ntdevHi,All:
I’ve a problem with SetupDiXXX API function on Windows 98(SE).When I call SetupDiGetClassInstallParams(…) it return error code:0x57(Invalid parameters…) Please see the source code blow:

void TestDrvInstall()
{
HDEVINFO hDevInfo;
GUID guid;
BOOL bSuccess;
char szClassName[MAX_PATH];
DWORD dwRequireSize = 0;
SP_DEVINFO_DATA sp_devinfo;
SP_CLASSINSTALL_HEADER sp_ClassInstall;

sp_ClassInstall.cbSize = sizeof(sp_ClassInstall);

bSuccess = SetupDiGetINFClass(
“C:\WINDOWS\Desktop\crasher\Driver\crasher.inf”,
&guid,
szClassName,
sizeof(szClassName),
&dwRequireSize
);
if(!bSuccess)
{
AfxMessageBox(“Get Inf class failed!”);
return ;
}

hDevInfo = SetupDiGetClassDevs(&guid,NULL,NULL,DIGCF_PRESENT);

if( INVALID_HANDLE_VALUE == hDevInfo )
{
AfxMessageBox(“SetupDiGetClassDevs failed!”);
return ;
}

sp_devinfo.cbSize = sizeof(sp_devinfo);
sp_devinfo.ClassGuid = guid;

> //******>> This call return error: Parameter invalid…why?

bSuccess = SetupDiGetClassInstallParams(
hDevInfo,
&sp_devinfo,
&sp_ClassInstall,
sizeof(sp_ClassInstall),
&dwRequireSize
);
if(!bSuccess)
{
AfxMessageBox(“Get install parameters failed!”);
return;
}

bSuccess = SetupDiCreateDeviceInfo(
hDevInfo,
“Crasher\0000”,
&guid,
“Crasher new SCSI Adapter”,
NULL,
DICD_INHERIT_CLASSDRVS,
&sp_devinfo
);
if(!bSuccess)
{
AfxMessageBox(“Create Device info failed!”);
return ;
}
}

Thank you in advance!

Regards!

Hi,
This is because the “sp_devinfo” is uninitialised
and this is be filled only in the
SetupDiCreateDeviceInfo() function. Try passing NULL
since this is optional

Cheers,
Jay

Your problem is that you are using the wrong setup library. For windows
9x systems you have to use the 16-bit library call setupx.lib. The
function you need is “DiCreateDeviceInfo” (see 98 ddk documentation for more
information). Also, your code has to be 16-bit code, i.e. you have to
user VC++ version 1.52, or cl.exe, or from the XP DDK disk in win_me
directory.
