Finding records in a DGrid using parameters from access table

I am a kenyan who is new in vb, and i have had this particular problem. I want to connect to an access table with parameters and allow the  user to find records by entering His/her paramerters from  a form.
Just how can I do that?
(SOME CODE MIGHT HELP)
NOTE: I AM USING ADO CODE.

I'm not clear on the question but it sounds like you just need to know when criteria is specified.

Example:
A form that has searching on customer, city and state.

The form would have text boxes TxtCustomer, TxtCity and TxtState.

When user presses an OK button to do the search, use the following code.

Dim SqlString as String, ValType as String, temp as String

SqlString = "SELECT * FROM TableName WHERE Customer IS NOT NULL"
If Len(TxtCustomer) Then
    temp = TxtCustomer
    ValType = GetValType(temp)
    SqlString = SqlString & " AND Customer ValType '" & TxtCustomer & "'"
End If
If Len(TxtCity) Then
    temp = TxtCity
    ValType = GetValType(temp)
    SqlString = SqlString & " AND City ValType '" & TxtCity & "'"
End If
If Len(TxtState) Then
    temp = TxtState
    ValType = GetValType(temp)
    SqlString = SqlString & " AND State ValType '" & TxtState & "'"
End If

You could also do date ranges using the "BETWEEN" reserved word for 2 text boxes.

Function GetValType(ByVal temp As String) As String
'You could use a check box with a value of 1 to do searches of "LIKE" and
'put your own percent signs before and after the values in the text box criteria
If Instr(temp, "%") Then
    GetValType = "LIKE"
Else
    GetValType = "="
End If
End Function

A mistake in above code
It should be SqlString = SQLString & " AND FieldName " & ValType & "'" & temp & "'"
