Ping Utility for Windows CE

Environment: Windows CE 2.11+, Windows 2000, Windows NT, Visual C++ 6

Unfortunately, the HPC/PPC devices (running Windows CE) lack a ping utility. Therefore, because the HPC PRO SDK (version 2.11+) does have a subset of the ICMP functions, I was able to write my CEPing utility which can be helpful for checking the connection of CE devices to other friends ( CE devices or bigger machines ) on a TCP/IP network. In the case of lack of such utility it is possible to check if CE device is in the net by standard ping utility from some 'big'( PC ) computer. I didn't produce ceping for emulation mode because of the absence of ICMP functions for emulation mode.

In CEPing, I defined only a subset of the standard ping.exe parameters for simplicity. However, it would trivial to add any omitted functionality as I'e included the complete source code here. By default, CEPing functions like the standard ping utility with -a switch specified (it tries to resolve addresses to peer computers). But, obviously, that's not always possible. Therefore, there are time when you can't see the names of peer computers on the line under IP/Name editbox. Basically, it all depends on how you have WINS defined in the network properties Control Panel applet.

The problem is that without a WINS server definition, the gethostbyname() and gethostbyaddress() functions will return NULL. Therefore, in this case, it is only possible to check the IP address of peers and not resolve the name. The result of typing correct peer name in this case is "Wrong Name" answer on ping operation.

I checked the HPC (Jornada 680) with my PC with LP-E ethernet card and Xircom card. By default, Xircom installed my PC IP as a WINS server. Here is a table which describes the behavour of the gethostbyname() and gethostbyaddress() functions in different environment (based on the definition of the WINS settings).

V = resolution exist
X = no resolution

                    No WINS server  |     WINS defined      |  Wins defined as host PC
                       defined      |  host PC | others PC  |    host PC | others PC
gethostbyname()          X          |     V          V      |       V          X
gethostbyaddress()       X          |     V          X      |       V          X

As you can see from the figure above, the results of the ping are displayed in combo box and each string contains the number of connection attempts as well as the RTT (Round Trip Timetime)

  • Newer SDKs use IPHLPAPI.LIB instead

    Posted by bthomsen on 10/17/2008 12:33pm

    With SDKs newer than .NET 4.0, the icmplib.lib library is no longer included. Use the iphlpapi.lib library instead.

    Works great. Just remember to include the winsock.lib and the icmplib.lib under project settings. Thx. Btw: I am experiencing approx. 20 seconds cost pr. single call to Ping eventhough the ping time is about 600 ms. Is that what can be expected? Any comments appriciated.

      I tried to compile the code using Embedded visual c++ 4.0 but I always get an error message that is the following: C:\Documents and Settings\Administrator\Desktop\CE_DEV\ceping.rc(189) : fatal error RC1015: cannot open include file 'res\ceping.rc2'. Error executing rc.exe. I will appreciate if you can send me all missing files or the whole code, one that will work other than the one listed here online. Thanks in advance

  • now ported to pocketpc2002, eMVc++ 3.0, everything working.

    well, I just made a folder called "res" and placed there a rc2 and a ico file I borrowed form another projec.t usually, there's nothing specific in the rc2 file anyhow.
    then, I added the icmp.lib to the linker-settings, disabled the precompiled headers and then I compiled as release.
    now everything works.

    kindly regards
