ActiveX .EXE : A Beginner’s Guide

3. Develop an ActiveX EXE file, with an example

Here we develop a simple ActiveX EXE with just one form. The name of the ActiveX component is clsActivexEx. The example is chosen to demonstrate the use of ActiveX EXE in conjunction with Standard EXE. We will develop a Standard EXE later.

The example provided is simple. It works like this: You select either numbers or alphabets in the Main (Standard EXE). The selection (number/alphabet but not both) is passed on to the ActiveX EXE. Now, in the ActiveX EXE, you select specific number (say “2”) or alphabet (say “A”). That specific number or alphabet is again passed back to the Standard EXE. It is similar to, say, the Standard EXE selects either birds or animals. If the Standard EXE chooses birds, then the ActiveX EXE can choose any one of a given set of birds. It doesn’t have the option to choose any animal (because the Standard EXE already chosen birds). The selected bird is passed back to the Standard EXE. The example makes it clear as you read on.

1. Open Visual Basic 6.0 - it should be on your start menu if you have just installed it Programs -> Microsoft Visual Basic 6.0 -> Microsoft Visual Basic 6.0

Open an instance of Visual Basic Choose ActiveX EXE and select Open.

Go to the properties of class and change its name property to clsActivexEx.

Add a new Form by using Add Form menu item in the project menu.

Change the name property of form to frmActivexEx and the caption to “Form From ActiveX Exe”.

Include the following controls on the form:

Object Property Setting
Command button Name Caption cmdSelAndClose
Select and close
Combo Box Name cboNumbers
Combo Box Name cboAlphabets
Label Caption Numbers:
Label Caption Alphabets:

Open the project properties dialog box by going to Project -> ActivexEx Properties.

In the above figure Project type specifies the type of project that is being developed, in this case the project is of type ActiveX Exe, other project types can be seen by clicking on the combo box.

“Project Name” specifies the name of the component type library.

You include the ActiveX reference at a later stage in to the Standard EXE. Note that the “Project Description” is the one that appears in “Add Reference” dialog box when it’s corresponding component is added.

In this case, startup object is set to “None”, as there is no initialization required for this project.

Go to the component tab and check for the following:

“Version Compatibility” by default is of type “Project Compatibility” for all ActiveX Project types.

“Start Mode” is of type “ActiveX Component” by default. Select the “Standalone” option button, only if you intend to start the application as a standalone,

Now, you write the required code. We have added a new Module for placing our code.

Go to Project -> Add Module.

Refer to appendix-A for code to be included in Class Module.

Refer to appendix-B for code to be included in Form.

Refer to appendix-C for code to be included in Standard Module.

Use ctrl-F5 to compile and make sure that there are no compilation errors.

From the file menu select Make Activex_ex.exe to make an exe file of this project (which is called reference executable) as shown below:
