用VB将目录里所有文件及子目录存储到一个类型数组中后，将基其反映在Treeview控件上

经过3天的苦苦思考，于今日终于完成了将一个目录里所有文件及子目录存储到一个类型数组中后，然后将这个数组信息存储到一个TreeView控件中。下面将我3天来的成绩写给大家，以供交流参考。

1、在Form上添加一个TreeView控件，命名为T；一个ImageList控件，命名为Img1，选择Img1控件，右键单击－＞属性－＞图像－＞插入两个图片（索引为1、2用于显示目录或文件）；添加一个CommandButton按钮，Caption属性为：“遍历文件夹”，命名为BtnShowTree,代码如下：

Private Type Folder
     FolderName As String '文件夹的名字
     FolderLogo As String '文件夹的标志
End Type
Private Type FolderOrFile
        FName As String '名字
        FFather As String '父结点
        FType As Integer '用于判断是文件夹还是文件1代表文件夹，0代表文件
        Flogo As String '自身标志
End Type
Dim FolderFile() As FolderOrFile '定义文件夹及文件存储信息数组
Dim Folder() As Folder '定义文件夹信息
Dim N As Integer '用于目录及文件的个数
Dim nodX As Node  '树形控件中

Dim FolderN As Integer '文件夹个数
Dim FolderN_C As Integer '附文件夹个数

Private Sub Form_Load()

T.LineStyle = tvwTreeLines
T.ImageList = Img1
T.Style = tvwTreelinesPlusMinusPictureText
Set nodX = T.Nodes.Add(, , "文件管理系统", "文件管理系统", 1) '添加一个根，注意这个文件夹的根须命名为“文件管理系统”如果要命为其他名称需改其中部分代码

End Sub

Public Sub SearchFolder(ByVal strpath As String) '该函数主要功能是先给“文件管理系统”目录下所有子目录定一个Key,因为TreeView中所有的结点都不能重名，strpath为路径名
On Error Resume Next
Dim Fso As Object
Dim Fol As Object
Set Fso = CreateObject("Scripting.FileSystemObject")
Set Fol = Fso.GetFolder(strpath)
For Each Fol In Fol.subfolders
    FolderN = FolderN + 1
    ReDim Preserve Folder(FolderN)
    Folder(FolderN).FolderName = SJW(Fol.path, SMID(Fol.path))
    Folder(FolderN).FolderLogo = "Folder" & Trim(Str(FolderN))
    SearchFolder Fol
Next
Set Fso = Nothing
Set Fol = Nothing

以上代码在VB6.0环境下调试通过

执行结果为：
