the setup:
Webservice/WinClient application/SQL server.
VS.Net (visual basic) winform wizard creates a simple form
with load cancel cancelall and datagrid bound to a simple
Dataset with one Datatable. No coding by programer, All
wizardry. User starts app, opens form, adds (4) records
and clicks update.

OK i have came to the conclusion that since this app will be run on multiple computers that loading a complete database and then updating on exit is a moot point. I have tried several ideas submitted, but i am unable to get one of them to work completely. Here is the code i had before i realized that when i filled the dataset in the form load procedure that it would "ruin, replace, mess up" the dataset named the same thing on the other form....

Hi all,
Would someone be able to tell me the most 'graceful' way of removing
unwanted rows from a dataset based on a condition prior to update? OR,
resetting the rows all to unchanged after they are initally added to the
recordset.
I create a dataset, which begins empty after the initial .Fill.
Then I create several rows with some default information, leaving one

Hello group,
what would be the best way to do the next thing: I've got a grid form with
about 15000 records, when I double click a row a detail form is opened and
the user can modify and save the record, this all works just fine, then the
user closes the detail form and ofcourse I want to show his modifications in
the grid form, but now my question is what's the best way to do this without
completely reloading the dataset that holds the...

I have this scenario:
1. XML file with schema and data is created from SQL Server tables. XML file
contains 6 tables, some of them have rows, some of them are empty.
2. XML file is given to the person with Pocket PC.
3. XML file is used to populate DataSet on the Pocket PC.
4. User adds new rows, changes values, deletes some rows.
5. Altered dataset is saved back to XML file.
6. XML file is given back to the person who initially created...

I'm trying to create an application that will have multiple users
working off a table on a SQL server. Since multi users will be
updating different records at any given moment, how can i get those
changes and merge them into my current Dataset. I've been playing
around with the GetChanges method and Acceptchanges but they just dont
seem to be pulling over the changes and updating my Dataset. Maybe if
someone could give me a sample of...

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

Hi there,
Can anyone explain the following (very) simple scenario.
1) I make an exact copy of my "DataSet" and delete one record from a given
table (in the copy)
2) I invoke "DataSet.GetChanges()" on the above copy and pass the results to
"DataSet.Merge()" on the original copy
3) If I now inspect the original copy, it shows that the record has *not*
been deleted from the table. However, a call to "GetChanges()" does show my

Hello there,
I have the following code; I do this as a work around for a
dataset.haschanges method which doesnt appear to work correctly either
For Each dt As DataTable In myDs.Tables
If Not dt.GetChanges(DataRowState.Added) Is Nothing Then hasChanges=true
If Not dt.GetChanges(DataRowState.Modified) Is Nothing Then
hasChanges=true
If Not dt.GetChanges(DataRowState.Deleted) Is Nothing Then

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.
