VC++如何获取操作系统类型及显卡信息？小弟找了一下午了，还没解决

[e251396]

我是个donet程序员，但一个项目中需要用到VC来获取相关信息，但我一点也不懂VC，所以请高手能帮忙一下。谢谢各位了。

没人知道吗?

获取操作系统版本:GetVersionEx,例子 http://msdn.microsoft.com/en-us/library/ms724429(VS.85).aspx

//显卡信息：要得到哪些信息？

[e251396]

芯片型号，显存及驱动程序的版本之类的啊

[oyljerry]

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class
下面依此读取所有的项，直到找到Class键的值为Display（显卡）或MEDIA（声卡），
找到后读取下面的键值

也可以通过WMI来读取。。。

如果在没有装驱动的情况下读取信息，估计需要通过读取主板bios，显卡bios等来得到。。

GetSystemInfo()好像得不到这么多信息
试试
Win32_DisplayConfiguration

[oyljerry]

Display Adapters
Class = Display
ClassGuid = {4d36e968-e325-11ce-bfc1-08002be10318}

Multimedia
Class = Media
ClassGuid = {4d36e96c-e325-11ce-bfc1-08002be10318}

#include "stdafx.h"
#include <stdlib.h>
#include <windows.h>
#include <setupapi.h>

int main(int argc, char* argv[])
{
DWORD dwIdx = 0;
SP_DEVINFO_DATA adapterData;
DWORD dwType = 0;
DWORD dwBuflen = 0;
PUCHAR pBuf = NULL;
HDEVINFO hScsi = INVALID_HANDLE_VALUE;
GUID guidScsiRaid = {
0x4D36E97B,
0xE325,
0x11CE,
{0xBF, 0xC1, 0x08, 0x00, 0x2B, 0xE1, 0x03, 0x18}
};

BOOL bret = FALSE;

hScsi = SetupDiGetClassDevs(&guidScsiRaid
, NULL, NULL, DIGCF_PRESENT);

adapterData.cbSize = sizeof(SP_DEVINFO_DATA);

for(dwIdx = 0; SetupDiEnumDeviceInfo(hScsi, dwIdx, &adapterData); dwIdx++)
{
SetupDiGetDeviceRegistryProperty(
hScsi,
&adapterData,
SPDRP_DEVICEDESC,
&dwType,
NULL,
0,
&dwBuflen
);

if(ERROR_INSUFFICIENT_BUFFER == GetLastError())
{
pBuf = (PUCHAR)malloc(dwBuflen);
if(SetupDiGetDeviceRegistryProperty(
hScsi,
&adapterData,
SPDRP_DEVICEDESC,
&dwType,
pBuf,
dwBuflen,
NULL
))
{
printf("%s\n", pBuf);
}

free(pBuf);
pBuf = NULL;
}
}

SetupDiDestroyDeviceInfoList(hScsi);

return 0;
}

能给出具体的代码吗?我没写过这样的代码.

[oyljerry]

把上面的guidScsiRaid 换成{4d36e96c-e325-11ce-bfc1-08002be10318} ，上面的代码基本上就差不多了

我知道java中能获取系统信息 没用过.net
应该有吧

{
