Hi guys.
i'm currently doing a simple clock program nothing much like the one from microsoft "DATE & TIME PROPERTIES" i just add text clock + calendar, the question is why the program consume memory too much 17MB ! microsoft date & time properties only about 3 ~ 4 mb. pls give some thought, thanks. |

VB.Net application required NET Framework runtime to run ,
just like JAVA with Java runtime which is hungry for memory & CPU usage. I Guess, that normal for WIN32 .Net Application Try Imagine , Last time I have been demo complex VB.net app on a client's PC which only has 64MB. T_T |

No matter how you trim it, you basically need a nominal usage of around 10~15MB for that (minimumal) framework run-time, and few MB for your app.

Here come with my dirty trick!
Try to call FlushMemory() in every XX seconds then you can see the effect. Remember, this is DIRTY way. It might NOT REALLY reduce memory usage but i think no harm to try. CODE Public Class MemoryManagement Private Declare Function SetProcessWorkingSetSize Lib "kernel32.dll" ( _ ByVal process As IntPtr, _ ByVal minimumWorkingSetSize As Integer, _ ByVal maximumWorkingSetSize As Integer) As Integer Public Shared Sub FlushMemory() GC.Collect() GC.WaitForPendingFinalizers() If (Environment.OSVersion.Platform = PlatformID.Win32NT) Then SetProcessWorkingSetSize(Process.GetCurrentProcess().Handle, -1, -1) End If End Sub End Class |
