类型不匹配循环形状

Question

我在循环幻灯片中的形状的行中出现类型不匹配13错误.我可以看到它oSh是Nothing,但如果我.Count的形状,幻灯片中有很多形状.这有什么意义？

简要代码:

Dim oPP As PowerPoint.Presentation
Dim oS As Slide
Dim oSh As Shape
For Each oS In oPP.Slides
    For Each oSh In oS.Shapes '<-- this line is the error line
        On Error Resume Next
        If oSh.Type = 14 _
                Or oSh.Type = 1 Then
            'do stuff            
        End If
        On Error GoTo 0
    Next oSh
Next oS

Answer 1

Excel有自己的Shape类型(与PowerPoint.Shape类型不同),因此您应该更改

Dim oSh As Shape

到(早期绑定)

Dim oSh As PowerPoint.Shape

或(对于后期绑定)

Dim oSh As Object 

另请注意,如果您要使用带后期绑定的powerpoint(如建议您的函数名称Sub PPLateBinding()),则应将所有类型更改PowerPoint.Something为Object(除非您添加对powerpoint对象模型的引用,但在这种情况下,我看不出任何原因使用后期绑定).
