I am just beginning development of a new app and I need a little advice on
the best way to go about doing something.
The app is a project management tool for a construction company. Users in
the field will need to do remote updates both receiving and submitting data
back to the main office. I can't just make it a live web app because the
users will have to be able to work off line and sync data later (presumably
with a VPN connection).

I open an fstream in read-only mode, read till the end, then try to
sync() before seeking to position 0 & reading again. But the sync
fails. I discovered that clear()ing the stream before the sync causes
the sync to work. Seeking to position 0 before the sync doesn't seem
to help.
If you look at sync() as simply invalidating the read buffer (isn't
that right?), isn't it illogical for it to fail in this situation?
Besides sync()...

Hi All:
We're rolling out 3 DB2 (8.2 on LUW) platforms for branch offices, each
of these are going to have the same schema. These are all going to be
non-federated systems.
I need some advice / pointers on keeping the DDL's in sync with each other.
I'm going to have a development machine in my office that I first apply
any schema / stored-procedure changes to, then would like to roll out

Can anyone provide any pointers or code examples for Coding an app to use
ActiveSync to sync between SQL CE and SQL 2000 / MSDE
I want the app to use ActiveSync and to be a Windows form app on the PC and
with a widest target platform (ie. XP home, so no IIS), therefore using IIS
for Sync is not really an option (?)
Thanks

Hi,
What does ArrayList.Synchronized really do for an ArrayList?
Is that equal to add lock(this) for all its public methods and properties?
Not just for Add()/Insert()/Remvoe()/Count, but also for Item (this)?
Normally,do I need sync at all? Isn't that true without sync the program can
run faster?

Hi,
I'm going to develop a socket communication between an instrument (running
CE 5.0 with Compact Fraework V2) and a PC. As the instrument should only
connect to one PC at a time I believe that the sync version of the socket
should be the easiest - or what??? (please tell if I'm wrong).
Are there anyone who is able to point to a Server and Client example code in
C# VS2005 (I've only been able to find a C++ version) ???

I am reading TC++PL3 and on page 644 it is mentioned:
"Flushing an istream is done using sync(). This cannot always be done
right. For some kinds of streams, we would have to reread characters
from the real source - and that is not always possible or desirable.
Consequently, sync() returns 0 if it succeeded. If it failed, it sets
ios_base::badbit (21.3.3) and returns -1. Again, setting badbit might
trigger an exception (21.3.6). A sync()...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
