Hi,
Are the users modifying the same data? You might run into some serious
problems
if they can modify, delete and add new data offline.
For the syncronization, I would develop a web service. The web service can
be called
from your client, sending all data that was changed.

Hi,
I've got a simple console app that just reads an XML file into a DataSet
then prints out a description of each table in the DataSet, including
column names and row values for each column. I'm getting some strange
results depending the input XML file I use. I was wondering if somebody
could help me understand what is going on or point me to a good reference.
The code for my program looks like this:

Hi,
I need to pass a dataset to another win form along with a SqldataAdapter.
I don't want to recreate the SqlDataAdapter again either. So to pass to
another Win form in my windows form app, do I create the procedure to pass by
ref? Which means I don't need to add ByRef because it is defaulted by ref,
correct? And in the constructor of the win form that gets created. I need to
add in parameters a DataSet and SqlDataAdapter correct? What...

hello,
i have a web app that allows users to query our oracle db and produce a
dataset of report data. they then have the option to serialize this
data and store it in the database. later, then can re-run the report
and get fresh data. now, they would like to be able to compare the
fresh data to the stored data, getting a break-down of
added/deleted/changed rows.
on the surface, this sounded plausible -- by deserializing the stored

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:
