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
