使用方法:

1.新建Access Adp项目
2.在模块中新建一个模块，粘贴以下代码
3.新建一个登录窗体，调用即可

Public Function saConnect(ByVal strServer As String, ByVal strDatabase As String, _
ByVal strUsername As String, ByVal strPassword As String) As Boolean

On Error GoTo err

Connect:
Dim strCn As String

strCn = "PROVIDER=SQLOLEDB.1;"

'strCn = strCn & "Workstation Id = HY"
strCn = strCn & "DATA SOURCE=" & strServer & ";"
strCn = strCn & "INITIAL CATALOG=" & strDatabase & ";"
strCn = strCn & "USER ID=sa;"
strCn = strCn & "PASSWORD=;"

strCn = strCn & "PERSIST SECURITY INFO=TRUE;"
strCn = strCn & "Use Procedure for Prepare=1;"
strCn = strCn & "Auto Translate=True;"
strCn = strCn & "Packet Size=4096;"

'Debug.Print strCn
CurrentProject.OpenConnection strCn

theConnect = True

Exit Function
