Hi,
I have a validating event on a textbox in which I want to prevent the user
to leave the textbox without entering the right data. Only if he clicks on
another specific control he is allowed to leave the textbox without entering
the right information. Is there a way to determine which other control was
clicked in the validating event of the textbox?
Thanks

Hi
For a while now I have been finding postings of problems with the
validating event not firing on controls properly. I too had this
problem. The event would fire when clicking on another control which
had it's causes validation property set to true however if I tabbed on
to this control the event wouldn't fire. So after playing around with
my code I figured out how to get it to work. I am not sure what the
reason behind it is but it...

I am experiencing some strange behavior between a UserControl's validating event and a treeview control. Initially, I thought it was related to an issue in the Knowledgebase article 810852 (http://support.microsoft.com/kb/810852), but then I realized that the hotfix mentioned was in .Net v1.1, which I am using.
I took the sample from that article and recreated the situation I see in my application. (Code included below.)

Is there an easy way for me to validate what's entered in a webForm
textbox? For example, how can I check that the user only enters a
number (and not letters) in a textbox?
I have VS 2005.

Hi there,
Is there a general approach for preventing users from selecting a menu item
in an SDI or MDI application whenever the current field on your form is
invalid (assuuming the app consists of a data entry form). In my case, I'm
working with a "DataGridView" which occupies the entire child window of an
MDI app but the problem likely applies to any control. If you've entered
invalid data into a "TextBox" field of a form for instance...

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
