I have an application model which will consist of a front-end
configuration application, which needs to control the state of a
back-end vb.net windows service (which is the component that does all
the work). Think of this in the same manner as say microsoft management
console and the w3svc (inetinfo) service.
What should the standard communication protocol be between the
configuration app and the service in this model?
For example,...

Hi,
I'm having trouble letting my background thread tell my main thread what to
do.
I'm trying to tell my main thread to open a form, but when my background
thread ends, the form that I thought my main thread had opened disappears.
Obviously there's something that I don't understand here.
The background thread is run in another class on another form. How do I,

Hi,
In the past I created a VB6 application that was capable of accepting
multiple client connections for status logging over the internet using
simple non-Windows clients (GSM/GPRS). There is one management
console/monitor that receives messages and keeps track of keep-alive
polling. The monitor created a new WinSock connection for each client that
logged on. These were put into an array of controls. I'm sure this can also
be done with...

Hi all,
I'm using a FileSystemWatcher to monitor a directory. I want the FSW
to pop up my already instantiated but invisible form.
However, I'm running into some problems with this.
1) In the FSW.Changed FileSystemEventhandler, I called the Show method
'frmMain.Show( )' on my form, the form appears but not completely
painted and it appears to be hanging with the hourglass.

Hi All,
I have a VB.NET application that constantly executes queries through
ODBC connections. The application consists of a simple Form type UI
where the query parameters can be edited, and a simple scheduler that
executes the queries.
The application works fine as "standalone" but it now needs to be
installed on a server and left running permanently even when no user
is logged on.
I think a Windows Service would be perfect for 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:

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...
