Apply Font Formatting to PowerPoint Text Programmatically

问题

I am trying to use VBA to insert some text into a PowerPoint TextRange, I use something like this:

ActiveWindow.Selection.SlideRange.Shapes("rec1").TextFrame.TextRange.Text = "Hi"

However, I can't figure out how to apply bold, italic and underline programmatically (I don't see a .RichText property or something similar).

What I have is some simple HTML text with bold, italic and underlined text I would like to convert over.

How to do this?

回答1:

This is easily accomplished by using the TextRange's Characters, Words, Sentences, Runs and Paragraphs objects and then it's Font object to set Bold, Underline and Italic (amongst other properties). For example:

Sub setTextDetails()
    Dim tr As TextRange
    Set tr = ActiveWindow.Selection.SlideRange.Shapes(1).TextFrame.TextRange
        With tr
            .Text = "Hi There Buddy!"
            .Words(1).Font.Bold = msoTrue
            .Runs(1).Font.Italic = msoTrue
            .Paragraphs(1).Font.Underline = msoTrue
        End With
End Sub

Try looking at MSDN's documentation on the TextRange object. It contains samples of how to access the Font properties of the TextRange object.

EDIT: You can access things like Bold and Italics programmatically in this manner:

TextRange.Font.Bold = msoTrue

EDIT EDIT: There are several methods by which you can select only certain text in a text range. See the following:

Characters Method
Lines Method
Paragraphs Method
Words Method

According to the sames from this link, you can select a portion of the text using one of these methods and set the font programmatically. For example:

Application.ActiveDocument.Pages(1).Shapes(2) _
.TextFrame.TextRange.Words(Start:=2, Length:=3) _
.Font.Bold = True

That example was taken from the Words Method link.

In addition to the above answer, you should try to name the objects you'll be changing, since selecting them in the middle of a presentation could make PowerPoint act oddly. Create a new TextRange object and set it like this.

dim mytextrange As TextRange
Set mytextrange = ActiveDocument.Pages(1).Shapes(2).TextFrame.TextRange
mytextrange.Words...

Here is how you can do it to change the font of a specific text:

Sub changeFont()

Dim oPresentation   As Presentation
Dim oSlide          As Slide
Dim oShape          As Shape
Dim stringSearched  As String    

stringSearched = "something"

'all opened presentations
For Each oPresentation In Presentations
    'all slide in them
    For Each oSlide In oPresentation.Slides
        'all shapes (anything)
        For Each oShape In oSlide.Shapes
            'only those that contain text
            If oShape.HasTextFrame Then
                If InStr(oShape.TextFrame.TextRange.Text, stringSearched) > 0 Then
                    'here you need to define where the text ends and start
                    oShape.TextFrame.TextRange.Characters(InStr(oShape.TextFrame.TextRange.Text, stringSearched), Len(stringSearched)).Font.Underline = msoTrue
                    oShape.TextFrame.TextRange.Characters(InStr(oShape.TextFrame.TextRange.Text, stringSearched), Len(stringSearched)).Font.Italic = msoFalse
                End If
            End If
        Next
    Next
Next
End Sub
