- DBF 文件位于
C:\dbase\clip53\PRG\stkmenu\WPACK3\ - 调用 DBF 文件
WPACKS.CFG（故意不是 .DBF）
ActiveX EXE 中用于打开数据库和记录集的 VB6 代码：
Function OpenDatabase(sFile As Variant, Optional sProvider As Variant = "Provider=Microsoft.Jet.OLEDB.4.0") As Variant ' ADODB.Connection
Dim nErr As Long
Dim sErr As String
Dim oConnection As Object 'ADODB.Connection
Set oConnection = CreateObject("ADODB.Connection")
On Error Resume Next
oConnection.open sProvider & ";Data Source=" & sFile
nErr = Err.Number
sErr = Err.Description
On Error GoTo 0
If nErr <> 0 Then
Err.Raise OPENDATABASE_E_NOTFOUND, , sErr
End If
Set OpenDatabase = oConnection
End Function
Function OpenRecordSet(ByRef oDb As Variant, sQuery As Variant, Optional bCmdText As Boolean = False) As Variant ''ADODB.Connection ADODB.Recordset
Const adOpenForwardOnly As Long = 0
Const adOpenStatic As Long = 3
Const adOpenDynamic As Long = 2
Const adOpenKeyset As Long = 1
Const adLockOptimistic As Long = 3
Const adCmdText As Long = 1
Dim oRecordSet As Object 'ADODB.Recordset
Set oRecordSet = CreateObject("ADODB.RecordSet")
If bCmdText Then
oRecordSet.open sQuery, , , adCmdText
Else
oRecordSet.open sQuery, oDb, adOpenKeyset, adLockOptimistic
End If
Set OpenRecordSet = oRecordSet
End Function
访问这些方法的脚本看起来有点像 VBScript。它是 VBScript，但由前面提到的 ActiveX EXE 执行，它使用 MSScript 控件并有一大堆对象可供脚本引擎使用。一种 VBScript-on-steroids 方法。
uses database
uses system
dim db
dim rs
set db = database.opendatabase("C:\dbase\clip53\PRG\stkmenu\WPACK3\","Provider=Microsoft.Jet.OLEDB.4.0;Extended Properties=dBase III;User ID=Admin;Password=")
set rs = database.openrecordset(db, "SELECT * FROM WPACKS.CFG",true)
system.consolewriteline rs.recordcount
我的问题是，The connection cannot be used to perform this operation. It is either closed or invalid in this context.当它遇到oRecordSet.open sQuery, , , adCmdText（我从 Microsoft 网站获得的）时，我一直在收到。
这有点烦人。
