I am still ignorant about Tkinter. This little program, after pressing
the "Go" eats more and more RAM, is it normal? Can it be avoided? (In
normal programs this is isn't a real problem).

generated the schema using vs.net and also the corresponding dataset. I can
load the config file (config.xml - below) and get all the data except for the
element attribute values. I cannot figure out why the attribute values return
a value of system.dbnull when the file contains values for those attributes.
The code is as follows:

I have in a form a datagrid that display a dataset, but if I start a new
thread that fill the dataset the program will crash, that's because the
dataset is not synchronized, is not thread safe.
I tryed to use the monitor.enter(dataset) and monitor.exit(dataset) befor
updating the dataset but was useless.
I think the problem is the paint method of the datagrid, that you can not
override, so you can not synchronize the dataset.

Why am I getting an error when I passed by ref a dataset to a new form? The
message reads "cannot convert from 'ref Paimport.unixAccount' to 'ref
System.Data.DataSet'.
Paimport is the name of the form where the dataset UnixAccount is created.
I created the dataset using the designer tool and not by code. So it's like
a type or class which I then declare an instance of it :
UnixAccoutns dsAccounts = new UnixAccoutns ();
I pass to a new...

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:
