用setup api安装modem成功后,在拨号连接里无法使用
我用setup api安装modem成功了,设备管理器可以正常看到这个modem,也可以正常检测,但在拨号连接里就是无法使用,老是提示找不到modem。如果我用硬件向导装modem就可以用。是不是modem驱动安装完还要在注册表登记什么?大虾指教啊,江湖救急!

痛苦挣扎后几个小时终于解决了。原来我是在modem安装完后再修改注册表键AttachTo使Modem绑在一个端口上,后来发现这是不行的,因为Modem安装过程中有一个向RAS注册的过程,必须在这个过程之前设置好AttachTo。但在SetupDiCallClassInstaller(DIF_INSTALLDEVICE,)之前AttachTo所在的主键还没有生成,没办法设置AttachTo,最后写了一个CoInstaller了事。

可否把你的CoInstaller部分代码发给我参考一下,我在这儿遇到的问题和你的很相似,谢谢! 我的mail: EricGaoxp@hotmail.com |

to gzytom 其实很简单,在安装前我把需要绑定的端口名称放在注册表某个地方下(我这里用的是HKCR\\Environment\\MDMCOM),然后在CoInstaller里读出这个值。用共享内存或者其他什么方式也可以的,不过我觉得用注册表方便。 DWORD CALLBACK ModemCoInstallProc ( DI_FUNCTION InstallFunction, HDEVINFO DeviceInfoSet, PSP_DEVINFO_DATA DeviceInfoData, PCOINSTALLER_CONTEXT_DATA Context ) { if(InstallFunction == DIF_INSTALLDEVICE) { char szInstanceID[255]; char buffer[1024]; DWORD cbData; HKEY hKey; char szComPort[10] = { 0 }; if(RegOpenKey(HKEY_CURRENT_USER , \"Environment\" , &hKey)==ERROR_SUCCESS) { cbData = sizeof(szComPort); if(RegQueryValueEx(hKey , \"MDMCOM\" , NULL , NULL , (LPBYTE)szComPort , &cbData)==ERROR_SUCCESS) { if(SetupDiGetDeviceInstanceId(DeviceInfoSet , DeviceInfoData , szInstanceID , 1024 , NULL)) { if(GetOsType() < OS_NT4) strcpy(buffer , \"System\\\\CurrentControlSet\\\\Services\\\\Class\\\\\"); else strcpy(buffer , \"SYSTEM\\\\CurrentControlSet\\\\Control\\\\Class\\\\\"); cbData = 1024 - strlen(buffer); if(RegQueryDeviceProperty(szInstanceID , NULL , \"Driver\" , NULL , (PBYTE)(buffer + strlen(buffer)), &cbData)==ERROR_SUCCESS) { if(RegOpenKey(HKEY_LOCAL_MACHINE, buffer,&hKey)==ERROR_SUCCESS) { RegSetValueEx(hKey , \"AttachedTo\", 0 , REG_SZ , (LPBYTE)szComPort , strlen(szComPort)); RegCloseKey(hKey); } } } } RegCloseKey(hKey); } } return NO_ERROR; } [编辑 - 8/18/03 by gzytom] |

98下确实是不能用,因为setupapi.dll使用了一些NTDLL.DLL的函数导 入,98下没有的,即使拷过来也不能用。 我的意思就是怎么让这个回调函数于你的主程序组合在一起。我想要实现运行这个程序后,就可以指定串口和INF文件,自动安装标准33K的调制解调器。无需用户在去选择和干预。 不知能不能给你的主程序也拿出来让大家学习学习。 下面是DDK下根据指定的INF和HardWareID来自动安装驱动的函数例程,请问如何将它和你的回调组合在一起使用,达到上述目的? BOOL InstallRootEnumDriver(IN LPTSTR HardwareId, IN LPTSTR InfFile,OUT PBOOL RebootRequest OPTIONAL) { HDEVINFO DeviceInfoSet=0; SP_DEVINFO_DATA DeviceInfoData; GUID ClassGUID; TCHAR ClassName[MAX_CLASS_NAME_LEN]; DWORD err; if (!SetupDiGetINFClass(InfFile,&ClassGUID,ClassName,sizeof(ClassName),0)) { return DisplayError(TEXT(\"SetupDiINFClass\")); } DeviceInfoSet=SetupDiCreateDeviceInfoList(&ClassGUID,0); if (DeviceInfoSet==INVALID_HANDLE_VALUE) { return DisplayError(TEXT(\"SetupCreateDeviceInfoList\")); } DeviceInfoData.cbSize=sizeof(SP_DEVINFO_DATA); if (!SetupDiCreateDeviceInfo(DeviceInfoSet,ClassName,&ClassGUID,NULL,0, DICD_GENERATE_ID,&DeviceInfoData)) { DisplayError(TEXT(\"CreateDeviceInfo\")); goto cleanup_DeviceInfo; } if(!SetupDiSetDeviceRegistryProperty(DeviceInfoSet, &DeviceInfoData, SPDRP_HARDWAREID, (LPBYTE)HardwareId, (lstrlen(HardwareId)+1+1)*sizeof(TCHAR))) { DisplayError(TEXT(\"SetDeviceRegistryProperty\")); goto cleanup_DeviceInfo; } if (!SetupDiCallClassInstaller(DIF_REGISTERDEVICE, DeviceInfoSet, &DeviceInfoData)) { DisplayError(TEXT(\"CallClassInstaller(REGISTERDEVICE)\")); goto cleanup_DeviceInfo; } // // The element is now registered.

