VB- 工程 -引用 - ADO 2.0 ,建一个类DB，工程名设为 SQLCONN
以下是偶程序中的部分代码，大家有空可以试试
Option Explicit
Public strError As String
Public Conn As New ADODB.Connection
Public Rs As New ADODB.Recordset
Public Property Get ErrorString() As String
ErrorString = strError
End Property
Public Function Conn_Open(strSQLServerName, strSQLDBUserName, strSQLDBPassword, strSQLDBName)
Dim strCon As String
Set Conn = New ADODB.Connection
On Error GoTo errHandler:
strCon = "Provider=SQLOLEDB;Server=" & strSQLServerName & ";User ID=" & strSQLDBUserName & ";Password=" & strSQLDBPassword & ";Database=" & strSQLDBName & ";"
Conn.Open strCon
errHandler:
strError = "错误源：" & Err.Source & vbCrLf & "描述：" & Err.Description
Exit Function
End Function
Function GetRootID(ByVal ClassID)
Dim query
query = "select class_ID,RootID from tblCategory where class_id='" & ClassID & "'"
Set Rs = Conn.Execute(query)
If Not (Rs.EOF And Rs.BOF) Then
GetRootID = Rs("RootID")
Else
GetRootID = ClassID
End If
Rs.Close
Set Rs = Nothing
End Function
编译后，在ASP中这样用
function GetRootID(byval id) ' 获取根类ID号
set S_DB = server.CreateObject( "SQLCONN.DB")
S_DB.Conn_Open strSQLServerName,strSQLDBUserName,strSQLDBPassword,strSQLDBName
GetRootID = S_DB.GetRootID(id)
Set S_DB=nothing
end function
