I have an event handler in a subclass of TreeView:
protected override void OnMouseUp(Syste m.Windows.Forms .MouseEventArgs e)
{
if (e.Button == System.Windows. Forms.MouseButt ons.Right)
this.contextMen u.Show(this, new System.Drawing. Point(e.X, e.Y));
base.OnMouseUp( e);
}
When I right click, the menu pops up. If I left click somewhere outside the
menu, the menu disappears, but thereafter every LEFT click causes the event
to be fired again with e.Button == System.Windows. Forms.MouseButt ons.RIGHT.
It works correctly in the list view.
Any suggestions as to what could be causing this and how to fix it?
Thanks,
Aaron Queenan. 2 1738
If the first left click is over an item, the problem occurs. If the first
left click is over the control background, the problem doesn't occur.

Sorry, I should have said (if the first left click is over an item's
CHECKBOX). The treeview and listview I am using both have checkboxes
visible.
Thanks,
Aaron.

In the code snippet below, I tried to allow the user to choose a page to
view by selecting an item from a dropdown list. I could make it work on
Mozilla and related browsers, but I couldn't make it work on Internet
Explorer. It *seems* that on IE, when the user highlights an item on a
dropdown list and then let go of the mouse button, no onmouseup event is
generated.
Can somebody tell me what the problem was?

I am trying to let the user drag a rectangle over an image, which will

something wrong in implementing the onmousedown and onmouseup events.
Everything is very simple so far. I just defined an onMouseDown event to
record the event's x and y locations as the starting point, and an
onMouseUp event to record the x and y of the end point, and this function

I am a complete Javscript newbie trying to produce a user interface
similar to Google Maps -- the user should be able to click anywhere on

The Javascript works OK when the map is only dragged a few pixels. If

Hello,
I'm trying to experiment with some javascript to do some custom
dragdrop handling. I wish to use the onMouseDown event to trigger the
start of my drag, and onMouseup for a potentential drop. I hope to
turn on the onmouseup only in onmousedown. And eventually go one step
further and incorporate onmousemove for a true drag workflow.
I'm running into a problem however, where after mousedown, mouseup will
not fire when I release...

I am flummoxed, I'm relatively new to javascript and I can't get my
onmousedown onmouseup script to work.
simply, I want to fire one function when I click down on a graphic and
a second when I release.
I tried different combinations of onmousedown onmouseup and onclick
and putting them in div's img's and anchor's but I can't get it to
work, any ideas?

In Firefox, if I click in the black box and then release, I get a
popup. If I click, drag the cursor, and then release, I don't.
Similarly, if I click and then release outside of the black box, I
don't get a popup, and I don't understand why.
If I comment out "document.getElemenById("demo").onmousedown =
mousedown;", it works. Why would that make a difference?

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,...
