Let's say I have an html form with 20 or 30 fields in it. The form
submits the fields via POST to a php page which updates a table in a
database with the $_POST vars. Which makes more sense?
1) simply UPDATING the values for all fields in the table, whether or
not any particular field has actually changed
2) running a second SELECT statement and comparing the $_POST vars to
the returned values, and only UPDATING those that have...

I've got a simple windows form with some bound textboxes
and Save button. Each texbox is bound to column in a table
in an Access database. The form fills fine - all the
fields show the correct data for the record I load. So
then I change the contents of one of the textboxes and
click on the Save button. The button's event handler then
calls the data adapter's Update method and I check the
return value. Nada-zilch-nothing. I even put a...

How can I update the datatable with the datagrid values after the datagrid
itself has been modified.? I assume it's not automatically done.
Thanks.

I need to update a parent .aspx screen from a popup and close the
popup. Normally I would use
'window.opener.location.reload(true);self.close();' but i need the
parent window not to reload or else data that the user has already
entered will be lost during the IsPostBack.
I need the 'Apply' button on the popup to trigger the 'Update' button
on the parent screen. The script ive seen...

Is there a way to use your own image in place of the automatic one that ASP
uses when doing editing in your DataGrid pages?
We already have a style of button we are using and would like to be
consistant.
Thanks,
Tom.

Hi guys,
I've been trying to implement an editable datagrid and i have been
succesful up to the point where i can update my datagrid row by row.
However what used to happen was that once i updated one row, all of
them were updated so i immediatelly figured out that i have to include
the id of every entry in the update statement. This is where the
problem is raised. My database is an Access database. The table i am
updating contains a Date...

The guts of the below asp.net vb code was pieced together from another
thread - all due credit to it's original author. Thank you!
I've modified it to maintain a small local Microsoft 2000 access DB
via a datagrid control.
The add and delete functions work great, but the edit does not actually
update the database. I put in some displays and apparently on the first
item in the grid gets set during editing, all others come back empty???

I have a datagrid control that I've inherited from the base datagrid control (Source below).
I am applying a datatable style onto the datatable that I assign as my datasource.
All of my column but one are set as readonly=true. The writeable column does not update when I'm editing it. Is there something
different that I need to be doing to update this data? Also, how do I get the "new row" to not appear at the bottom of the
datagrid?...

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 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...
