Hi,
I have a usercontrol with a overridable/virtual method. On the usercontrol
onload, it will call this method.
Now I have a form that have a few of this usercontrol.
And I want to override the method in each usercontrol, how do I accomplish
this?
Thanks,
Tee

Overriding is a property of derived classes, so if you're not inheriting it,
AFAIK you can't override it. If you have access to the source of the
controls you could change them to call a delegate instead of the overridable
method, and then make that delegate settable from outside the control. It
would be a pretty nasty solution though.

Hi,
I am using a custom text box, where I need to override TabSelection, as I
have to generate an event and based on that event, I need to do some
processing in other class, who is listening to that event. This thing works
fine, when I am stopping in the debugger for the event, but as soon as I
remove the breakpoint from the event handler method. This doesn't work and
even the release version of the software also doesn't work.

However, my control has several standard controls on it, and the consumer of
my control only gets MouseMove events when the mouse is over the control

I have a usercontrol, and I am trying to write a Property called
"Text", but the compiler tells me that the Usercontrol class already
has a member called "Text". When I look (in intellisense, or help) I
don't see the member. I can easily override or make it new, but I'd
like to know what is going on.

I'm creating a web control that has an image and a text box. I would
like to then override the Visible and Text property of the
usercontrol, so when you reference the visible property of the user
control it only set the visible property of the textbox.
When i call these newly created property I get the following error:
Object reference not set to an instance of an object.
Does anybody have any idea? Thank you.

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.
