friends,
i have a table USERS with PEN number,PASSWORD string as fields. in my login screen when i till up and click login cmd-button nothing happens.
when i hit login it shold open DETAILS form.
the code for Login cmd button is given below:

Private Sub Command7_Click()
Dim uname As Long
Dim passwd As String
Form.Refresh
If Me!Text1 = "" And Me!Text2 = "" Then
Me.SetFocus
Me!Text1.SetFocus


Else
uname = Me!Text1
passwd = Me!Text2
If (uname = DLookup("[PEN]", "USERS", "[PEN]= " & Me!Text1.Value) And passwd = DLookup("[PASSWORD]", "USERS", "[PASSWORD]= '" & Me!Text2.Value & "'")) Then
DoCmd.OpenForm ("DETAILS")
Else
End If
End If
End Sub

better to give your controls meaningful names - is it called Command7? so is the code running?

and this code can be better written as

If DCount("*", "USERS", "[PEN]= " & Text1 & " AND [PASSWORD]= '" & Text2 & "'")=1 then

Also if PEN is not numeric, you need to include single quotes as you have for password

sure ajax. this is a crude one. i am making an original one with meaningful names. thanks for your suggestions.

a couple of suggestions:
If Me!Text1 = "" And Me!Text2 = ""
..... doesn't look correct to my eye and guessing it should be: If Me.Text1 = Me.Text2

it often is better to do the DCount of a query - and put the criteria in the query: rather than put the criteria in the DCount clause. This is because it is much easier to test. One can manually fire the query to see if it is working as one intends.

I'm guessing that

If Me!Text1 = "" And Me!Text2 = "" Then

is meant to check for the lack of data in those Controls...but it's actually only checking for Zero-Length Strings! 'Empty' Controls, in Access, are usually Null. To check for both ZLSs and Nulls, you can use a number of hacks, including

If Nz(Me!Text1, "") = "" And Nz(Me!Text2, "") = "" Then

And as Ajax said, the exact syntax depends on the Datatypes of Fields in the Where Clause.
