Hello,
I really like the finditer() method of the re module. I'm having
difficulty at the moment, however, because finditer() still creates a
callable-iterator oject, even when no match is found. This is
undesirable in cases where I would like to circumvent execution of code
meant to parse out data from my finditer() object.
I know that if I place a finditer() object in an iterative for loop,
the loop will not execute, but is there some...

Hi,
I just noticed your post in the "C# memory problem: no end for our problem?"
thread.
In the post you implied that I do not how the garbage collector works and
that I mislead people. Since the thread is over a month old, I decided to
start a new one with my response.
Please see my comments inline.

Hello,
I want to delete duplicate rows in a table when no primary key is
defined.
For eg: If we have table1 with data as below,
Suma 23 100
Suma 23 100
I want to delete a row from this table and retain only one row.

When I do this:
foreach( Button btn in myForm.Controls )
An exception is raised when no buttons exist. I would simply expect
execution to continue after the foreach loop (just as would be the case
with a regular for loop when the second expression is false when the
loop begins).
Is there an explanation for this?

Hey Fans!
Perhaps you can help me...
I am using MS Access 2003. I have tried a number of things to get rid of the text #Error from appearing on form fields when no data present.
Tried the NZ function, also tried the IIF function, told it to give me zero if no data found, so far it seems to lead to nowhere land. What are your thoughts? Hopefully it's not very simple and I missed the boat, hee hee...
Thanks for your help!

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,...
