I had some code that worked fine for several weeks, and then yesterday
it stopped working. I'm not sure what I did. Nor can I make out why it
isn't working. I'm running a query that should return 3 items from the
database. I then get a count of the return, which correctly tells me
that I've got 3 items. I then go into a for loop which I expect to
loop 3 times and print out the 3 items. Here is where things get
strange: it loops 3 times and...

Hi,
I need to display columns in a data grid based on 7 different queries. Now I
have 32 questions:
1. Is it possble to have 1 single data adapter with 7 queries & 1 data set
or do I need to have a separate data adapter & a separate data set for each
select query?
If thats possible then how?

I have an off-the-shelf app that uses an Access database as its
backend. One of the tables contains a field with an "OLE Object"
datatype. I'm writing some reports against this database, and I
believe this field contains data I need. When I view the table in
datasheet view, all I can see in this field is the string "Long
binary data".
So, I've got the problem of needing to extract data from this
field, but I don't know what format...

I am currently trying to work on a program and I found it more convient to
have a tempory object which would hold a copy of data loaded from a file so I
wouldn't have to work with the overhead of loading from a file repeatedly.
My problem is that when I store the temporary object to another object,
changing the temporary object or its data also changes the data of the other
object.
Example:
MyClass a=new MyClass(2), b=new MyClass(3);

Hi!
The question of type checking/enforcing has bothered me for a while, and
since this newsgroup has a wealth of competence subscribed to it, I
figured this would be a great way of learning from the experts. I feel
there's a tradeoff between clear, easily readdable and extensible code
on one side, and safe code providing early errors and useful tracebacks
on the other. I want both! How do you guys do it? What's the pythonic
way? Are...

Hi !
I get the error below sometimes when retrieving a big amount of data using Datadapter.Fill(dataset,"table"). But when I send the command Fill again, there is no error. Is it a fault of IBM.Data.DB2.iSeries; Version: v1.0.3705 (is there an newer one for OS/400 Version ist V5R3 ?) or is it a hardware faoult (memory of as400 or pc) ?

I have a DataGrid which displays data with the aid of a procedure.
I have tested the procedure inside the database and it is working
fine. The table inside the database has data that matches with the
parameter.
I have another procedure which adds another row to the table, which is
working fine inside the programming, and in the database.
However, I still cannot figure out what am I doing wrong with the
DataGrid configurations OR...

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...

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,...
