′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
′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
′返回一个字符串数组
′调用举例:
′Dim arrClass() As String
′arrClass = GetInfoSection(“class”, “d:type.ini”)
Public Function GetInfoSection(strSection As String, strIniFile As String) As String()
Dim strReturn As String * 32767
Dim strTmp As String
Dim nStart As Integer, nEnd As Integer, i As Integer
Dim sArray() As String
Call GetPrivateProfileSection(strSection, strReturn, Len(strReturn), strIniFile)
strTmp = strReturn
i = 1
Do While strTmp <> “”
nStart = nEnd + 1
nEnd = InStr(nStart, strReturn, vbNullchar)
strTmp = mid$(strReturn, nStart, nEnd – nStart)
If Len(strTmp) > 0 Then
ReDim Preserve sArray(1 To i)
sArray(i) = strTmp
i = i + 1
End If
Loop
GetInfoSection = sArray
End Function
′————————(2)————————————
′作用:去掉字符串中的首尾空格、所有无效字符
′测试用例
′Dim strRes As String
′Dim strSour As String
′
′strSour = ” ” & vbNullchar & vbNullchar & ” ab cd” & vbNullchar
′strRes = zqTrim(strSour)
′MsgBox ” 长度=” & Len(strSour) & “值=111” & strRes & “222”
Public Function zqTrim(ByVal strSour As String) As String
Dim strTmp As String
Dim nLen As Integer
Dim i As Integer, j As Integer
Dim strNow As String, strValid() As String, strNew As String
′strNow 当前字符
′strValid 有效字符
′strNew 最后生成的新字符
strTmp = Trim$(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) ′每次读取一个字符
′MsgBox Asc(strNow)
If strNow <> vbNullchar And Asc(strNow) <> 9 Then ′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, “”) ′将所有有效字符连接起来
zqTrim = Trim$(strNew) ′去掉字符串中的首尾空格
End Function
′————————(3)————————————
′检查文件是否存在,存在返回TRUE,否则返回FALSE
Public Function CheckFileExist(strFile As String) As Boolean
If Dir(strFile, vbDirectory) <> “” Then
CheckFileExist = True
Else
CheckFileExist = False
End If
End Function
′————————(4)————————————
′获得指定ini文件中某个节下面某个子键的键值,需要下面的API声明
′Public Declare Function GetPrivateProfileString Lib “kernel32” Alias _
′”GetPrivateProfileStringA” (ByVal lpApplicationName As String, _
′ ByVal lpKeyName As Any, ByVal lpDefault As String, ByVal lpReturnedString _
′As String, ByVal nSize As Long, ByVal lpFileName As String) As Long
′返回一个字符串
′调用举例:
′Dim strRun As String
′strRun = GetiniValue(“Windows”,”Run”, “C:WindowsWin.ini”)
Public Function GetiniValue(ByVal lpKeyName As String, ByVal strName As String, ByVal strIniFile As String) As String
Dim strTmp As String * 255
Call GetPrivateProfileString(lpKeyName, strName, “”, _
strTmp, Len(strTmp), strIniFile)
GetiniValue = Left$(strTmp, InStr(strTmp, vbNullchar) – 1)
End Function
′————————(5)————————————
′获得Windows目录 ,需要下面的API声明
′Private Declare Function GetWindowsDirectory Lib “kernel32” Alias “GetWindowsDirectoryA” (ByVal lpBuffer As String, ByVal nSize As Long) As Long
′返回一个字符串,如“C:Windows”、“C:Winnt”
′调用举例:
′Dim strWindir As String
′strWindir = GetWinDir()
Private Function GetWinDir()
Dim windir As String * 100
Call GetWindowsDirectory(windir, 100)
GetWinDir = Left$(windir, InStr(windir, vbNullchar) – 1)
End Function
′————————(6)————————————
′获得Windows系统目录,需要下面的API声明
′Private Declare Function GetSystemDirectory Lib “kernel32” Alias “GetSystemDirectoryA” (ByVal lpBuffer As String, ByVal nSize As Long) As Long
′返回一个字符串,如“C:WindowsSystem”、“C:WinntSystem32”
′调用举例:
′Dim strSysDir As String
′strSysDir = GetSystemDir()
Private Function GetSystemDir()
Dim strSysDir As String * 100
Call GetSystemDirectory(strSysDir, 100)
GetSystemDir = Left$(strSysDir, InStr(strSysDir, vbNullchar) – 1)
