I've come across a limitation in unpickling certain types of complex
data structures which involve instances that override __hash__, and was
wondering if it was known (basic searches didn't seem to come up with
anything similar) and if there is a workaround for it short of
restructuring the data structures in question.
The fundamental issue rests with defining classes which override __cmp__
and __hash__ in order to be used as keys in...

I'm having some problems with an Access 2000 MDB file with a SQL Server 7
back end, using ODBC linked tables. I previously wrote about this, but am
reposting it with some additional information and in summary form, in hopes
that someone might have an idea about what's going on.
I am using a bound form which is losing data a significant portion of the
time. Basically, the form contains 6 fields and three subforms, as follows:

I am facing this problem....
I have to define a structure at runtime as the user specifies...
The user will tell the number of fields,the actual fields...(maybe
basic or array types or multiple arrays,etc)
I do not understand how to define the structure at run time.i.e.what
fields it will contain.

Hi,
I have a web application with a table to store terms and
conditions of a Company.
This may some times run into many pages and some times it may be just a
few sentences. It is a character text field. I want to know which Data
type I need to use so that it doesnt waste memory.
thanks in advance,

So I need to load lots of data into my database.
So I discover LOAD DATA INFILE.
Great! This little gem loads my CSV in blazing times (compared to
parsing the file and doing INSERT for each row). Its still slow on
large files, but just barely acceptable.
Only one problem. It truncates fields to 256 characters, even on a
text field.

I have what I think is a little strange...I have to get data from our
payroll system into a specific format (fixed record length) as a .txt
or .prn file only to upload to our 401k custodian.
I can get the data into Access (from Payroll) and write a query with
all the fields (inserting fields with spaces, as needed), but I can't
figure out how to get it to export to a .txt file - without the field
name header row.
I don't really ...

Dear Access Group:
This is the most basic and most embarrassing of questions, but I
cannot find where to change the data type of a text field that I have
in Access 2003 to a number field. I've searched high and low through
help databases and on the internet.
The directions say to :

Hi there!
I need a C++ library that can organize and write scientific (and
numerical overall) data in tables. I have been fighting with
std::ofstream and plain ASCII files, but it is difficult to position
columns by an offset, impossible to draw table borders etc. I am
currently thinking of a class that is able to write to an html file,
e.g. As far as I know, html offers much better text (and table)
layout. And the format is portable!...

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:

Here is the code in...

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,...
