Application compiled with Win2K/XP DDK works fine. But doesnt work with WIN98 DDK

Hi,
I got a requirement to develop an application which checks the status
of NIC card, enables or disables it. I used SetupDi...,
Cm_Get_Devnode_Status_Ex, Getadapterinfo api for this purpose and
compiled with Windows DDK 2k/xp on VC6. They worked perfectly on
Windows 2k/XP machines

The probblem started when I tried to compile it for windows 98
machines. In order to compile for Windows 98, I installed VC++ 4.2 &
win98 ddk (DDK doc said it is compatible only with VC4.2 compiler) on a
Windows 98 machine. Unlike win2K/XP DDK, the Win98 DDK didnt contain
the "Iphlpapi.h". So, I downloaded the PSDK2003 and installed it. When
I tried to compile the same code in this setup, I got the following
errors.


1) There were lot of conflict in typedef declaration between Win98 DDK
& PSDK2003 headers. After struggling for couple of days i managed to
compile it.

2) Then came the linker errors:

---------------
Linking...

D:\PSDK2003\Lib\iphlpapi.lib : fatal error LNK1106: invalid file or
disk full: cannot seek to 0x3d50d14b
---------------

when i referred MSDN, it said the reason could be lack of space or
corrupted hardisk. But I have more than 500 MB left and 'thorough'
scandisk didnt find any problemwith the hardisk. Then i comented
GetAdaptersInfo() which required this Library. On compiling, I got
another Link error...

---------------
error LNK2001: unresolved external symbol "unsigned long __stdcall
CM_Get_DevNode_Status_Ex(unsigned long *,unsigned long *,unsigned
long,unsigned long,void *)"([email protected]@[email protected])
---------------

But the library path and include path are properly set. Don't know
wwhat is causing the error!

When i checked Win2K/XP, I saw that there is a separate include
directory for driver development (c:\winddk\3790.1830\inc\ddk\wxp\) and
for application interface with devices (c:\winddk\3790.1830\inc\wxp\).
But in Win98 DDK, there is only one include directory!!

Does that mean only driver (.drv,.sys files) can be developed using
the Win98 DDK? I am stuck here, and really confused about how to
proceed! Your help will be highly appreciated.


Thank you in advance.

Did you see this note concerning the CM functions?

"If you intend that your device installation application run on Windows
9x/Me, or Windows NT 4.0 or earlier, and you use the CM_Xxx functions, be
sure that CfgMgr32.lib appears before SetupAPI.lib in the sources file. If
your application is intended to run only on Windows 2000 or a later NT-based
operating system, you can omit CfgMgr32.lib."

I haven't used the CM functions on 98/ME myself, but I have used the SetupDi
functions. There I use VS .NET 2003 for all platforms. The major wrinkle
that I found in using SetupDi on 98/ME is that 98/ME only support the ANSI
character set. You must implement the wide-character versions using
character conversions if you need them.

Good luck,

Do you really need to support win98?
The win98 requirement is often just cut-and-paste from some previous
product documents.
I remember several times when after telling to management that support for
win9x adds development time and even can delay product shipping,
they simply removed this requirement.

I Thank evry body for their replies.

I tried putting CfgMgr32.lib before SetupAPI.lib and compiled it. But
still getting error.
---------------
Linking...

D:\PSDK2003\Lib\iphlpapi.lib : fatal error LNK1106: invalid
file or
disk full: cannot seek to 0x3d50d14b

Moreover, in the include path win98 ddk comes before PSDK 2003. when i
compiled the code with this include order it gave 47 errors. Then, I
put PSDK path before WIN98 DDK path and compiled the same code (
without cleanig the object files). To my surprise the no. of error
reduced. Then i kept repeating this process ( alternating include path
and compiling) which considerably reduced errors on each build and
finally compiled without errors.

I got the link errors mentioned in the original post only after this. I
think the LNK1106 error is becuase , VC 4.2 compiler was unable to
understand the PSDK2003 lib file format.

Anyway, I think ,I have to skip doing this development for WIN98

thanks again for evrybody's help

 

This is very possible, no surprise at all. You could PSDK contemporary to VC4.

Quite correct. The format of an import library changed in VC 6 in an
incompatible way.
