注釋：獲得指定ini文件中某個節下面的所有鍵值 truezq,,需要下面的api聲明
注釋：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
注釋：返回一個字符串數組
注釋：調用舉例：
注釋：dim arrclass() as string
注釋：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$(strreturn, nstart, nend - nstart)
if len(strtmp) > 0 then
redim preserve sarray(1 to i)
sarray(i) = strtmp
i = i + 1
end if
loop
getinfosection = sarray
end function
注釋：————————（2）————————————
注釋：作用：去掉字符串中的首尾空格、所有無效字符
注釋：測試用例
注釋：dim strres as string
注釋：dim strsour as string
注釋：
注釋：strsour = " " & vbnullchar & vbnullchar & " ab cd" & vbnullchar
注釋：strres = zqtrim(strsour)
注釋：msgbox " 長度=" & len(strsour) & "值=111" & strres & "222"
public function zqtrim(byval strsour as string) as string
dim strtmp as string
dim nlen as integer
dim i as integer, j as integer
dim strnow as string, strvalid() as string, strnew as string
注釋：strnow 當前字符
注釋：strvalid 有效字符
注釋：strnew 最后生成的新字符
strtmp = trim$(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) 注釋：每次讀取一個字符
注釋：msgbox asc(strnow)
if strnow <> vbnullchar and asc(strnow) <> 9 then 注釋：如果有效，則存入有效數組
redim preserve strvalid(j)
strvalid(j) = strnow
j = j + 1
end if
next i
strnew = join(strvalid, "") 注釋：將所有有效字符連接起來
zqtrim = trim$(strnew) 注釋：去掉字符串中的首尾空格
end function
注釋：————————（3）————————————
注釋：檢查文件是否存在,存在返回 true,否則返回false
public function checkfileexist(strfile as string) as boolean
if dir(strfile, vbdirectory) <> "" then
checkfileexist = true
else
checkfileexist = false
end if
end function

注釋： byval lpkeyname as any, byval lpdefault as string, byval lpreturnedstring _
注釋： as string, byval nsize as long, byval lpfilename as string) as long
注釋：返回一個字符串
注釋：調用舉例：
注釋：dim strrun as string
注釋：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

strtmp, len(strtmp), strinifile)
getinivalue = left$(strtmp, instr(strtmp, vbnullchar) - 1)
end function

注釋：獲得windows目錄 ,需要下面的api聲明
注釋：private declare function getwindowsdirectory lib "kernel32" alias "getwindowsdirectorya" (byval lpbuffer as string, byval nsize as long) as long
注釋：返回一個字符串，如“c:/windows”、“c:/winnt”
注釋：調用舉例：
注釋：dim strwindir as string
注釋：strwindir = getwindir()
private function getwindir()
dim windir as string * 100
