Hello, I'm currently studying for 70-316 as well, and so far Amit Kalani's book is looking good. I already used his book to study for 70-315 and passed it with 962 points, so I think his method really works for me. I also did as much background reading as I could in MSDN and other sources like CodeProject to fill in my knowledge of C# in general and related topics like SQL, IIS and so on. As far as practice exams are concerned, I do think they're useful. For 70-315, I tested myself using the PrepLogic practice exam that came with Kalani's book, as well as the practice exam in the Microsoft official Self-Study guide. Neither was quite the same as the actual exam, but they did make me scratch my head and look up some points I'd missed in MSDN. Emma

hi, under the WIN32API we have CreateMutex function... u can use this function to check whether the appilcation is already running.. by its return values u can re-invoke the existing one... Public Declare Function CreateMutex Lib "kernel32" Alias "CreateMutexA" (lpMutexAttributes As SECURITY_ATTRIBUTES, ByVal bInitialOwner As Long, ByVal lpName As String) As Long this is the declaration for that function.(from API text viewer) u can also find help in MSDN abt this. http://support.microsoft.com/default.aspx?scid=kb;en-us;258088[^] use this link... heres a vb sample.... Option Explicit Const ERROR_ALREADY_EXISTS = 183 Public Declare Function CreateMutex Lib "Coredll" Alias "CreateMutexW" _ (lpMutexAttributes As Long, _ ByVal bInitialOwner As Long, _ ByVal lpName As String) As Long Public Declare Function GetLastError Lib "Coredll" () As Long Private Sub Form_Load() Dim error_code CreateMutex CLng(0), 1, App.Title If GetLastError() = ERROR_ALREADY_EXISTS Then MsgBox "Already running", vbOKOnly, App.Title App.End Else 'run the application MsgBox "OK to run" End If End Sub all the best.. - thanks and regards, Basavaraj P.Umadi

Back when I took mine, Microsoft used to provide practice exams that closely mimicked the real exams. I've not seen those available of late. If you know the subject material well enough (eight months is highly questionable), practice exams are not necessary. Transcender.com[^] is another resource. "Opinions are neither right nor wrong.
