Hej

jeg har brug for, at hente de frie resourcer på en windows 9x maskine (Free
GDI, Free SYS og Free User).
Hvordan kan jeg det ?

Brug nedenstående unit


unit SystemResources;
interface

uses
Windows, SysUtils;

function GetSystemResources: Integer;
function GetGDIResources: Integer;
function GetUserResources: Integer;
function RunningLowOnResources: Boolean;

implementation
{***************************************************************}

var
hKernel32Dll: HWND;
_QT_Thunk: procedure; cdecl;
hUserExe: HWND;
_GetFreeSystemResources: function(const nResourceType: Word): Word;
stdcall;

function _LoadLibrary16(pLibraryName: PChar): HWND; stdcall; external
kernel32 index 35;
procedure _FreeLibrary16(hInstance: HWND); stdcall; external kernel32 index
36;
function _GetProcAddress16(hInstance: HWND; pProcName: PChar): Pointer;
stdcall; external kernel32 index 37;

function GetFreeSystemResources(const nResourceType: Word): Integer;
var
arrThunk: array[0..32] of Word;
nFreeSystemResources: Word;
begin
Result := -1;
if Win32Platform <> VER_PLATFORM_WIN32_NT then
begin
if Assigned(_GetFreeSystemResources) then
begin
arrThunk[0] := hUserExe;
asm
push nResourceType
mov edx, _GetFreeSystemResources
call _QT_Thunk
mov nFreeSystemResources, ax
end;
Result := nFreeSystemResources;
end;
end;
end;

function GetSystemResources;
begin
Result := GetFreeSystemResources(0);
end;

function GetGDIResources;
begin
Result := GetFreeSystemResources(1);
end;

function GetUserResources;
begin
Result := GetFreeSystemResources(2);
end;

function RunningLowOnResources;
const
MINIMUMRESOURCES = 10;
var
nSystemResources, nGDIResources, nUserResources: Integer;
begin
Result := False;
if Win32Platform <> VER_PLATFORM_WIN32_NT then
begin
nSystemResources := GetSystemResources;
nGDIResources := GetGDIResources;
nUserResources := GetUserResources;
Result := ((nSystemResources <= MINIMUMRESOURCES) and (nSystemResources
> -1)) or ((nGDIResources <= MINIMUMRESOURCES) and (nGDIResources > -1)) or
((nUserResources <= MINIMUMRESOURCES) and (nUserResources > -1));
end;
end;

initialization
begin
if Win32Platform <> VER_PLATFORM_WIN32_NT then
begin
hKernel32Dll := LoadLibrary(kernel32);
if hKernel32Dll > 0 then
begin
@_QT_Thunk := GetProcAddress(hKernel32Dll, 'QT_Thunk');
if Assigned(_QT_Thunk) then
begin
hUserExe := _LoadLibrary16('user.exe');
if hUserExe >= 32 then
@_GetFreeSystemResources := _GetProcAddress16(hUserExe,
'GetFreeSystemResources');
end;
end;
end;
end;

finalization
begin
if Win32Platform <> VER_PLATFORM_WIN32_NT then
begin
if hKernel32Dll > 0 then
begin
if hUserExe >= 32 then
_FreeLibrary16(hUserExe);
FreeLibrary(hKernel32Dll);
end;
end;
end;

end.

Jeg takker mange gange.