to gzytom : 哦,我明白你的意思了。98下也有setupapi.dll,而且好像还没有什么函数不可以用吧?DDK下那个例子除了一个函数不能用:UpdateDriverForPlugAndPlayDevices,它是在newdev.dll里的,其他都可以用。其实这个UpdateDriverForPlugAndPlayDevices也可以用SetupDiXX类函数替代。下面是我的主程序的一个片断,仿照DDK写的,98下可以有条件的正常运行(见我后面的解释): BOOL FindExistingDevice(IN LPGUID lpGUID , IN LPCTSTR lpszHardwareID , OUT LPTSTR lpszInstanceID OPTIONAL) { HDEVINFO hdi = NULL; SP_DEVINFO_DATA hDev = { 0 } ; hDev.cbSize = sizeof(SP_DEVINFO_DATA); DWORD dwEnumIndex; char buffer[1024]; DWORD cbData; BOOL fFound = FALSE; try { if((hdi = SetupDiGetClassDevs(lpGUID , NULL , NULL , 0))==NULL) throw STException(\"SetupDiGetClassDevs\"); dwEnumIndex = 0; while(SetupDiEnumDeviceInfo(hdi , dwEnumIndex++ , &hDev)) { if(SetupDiGetDeviceRegistryProperty(hdi , &hDev , SPDRP_HARDWAREID , NULL , (PBYTE)buffer , 1024 , &cbData)) { char *p; for (p=buffer;*p&&(p<&buffer[cbData]);p+=strlen(p)+sizeof(char)) { if (stricmp(lpszHardwareID,p)==0) { printf(\"Found!

RegCloseKey(hKey); } } return ret; } 上面的代码结合我先前贴出的CoInstaller可以在2k/xp下完整地解决安装Modem 的问题。在98下有两个问题,一个是对某些设备的驱动在运行到SetupDiCreateDeviceInfo时会弹出新硬件安装的wizard,十分讨厌。不过好像Modem没有。解决办法也不难,对于会弹出wizard的设备,可以通过直接写注册表完成创建过程(也幸好98下可以直接修改enum)。 第二是98下不支持Co-Installer,实在不知道怎么及时地设置Attach键值,以致装完后拨号网络认不出Modem, 需要重启后才认。这是我目前没办法解决的。望哪位大虾可以指点迷津。 [编辑 - 8/22/03 by gzytom] |

十分感谢你的回信。
GUID_MODEM是指Modem的Guid还是你的MODEM的GUID呢? 另外安装的这个MODEM是内MODEM还是虚拟MODEM |

谢谢俩位的慷慨解囊,不知你们是用在什么MODEM上的?我是用在CDMA MODEM上的。 gzytom你的代码我试过,我将GUIDMODEM代入的是MODEM的ClassGUID {4D36E96D-E325-11CE-BFC1-08002BE10318}。但是在运行到SetupDiClassNameFromGuid函数时报了一个错误0xe0000206。不知为什么,另外不知你coinstall这方面是在那学的,这方面的资料很少,大部分是E文的。 EricGaoxp你的代码我试一试再说。 |

to:gzytom,EricGaoxp 我的也是CDMA Modem啊,//hand,呵呵。0xe0000206是指不合法的 类。怎么你的机子连Modem的类都没有。自己用写注册表方法手工添加应该也行的。不过我想不会的,是不是你的DEFINE_GUID写错了?coinstall不是很复杂的东西,msdn就有,不过e文是肯定的了。EricGaoxp的代码就可以不使用coinstaller了,一直没考虑过SetupDiCreateDevRegKey这个函数,原来有这个妙用。 |

原来都是用在CDMA MODEM上的呀!有缘有缘
MODEM的ClassGuid不是4D36E96D-E325-11CE-BFC1-08002BE10318吗 我用DEFINE_GUID(GUID_MODEM,0x4D36E96D,0x0e325,0x11ce,0xbfc1,0x08,0x00,0x2b,0xe1,0x03,0x18); 写的有什么错误吗? 另外你不知你用过DDK下的那个例子程序(通过.inf安装驱动程序)在调用UpdateDriverForPlugAndPlayDevices时在WIN2000下返回0xe0000203,但在XP返回0,这个ERROR又是什么意思? gzytom 其实在2000下可以设置Enum权限,然后修改它的键值(98可直接修怍),不用通过setupapi |

看了各位大侠的帖子,感触颇深。我现在在做GPRS MODEM,用了一根USB数据线连接手机,在PC机上虚拟了一个串口,现在软件编写完成,可是MODEM的添加却仍然需要用户手动添加,非常麻烦。我们自己做了一个MODEM的inf文件,不知道怎么在setup过程中就把MODEM添加到USB数据线虚拟的那个串口上去。
