Use Word Content Control Values for chart object in same Word doc - excel

Question

Using MS Word (in my case 2010 version), I have constructed a form with Content Control elements to be filled out by the user. Now I want certain entries (that I already gave titles to) be shown in a chart inside the same Word document (not in a separate Excel document).
This should be an automated process, so that if the user changes one of the Content Control entries, the chart updates itself automatically; I would also be OK if the user had to press a button in order to update the chart (but the user shouldn't have to click around a lot, since I must assume the user to have little skills.)
So I inserted an Excel chart object in my Word form document. I also wrote some VBA code inside this Excel object to read the Content Control values from the Word document as source for the chart. But I think what I really need is the VBA code to be in my Word document itself (for example to be executed upon click on a button by the user), yet I don't know how to address the Excel chart object and the cells within.
My VBA code inside the Excel object is:
Sub ChartDataAcquirer()
Dim wdApp As Object
Dim wdDoc As Object
Dim DocName As String
Dim ccX As String
Dim ccY As String
Dim datapairs As Integer
'''''''''' Variables '''''''''
DocName = "wordform.docm"
ccX = "titleX"
ccY = "titleY"
datapairs = 5
''''''''''''''''''''''''''''''
Set wdApp = GetObject(, "Word.Application")
Set wdDoc = wdApp.Documents(DocName)
Dim i As Integer
For i = 1 To datapairs
With ActiveSheet.Cells(i + 1, 1) ' The first row contains headline, therefore i+1
.Value = wdDoc.SelectContentControlsByTitle(ccX & i).Item(1).Range.Text ' The CC objects containing the x values have titles "titleX1", "titleX2" ..., therefore "ccX & i"
On Error Resume Next
.Value = CSng(wdDoc.SelectContentControlsByTitle(ccX & i).Item(1).Range.Text) ' To transform text into numbers, if user filled the CC object with numbers (which he should do)
End With
With ActiveSheet.Cells(i + 1, 2)
.Value = wdDoc.SelectContentControlsByTitle(ccY & i).Item(1).Range.Text
On Error Resume Next
.Value = CSng(wdDoc.SelectContentControlsByTitle(ccY & i).Item(1).Range.Text)
End With
Next
End Sub
I guess I need a similar code that is placed in and operates from the Word form document itself, but that is where I am stuck...

Answer 1

The following is demo code that shows how to access an embedded Excel chart.
Note that the Name (Shapes([indexValue])) of your chart Shape is probably different than in this code. You'll need to check and change that assignment. Also, your chart may be an InlineShape rather than a Shape, so you may need to adjust that bit, as well.
This code checks whether the Shape is actually a chart. If it is, the Chart object is accessed as well as its data sheet. Via that, it's possible to get the actual workbook, the worksheets, even the Excel application if you should need it.
Sub EditChartData()
Dim doc As Word.Document
Dim shp As Word.Shape
Dim cht As Word.Chart
Dim wb As Excel.Workbook, ws As Excel.Worksheet, xlApp As Excel.Application
Set doc = ActiveDocument
Set shp = doc.Shapes("MyChart")
If shp.HasChart Then
Set cht = shp.Chart
cht.ChartData.Activate
Set wb = cht.ChartData.Workbook
Set xlApp = wb.Application
Set ws = wb.ActiveSheet
Debug.Print ws.Cells(1, 2).Value2
End If
Set ws = Nothing
Set wb = Nothing
Set cht = Nothing
Set xlApp = Nothing
End Sub
