"Broadcast Message"?
Does that translate to a Windows Message?
If so, override WndProc in your Form and pick out the relevant Message.

Handling Windows Messages is done totally different in VB.Net.
Pop this into your Form code:

Protected Overrides Sub WndProc(ByRef m As Message)

Const WM_ACTIVATEAPP as Integer = &H1C

Select Case m.Msg
Case WM_ACTIVATEAPP

' Switch from another Application

End Select

' Very, *very* important bit!!
MyBase.WndProc( m)

End Sub

Hi all, about 2 years ago I wrote a small utility that was used to send and receive SMS messages via a mobile phone (3rd party COM object as used as interface). I now have to write another program that does pretty much the same thing. My old program simply sent and received SMS messages via a Nokia phone connected to the computer running the utility. I now have to write the same type program and instead of using a cellphone connected...

I have 2 projects - 1 Winform project that sends Udp messages using the UdpClient class when a button is clicked, and a Console application that listens for these Udp messages. If I try to use the UdpClient class to receive, it never works. The messages are never received (no exceptions). If I use a normal socket configured to listen for Udp messages, it works perfectly. Below is my sample code. It is only test code - I know the...

Please take a look at the simple code segment below and advise me what is wrong. According to the help and examples I've seen it should work unless I misunderstand something. The problem is that UdpClient.Receive method always throws following exception, even though I verified that message was successfuly received by devices and responses were sent back:

I'm going around in circles here and need some help. Scenario: I am using (have used) either the UDPClient class or Sockets class to broadcast some bytes to 255.255.255.255 (udp protocol). Upon doing so, a device (of which I will know nothing about) will receive my broadcast and send out a broadcast of its own. Using Ethereal (LAN packet sniffer), I can see my broadcast, and I can see the device broadcast. I cannot however receive...

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,...
