature call FUNCTION, as well as Powerbuilder.

FUNCTION is a collection of scripts or statment which it can be re-used. Normally, FUNCTION has a return value.

In Powerbuilder, there are 2 types of FUNCTION: Function and Window Function. The different is FUNCTION can be use anywhere in object that has capabilities to call function, but Window Function just can called in the window itself.

In this article, I will show you the steps how to declare the function in Powerbuilder. I'm using Powerbuilder version 6.5 and I'm sure it will be the same for all versions above

In the main toolbar, click Function painter.


Click New to create a new Function


Type the name of the function, in the example: f_yearafter
Also specify the type of return variable, in this example: date
Function can has many parameters. Parameters can used to passing some value(s) into function, so later can be used to process or calculate something in the script of function. Beside the name of parameters, you must specify the type of parameters, and the Pass By. There are 3 types of Pass by: value, reference, and readonly. Use reference if you want to change the value parameter then inside the function script.
Click OK to create.


Now you can type the script inside the.
In this example, we create a function call f_yearafter. The function will return a date type value, which it is the date result after some year added.

Once the function created, you can't change or rename the function name, but you can still change the return value, the parameter, etc. Please pay the attention, changing all of that value, will affect into the script inside the function. You can click the function painter icon in the toolbar, to edit the function



To call the function, just add the script like this:

Date dReturnFunction

//add 2 years for the date
dReturnFunction = f_yearafter("01/01/2008",2) // will return "01/01/2010"

Unlock SA login in Microsoft SQL Server

If you or your team members who has access to your Microsoft SQL Server database with SA login, did type the wrong password three times, normally the SA login will be locked. It should be an error :

Login failed for 'sa' because the account is currently locked out. The system administrator can unlock it.

To solve this problem, you need an authority to access the database server directly. Login with the administrator login name, then open Microsoft SQL Server Management Studio. Choose Windows Authentication mode, then click Connect.



Now, in Query windows type this statement then execute

ALTER LOGIN sa WITH PASSWORD = 'sa_password' UNLOCK


There's an option to avoid the sa login to be locked forever, just go to Security, Logins, sa, Properties, then uncheck Enforce password policy option.

Powerbuilder Pipeline

Another feature in Powerbuilder programming is Pipeline.
According to manual help of Powerbuilder, a Pipeline system object is used to manage a data pipeline during execution.

You use a Pipeline object by defining a standard class user object inherited from the built-in Pipeline object in the User Object painter. You can then access the Pipeline events by writing scripts that contain code for the events.

Now I will show you how to execute pipeline by writing the script.

The scenario of this case is you want to pipeline a table from one database to another database. So, first you need at least 2 transaction objects, which mean we must declare first in the top of the script. Since we have a default database connection SQLCA, we only have declare another new transaction object called SQLCAtarget, which represent for the target database connection. Remember, in this case, SQLCA will be the source of database connection

transaction SQLCAtarget // declare this variable as INSTANT variable

SQLCA.DBMS = 'your source dbms name'
SQLCA.Database = 'your source database name'
SQLCA.LogId = 'your source database login id'
SQLCA.LogPass = 'your source database password'
SQLCA.ServerName = 'your source database server'
CONNECT USING SQLCA;

SQLCAtarget = CREATE transaction
SQLCAtarget.DBMS = 'your target dbms name'
SQLCAtarget.Database = 'your target database login id'
SQLCAtarget.LogPass = 'your target database password'
SQLCAtarget.ServerName = 'your target database server'
SQLCAtarget.LogId = 'your target database login id'
CONNECT USING SQLCAtarget;

Next step, you need to build pipeline object by clicking Pipeline painter in main toolbar. Remember, use MAIN TOOLBAR, if you want to pipeline the data to ANOTHER DATABASE.
Setup your source database and the target database profile, chooce the table(s), column(s) and criteria(s), then save as pl_mypipeline.



Choose source and target of Pipeline

Set the table, column and criteria of your pipeline


save your pipeline


Create a window, then put 1 datawindow object and 1 button object. You don't need to put dataobject for the datawindow, just keep it blank. And put the script below at clicked event in button object.

integer iReturn
pipeline myPipeline
myPipeline = CREATE pipeline

myPipeline.DataObject = "pl_mypipeline"
iReturn = myPipeline.Start(SQLCA, SQLCAtarget, dw_1)

// always disconnect your database connection
DISCONNECT USING SQLCA;
DISCONNECT USING SQLCAtarget;

iReturn should be has 0 (zero) value if the pipeline run smoothly.

