Poor performance from vb.net

Question

Help I've developed a system using vb.net but the performance is so slow that it take almost 3 minutes just to load the log-in screen. The system contain around 150 forms and tens of crystal reports. This is the first time I am using VB.net and I have zero experience in vb programming. My guess is that the system is using too much memory as the whole system is under 1 exe. What can I do to breakup the system into smaller chunk? Thanks.

Try using this. Put it into a module and call the function like this: SaveMemory() Private Declare Function SetProcessWorkingSetSize Lib kernel32.dll (ByVal hProcess As IntPtr ByVal dwMinimumWorkingSetSize As Int32 ByVal dwMaximumWorkingSetSize As Int32) As Int32 Public Function SaveMemory() As Int32 GC.Collect() 'calls garbage collector GC.WaitForPendingFinalizers() 'collets and destroyes deallocated objects If (Environment.OSVersion.Platform = PlatformID.Win32NT) Then 'Checks the version of the OS Return SetProcessWorkingSetSize(Diagnostics.Process.GetCurrentProcess.Handle -1 -1) 'swaps one process for another End If End Function
