I can generate this error by NOT assigning a tableName to the view:
at System.Windows.Forms.DataGrid.AddNewRow()
at System.Windows.Forms.DataGridAddNewRow.OnEdit()
Is there any possibility of getting an event from the AddNewRow()? I
would like to make some changes to the row prior to the user typing in
the DataGrid.
Thanks,

I've just released an article on using Test Driven Development with C# and
Windows Forms. GUI's are often difficult to test, so I thought it might be
of interest.
The article along with the example source code can be downloaded here:

Ok, I'm a little rusty on this, it should be a simple problem but I
can't figure it out. How can I handle form events in my main code
page??
I'm creating a Windows App in C#. Rather than make my main form the
startup object, I'd rather put my Main() function in a class or code
file. Why? Because thats what I always do in standard C++ or VB. In
my opinion, writing all my application logic in the form itself is
sloppy and only for...

Is there any way to know whether the OnItemCheck is being called in response
to a user action (mouse or keyboard) as opposed to the form loading?
I have a class which derives from System.Windows.Forms.ListView. Among
other features, it enables the checkboxes and overrides the OnItemCheck()
method. I have placed this ListView on a form and use form.ShowDialog() to
display it whenever the user presses a certain button.
If the user...

Hello,
I am trying to find a way to tell if an .NET windows forms Button
(System.Windows.Forms.Button) is "depressed" (pushed down). For my
application, I can not use a check box control set to button style, I
must use a System.Windows.Forms.Button. I can not find a way to tell
when it is momentaraly pressed.
I tried calling the API SendMessage with the button handle and
BM_GETSTATE to get the state of the button. This will only return...

I am having a lot of trouble with an ascx page that has a textbox that

I would like to do some client side stuff whenever my page is posting
back. My page has a lot of different buttons and links that will cause
a postback. I would rather not have to put something in each of their
"onclick" functions. I would rather have a global OnPostback function
or something like that. I tried using the form's onsubmit function,
but it only gets called when my buttons are clicked; it doesn't get
called when a link gets...

Hi All
VS 2008 Pro
It appears that the form_closing event of a form may not always fire. I put
an explicit lock on a customer record when it is open for edit and then
remove the lock in the form_closing event when the form is closed. This used
to work fine in VB6 but appears to be a bit unreliable in VB.Net.

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

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.
