Question

If e.KeyCode = Keys.Enter Then
Dim q As Integer = InputBox("请输入搜索页码的次数")
If q > 0 Then
Static Dim p(q) As String
Dim j As Integer
For j = 0 To q - 1
p(j) = InputBox("请输入关键字")

            Next
            Dim temp

                For j = 0 To q - 1
                    If p(j) > p(j + 1) Then
                        temp = p(j)
                        p(j) = p(j + 1)
                        p(j + 1) = temp

                    End If

                    WDAPP.Documents.Close(Word.WdSaveOptions.wdDoNotSaveChanges)
                    WDAPP1.Selection.EndKey()

                    WDAPP1.Selection.ParagraphFormat.TabStops.Add(Position:=WDAPP1.CentimetersToPoints(20), Alignment:=2, Leader:=2)

                    WDAPP1.Selection.TypeText(Text:=vbTab)

                    WDAPP1.Selection.TypeText(Text:=i)

                    WDAPP1.Selection.TypeText(Text:=vbCrLf)
                    If WDAPP1.ActiveDocument.Saved = False Then


                        WDAPP1.ActiveDocument.Save()
                    End If
                    WDAPP.Quit()

                    WDAPP1 = Nothing

                End With
            Next

        End If


    End If
        报错这句 WDAPP1.Selection.TypeText(text:=p(j))
        “System.Runtime.InteropServices.COMException”类型的未经处理的异常在 Microsoft.VisualBasic.dll 中发生 

其他信息: 类型不匹配。 (异常来自 HRESULT:0x80020005 (DISP_E_TYPEMISMATCH))

我查资料说是这个错误是因为要调用com里的东西。但始终不知道应该加什么
