OK this has me perplexed, puzzled and bamboozled!
I have a remoting service which I displayed a message box in. I then
wondered what would happen if a client made a call to the service
while the message box was being displayed. Since the call comes in on
a different thread the client call was not blocked. This seemed to
make sense to me.
Next I thought, what will happen when the client calls into the server
if I try to use a delegate...

I get a Null Reference Exception if I close a non-modal dialog (that is, a
form opened with Show()) when a selection is made from a ComboBox. The error
message refers to Unsafe Native Methods, but the code is 100% managed. The
exception is not thrown if the dialog was modal (opened with ShowDialog()) or
if the selection is made from, say, a ListBox.
I have included a simple example below.
I am using C#.NET 2003, Standard Edition.

I have a frameset aspx page that enables users to upload photos. One
frame/page shows a thumbnail list of prevously-uploaded images, and the
other frame/page includes the controls that enable selecting and uploading
additional photos. After uploading a file, the list of thumbnail images

I have got a problem while using the modal dialogs. In my code I need
to open a modal dialog from the parent page and I need to enter some
values in the dialog and save it. It takes the values properly and also
does the validation of the values but it doesn't hit the event handler
of the button where it is supposed to save those values and close the
box.
Any help is appreciated.
Thanks

secondary form i need to open a Modal Window in such a way that, my
secondary form is blocked, but i can still access my main forms, and

I have created many shortcut/popup (aka context, or right-click) menus for my
application - instead of toolbars or standard drop-down menus.
Within my custom menu, I am using =ShowMainMenu("item") in the On Action
event where ShowMainMenu is a public function in frmMain, and "item" is a
string mapping to a button click event.

Hi all,
I am working on a windows based client server application with
multiple forms. All forms are having custom title bars with no default
bars. There is one main form. Some forms are opened up as modal while
others are opened up as modeless on this main form.
Whenever some error occurs in client server communication we show it
in modal message box.
Now I ran into a case: a modal form is opened up on the main form.
And some error...

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:

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,...
