Hello
Some of the columns are empty, and must be turned into "nbsp;" so
that an empty cell is shown when displayed in HTML.
This code, however, doesn't work (meaning: I get an empty line instead
of "nbsp;"), but I don't know how else to loop through each column in
the current row:
========
$sql = "SELECT * FROM phones";
foreach($dbh->query($sql) as $row) {
foreach($row as $key =$val) {
if(!$val)
$val="nbsp;";
}
print $row['phones_name'] . "<p>";
}
========
Any idea why?
Thank you. 3 2574

Probably because $val isn't what you expect it to be. Find out what's
in $val for an empty column and test for that.
And BTW - the code is " ". You're missing the leading ampersand.

I didn't know that structure. Is it refering to the value's address?

Nice to know, although it doesn't look nice if the cell is empty and
the only one on the row: http://img407.imageshack.us/img407/6...ptycellrz0.jpg

A beginner in this area, I have been able to read a record from a
MySQL database and populate an HTML form (wow!). Now, my goal is to
allow the user to edit the contents of the form and then update the
record in MySQL.
The problem is, as soon as the "Update" button (type="submit") is
pressed, all of the data disappear from the form. How can that be
prevented?
Here is my code:

Hi again,
I have a gridview, when I get the selecteditem.cells for a column, if
the database column is Null or Empty, and I assign that to my web form
text control, the control reads " " instead of a blank.
Never had this happen before, but I am now using Asp.Net 2.0.
Ideas please?

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.

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,...
