Is there any way of simply using the COM port from Visual Basic? All the
solutions I've found seem to require the use of Visual Studio whereas I only
have the the 'basic' version. I'm not after anything too complicated as all I
want to do is read a serial stream of data.
Thanks in advance

Hello Oh ye Gods of .Net,
I'm going to finally upgrade from VB(5) to NET. I
havent written in much of anything else than Visual
Basic. Will I need to buy Visual Studio or can I get by
with Visual Basic Standard for applications that send and
recieve with the serial ports? I'm using a PC to talk to
industrial equipment.
thanks for reading,

I have a fairly large heritage VB 6 application that controlsabout 5 serial port devices with a fairly complicated but lineartimer scheme to service all of them (a work around of the singlethread aspect). I am trying to upgrade incrementally, and wantto write a VB.net stand alone class / module / application thatcan service one of these devices on it's own. I'd start thisapplication from the VB6 heritage program and (ideally) serviceinterrupts...

Hi,
For my windows application I'm using OpenNetCF's serialport stuff but I'm
having a small problem.
In my program I want to list a range of available ports to select.
This works fine for the first 16 ports, but not for the higher ports.
I do this as folowed:
For ab = 1 To 32

I need help using the serial port under VB.NET. I found a control called
AxMSComm which I assume is the comm control, but there's no
documentation in my MSDN help. Where can I find descriptions of the
methods and properties of this control? And why doesn't MSDN have it?
Thanks

I am trying to receive GPS data into a pocket PC 5.0. I am using the
device emulator. The main PC has a bluetooth dongle connected and is
bonded with the bluetooth GPS transmitter to COM8. In the device
emulator, I am mapping Serial Port 1 to COM8. The below code *should*
work as far as I can see but it does not. It hangs on the ReadLine
line. Any ideas anyone?
If I use hyperterminal on the main computer to read COM8 I can see the...

Hi,
Hopefully this is a pretty basic question. I need to perform serial IO using
VB.Net (VS2005/Framework 2.0) but the devices I communicate with can be
either RS-232 or 422/485. Is this a concern to me as the programmer, i.e.
does the UART or whatever handles the electrical side of things or do I need
to be aware of the type of connection being made a program accordingly. I
know I need to use System.IO.Ports.SerialPort but does this...

I have an application that interfaces with a USB device using the .Net
serial port. The code works fine, displaying live data on the screen;
that is until the USB lead is pulled out from the PC when the program
hangs.
The obvious answer is not to pull the lead out, but unfortunately the
application is one in which there is a high possibility the lead will
be pulled out so the code needs to be more robust.
The form has a timer...

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...
