Standard And Activex .Exe Projects:
2. Standard and ActiveX Applications
2.1 What is a standard exe application?
A standard exe application is one that is created using
Standard EXE project. It is the most widely used Project
type using VB6. Standard EXE application is normally the
most widely used among the available Project types in Visual
Basic. Stand-alone programs have an .EXE file extension.
2.2 Standard EXE areas of use:
A standard EXE application is normally used when you
want to develop a stand-alone application. Examples include
calculators, text editors, and other similar applications.
2.3 What is an ActiveX EXE application?
An ActiveX EXE application is one that is created using
ActiveX EXE project. ActiveX EXE are widely used in conjunction
with standard EXE applications. There are three types of
widely used of ActiveX projects. These are:
a. ActiveX EXE
b. ActiveX DLL
c. ActiveX Control
ActiveX EXE: Unlike a stand-alone EXE file, an ActiveX
EXE file is designed to work as an OLE server, which is
nothing more than a program designed to share information
with another program. It has an .EXE file extension.
ActiveX DLL: ActiveX DLL files are not meant to be
used by themselves. Instead, these types of files contain
subprograms designed to function as building blocks when
creating a stand-alone program. It has a .DLL file extension.
ActiveX Control: Unlike an ActiveX DLL or ActiveX
EXE file, an ActiveX Control file usually provides both
subprograms and a user interface that you can reuse in other
programs. It has an .OCX file extension.
2.4 ActiveX EXE/DLL Usage
- The ActiveX EXE/DLL is normally used when you need
to build a component that is separate from the main
program. The concept is based on COM model.
- ActiveX DLL/EXE allows multiple applications to
share the same code. This allows for scalability of
programs, and saves time because you only need to write
the code once.
- ActiveX DLLs and ActiveX EXEs are almost same in
the ways they are built and used. In either case, you
build one or more classes that applications can use
to do something.
- One of the main differences between ActiveX EXE
and an ActiveX DLL's is that the code is executed within
the main program's address space for ActiveX DLL. This
is because the code lies inside the program's address
space, calling methods and execution of code is very