Modify Compute Field Expression in Powerbuilder

Compute Field is an object in Powerbuilder programming, which can be inserted in datawindow. One of mandatory property of Compute Field is Expression.

Expression is set of statement or syntax which represent what you want to show at this compute field. Can be static text, calculation, or the other things.

When you create a datawindow and insert a compute field object, you can set the expression visually. But some times, you want to change the expression statement dynamically, which mean the expression will change depending of condition. Let say, if one of condition is fulfilled, you want to show: OK in the compute field, otherwise is NO.

Let say, in a Datawindow named dw_1, we create 1 compute object named co_1. The default expression is if(kd_kategori=2,'OK','NO'). It's mean if kd_kategori's value is 2, then we want to show text: OK, otherwise is: NO.




But, in some condition you want to change the default expression into if(kd_kategori=200,'OK','NO'), let say if someone in STAFF level is accessing the application.



Then you must create a script like below:

IF userlevel='STAFF' THEN
   dw_1.object.co_1.expression = "if(kd_kategori=200,'OK','NO')"
ELSE
   dw_1.object.co_1.expression = "if(kd_kategori=2,'OK','NO')"
END IF

Also for those of you who are not comfortable using its touch pad, and often use the mouse, provided also that the key could direct to turn off the touch pad. Not forget to mention, thinness of this notebook is only about 19 mm and the weight started to 1.39 kg, makes you comfortable when you travel.

Rumor: Microsoft will buy Adobe

Adobe Systems Inc. stock price on Thursday (10/07/2010) New York time listed on the Nasdaq stock exchange, had jumped 17 percent to 30 dollars per share before closing at 28.69 dollars per share. Speculation that Microsoft may acquire Adobe's stock price surge triggers the software maker (software) this.

Earlier, The New York Times reported that privately, Microsoft CEO Steve Ballmer has been met with Adobe CEO Narayen Chantanu at Adobe offices in San Francisco recently.

Reportedly, the two talk about the dominance of Apple Inc. in the mobile phone industry and various options to deal with it. According to several employees and consultants involved in the discussion, one of the options they are talking about is the possibility of Microsoft acquiring Adobe.

If it does occur, by referring to Adobe's stock price in the market today, the acquisition price could reach about 15 billion U.S. dollars. This action also will be one of Microsoft's most aggressive step to master the Internet and mobile media markets platform.

With the acquisition of Adobe, Microsoft will master the Flash Player software that is very popular. Now, software has become one of the software required a website to display video and pictures.

Analysts on Wall Street rate, the news of this acquisition makes perfect sense. Because, in this way, Microsoft can integrate graphics and video capabilities in software application Adobe mobile phone or tablet computer product. In this way, the possibility of Microsoft has the opportunity to be able to offset the dominance of Apple's iPhone and iPad fib.

Not too surprising as well if Adobe accept Microsoft's proposal. Because, during Apple CEO Steve Jobs is always criticizing the quality of Flash Player. In fact, he did not recommend that software developers use Flash on the iPhone and iPad.

"Very possibly. It could be a case of so-called enemy of my enemy is my friend. Microsoft and Adobe have a common enemy," said Toan Tran, Morningstar analyst, told Reuters.

However, until now, the good management of both Microsoft and Adobe is not willing to comment on this news.

Notes only, in fact, Microsoft already has a media player on a web platform called Silverlight that compete directly with Flash. However, this product is not too successful with users.

Toshiba Libretto W100 Short Review

In order to celebrate the 25th birthday of their notebook products, Toshiba launched a special product called Toshiba Libretto W100.  Libretto, is one of the classes in Toshiba notebook, which is devoted to small-sized notebook.

Uniquely, the Libretto W100 has 2 screens at once, and has no physical keyboard, such as notebooks in general. When first opened, we will be faced with 2 screens, top and bottom, each measuring 7" wide, with a resolution of 1024x600. The screen can be opened 180 degrees. By default, the screen is "integrated" into a main screen. By pressing the button" keyboard "on the left below, which are made in a dedicated, then at the bottom of the screen will display a virtual keyboard.



The 2 screens are powered by the touch screen technology, so you no longer need any additional equipment such as mouse. But if necessary, has prepared an additional touchpad to move the cursor, again in virtual mode.

