That is one reason I quit using MS custom controls, you
have to buy the license. In VB 6 they give you a try it
license and then you develop a huge application or small
one and find out you don't have rights to use the
control. You have to contact the manufacturer of the
control--MS may not be the manufacturer, in the original
VB 6 docs it told you who to contact. Then you must pay
them what they are asking, some are a one time fee and...

Hi
I am developing an app in which I have used a MSComm object. I have opened
the
port, performed the transactions, and then closed the port.
But when I check in the task mamager, the memory being held by the MSComm is
not being released. I am using the SetPortOpen method.
Is there any way of releasing this memory explicitly.
Regards.

I am using an activex control mscomm to control a serial
port in VB.NET. I place the control on the main form and
set its port, baud rate, etc. properties. After creating
a code module that needs to access the serial port, I
cannot seem to be able to access the mscomm control from
within a code module. In VB6 you could use the statement
frmMain.Mscomm1.output = "some data string" in the code
module but this won't work in VB.NET. Does...

Hi
I'm trying to open a vb6 project in vb.net which uses the mscomm component.
When running the vb upgrade wizard in vb.net, an error is raised:
Upgrade failed, unable to load reerenced component
mscomm32.ocx (1.1.0)
You need to install this component before you upgrade the project.
Does anyone know how to install the mscomm component.

I get the following error message when I output to the mscomm:
An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in COM.exe
Additional information: Exception from HRESULT: 0x800A1F52.
No one has been able to tell me why this isn't working. I know VB 2003 doesn't have serial control however I need to send this with the mscomm.
It will break at the line : comm1.Output = Packet(i)

Hello,
I'm encountering a "Blue Screen of Death" when I try to send data to a bluetooth sensor via a serial port, using the MSCOMM ActiveX object. I was wondering if anyone has any ideas how to fix the problem.
As some background, I am trying to use VB to communicate with a Wi-Tilt bluetooth accelerometer, a sensor which sends data over a COM serial port. I have no problem talking to the device in Hyperterminal; it streams data into...

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...

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...
