As a Software Developer, usually what is your tool kit for Software development?

depends on type of software you are building, for example web development and deployment can be done by WAMP on windows, WAMP also helps in database construction and maintainance, ECLIPSE is open source and is mostly used for many types of software building eclipse is used for java, android and for other too. WAMP is also open source

Comonly i am using Visual Basic and c++

eclipse, notepadd++, visual

As a Php developer I am using PhpDesigner8 these days that is a lightning fast and powerful PHP IDE and PHP editor boosted with all the features to help to create websites.It has built-in editors for PHP, HTML5-, CSS3- and JavaScript!

I had been using notepad++ and wamp for Lamp environment.

For eror handling firebug is also good.Firebug integrates with Firefox to put a wealth of web development tools at your fingertips while you browse. You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page.

Cheers!

For enterprise they will use for most languages Microsoft Visual Studio and for java eclipse and both of them support most programming language . For your info even java can work on visual studio and there are many plug-in for mostly all languages in eclipse .

University and students they use mostly free version and open source toolkits .

What do you mean by tool kit?

You mean software development kit or work frame or development environment? 

You have to identify what you mean so I can answer you

it depends on the programming language you are using, i.e. the tool kit for Java differs from the toolkit for C sharp or C++. if you want to know one in specific please go ahead.

for java programm language

use JRE and JDK with Netbeans program or Eclipse

it's depends what you want to build, is it website ? webapp , or windsows software ? 

My Common Front End Development Tool is PowerBuilder (any vesion) for Client/Server Applications.

For Web Services and Web Portal I prefer more ASP.NET / VB.NET

AJAX, Java , C++ , JScript, VBScript, HTML all using based on requiremnet and  the Solution Type.

ABAP development is doing for SAP Reports

Crystal Reports in Portals .

All depends on the software needed, the platform to be used, and the security needed for an application. Most common toolkit for web, services and mobile development is Visual Studio in addition to some addin libraries. For mobile development it all depends on the platform.
