我想在我的 VB6 应用程序中创建动态 DSN。我在我的 MODULE 中尝试了以下代码。使用以下 Microsoft 链接 - http://support.microsoft.com/kb/171146。
我的代码在这里-
Private Declare Function SQLConfigDataSource Lib "ODBCCP32.DLL" _
(ByVal hwndParent As Long, ByVal fRequest As Long, _
ByVal lpszDriver As String, ByVal lpszAttributes As String) _
As Long
Public Function PrepareDSN(strServerName As String, strDBName As String, strDSN As String, strDBUser As String, strDBUserPassword As String) As Boolean
On Error GoTo error_hdl
Dim boolError As Boolean
Dim strDSNString As String
PrepareDSN = False
strDSNString = Space(MAX_BUFFER_SIZE)
strDSNString = ""
strDSNString = strDSNString & "DSN=" & strDSN & Chr(0)
strDSNString = strDSNString & "DESCRIPTION=" & "DSN Created Dynamically On " & CStr(Now) & Chr(0)
strDSNString = strDSNString & "Server=" & strServerName & Chr(0)
strDSNString = strDSNString & "DATABASE=" & strDBName & Chr(0)
strDSNString = strDSNString & Chr(0)
If Not CBool(SQLConfigDataSource(0, _
ODBC_ADD_DSN, _
ODBCDriverDescription, _
strDSNString)) Then
boolError = True
MsgBox ("Error in PrepareDSN::SQLConfigDataSource")
End If
If boolError Then
Exit Function
End If
PrepareDSN = True
Exit Function
error_hdl:
MsgBox "PrepareDSN_ErrHandler::" & err.Description
End Function
这里我的函数“SQLConfigDataSource”总是返回false。请建议。
