I cover object models in several posts within Power Spreadsheets. Some of the object models I've written about are the following:.
As I explain in any of those posts, is important to have a good understanding of the object model of the application s you're working with. The main reason for this is that, whenever you're working with VBA, you're basically manipulating the objects of that application.
Therefore, in this section, I provide a short introduction to this particular model. As a general rule, you can picture a VBA object model as being a hierarchy. This hierarchy contains all of the objects you can use. Object model hierarchies have an object at the top. That object contains other objects. Those objects may, in turn, contain other objects. This process goes on until. Therefore, any object within the object model hierarchy has the potential of containing other objects.
In any case, you eventually reach a point where a particular object doesn't hold any other objects. This basic idea is pretty much the same regardless of which particular VBA object model you're looking at. In other words, even though the exact components of the Word object model differ from those of the Excel object model, their structure follows the general rule I explain above.
The object at the top of a VBA object model is usually known as Application. The Application object represents the relevant application. More precisely:. Since Word's Application object contains other objects, you can think of it as the root from which you access all the other objects of Word's object model. You generally obtain access to Word's top-level objects by appropriately using the properties of the Application object. For purposes of this VBA tutorial, 2 particular properties and their associated objects are very relevant:.
The main purpose of the Application. Documents property is to return a Documents collection. The Documents object returned by the Application.
Documents property is a collection representing all the Document objects currently open. Each of those Document objects represents an individual document. For example, the following image shows 5 open Word documents. In this case, the Documents collection represents all of these documents Document1 through Document5. Each of the individual documents Document1, Document2, Document3, Document4 and Document5 is represented by an individual Document object. ActiveDocument property is to return the Document object that represents the current active Word document.
The basic syntax of Application. ActiveDocument follows that of the Application. Documents property above:. Automation is probably the most commonly used and the preferred tool for purposes for purposes of controlling one Windows application from another. When using Automation for purposes of manipulating one application from another one, you refer to the relevant applications as follows:.
In this context, a particularly important advantage of Automation is that it allows you to programmatically access the Component Object Model COM objects offered by the Server Application. Automation lets the client application harness the built-in capabilities of the server application. In the case we're looking at, you use Excel to harness the built-in capabilities of Word.
The purpose of doing this, in this case, is to convert the contents of a PDF file to Excel. For purposes of using Automation, the main thing you need to is create a connection between the relevant applications. In this particular case, those applications are Word and Excel. In the sections below, I provide samples of VBA code that use both early and late binding. In the section containing the code sample that uses early binding, I also show how you can create a reference to Word's object library.
The basic steps of this process open file, copy and paste are roughly the same as the steps followed by the previous macro examples 1 using Adobe Reader and 2 with Able2Extract. Therefore, you may notice that some lines of code are substantially the same as those used by the previous samples. I explain each of the lines of code below. When appropriate, I refer to the equivalent lines of code in previous sections. However, since this particular macro uses early binding, you must start by setting up a reference to the relevant object libraries.
Let's start by taking a look at this:. In order to create these references, go to the Visual Basic Editor and follow these 4 easy steps :. Once you've set the object reference, you can access the Word object model and use the objects, methods and properties it contains. The purpose of the myWorksheet object variable is to represent the Excel worksheet where the data within the PDF file is pasted.
The main purpose of this line of code is to create a variable representing the Word application in order to expose the Word object model. The purpose of this line of code is similar to that of the previous line 2. More precisely, this line 3 creates the variable that provides access to the native Windows shell. I explain why myWshShell is required when explaining line 13 below. Its purpose is to declare a variable that holds the path to the PDF file you want to convert to Excel.
It uses the Set statement to assign a particular worksheet Word Early Binding of the active workbook to the myWorksheet object variable. Both of these lines of code use the Set statement for purposes of assigning a new New instance of the relevant object to the applicable object variable.
This line of code uses Word's Application. Version property wordApp. This property returns the version number of the relevant Word version. That version number returned by the Version property is assigned to the wordVersion variable. The expression on the right side of the assignment operator is created by concatenating the following 3 items:.
In order to understand why this statement is necessary, let's take a look at what happens when you manually open a PDF file using Word :. Additionally, you have the option of specifying that the message shouldn't be displayed again.
To do this, you just need to check the relevant box that appears on the left side of the dialog box. Clicking the OK button manually is quite easy. At first glance, this is something that would also be easy to handle using VBA. The key that corresponds to the value written to the registry doesn't initially exist. In order to proceed with the PDF to Word conversion, you must solve this.
The statement uses the RegWrite method of the WshShell object. You can use the RegWrite method for 3 main purposes :. The practical effect of this line of code 13 is that the warning in the dialog box that I explain above regarding the PDF to Word conversion is turned off. Therefore, Visual Basic for Applications is able to proceed with…. Lines 14 to 16 are a single statement. The statement calls the Documents. Open method. This method allows you to:. Notice that the statement we're analyzing only makes reference to 2 of the parameters of Documents.
Open :. As a consequence of the above, the practical effect of lines 14 to 16 is that Word opens the PDF file you want to convert to Excel. The only difference between lines 15 and 17 is the value assigned to the anyValue parameter of the RegWrite method. In practice, line 17 reverses what line 15 does. In other words, it turns the warning regarding the PDF to Word conversion back on. Other than the above, the general aspects within the explanation I provide in line 15 above are applicable.
Uses Word's Range. Copy method for purposes of copying the content of the file you want to convert. Within this line 18, this Range object is that returned by the Document. Content property. When you use Document. The Document object to which the Content property makes reference to is the active word document returned by Word's Application. ActiveDocument property. The practical effect of With… End With is that the series of statements within the block are executed on the same object.
In the case of the sample macro we're looking at:. The whole With… End With block composed by lines 19 to 22 of this sample macro has substantially the same effect as lines 17 to 20 of the previous macro examples.
This line of code is the same as line 18 of prior code examples. It uses the Range. Select method to select cell B4 of myWorksheet.
This line sets the location where the data from the PDF file you're converting is pasted. This statement is needed because it's required by the Worksheet.
PasteSpecial method used by…. More precisely, it uses the Worksheet. PasteSpecial method for purposes of pasting the contents of within the Clipboard on the selected range see line 20 above using a particular format.
