Querying serial ports device information. Getting "unfriendly " identifier


I want to fill a list box with the "friendly" names for the serial ports
installed on a system, yet I also need to query the names required to
connect to that port.
ie I enumerate the friendly names of the Ports using the
SetupDiGetDevic eRegistryProper ty api call passing SPDRP_FRIENDLYN AME to get
the friendly name "Prolific USB-to-Serial Comm Port (COM3)", but I also need
to know how to get the "COM3" part on its own.
I tried changing the SPDRP_FRIENDLYN AME to several other possible
parameters available to that api call but didn't get "COM3" from any of
them.

SetupDiGetDevic eRegistryProper ty(NewDeviceInf oSet,
DeviceInfoData,
SPDRP_FRIENDLYN AME,
0,
DeviceName,
MAX_DEV_LEN,
IntPtr.Zero) )

I was just thinking about this, specifically wondering if there's any features that the C specification currently lacks, and which may be included in some future standardization. Of course, I speak only of features in the spirit of C; something like object-orientation, though a nice feature, does not belong in C. Something like being able to #define a #define would be very handy, though, e.g: #define DECLARE_FOO(bar) #define...

Hi I have a few combo boxes where the match is required. When I select a value and then delete it and go to another control then I get very user unfriendly message "invalid property value". I want to allow to go to a different controls if the value is empty and if the value is not in a drop down box I want to either display a user friendly msgbox or clear the drop down box value. Many thanks in advance

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...

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,...
