Hi,
I have an application that has (for the sake of argument) 2 (MDI) windows
open.
If I click into a textbox on FormA then the 'Enter' event for that TextBox
fires, great!
However, if I then click on FormB, then back to FormA although the cursor is
still flashing in the same textbox on FormA, when I tab out, the 'Leave'
event for that TextBox does not fire. If I stay on FormA and Shift-Tab back
into the textbox then the 'Enter' event...

After a user enters data into a field, I need to populate other controls on
the form, based on the user entry. I have to use either Leave, Validating or
Validated, and I take it I can't use LostFocus because there is no selection
for that event in the dropdown list on the code page. What's happening is
that all 3 events mentioned above for the textbox control fire in the proper
order when the form is invoked, but don't fire the first time...

Hi
I have three textboxes indicating the individual RGB values of a
color. When the user leaves a textbox (Leave event), I check the
validity of that number and saves the three values to a set of raw

uses the 'sender' variable...

Hi,
I have a form with many textbox on it. Behind this(so to speak), is a class,
and each time the user changes the value of the text box I want to update
the relevant property of the class.
I have the class.property = txtbox.text set on the textbox.leave event, and
this works fine, except for when the user clicks on my toolbar button to
save the details to the database.

Hi,
I have a problem with my textchanged and leave events
I have a script in the leave event of my textbox and also in my textchanged.
The script in my textchanged adds and displays a tabpage.
By this action, automatically, the leave event executes its scripts
and this is my problem.
How can I remove or disable the Leave Event Script when I m in the
textchanged. I suppose it's when the tabpage is added.

Hi,
I just installed VS.Net 2003 and upgraded my project to 2003. Immediately
found the following new behavior which causes my solution working erratic.
In the leave event of a control (e.g. TextBox) I select (set focus to)
another control cause the leave event to raises again of the source text
box.
Steps to reproduce.

I have code (using the leave event) in a textbox which prevents the user
from leaving the box if it is blank. I would like the user to be able to
click on the button of the form and close that form without firing
the leave event in that text box. An answer would be helpful.
Thanks,
Bill

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...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
