No, I cannot help you with using MSCOMM.
MSCOMM worked well in time of Win16.

But then in a real world beginning of Win32 it just sucks. :(

then it's time to learn the modern technologies! ;)

Are you also new to coding in VB6?
And why not using VB.Net or C#?

Why do you need it?

These article/discussions may be useful:

If you "need to show the icon 32x32" then do
m_imglist.Create(32, 32, ILC_COLOR32,1, 1);
...
::LoadImage(AfxGetResourceHandle(), MAKEINTRESOURCE(IDI_UnCheck_ICO),
IMAGE_ICON, 32, 32,...

You have to add a new custom (21x21) images to your icons.
Then load them using
::LoadImage(AfxGetResourceHandle(), MAKEINTRESOURCE(IDI_UnCheck_ICO),
IMAGE_ICON, 21, 21, LR_DEFAULTCOLOR));

The simplest way would be "resize" your icons (or just create the icons of the size 21x21) in the image editor. And then use these 21x21 icons.

Why do you pass 2 as the index in the image list? Your image list has the size 2, thus the only valid indexes are 0 and 1.

BTW, using SetItemImage method looks a little simpler that SetItem. ;)

Run the "programs in Debug mode" is not the same as debug the program!
Have a look at
https://docs.microsoft.com/en-us/visualstudio/debugger/debugging-absolute-beginners?view=vs-2019

Why presumably ?
didn't you debug your code to see the exact place of the "crash"? :confused:

What if you add (the block in blue)?

if (m_pResultAnalysisDialog)
{
WINDOWPLACEMENT windowPlace;
windowPlace.length = sizeof(WINDOWPLACEMENT);
BOOL bOk =...

Perhaps, this one will work?...

Very simple: you should ask your questions directly in the forum posts, not in some attachments that have to be downloaded just to read what you meant.
The same is valid for the (not too long) code...

Then you nave to implement owner or custom drawing!
some examples:
http://codexpert.ro/blog/2013/02/22/custom-draw-vs-owner-draw-controls/
https://www.codeproject.com/KB/list/#Custom+Draw

Did you try using CListCtrl::SetBkColor? Does it work or not?

std::string myString = getOwnerSerNoString();

CListCtrl already has the methods to set the background ( https://docs.microsoft.com/en-us/cpp/mfc/reference/clistctrl-class?view=msvc-160#setbkcolor ) and text colors. So you don't need to handle...

CListCtrl or CListBox?
The CTLCOLOR_LISTBOX belongs to the CListBox class (ListBox control)

[moved from Visual C++ Programming Forum]

The code you have posted has nothing to do with the native C++.
It looks like the managed code.

So I move this thread to the most appropriate Forum.

Why "exit(0)"? Why "_exit()"? :confused:
Using either of these in MFC application never was a good idea! And it is still a bad idea now!

Then have a look at the post#17

And does this code work?

Then try the option "... from registry..." (sorry, i currently do not have any VS on my notebook, therefore cannot be more precise)