I had the opportunity to use this W100 Libretto for 30 minutes. The first impression was, his form was so tiny, a little bit heavy. When I tried the first time it features touch screen, my large-sized fingers facing difficulties to operate the touchscreen commands. Touchscreen technology brings motion gesture, so that like the Apple iPad, you can touch and slide your fingers to enlarge or shrink an image, or to rotate the image.



When tried rotated clockwise, the Toshiba Libretto W100 screen immediately change its position in line with positions such as reading books, in other words the motion sensors are buried in this product.

One disadvantage I found is its internal speakers, a sound which is very soft. To overcome this problem have been provided plug 3.5 "for the earphones



Broadly speaking, the Toshiba Libretto W100, in which embedded possessor U5400 (which is claimed to save energy), OS Microsoft Windows 7 Home Premium, and 62 Gigabyte Solid State Drive, can be a friend in your journey or when you're relaxed, mainly because of its so tiny portable, and relatively long battery endurance because Toshiba Battery 8 Cell buried in it.

How to connect to 2 databases in Powerbuilder

How to connect to more than 1 database in Powerbuilder

Some times, you need to connect to more than 1 database in your application. In Powerbuilder, there's 1 object for database connection that you can create programmatically. The object call: TRANSACTION.

In this example, I will explain how to connect to 2 databases, which mean 1 is with default database connection object (named SQLCA), and the other is the object that we create mannualy.

I'm using Microsoft SQL Server 2000 as a database engine.

First of all, we need to create a transaction object. It's depending on what the purpose of the transaction. You can declare with Instance, Global or even Local variable for this object.

Let's say we create Instant Variable, called: SQLCAID

transaction SQLCAID;


On Open Event, we must create first the transaction object, then setup the properties of the object.

Note: You can try first on the Database painter, to get the right property values, and to make sure that you can connect to the database. Then copy and paste the script.

SQLCAID = CREATE transaction;
SQLCAID.DBMS = "MSS Microsoft SQL Server"
SQLCAID.Database = "database1"
SQLCAID.LogPass = "password"
SQLCAID.ServerName = "localhost"
SQLCAID.LogId = "sa"
SQLCAID.AutoCommit = False
SQLCAID.DBParm = ""


// Try to connect the database
// REMEMBER, you must add USING SQLCAID statement at the end of your SQL Statement, every times you want to execute your database that related with SQLCAID transaction

CONNECT USING SQLCAID;

// Trap the error if the object can't connect to database

IF SQLCAID.SQLCode <> 0 THEN
    MessageBox("Connection Error to "+SQLCAID.Database, &
        "Unable to connect to database. Make sure you type the correct password." + &
        "~r~nTry Again. If the problem persists, contact IT Officer" + &
        "~r~nSQLDBCode = " + String(SQLCAID.SQLDBCode) + &
        "~r~nSQLErrText = " + SQLCAID.SQLErrText)
   HALT
END IF



At the other side, you still must declare the DEFAULT SQLCA transaction object.

SQLCA.DBMS = "MSS Microsoft SQL Server"
SQLCA.Database = "databasedefault"
SQLCA.LogPass = "password"
SQLCA.ServerName = "localhost"
SQLCA.LogId = "sa"
SQLCA.AutoCommit = False
SQLCA.DBParm = ""


// Just for make sure that you connect with SQLCA transaction

CONNECT USING SQLCA;


// Trap the error if the object can't connect to database
IF SQLCA.SQLCode <> 0 THEN
    MessageBox("Connection Error to "+SQLCA.Database, &
        "Unable to connect to database. Make sure you type the correct password." + &
        "~r~nTry Again. If the problem persists, contact IT Officer" + &
        "~r~nSQLDBCode = " + String(SQLCA.SQLDBCode) + &
        "~r~nSQLErrText = " + SQLCA.SQLErrText)
   HALT
END IF


Now you already connected with 2 databases.

Remember, always put USING SQLCA or USING SQLCAID statement at the end of your SQL Statement to make sure that the SQL Statement will execute into the database that you purpose

Example:

string sProductID, sProductName

// will retrieve the product_id and product_name column from SQLCAID transaction
SELECT product_id, product_name INTO :sProductID, :sProductName FROM product_master USING SQLCAID;

// will retrieve the product_id and product_name column from SQLCA (Default) transaction
SELECT product_id, product_name INTO :sProductID, :sProductName FROM product_master USING SQLCA;
