I have a lot of respect for David Fenton and Allen Browne, but I don't
understand why people who know how to write code to completely replace
a front end do not write something that will automate the code that
implements managing unbound controls on forms given the superior
performance of unbound controls in a client/server environment. I can
easily understand a newbie using bound controls or someone with a
tight deadline. I guess I need...

Hi,
Both the methods below open up a windows form called MasterForm. However, one works better than the other. Method 1 opens the form correctly but I don't have any reference to the instance of master form. Method 2 opens the form but when I right click on the Notify Icon I don't get the context menu that I should be seeing. I can interact with the main form window but I cannot interact with the NotifyIcon. Method 2 gives a object reference...

I have been converting a program from VB6 to VB.Net and enhancing it as
well. All has been progressing OK although its been hard work. Now, all of
a sudden, when I try to execute a ShowDialog() on one of my forms I get "An
unhandled exception of type 'System.ExecutionEngineException' occurred in
system.windows.forms.dll".
I can't work out what has caused this, and can't find any help on the
Microsoft site or anywhere else on the web. ...

I have the following situation:
Need a user resizable user control. After much trying with user control I
came across the idea of hosting the controls in a form marked as not
TopLevel = false. This work fine for most cases, allowing the user to
resize the form (and controls within the form.
The forms them selves are create dynamically when the user drags a node from
a listview to a panel (contained in a Usercontrol which is hosted by...

Hi,
I have a periodic problem which I am having a real time trying to sort.
Background:
An MDI VB app with a DB on SQL 2000.
I have wrapped all the DB access into an object which spawns a thread to
access the database and then displays a modal dialog which allows the user
to cancel the task, if it is taking longer than they want, and shows them a
display of how long the query has been running so far.

inherited form I get all sorts of problems. e.g. I sometimes get

declared, when I change it to public and then back again to private the error
goes away!!!
Also I get lots of member not found errors, these however don't stop me from...

In my application I have a form (Customer) that I want to be able to open
multiple copies at once. Within this form I have other forms that can be
opened. Example: ZipCode. When the user enters a zipcode that is unknown
this form will open. I don't want users to modify any of this customers

Most computers default to English, but sometimes we require a different language, especially when relocating. Forgot to request a specific language before your computer shipped? No problem! You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it.

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,...

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...

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...
