Wireless SSID - Is it Stored on Windows CE Device?

[mbrodsky]

I am in need of being able to programmatically detect the SSID of the router my Windows CE device is currently connected to.

Does anyone know if the SSID is stored either in the registry, or in a text file, or somewhere I can access (other than the built-in CE wireless application?)

Or, if you know how to programmatically access it with VB.net (for Compact Framework), that would be great too!

Thank you very much!!!

I already generated the SSID using this any one of this two method, try to modifie it in order to obtain exactly the string represinting the SSID and not only checking it's existing.
Sorry this source code is in c and not in vb. you can hide them in a dll as it was and call it from your vb application
you can visit this link to get further details

http://www.codeproject.com/useritems/DeviceInfo.asp

the building of the dll and others informations which can be obtained about the device.

wchar_t NameDev[256];

bool bRet = false;
const unsigned int iDim = (sizeof(NDISUIO_QUERY_OID) + (sizeof(unsigned char) * LENGHT_MAC));

memset(QueryBuffer, 0x00, iDim);
