注释：获得指定ini文件中某个节下面的所有键值 TrueZq,,需要下面的API声明
注释：Private Declare Function GetPrivateProfileSection Lib "kernel32" Alias "GetPrivateProfileSectionA" (ByVal lpAppName As String, ByVal lpReturnedString As String, ByVal nSize As Long, ByVal lpFileName As String) As Long
注释：返回一个字符串数组
注释：调用举例：
注释：Dim arrClass() As String
注释：arrClass = GetInfoSection("class", "d:\type.ini")
Public Function GetInfoSection(strSection As String, strIniFile As String) As String()
Dim strReturn As String * 32767

Do While strTmp <> ""
nStart = nEnd + 1

注释：作用：去掉字符串中的首尾空格、所有无效字符
注释：测试用例
注释：Dim strRes As String
注释：Dim strSour As String
注释：
注释：strSour = " " & vbNullChar & vbNullChar & " ab cd" & vbNullChar
注释：strRes = zqTrim(strSour)
注释：MsgBox " 长度=" & Len(strSour) & "值=111" & strRes & "222"
Public Function zqTrim(ByVal strSour As String) As String
Dim strTmp As String
Dim nLen As Integer
Dim i As Integer, j As Integer
Dim strNow As String, strValid() As String, strNew As String
注释：strNow 当前字符
注释：strValid 有效字符
注释：strNew 最后生成的新字符
strTmp = Trim$(strSour)
nLen = Len(strTmp)
If nLen < 1 Then
zqTrim = ""
Exit Function
End If
j = 0
For i = 1 To nLen
strNow = Mid(strTmp, i, 1) 注释：每次读取一个字符
注释：MsgBox Asc(strNow)
If strNow <> vbNullChar And Asc(strNow) <> 9 Then 注释：如果有效，则存入有效数组
ReDim Preserve strValid(j)
strValid(j) = strNow
j = j + 1
End If
Next i
strNew = Join(strValid, "") 注释：将所有有效字符连接起来
zqTrim = Trim$(strNew) 注释：去掉字符串中的首尾空格
End Function

注释：检查文件是否存在,存在返回 TRUE,否则返回FALSE
Public Function CheckFileExist(strFile As String) As Boolean
If Dir(strFile, vbDirectory) <> "" Then

注释： ByVal lpKeyName As Any, ByVal lpDefault As String, ByVal lpReturnedString _
注释： As String, ByVal nSize As Long, ByVal lpFileName As String) As Long
注释：返回一个字符串
注释：调用举例：
注释：Dim strRun As String
注释：strRun = GetiniValue("Windows","Run", "C:\Windows\Win.ini")
Public Function GetiniValue(ByVal lpKeyName As String, ByVal strName As String, ByVal strIniFile As String) As String
Dim strTmp As String * 255
