在程序中如何得到以下信息

[whitelion]

是否要通过查注册表
我的电脑->右键菜单->属性->设备列表（winnt与98不一样）
我想知道如何知道这些硬件信息列表

[Behard]

学习

[whitelion]

还有别的方法吗

查下MSDN中的例子。有相应的程序。

The following code fragment demonstrates how to display a list of all installed hardware devices:

#include <stdio.h>
#include <windows.h>
#include <setupapi.h>
#include <devguid.h>
#include <regstr.h>

int main( int argc, char *argv[ ], char *envp[ ] )
{
HDEVINFO hDevInfo;
SP_DEVINFO_DATA DeviceInfoData;
DWORD i;

// Create a HDEVINFO with all present devices.
hDevInfo = SetupDiGetClassDevs(NULL,
0, // Enumerator
0,
DIGCF_PRESENT | DIGCF_ALLCLASSES );

if (hDevInfo == INVALID_HANDLE_VALUE)
{
// Insert error handling here.
return 1;
}

// Enumerate through all devices in Set.

DeviceInfoData.cbSize = sizeof(SP_DEVINFO_DATA);
for (i=0;SetupDiEnumDeviceInfo(hDevInfo,i,
&DeviceInfoData);i++)
{
DWORD DataT;
LPTSTR buffer = NULL;
DWORD buffersize = 0;

//
// Call function with null to begin with,
// then use the returned buffer size
// to Alloc the buffer. Keep calling until
// success or an unknown failure.
//
while (!SetupDiGetDeviceRegistryProperty(
hDevInfo,
&DeviceInfoData,
SPDRP_DEVICEDESC,
&DataT,
(PBYTE)buffer,
buffersize,
&buffersize))
{
if (GetLastError() ==
ERROR_INSUFFICIENT_BUFFER)
{
// Change the buffer size.
if (buffer) LocalFree(buffer);
buffer = LocalAlloc(LPTR,buffersize);
}
else
{
// Insert error handling here.
break;
}
}

printf("Result:[%s]\n",buffer);

if (buffer) LocalFree(buffer);
}


if ( GetLastError()!=NO_ERROR &&
GetLastError()!=ERROR_NO_MORE_ITEMS )
{
// Insert error handling here.
return 1;
}

// Cleanup
SetupDiDestroyDeviceInfoList(hDevInfo);

return 0;
}
The following code fragment demonstrates how to retreive a set of all display adapters on a system.
hDevInfo = SetupDiGetClassDevs(
(LPGUID) &GUID_DEVCLASS_DISPLAY,
0,
0,
DIGCF_PRESENT);
The following code fragment demonstrates how to retrieve a set of all devices on the Peripheral Component Interconnect (PCI) bus.
hDevInfo = SetupDiGetClassDevs(NULL,
REGSTR_KEY_PCIENUM, // Enumerator
0,
DIGCF_PRESENT | DIGCF_ALLCLASSES );
Windows API functions that require a Device Instance Handle, such as the Config Manager set of API functions, can use the DevInst value in the structure SP_DEVINFO_DATA returned by the SetupDiEnumDeviceInfo function.



REFERENCES
SetupDi API calls are documented in the Windows 2000 Device Development Kit (DDK).

不过 ，您需要 DDK..

Microsoft Windows 2000 Driver Development Kit (DDK)

VB中的应用程序向导会生成一个“系统信息“
里面会有东西对你有帮助
