I am writing an Compact Framework 2.0 application in C# for a CE 4.2 device.  
I need to programmatically connect to the Internet via Dial Up Networking.  
I have Internet Explorer set up to where it automatically connects (dials via 
DUN) to the Internet when attempting to go to a web site.  However, when I 
use HttpWebRequest (i.e. Webreqest - post); it does not automatically connect 
to the Internet if not connected.  I need to connect first, then my program 
can connect to the Internet.  I though .NET would automatically connect like 
IE.  Thus apparently I need to manually connect to the Internet in my 
program. 

In the past I used the Connection Manager in eMbedded C++, however, I cannot 
use this since it references cellcore.dll, which does not exist since my 
device is a 
PDA and not a cell phone.  Is there a managed API I can call to 
programmatically connect to the Internet.  I know I can shell execute 
"rnaapp.exe -eDUN", where DUN is the name of my Dial Up Networking 
connection.  However this is awkward since it prompts the user to click "OK" 
to actually dial.  I do not want the user to get prompted; I just want to 
automatically connect.   

Also, what managed function do I call to see what the current IP address is 
of my CE device?

Thank you.

There is no way to use RAS or GPRS on a PDA. It has to be a phone edition 
device.

There must be a more elegant way to programmatically connect to the Internet 
on a CE device via Dial Up Networking.  I am able to programmatically connect 
to the Internet by doing a shell execute of "rnaapp.exe -eCellular".  This 
brings up the "dial" dialog box and the user has to click "OK" to actually 
connect to the Internet.  Thus, I know you can do it.  I am just wondering if 
there is a way to dial into the Internet so the user doesn't see anything 
(i.e. doesn't have to click on "OK) to start the dial.  Is there another way 
I can invoke a dial up connection and force it to dial, not requring the user 
to select OK (or anything else)?  Also, what Framework function should I use 
to see what the IP address is of the device, once it is connected?

I think that you should be able to use TAPI to make a dial-up networking 
connection, but it's going to require some coding and I've never done that 
particular operation.  You could contact the device OEM, if it's a 
non-Pocket PC device, and see what they have for you.

Once you've connected, you should be able to use something like the 
OpenNETCF Smart Device Framework Adapter class to get the IP address.  You 
should probably check that site for some TAPI support, too.  I don't 
remember any specifically, but I could be wrong about that.  Searching the 
archives of this group using GoogleGroups for TAPI might help, too:
