People say that is a bad technique to throw exception from
constructors; and that the solution would be to create a function
_create_ to initialize an object.
What about copy constructors? How can we avoid throwing exceptions? If
we already have an abject witch was initialized wit _create_ we will be
forced to call create in copy constructor and to throw exceptions from
it.
Have a nice day,

I have an unbound form with a textbox with an input mask 00\-00000;;_
Putting some data into the text box and then trying to close it throws the 'didnt match input mask' warning, and if
I click ok on that it brings up an error:
"You can't save this record at this time." ..."data changes will be
lost...want to close...anyway?"
It doesn't give me an error number, and I don't have any records to
save.
What can I do to capture this error?

Can't compile. Does this mean that all functions that throw exceptions
must be of return type void?
examples:
// won't compile: "not all code paths return a value"
public override int Run() {
throw new Exception("exception thrown");
}

Hi ,
I would like to throw a error/warning message to the user based on the Inputs given.
Case 1) If the inputs are not given correctly.I have to diplaythe message,saying "Enter the correct inputs"
Case 2) In between the functions,if I am getting a wrong input data ,I have to stop further execution of the application and display the error message " Calculated xyz values are wrong ..."
I hope we have to use "try " and "catch' blocks.

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,...
