Title: How to get memory values from Windows API
Question: I was about to create my own About dialog as the windows it self produces it... And there was the Memory available to Windows value...
Answer:
Here is the answer...
This is a function that provides the memory values of physical memory, Virutal Memory, PageFile memory (available and free)...
unit ugWinMemory;
(* unit by Uros Gaber; eMail: uros.gaber@powercom-si.com *)
interface
// set the types of memory to get
type TwmType = (wmAvailable, wmFree, wmVAvailable, wmVFree, wmPAvailable, wmPFree);
(* wmAvailable = physical memory total
wmFree = physical memory free
wmVAvailable = virtual memory total
wmVFree = virtual memory free
wmPAvailable = PageFile memory total
wmPFree = PageFile memory free *)
function GetWindowsMemory(typ: TwmType): string;
implementation
function GetWindowsMemory(typ: TwmType): string;
var memstatus: _MEMORYSTATUS;
str_tmp: string;
mem_stat: cardinal;
begin
GlobalMemoryStatus(memstatus);
if typ=wmAvailable then
mem_stat:=memstatus.dwTotalPhys;
if typ=wmFree then
mem_stat:=memstatus.dwAvailPhys;
if typ=wmVAvailable then
mem_stat:=memstatus.dwTotalVirtual;
if typ=wmVFree then
mem_stat:=memstatus.dwAvailVirtual;
if typ=wmPAvailable then
mem_stat:=memstatus.dwTotalPageFile;
if typ=wmPFree then
mem_stat:=memstatus.dwAvailPageFile;
mem_stat:=mem_stat div 1024;
GetWindowsMemory:=FloatToStrF(mem_stat, ffNumber, 18, 0)+' KB';
end;
end.
