Hello,
Say I create a class ("Child") that inherits from another class
("Parent"). Parent's destructor is not virtual. Is there a way I can
prevent Parent's destructor from being called when a Child object goes
out of scope?
Specifically, I am dealing with a C library that provides a function
that must be called to "destruct" a particular struct (this struct is
dynamically allocated by another provided function). To avoid memory

I have a form which the user must complete before closing. I have
disabled the window x button and use my own exit button. When selected
it checks to see if the user has completed the entries otherwise it
cancels the close.
However, the user can still right click on the task bar and close my
application.
Is there any way of preventing this.
Thanks
Alex

Hi. I have a class derived from a UserControl,
that I want to allow others to derive controls
from. I don't want them to design the base
class (which is derived from a UserControl).
I know that I can prevent the control from being
designed by making it not the first class in the
code file, but is there another more 'official' way
to do this via attributes.

I am faced with the following problem: I have a page (let’s call this page page1.aspx) containing some TextBoxes and a hyperlink which opens another page (let’s call this page page2.aspx) as a popup using either window.open or window.showModalDialog. Since I want to warn the users of my application when they try to close page1.aspx and have changed the values in the meantime I thought about using the “onbeforeunload” event of the...

On a multi-textbox form, linked to an external js, I use onBlur to call:

I have some users that continuously end task on my database when a search
takes to long. In turn corrupting the application. Is there any way to
prevent this? The Microsoft KB for Methods That Can Be Used to Prevent
Corruption suggests not allowing Task Manager to shut down the application
but gives no way to prevent this. Any suggestions would help.
Thanks in advance,

Hi all.
I have a problem in my website in trying to prevent a user from double submitting the form.

When my client-side validation fires, and is invalid, I see the red text that displays the error message, but the problem is that something is...

Hi;
I need to create a custom textbox control which will not allow a user
to paste text from the clipboard. The user has to always type the text
into the textbox.
I tried searching on the internet since I guessed someone would have
faced this problem before but of no avail. Do we have pointers on how
I should go about doing this??

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:

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
