Why I use Delphi?

Why I use Delphi?

As I am a Delphi developer from last 5 years. I worked on several Delphi projects in several companies in India. In my last company we recruited a fresher to work with our team in Delphi. His first question was What is Delphi and Why I use it?. Even his friends suggested to leave Delphi as there is no future opportunity. And one day he said he wants to leave Delphi. I asked him what is the reason you want to leave. He answered because its outdated language. I got shocked if Delphi is outdated then what about C / C++. But C / C++ are still most power full language. And Delphi uses Object Pascal that is object oriented version of Pascal language which support all the OOPS behavior and new features. And C, Pascal are most powerful languages still today. So I explained him some reason why I use and love Delphi.

So following are some reasons why we use Delphi...

 Speed 
Delphi is not an interpreted language. It compiles Delphi code and generates machine code which executed directly by CPU at runtime. This makes it exceptionally fast. Delphi's string handling is particularly fast, which is important when developing a string-heavy application. As AnsiString was faster than the Microsoft compatible WideString. 

 No Runtime
Delphi application don't required any runtime support to run properly. A Delphi application generated .Exe file that is all in one. We just need to deploy the Exe on clients system. But in case of Java / .Net we need runtime libraries. Today these libraries are included in Windows OS like xp, 7 and later. But still if you don't have correct version installed then you have to download. But in case of Delphi this is not required. So application deployment is very easy.

 Start-Up Time 
Related to the above, well-designed Delphi applications start quickly because they don't have to wait for any runtime to load (assuming it's not already loaded).  To me, this is a critical benefit. Application that take a long time to load have a low perceived performance regardless of how fast they are once they're loaded.

 Universality
Delphi can do almost everything like all other modern languages. There is no need to use anything external. Your program is standalone and do not depends on anything. If you need it, it is easy to call external software or be called by external software. Delphi supports almost everything, from low level API to high level database. You can write business application as well as process control, communication or multimedia applications. You can build full blown GUI application 2D or 3D, or build web applications using soap, rest and more.

 Backward Compatibility
Source code compatibility is definitely an issue. Borland/CodeGear have proven to provide backwards compatibility for many, many years, creating solid products. But in case of .Net there is always incompatibility issues found.

 Some new features in new Delphi versions
I have just mentioned some new features. Still there is more features you will find.

  •    Can create cross platform application Windows,MAC OSx with FireMonkey
  •    Can create multi-device applications
  •    Can create 32bit, 64bit application
  •    Cross platform data provider components – FireDAC
  •    Can create rich HD, 3D GUI applications with theme.
  •    Can create native mobile apps for IOS, Android 
  •    Provides inbuilt cloud service support

But at finally every body thinks about the Jobs in software development. Everybody like to work on a language on which they can get job easily and should provide job security. According to me, as per my experience a Delphi developer can get job easily in today market in India. No doubt there is less software company working on Delphi and there is less Delphi job in comparison to .net, java. But if you compare total number of Delphi developer to total Delphi developer job then you can find there is more job in Delphi in comparison to same situation in .net, java.

Even if you google then you can find some great application have built with using Delphi. Example.- Skype. Even you can find more applications on following link.

So Delphi was alive, Delphi is alive and Delphi will be alive like evergreen. And if still you think then go to http://www.isdelphidead.com

ShellExecute in Delphi

ShellExecute in Delphi – Launch external applications. ShellExecute is Delphi Windows API function that is mostly used for launch external applications from our Delphi application. This function is linked to the ShellExecute Windows  API function. The function returns an integer that corresponds to an error code which is very useful when we need to show some status  if the function worked  or not . By using ShellExecute we can also do following operations.... Can print documents from within my program, without explicitly starting the application  that created the document, such as: print a Word-document without starting Word. Can open browser with a local HTML page Can surf to a site i.e. open an external URL link from a Delphi application Can send mails thorugh outlook Syntax of Windows API function HINSTANCE ShellExecute(   _In_opt_        HWND hwnd,   _In_opt_        LPCTSTR lpOperation,   _In_              LPCTSTR lpFile,   _In_opt_        LPC

MS Excel Automation in Delphi

In this blog I will describe how to read and write data from and to an Excel file. Sometime in our application we use Excel for reporting purpose, for data import / export purpose and for other works. So here I will explain how to access an Excel file and use for data read / write. For this Excel 2003 or later should have installed in our system. First use Excel2000 unit to uses clause. This unit comes with Delphi installation it self. You can get the unit in installed path C:\Program Files (x86)\Embarcadero\RAD Studio\10.0\OCX\Servers Uses    Excel2000; Before proceed I would mention an important word  LCID which is required at most places. So what it LCID? LCID = In Microsoft Excel, the LCID indicates the currency symbol to be used when this is an xlListDataTypeCurrency type.  Returns 0 (which is the Language Neutral LCID) when no locale is set for the data type of the column. We can get LCID in Delphi by using  GetUserDefaultLCID  function.. privat

Drawing Shapes in Delphi

Believe me, drawing shapes in Delphi is so easy. To develop a software like CAD, Paint, CorelDraw Delphi provides large number of classes and members that supports to draw shapes on a form or on a graphic control. In Delphi, we draw shapes on canvas of a form or graphic controls. Canvas is an area of form where we can draw shapes, lines and can fill colors on shapes. In Delphi, every form or graphic controls have Canvas property which provides TCanvas object that can be used to draw shapes. TPen object is used to draw lines and we can set size, color of lines. TBrush object is used to set color and style to fill the shapes. Most frequently used classes for drawing shapes are TCanvas , TBitmap, TGraphics, TPen, TBrush TCanvas Use TCanvas as a drawing surface for objects that draw an image of themselves TBitmap   Bitmap is a powerful graphics object used to create, manipulate (scale, scroll, rotate, and paint), and store images in memory and as files on a disk.  TGraphics TGr
