I am trying to run a thread off of a form, and every once in a while the thread will raise an event for the form to read. When the form gets the event, the form will place the event into a dataset and display it on a datagrid that is on the form. The problem is that the thread will slowly take over all of the processor time. After about 8 events, the form will not even respond anymore. Here is the guts of my test code

Is it possible to do nested datagrids for Windows Forms?

I would not have thought that getting a DataGrid connected to a DataSet
(read in from an XML file) would be this complicated. I cannot get this to
work. I have read everything I could find and modeled all the examples
given but this grid just refuses to behave nicely.
The code is listed below as well as the XML schema and XML data.
The connection between the data set and grid seems to work just fine. What
won't work is the display...

Has anyone personally read and recommends a good book which includes good

areas.

I know this has been asked before but I have not seen it
answered. How would one implement nested datagrids in
windows forms based on the table relationships within a
dataset? Or, is there some setting that lets you
automatically display the details table (instead of the
relationship name) on the new expanded row of a datagrid?
I have seen it for ASP.NET, but is this doable for windows
forms?
Thanks in advance,

Hi,
In the VB.NET code behind ASP.NET, the programmer is able to directly
access the columns and rows associated with the datagrid. Why are
datagrids in VB.NET window forms so different? The only way I have
figured out how to manipulate the columns and rows in a datagrid is to
use data tables. So if I want to change any values contained in the
datagrid table or to hide or show different columns depending on
different criteria, I must...

I want to obtain the appearance of frozen columns as in an excel sheet so
thet the first two columns of the table remain in view at all times.
Example - I have a table of products - listed by Item and Line.
I want the Item and Line columns to remain visible whilst being able to
scroll the rest of the grid across to reveal other columns.
Ialso need the information to be present and synchronised with the rows
when I scroll down.

Apologies if this has come up before, but I can't find it if it has. I
am fairly new to .Net and am having problems with ghosts in the
datagrid.
Basically I have a find screen that accepts search criteria, then
interrogates a database to find all matching records. These are put
into a dataset, which has a dataview that is used as the datasource of
my datagrid, which is read only. The idea is that the user selects
which record they...

This is making me crazy!
vb.net 2003
I have two datagrids, datasource is the same datatable. I need the
first one to show only 2 columns, the second to show 99 columns.
They also have to be in sync - if I resort one, the other must also
resort. That's why I am not using dataviews. But this doesn't work.
The second grid shows 99 columns, the first shows all 108. What gives?
Please 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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
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,...
