Reduce the memory usage.

Ok, there has been a number of complaints about programs written in the .NET Framework using lots of memory. Here is a way to reduce it using P-Invoke.

You need to import the function SetProcessWorkingSetSize.

<DllImport("kernel32.dll")> _
Public Shared Function SetProcessWorkingSetSize(ByVal handle As IntPtr, _
        ByVal min As Int32, _
        ByVal max As Int32) _
        As Boolean
End Function

Now call the function. You can place this in the constructor.

Dim proc As Process = Process.GetCurrentProcess()
Me.SetProcessWorkingSetSize(proc.Handle, -1, -1)

C# Version

[DllImport("kernel32.dll")]
public static extern bool SetProcessWorkingSetSize(System.IntPtr handle, int min, int max);

Process proc = Process.GetCurrentProcess();
SetProcessWorkingSetSize(proc.Handle, -1, -1);

Also, make sure you have a reference to System.Diagnostics and System.Runtime.InteropServices.

Why not using MaxWorkingSet of the Process?

[DevGrp]

Well, I never thought of that but I'll try.

Is there a remarkable difference while using this function ?

[DevGrp]

I tried it and it reduced a program from 15 mb to 4 mb.

[Pirate]

Great . I'll try it too soon . Thanks

I doubt that this function be useful in oridinary situations. If you have enugh memory, then why not let the program expand itself? I think the .NET memory manager is smart enough to shrink memory usgae when there is not enugh memory, that's just a guess though.

tell that to ur crazy clients when they are used to 10mb progs and they see 30mb ones

I wouldn't call garbage collection "smart"
