VB编写破解Access程序源代码

1、 首先是窗体代码 Option Explicit

Private Sub cmdOpenFile_Click() Dim sFile As String Dim sPasswd As String Dim sVersion As String

cmdOpenFile.Enabled = False

sFile = INNER_GetFileName(True, \请选择数据库文件\

If Len(sFile) > 0 Then Shape1.Width = 0 txtFileName = sFile txtVersion = \ txtPassword = \

sPasswd = INNER_GetAccessPwd(sFile, sVersion) txtVersion = sVersion txtPassword = sPasswd End If

cmdOpenFile.Enabled = True End Sub

Private Sub Form_Load() Shape1.Width = 0 End Sub

2、接着是模块代码 Option Explicit

#Const USE_DAO = 0 #If USE_DAO Then

Public gDAO As DAO.Database #Else

Public gADO As ADODB.Connection #End If

Public Function INNER_GetFileName(ByVal fbOpen As Boolean, _

Optional ByVal fsFilter As String, _

Optional ByVal fsDefaultExt As String, _ Optional ByVal fsDefFile As String, _

Optional ByVal fsDialogTitle As String) As String On Error GoTo ErrLabel Dim iReplace As Integer

With frmMain.CommonDialog1 If fsFilter = \

.Filter = \所有文件 (*.*)|*.*\ Else

.Filter = fsFilter

End If

.Flags = cdlOFNHideReadOnly Or cdlOFNExplorer .CancelError = True

.DefaultExt = fsDefaultExt

If fsDialogTitle <> \ If fsDefFile <> \ Do

If fbOpen Then .ShowOpen Else

.ShowSave End If

If Len(.FileName) = 0 Then Exit Function End If

If Not fbOpen Then

If Len(Dir(.FileName)) > 0 Then

iReplace = MsgBox(\代替存在的 \吗?\vbQuestion)

Else

iReplace = 0 End If

If iReplace = vbCancel Then Exit Function End If Else

If Not (Len(Dir(.FileName)) > 0) Then Exit Function End If

Loop While iReplace = vbNo If Not fbOpen Then

If iReplace = vbYes Then Kill .FileName End If End If

INNER_GetFileName = .FileName End With ErrLabel:

Select Case Err.Number Case 75

MsgBox Err.Description & \请重新选择文件路径!\ End Select End Function

Public Function INNER_GetAccessPwd(fsDBsee As String, fsRetVer As String) As String Dim sTemp As String
