Hello,
I'm writing a small C# app, and part of what I'm trying to do
involves the dragging of PictureBox controls on a form. Unfortunately,
MouseMove seems to be behaving very oddly, causing spurious MouseMove
events when the cursor doesn't actually move. I've looked for a
solution in the groups, and although I've come close, I haven't found a
proper explanation or fix. Here is a rundown, followed by a very
simple test app that...

Hello All,
I am having a problem with events and the addition of
controls on a page I am developing. First let me tell you
what I have tried and then maybe someone can see something
I missed.
First I tried adding the controls and the event handlers
for my control in the Initialize Components method of my

Hey guys,
I am working on a web custom control that basically draws a table (ASP
Table) with a few child controls in the cells.
I have a command button inside one of these cells. The problem I am running
into is that I cannot get the click event of this object handled. I have
tried wiring the event with "AddHandler" among other things and that seems
not to work neither.

I've noticed that controls that are contained in MDI child forms fail to raise MouseLeave events if the MDI child form's MdiParent property is set to Nothing (after it was set to an existing MDI container form) or if the MDI child form's Visible property is set to False (after the MDI child form was shown). This is an enormous problem for my app because I must show different MDI child forms based on the state of my application and many of the...

I have a problem I hope you folks can help me with.
I have an application that is using a tab-based interface, with the ability
for users to drag an item from a ListBox onto the tab control. This will
create a new tab, put a new instance of the proper UserControl into the tab,
and populate said UserControl with the data culled from the drop source.
Because of the nature of this application, the particular UserControl that
will be...

I'm writing a Windows application for a client, and I've run into a problem
I don't know how to solve.
The UI is relatively simple - a listbox on the left (in a panel), and a
third-party tab control on the right (also in a panel). The usual splitter
bar, and all that good stuff. The tab control is set up to deal with
drag/drop events, so that users can drag an item from the listbox over the
tab control and have the tab control respond...

We've got a cascading delete being used in DB2. I've built new triggers under the parent/child tables in this cascading delete relationship.
So when they delete the parent, and the cascade activity occurs, I had expected that the delete trigger on the child would always fire before the delete trigger on the parent. But I was wrong! They are firing parent-first child-second!
This is causing me some concern because the sequence of the...

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,...
