bcb版的弟兄们，版主们，大家进来帮忙，讨论一个较深的问题

[jianlinlong]

有一个系统用到硬件卡，在win98有盘上播放一切正常。到无盘（用的是明智无盘系统）上运行后有就时常会出现死机和蓝屏的现象。蓝屏显示该硬件卡的驱动访问某个地址冲突，按任一键后又回到了无盘win98。但是此时该硬件卡的驱动的部分功能已经失效。。。。。。。严重影响了系统的运行.

我现在想，是否能写一个监视程序，它能检测到这个硬件卡, 一但发现有错误，就让系统重新装载。（或者说弄一个程序，凡win98的异常它都能够知道)

现在卡了，要监视硬件驱动，我摸不着门道！

[kingcaiyao]

是我写错了,应将SetupDiEnumDevice改为:
SetupDiEnumDeviceInterface

[xinghf]

找一下板卡的SDK

[jianlinlong]

十分感谢 kingcaiyao(AKing), 不过我还是编译不过

[C++ Error] Unit1.cpp(41): E2268 Call to undefined function 'SetupDiEnumDevice'

我看DDK的Help也只有SetupDiEnumDeviceInfo,SetupDiEnumDeviceInterfaces。好像没有提到SetupDiEnumDevice

我真是太菜了！

[jianlinlong]

巨晕，[Linker Error] 'D:\DOCUMENTS AND SETTINGS\ADMINISTRATOR\桌面\DRV_CONTROL\SETUPAPI.LIB' contains invalid OMF record, type 0x21 (possibly COFF)

用Borland自带的coff2omf转换也不成功:

[jianlinlong]

在上面的链接错误之前我将 SetupDiEnumDevice 改成:
SP_DEVINFO_DATA dev_dat;
SetupDiEnumDeviceInfo(hCard, 19, &dev_dat);
BOOL status = SetupDiEnumDeviceInterfaces(hCard,
&dev_dat,
&CardGuid,
19/*Index*/,
&DeviceInterfaceData
);//注意这里的Index参数，指的是你的设备序列号

对吗？

[domustdo]

学习！

[tccsdn]

上面说的硬件卡是什么东西呀

[RomanticProgrammer]

AKing乃真英雄也。^_^。

[jianlinlong]

看来俺水平对这个东东还是相差太远，麻烦 kingcaiyao(AKing)兄 帮我看看下面的代码错在哪？

void __fastcall TForm1::Button1Click(TObject *Sender)
{
DWORD ReqLength;
DWORD Flags=DIGCF_PRESENT|DIGCF_DEVICEINTERFACE;
//GUID CardGuid={0000,000,{00,00....}};//你硬件的GUID,可以从驱动程序的安装文件或注册表中找到
GUID CardGuid = StringToGUID("{4d36e96c-e325-2233-bfc1-08002be10318}");
HANDLE hCard=0;//操作硬件卡的句柄
PSP_DEVICE_INTERFACE_DETAIL_DATA DeviceDetailData;
SP_DEVICE_INTERFACE_DATA DeviceInterfaceData;
DeviceInterfaceData.cbSize = sizeof(SP_DEVICE_INTERFACE_DATA);
hCard=SetupDiGetClassDevs(&CardGuid,NULL,NULL,Flags);
if(hCard==INVALID_HANDLE_VALUE)
{
::MessageBox(0,"Invalid Parameters!","Error",MB_OK|MB_ICONERROR);
return;
}

// BOOL status = SetupDiEnumDevice(hCard,NULL,&CardGuid, 19/*Index*/,&DeviceInterfaceData,&ReqLength,
// NULL);//注意这里的Index参数，指的是你的设备序列号
SP_DEVINFO_DATA dev_dat;
SetupDiEnumDeviceInfo(hCard, 19, &dev_dat);
BOOL status = SetupDiEnumDeviceInterfaces(hCard,
//&dev_dat,
NULL,
&CardGuid,
19/*Index*/,
&DeviceInterfaceData
);//注意这里的Index参数，指的是你的设备序列号

if (!status)
{
::MessageBox(0,"Failed to enumurate the specified device!","Error",MB_OK+MB_ICONERROR); /*********每次执行都从这退出****/
::CloseHandle(hCard);
return;
}
SetupDiGetInterfaceDeviceDetail(hCard,&DeviceInterfaceData,NULL,0,&ReqLength,NULL);
DeviceDetailData=(PSP_INTERFACE_DEVICE_DETAIL_DATA)new char[ReqLength];
if(DeviceDetailData)
{
::MessageBox(0, "ERROR NOT ENOUGH MEMORY!","Error",MB_OK+MB_ICONERROR);
::CloseHandle(hCard);
return;
}
status=SetupDiGetInterfaceDeviceDetail(hCard,&DeviceInterfaceData,DeviceDetailData,ReqLength,&ReqLength,NULL);
if(!status)
{
::MessageBox(0,"Failed to get interface detailed data", "Error",MB_OK+MB_ICONERROR);
delete DeviceDetailData;
DeviceDetailData = NULL;
return;
}
ShowMessage(DeviceDetailData->DevicePath);
//DevicePath就是你要得到的参数有了DevicePath就好像有了设备的符号名，比如：COM1,COM2等，这样你就可以用
//CreateFile,ReadFile,WriteFile来和你硬件卡的驱动程序进行通信。有些设备制造商在开发驱动程序时可能就为该设备建立一个符号名，如最常见的\\\\..\\EZUSB等，但根据你所提供的情况，只能通过接口来与它的驱动程序进行通信
}
//---------------------------------------------------------------------------

[jianlinlong]

硬件卡的GUID我是找对了，Index我看也没有不对，可是每次都在

/*********每次执行都从这退出****/

那段代码就退出了，难!

[kingcaiyao]

一般与驱动程序通信就是上面的代码，因为我的机器上也没有硬件卡，但我写的这段程序的确可以与我机器上其它设备如：IP Modem(USB口）进行通信，你可以设个断点一步一步调试。

[kingcaiyao]

GUID我知道你不会找错，但你的设备序列号有没有找错???
它位于注册表中:HKEY_LOCAL_MACHINE\CurrentControlSet\Class\你设备的GUID,然后在设备类的下面有若干个子键，0000，0001等，你可以从这些子键中找到你的设备。如果在0000的子键中找到你的设备，那么就表明在你的机器上你的设备在同类设备中的序列号0，依次类推。

[jianlinlong]

to kingcaiyao(AKing) :

你能不能把包含 CDeviceInterface 的 devintf.h (devintf.＊)发到我的邮箱 [e-mail] ? 你以前写的那段代码我比较容易理解些。

对你的帮助我十分的感谢!

听课

[jianlinlong]

这几天忙着把程序重新分析一翻，所以没有再试了（水平还不够呀）。

以后有时间再慢慢来试，真佩服AKing的功力，他是真正的King呀!

再一次谢谢AKing的帮助

[gfh_79_0]

佩服！佩服，
向AKing学习。

[kingcaiyao]

楼上的，严重了，只要你多看看书一样可以做到。
