Creating the Application

Follow the steps below to create the application:

Start a new EXE project. Select Microsoft Word 9.0 object library from the references dialog box (Project|References menu). Remember, you should have Word instance on your system. Add a new module to the project. In the module's general declarations section, add the following code:

Public objApp as New Word.application
Public objDoc as Object

Open the project's form and add four buttons to the form.
Buttons are:

1. Launch
   
2. Save
   
3. Close
   
4. Exit

Now double click the "Launch" button and add the following code:

Private sub cmdLaunch_click()

If Not(objdoc is nothing) then
    MsgBox "Application already running"
    Exit Sub
End if

'show the app
objapp.visible=true

'Add a document to the application

Set objdoc = objapp.Documents.Add()

'Write some text in the document

objdoc.content = "This is my first OLE application"

End Sub

Let's discuss the code. We check if the application is already running, if it's not then we display the application. We add a new document to the open word application and add some text to the application.
