VB6編程中怎么取得硬盤分區(qū)信息

也許你并不了解硬盤分區(qū)信息應(yīng)該包括些什么,但如果你曾經(jīng)對(duì)硬盤分過區(qū),你或許對(duì)此有所了解,在此為各位介紹一個(gè)用VB編寫的獲取硬盤分區(qū)信息的程序。在這個(gè)程序中,它將詳細(xì)地告訴你:你的硬盤總?cè)萘俊⒎诌^幾個(gè)區(qū)、每個(gè)區(qū)的總?cè)萘俊⒓艾F(xiàn)在剩余的可用容量、硬盤分區(qū)表為幾位(即是FAT32還是FAT16),每個(gè)分區(qū)是幾個(gè)字節(jié)……怎么樣?夠完整詳細(xì)了吧!好的,就讓我們一起來看一下吧:
首先做準(zhǔn)備工作:在FORM1上新建二個(gè)LABEL(LABEL1和LABEL2)一個(gè)COMMAND1命令按鈕。然后輸入以下代碼:
Private Declare Function GetDriveType Lib
kernel32“Alias "GetDriveTypeA(ByVal nDrive As String) As Long
Private Declare Function GetDiskFreeSpace Lib“kernel32" Alias“GetDiskFreeSpaceA" (ByVal lpRootPathName As String, lpSectorsPerCluster As Long, lpBytesPerSector As Long, lpNumberOfFreeClusters As Long, lpTtoalNumberOfClusters As Long) As Long
Private Const DRIVE_FIXED = 3
Private Sub Form_Load() ‘作初始化設(shè)置
COMMAND1.Caption = “測(cè)試硬盤"
Form1.Caption = “測(cè)試硬盤程序"
Label1.WordWrap = True
Label1.Caption = “"
Label2.WordWrap = True
Label2.Caption = “"
End Sub
Private Sub COMMAND1_Click()
Dim DriveNum As Integer
Dim TempDrive As String
Dim X As Long
For DriveNum = 97 To 122 Step 1 ‘檢測(cè)從A-Z(盤符)
TempDrive = GetDriveType(Chr(DriveNum) & “:\")
Select Case TempDrive ‘如是3則表示是硬盤,測(cè)試你有幾個(gè)盤
Case 3: X = GetDiskSpace(Chr(DriveNum)) ‘調(diào)用子程序
End Select
Next DriveNum
End Sub
Public Function GetDiskSpace(DrivePath As String)
Dim Drive As String
Dim SectorsPerCluster As Long
Dim BytesPerSector As Long
Dim NumberOfFreeClusters As Long
Dim TotalClusters As Long
Dim Check As Integer
Dim DiskSpace
Dim diskTotal
Static AllDiskTotal As Long
Static NUM As Integer
NUM = NUM + 1 ‘分幾個(gè)區(qū)的計(jì)算
Drive = Left(Trim(DrivePath), 1) & “:\"
Check = GetDiskFreeSpace(Drive, SectorsPerCluster, BytesPerSector, NumberOfFreeClusters, TotalClusters)
If Check <> 0 Then
DiskSpace = SectorsPerCluster * BytesPerSector * NumberOfFreeClusters
‘這是一個(gè)分區(qū)磁盤剩余空間的計(jì)算公式
DiskSpace = Format$(DiskSpace, “###,###") ‘以規(guī)定格式顯示,如732,324,231
diskTotal = SectorsPerCluster * BytesPerSector * TotalClusters
‘這是一個(gè)分區(qū)磁盤總?cè)萘康挠?jì)算公式
diskTotal = Format$(diskTotal, “###,###")
AllDiskTotal = AllDiskTotal + diskTotal ‘整個(gè)硬盤的總?cè)萘?br> Label1.Caption =“你的硬盤總?cè)萘繛?” & Format$(AllDiskTotal,“###,###") &個(gè)字節(jié),即:” & Left(AllDiskTotal, 1) & . & Mid(AllDiskTotal, 2, 1) &“G,一共分了”& NUM &“個(gè)區(qū),其中:"
Label2.Caption = Label2.Caption & UCase(DrivePath) & “盤的整個(gè)容量為:" & diskTotal &“個(gè)字節(jié)" & ",其剩余磁盤空間為:“& DiskSpace & " 個(gè)字節(jié),磁盤已FAT“& SectorsPerCluster & ",每個(gè)分區(qū)為:“& BytesPerSector & "個(gè)字節(jié)。“& vbCrLf & vbCrLf”
End If
End Function
OK!現(xiàn)在你運(yùn)行一下,你是否滿意它?
注:以上程序在中文WINDOWS98,中文VB6.0企業(yè)版中調(diào)試通過。
