Hi,
The GetIpForwardTable funct is found in iphlpapi.dll

from MSDN :

GetIpForwardTable
[This is preliminary documentation and subject to change.]

The GetIpForwardTable function retrieves the IP routing table.

DWORD GetIpForwardTable (
PMIB_IPFORWARDTABLE pIpForwardTable, // buffer for routing table
PULONG pdwSize, // size of buffer
BOOL bOrder // sort the table?
);

Parameters
pIpForwardTable
Pointer to a buffer that, on successful return, contains the IP routing table as a
MIB_IPFORWARDTABLE structure.
pdwSize
Specifies the size of the buffer pointed to by the pIpForwardTable parameter.
If the buffer is not large enough to hold the returned routing table, the function
sets this parameter equal to the required buffer size.
bOrder
Specifies whether the returned table should be sorted.
If this parameter is TRUE, the table is sorted by:
1. Destination address
2. Protocol that generated the route
3. Multipath routing policy
4. Next-hop address
in that order.

Return Values
If the function succeeds, the return value is NO_ERROR.

If the function fails, use FormatMessage to obtain the message string for the returned error.

QuickInfo
Windows NT: Requires version 4.0 SP4 or later.
Windows: Requires Windows 98 or later.
Windows CE: Unsupported.
Header: Declared in iphlpapi.h.
Import Library: Use iphlpapi.lib.

At Microsofts MSDN center they give a C program snippet to get (and change ) the default gateway @ http://msdn.microsoft.com/library/de...iphelp_14.asp.
However to me it seems to want the function 'GetIpForwardTable' which I can't find in wsock32.inc or win32api.inc. Does anyone know how to get this fucntion ?

Regards
Adrian

Scott - yep, thats the hard way !!! Also it'll pop up a black box in the middle of the screen.
Lance - thanks, I've got the subnet mask but the data it returns doesn't give the gateway but it does look promising.

a search of the bbs for "subnet" gives me http://www.powerbasic.com/support/pb...ad.php?t=24848 - it may do what you want?

You could always shell to a cmd.exe and run "ipconfig /all" and screen scrape all the data off, tons of it in there...

That's the hard way I'm sure...

Hi all, in the past there's been alot of posts regarding getting the computers IP address (or addresses). For your next challenge , how could I get the subnet mask and default gateway settings for the respective IP addresses?
For the purpose of this post , I'm using Windows 2000.

Any help most gratefully received.

Adrian
