Once ActiveX controls install and run on the machine it doesn t need to install and run again, saving the download time after first use. Java has been developed to work on any kind of machine and operating system and do not need of any kind of plug-in. Some Examples of making ActiveX controls Softwares Required: Microsoft Front page, Visual Basic 6.0 and windows media player 6.4 How to build? ActiveX controls that you build in Visual Basic (or any language, for that matter) are not only useful in development tools but also in end-user applications. For example, you can embed an ActiveX control created in Visual Basic in an HTML document that will be viewed in a Web browser such as Microsoft Internet Explorer. The application in which an ActiveX control is displayed is referred to as the control s container. Visual Basic is the ActiveX control container used for most of the examples however, keep in mind that your control might be activated in containers other than Visual Basic.

In the components window check on window media player and Microsoft common dialogue 6.0 then click ok. You will find window media player and common dialogue button on the left toolbar. Step 3: Double click on the window media player and common dialogue button to insert them in the dotted area. Drag and adjust it as you like.

4 Step 4: By double clicking in dotted area the code window will appear, write the following code Dim str As String Private Sub Command1_Click() CommonDialog1.ShowOpen str = CommonDialog1.FileName If str <> "" Then WindowsMediaPlayer1.FileName = str WindowsMediaPlayer1.Play End If End Sub Save it in the desired folder. You can run the program by clicking on the play button on the top tool bar Step 5: Go to files and click on make project.ocx

5 Now the ActiveX control has been created How to run ActiveX control over the internet: Step 1: Create a.cab( cabinet) file Click on start menu Go to programs Go to Microsoft Visual Studio 6.0 tools

6 Click on Package and Deployment Wizard A new dialogue box will open. Browse where your project is and then click on the package icon.

7 On Package Type dialogue box click on the internet package option. Follow the directions. Click yes when asked to create the package folder. In the File Source dialogue box check on Include in this cab and click next.
