Hi James,
There are two links to the source code further up in this message thread.

yes, I download it. But, as Stefan wrote, the source code of the function GetSntp() is not present. :(

But the function GetSntp() is missing, maybe you can contact the author

I was able to get it working by linking the .lib file then adding an INCLUDE "TSNTP.PRG"


The sorce of Jeff with the sntp.lib, work with any ntp server, but over the 32 requests always returns "fail"

This is my last test with the change, every test, of the ntp server:
(is the same if the time between 2 requests is 1 sec. or 5 min. o also 30 min.)
(is the same if renew the object oSntp)

I can not see errors for this limit and i think that probably the snpt.lib in tsntp.rar contain the GetSntp() linkable to the xharbour object but it is created with the limit, for this reason I search the source code of sntp.lib

As Stefan wrote: "maybe you can contact the author" does anyone know the author? his email address?

Thanks in advance.

My apologies, Ugo. I didn't notice you were looking for a missing section of code.

Ugo,

maybe the author is WengSheng, as mentioned in the source, but I don´t know how to contact him.
kind regards

I did some searching and I found a number of references to a WenSheng (not WengSheng) in Harbour and xHarbour forums. But, there were no email addresses.

This is the email id attached to those posting in Harbour Forum Postings

wen.ssbbs@gmail.com

This ssbbs is our forum member also I think. And previously I got SMART.LIB from him.
Please look at this posting where he mentioned about his email id as:

ssbbs_at_mail_zzz_com_tw
change _at_ to @


change _zzz to .zzz ...

search.php?st=0&sk=t&sd=d&keywords=ssbbs

Just now I found a forum maintained by him:

Remesh,

Yes, I found that forum too. The code posted is the same one we have here, but it doesn't not contain the source to the GetSNTP() function.

I just revisited the forum and noticed that there is an Email button at the bottom of the message.

Mr.James,

Just now I wrote an email to him.
Let us wait for him to come to our support,
with the source code of his GETSNTP() function.

The friend about "Ugo" have contact me and my replay is like:
---8<-----------------------------------------------------------------------

about sntp.lib, you can use tlib.exe to list obj, like:
c:\>tlib sntp.lib ,sntp.txt

and you will to view:

//---------------------
Publics by module

sntp size = 1396
_HB_FUN_GETSNTP

tsntp size = 2420
_HB_FUN_TSNTP
//---------------------

you can get GETSNTP.obj use tlib.exe like:
c:\>tlib sntp.lib *sntp ,sntp.txt

and you will get sntp.obj,

the 'sntp.obj' is use Borland C++ 5.5 to compile and you can link into
your winApp not limit harbour or xharbour.

and you can get 'tsntp.prg' source code from my website!!

Its a long time since I don't mess with ASM but if needed I can help :-)

Who is the author of sntp.obj ? Using http://astrobase.bajaobs.hu/astrobase/dos/dosuitil/objtoasm.zip we can get its ASM source code and from there is not very much difficult to figure the original C code: objtoasm.exe stnp.obj

If this violates any copyright, please say it and I will remove it, thanks:
