Hi
how do I validate a text value in a datagrid e.g. the user is only
allowed to type in a Y or a N. I specifically have a problem with
using the PropertyDescriptorCollection. I get the following error:
"Additional information: Cannot create a child list for field Query."
Below my existing code:

Hi y'all,
I have resized the columns in a DataGrid and I want to set the width of the
DataGrid to fit the columns. Just summing the column widths is too short
due to the grid and gray row selection column on the left.
I have the widths of the columns. What other values do I need to include in
the DataGrid width?
Thanx,

Hi,
In Datagrid, while setting width of column through GridColumnStyles
collection. width does not set to exact width that I am setting in my code.
If I set width to 13, it is changed to 130 or if set to 208, it changes to
206.
On changing width of column I am resizing the width of grid. I am using
mouse down and mouse up events for this. On Mouse down, I store the position
and on mouse up, check the difference between positions and set...

I am fairly new to VB.NET, and I am rewriting an application I wrote a while
back, also in VB.NET. I aplied some new things I learned. Anyway, here is my
problem.......

I was looking over some of my 2003 code today (see below) that loads a
foxpro table via oledb connection.
I used a sub "autosizecolumns" I found on the web but I never quite
understood why they said the style name had to be the same as the table
name. Perhaps the are refering to ts1.mappingname must be the same as
the table name (datagrid1.datamember) because I've read that that is how
the datagrid associates a style with what it's...

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...

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
