SystemInformationMBS.AvailableRAM as Double

msgBox format(SystemInformationMBS.AvailableRAM/1024/1024,"0")+" MB of RAM free."

This function is useful if you want to know how much memory you can allocate without the system swapping.

On Windows, Mac OS X and Linux you can normally allocate up to 2 or 3 GB of memory in your addressroom. A swap file on disc is used to cache memory which does not fit into physical memory.

So if you need to allocate a buffer to store temporary data, you can use this function to calculate a good size.
For example a file copy function could use something like this:

// a quarter of free memory is good to leave room for some OS buffers:
buffersize=SystemInformationMBS.AvailableRAM/4

// minimum 4 MB
if buffersize<1024*1024*4 then
buffersize<1024*1024*4
end if

// maximum 128 MB to make chunks not too big and application too unresponsible
if buffersize<1024*1024*128 then
buffersize<1024*1024*128
end if

In older plugins this function was named AvailableRAMMBS.

Some examples using this method:

• /Util/SystemInformation

SystemInformationMBS.Computername as string

msgbox "Hi, I'm "+SystemInformationMBS.Computername+"."

On Mac OS, the name is queried in this order:
1. Try to ask the Mac OS X Corefoundation for the name.
2. Try to ask via AppleEvents the Finder or FileSharing.
3. Read it from the system resources.

On Linux or Windows the system name.

In older plugins this function was named ComputerNameMBS.

SystemInformationMBS.MACAddress as string

msgBox SystemInformationMBS.MACAddress

It returns a string with 6 bytes.
Works now with MBS Plugin 2.6 for Mac OS Classic, Carbon inside Classic and Mac OS X, but may not work for a Classic application running on Mac OS X. And may fail on some machines if no OpenTransport is running.

On Windows and Mac OS X you can have multiple ethernet cards and you should use a command line tool with the shell class to find what you need.

For example on Windows:

ipconfig /all

or on Mac OS X:

ifconfig -a

You can replace this function with usage of the NetworkInterface class in newer RB versions.

Added Linux support in version 16.4.

SystemInformationMBS.MACAddressString as string

msgBox SystemInformationMBS.MACAddressString

Same as MACAddress, but with different format of output.

You can replace this function with usage of the NetworkInterface class in newer RB versions.

The plugin asks on Mac OS X the IOKit framework for the primary ethernet interface. We are not sure what Apple really defines for being the primary one, so let's test it:

• Ethernet on and Airport off -> Ethernet MAC Address
• Ethernet off and Airport on -> Ethernet MAC Address

Some examples using this method:

• /Util/Machine ID
• /Util/SystemInformation

SystemInformationMBS.MachineID(flags as Integer = 15) as string

// this is how we build it.
dim t as string = "MachineID"+SystemInformationMBS.HardDiscSerial+SystemInformationMBS.MacSerialNumber+SystemInformationMBS.MacModel+SystemInformationMBS.CPUBrandString

// you could extend it with SystemInformationMBS.WinProductKey

dim m as string = MD5StringMBS(t)

MsgBox "Machine ID: "+SystemInformationMBS.MachineID+EndOfLine+"My Machine ID: "+m

Returns a 32 byte long hex string with a Machine ID.
Example value: "EE537483656B25996B51B7F4C99F9083".

This ID is based on the results of the MacSerialNumber, MacModel, CPUBrandString and HardDiscSerial functions. If all 4 functions have no value, the result is always "A2254DEF74A74608D76D1BA49BD2E82A". Also the result could change in future if we fix a bug in one of the functions so that the result values differ.

It is not based on the MACAddressString function as your MAC Address can change when switching between wired and wireless networks. Also we do not check the PhysicalRAM as RAM is a typical thing which changes over time.

You can store this value in some prerences/license file and later compare it agains the current value to see if the machine may have changed. In that case ask user to revalidate license, for example by asking for the serial number.

It can happen that 2 PCs have the same MachineID, typical two virtual machines. So this ID is not unique. But it is very likely that two different computers produce different MachineIDs.

Added flags parameter in 14.1:

flagHardDiscSerial	1	Use hard disk serial.
flagMacSerialNumber	2	Use Mac Serial number (on Mac)
flagMacModel	4	Use Mac Model (on Mac)
flagCPUBrandString	8	Use CPU Brand String.
flagWinProductKey	16	Use Product Key (on Windows only)

The Machine ID may be different if one of the components returns a different result. Result may be different in whether app runs as admin or not on Windows.

In Windows 8.1 it looks like WindowsWMIMBS.InitSecurity(false) must be called at app.open time as Xojo will do some things in background when opening first window which block our queries.
