[RESOLVED] List of db providers

Hi All,

How do I view the list of all db providers available on my machine using VB code?

Thanks in advance!

i hope from the registry you can read the details...

But could you suggest some VB code to do this?

Try

VB Code:

Option Explicit
 
Private Declare Function SQLDataSources% Lib "ODBC32.DLL" (ByVal henv&, _
ByVal fdir%, ByVal szDSN$, ByVal cbDSNMax%, pcbDSN%, ByVal szDesc$, _
ByVal cbDescMax%, pcbDesc%)
 
Private Declare Function SQLAllocEnv% Lib "ODBC32.DLL" (env&)
 
Private Const SQL_SUCCESS As Long = 0
Private Const SQL_FETCH_NEXT As Long = 1
 
Private Sub Form_Load()
Dim lngGetDBProviders As Long
Dim sDSNItem As String * 1024
Dim sDRVItem As String * 1024
Dim sDSN As String
Dim iDSNLen As Integer
Dim iDRVLen As Integer
Dim lHenv As Long     'handle to the environment
 
   If SQLAllocEnv(lHenv) <> -1 Then
      Do Until lngGetDBProviders <> SQL_SUCCESS
         sDSNItem = Space(1024)
         sDRVItem = Space(1024)
         lngGetDBProviders = SQLDataSources(lHenv, SQL_FETCH_NEXT, sDSNItem, 1024, iDSNLen, sDRVItem, 1024, iDRVLen)
         
         sDSN = Left(sDSNItem, iDSNLen)
         If sDSN <> Space(iDSNLen) Then
            Combo1.AddItem sDSN
         End If
      Loop
      Combo1.ListIndex = 0
   End If
End Sub

That works. Thanks a lot!
