Microsoft Office Excel 2003 Programming Inside Out If there isn t a current instance of Word, using the GetObject function with no first argument causes a run-time error. The On Error Resume Next line will allow the code to continue and use the value in the wdApp variable to determine if a new instance of the application will be opened. If the Word application is not loaded into memory, the code then uses the GetObject function with a zero-length string as the first argument, which opens a new instance of Word. Once the instance of Word has been identified, the procedure creates a new document. The code also makes the new instance of Word visible, unlike our previous examples, where the work was done behind the scenes without showing the Word window. The copied data is then pasted at the end of the Word document. At the end of the procedure, the object variable wdApp is released, but the Word window is accessible on the screen so that you can view the result. The CreateNewWordDoc procedure demonstrates how to create a new document, but rather than paste contents into the document the procedure enters the creation date of the file. The program window is also closed, and the file is saved as NewWordDoc.doc.

Controlling Excel from Other Office Applications
Now to go full circle, you should know how to reference the Excel Application object from other Office applications. The same concepts apply; you must start by adding the Excel Object Library to the procedure of the host application, if using early binding. Then you must create an Excel object as outlined in Table 21-2.
Excel and Other Office Applications
Table 21-2.
Excel Objects and Their Functions
Class Name
CreateObject( Excel.Application ) CreateObject( Excel.Sheet ) CreateObject( Excel.Chart )
Top-Level Office Object
Application object Workbook object Chart object
The following procedure was created in Word 2003. A reference was included to reference the Excel Object Library. To execute this procedure, you must add the Excel reference, enter the procedure into Word, and then create a new workbook in the root directory of your C: drive named NewExcelWbk.xls.
Sub OpenWriteExcelWbkContents()
Dim xlApp As Excel.Application
Dim xlWbk As Excel.Workbook
Dim tString As String, r As Long
Documents.Add
Set xlApp = CreateObject("Excel.Application )
Set xlWbk = Excel.Workbooks.Open("C:\NewExcelWbk.xls )
r = 1
With xlWbk.Worksheets(1)
While .Cells(r, 1).Formula <> "" tString = Cells(r, 1).Formula With ActiveDocument.Content .InsertAfter "Contents of file: " & xlWbk.Name
.InsertParagraphAfter
.InsertParagraphAfter
.InsertAfter tString
.InsertParagraphAfter
End With r = r + 1 Wend End With xlWbk.Close xlApp.Quit Set xlWbk = Nothing Set xlApp = Nothing End Sub
The previous example created a basic Excel workbook. Now that you can create a basic workbook, you can copy data and a chart into a Word document. One such workbook is shown in Figure 21-5.

Figure 21-5. the chart.
Here s a sample workbook, displaying the basic setup of data used to create
Setup Requirements The workbook requires some basic setup to run the procedure effectively. The procedure references the filename projection.xls; if you choose to use a different filename, modify your code to reflect the filename you ve chosen. You need to define the range names: StartingValue and PctChange. Each month is calculated based on the previous month multiplied by the PctChange value. These values won t be saved in the Excel workbook before it s closed. The information used to create the chart has also been assigned the range name Data. Finally, create an embedded chart to see the full scope of this procedure.
The CreateExcelChart procedure prompts the user for two values and inserts the values into the worksheet. When the new data is entered into the worksheet the chart is automatically updated.
Sub CreateExcelChart() Dim XLSheet As Object Documents.Add StartVal = InputBox("Starting Value )
