 Posted: Fri Sep 26, 2008 3:56 am Post subject: How do i Import in MSVC++ (C) ? __declspec( dllimport ) |
 |
|
Is this correct ? cause i can\\\'t get it to work:
| Code: | #define DllImport __declspec( dllimport )
DllImport void WINAPI GetPhysicallyInstalledSystemMemory(
__out PULONGLONG TotalMemoryInKilobytes
); |
and btw, Dark Byte why does my application crash when i use GetPhysicallyInstalledSystemMemory in Delphi ?
this is what i did:
| Code: | type
PULONGLONG = ^ULONGLONG;
procedure GetPhysicallyInstalledSystemMemory(kbAmount: PULONGLONG); external kernel32 name \\\'GetPhysicallyInstalledSystemMemory\\\';
ULONGLONG = UInt64;
{$EXTERNALSYM ULONGLONG}
ULARGE_INTEGER = record
case Integer of
0: (
LowPart: DWORD;
HighPart: DWORD);
1: (
QuadPart: LONGLONG);
end;
kb: PULONGLONG;
GetPhysicallyInstalledSystemMemory(@kb);
//ShowMessageFmt(\\\'Total Physicaly RAM: %d\\\', [kb]); |

How are you introducing backslashes into shit you copy and paste even?
Client Requires Windows Vista SP1.
Server Requires Windows Server 2008.
Header Declared in Winbase.h; include Windows.h.
Library Use Kernel32.lib.
DLL Requires Kernel32.dll.
Just make sure you have windows.h included, and are linking against kernel32.lib. Call it as usual. And of course, you have to meet those requirements (as well as anyone that runs it)

You're over-complicating this.
include windows.h...
#include <windows.h>
then just link against kernel32, set it in the linker options or just do it like (you're probably already linking against it by default to begin with):
#pragma comment(lib, "kernel32.lib")
Then just call it.

import is for loading custom dlls in your project (apart from Loadlibrary)
export is for exporting (making custom dlls).

it won't work, weird!
| Code: | #include <windows.h>
#include <stdio.h>
#pragma comment(lib, "kernel32.lib")
void main(void)
{
ULONGLONG kbRAM;
GetPhysicallyInstalledSystemMemory(&kbRAM);
printf("Total Physical Ram: %li\n", kbRAM);
} |

use int main
Look at it under the debugger, what is it returning?
