Hi,
I've downloaded the evaluation version.
Found in ethman en netui the sources needed to find the device name
and switch the mode to and from accesspoint
//switching the mode
if(iSelection == 2)
{
// Computer-to-computer
s_mode = Ndis802_11IBSS;
}
else if(iSelection == 1)
{
// infrastructure (access point) network
s_mode = Ndis802_11Infrastructure;
}
else if(iSelection == 0)\
{
// Any network (access point preferred)
s_mode = Ndis802_11AutoUnknown;
}
s_pWLanInfo->dwCtlFlags &= ~INTFCTL_CM_MASK;
s_pWLanInfo->dwCtlFlags |= (((DWORD) s_mode) &
INTFCTL_CM_MASK);
FillPreferredLV(s_pWLanInfo);
//get the devicename (I hope this will not change)
while (ReadMsgQueue(
hMsgQueue,
&sDeviceNotification,
sizeof(NDISUIO_DEVICE_NOTIFICATION),
&dwBytesReturned,
1,
&dwFlags))
{
PTCHAR ptcDeviceName = NULL;
// The device name should be in uppercase to query
NdisUIO
ptcDeviceName =
_wcsdup(sDeviceNotification.ptcDeviceName);
if (!ptcDeviceName)
{
DEBUGMSG(ZONE_ERROR, (TEXT("ETHMAN: Could not
allocate memory for string \"%s\"\r\n"),
sDeviceNotification.ptcDeviceName));
continue;
}
_wcsupr(ptcDeviceName);
I only hope it will work.
Regards
Laery

Then you probably don't have enough information to make a serious
attempt at
this. You could download the evaluation version of PB and go from
there...
