effective VBA

For Append As：

Open "1.txt" For Append As #1
Open "1.txt"就是打开名为1.txt的文件
For Append就是追加的意思，也就是在原有文件内容的后面增加新的内容
As #1是把打开的文件标识为一个句柄#1，用于后面的代码对这个文件进读写行操作，

比如print #1, "1234"

打开word文档：

Sub test()
    Dim DocApp As Object
    Set DocApp = CreateObject("Word.Application")
    DocApp.Visible = True
    DocApp.Documents.Open Filename:="D:\abc\123.doc"
End Sub

遍历目标文件下所有指定文件（包括子文件夹）：

Dim MyName, Dic, Did, i, T, F, TT, MyFileName
    T = Time
    Set Dic = CreateObject("Scripting.Dictionary")
    Set Did = CreateObject("Scripting.Dictionary")
    Dic.Add ("C:\Users\AA\BB\CC\"), ""
    i = 0
    Do While i < Dic.count
        Ke = Dic.keys
        MyName = Dir(Ke(i), vbDirectory)
        Do While MyName <> ""
            If MyName <> "." And MyName <> ".." Then
                If (GetAttr(Ke(i) & MyName) And vbDirectory) = vbDirectory Then
                    Dic.Add (Ke(i) & MyName & "\"), ""
                End If
            End If
            MyName = Dir
        Loop
        i = i + 1
    Loop
    For Each Ke In Dic.keys
        MyFileName = Dir(Ke & "*.odt")
        Do While MyFileName <> ""
            Did.Add (Ke & MyFileName), ""
            MyFileName = Dir
        Loop
    Next
    For Each Sh In ThisWorkbook.Worksheets
        If Sh.Name = "XXX" Then
            Sheets("XXX").Cells.Delete
            F = True
            Exit For
        Else
            F = False
        End If
    Next
    If Not F Then
        Sheets.Add.Name = "XXX"
    End If
    Sheets("XXX").[a1].Resize(Did.count, 1) = WorksheetFunction.Transpose(Did.keys)

通过excel vba 操作word页眉：

Sub replace_odt(replaceParam As String, odtPath As Variant)
    'replace xxx.doc/odt with data collected from input_format_update.xlsx
    Dim Wdapp, Wd
    Application.ScreenUpdating = False

    Set Wdapp = CreateObject("word.application")

    Set Wd = Wdapp.Documents.Open(odtPath)

    Wdapp.Visible = False
  
    Wdapp.Selection.Find.ClearFormatting
        Wdapp.Selection.Find.replacement.ClearFormatting
        With Wdapp.Selection.Find
                .Text = replaceParam 'need to be replaced
                .replacement.Text = "[NAME]" ' want to replace with
                .Forward = True
                .Wrap = 1
                .Format = False
                .MatchCase = False
                .MatchWholeWord = False
                .MatchByte = True
                .MatchWildcards = False
                .MatchSoundsLike = False
                .MatchAllWordForms = False
        End With
        Wdapp.Selection.Find.Execute replace:=2
   
    Wd.SaveAs odtPath
    Wd.Close
    Wdapp.Quit

   
    Set Wd = Nothing
    Set Wdapp = Nothing
    Application.ScreenUpdating = True
End Sub

 

上面操作word的时候相当于通过以下代码创造一个word vba 环境

(word vba 代码前面加 wdapp.)

Set Wdapp = CreateObject("word.application")

    Set Wd = Wdapp.Documents.Open(odtPath)

    Wdapp.Visible = False
  
    Wdapp.Selection.Find.ClearFormatting
        Wdapp.Selection.Find.replacement.ClearFormatting
        With Wdapp.Selection.Find

 

on error:

 

On Error Resume Next：

写在最前面，如果sub中出现异常/错误，程序会继续执行，不会停

On Error GoTo ErrorFlag：

与下面代码一起食用，在喜欢的地方放置，如果出现异常/错误，就会触发XXX

ErrorFlag:

　　XXX（定义好的function）

Exit Sub

 

 

清空sheet：

Worksheets("XXX").UsedRange.ClearContents

 

在某处生成文件：

Sub test()

　　　　　　　　　　　　　　任意格式文件都可以
    Open "C:\Users\-----------------\a.docx" For Output As #1
Print #1, "test"

Close #1

End Sub
