    My perspective is from the VCL app where any number of frames and forms can have focus.

    For your scenario reading the COM port is a better solution. We have only one form that displays many details related to scanned bar-code. Usually the user will work all the day only with a bar-code scanner. No keyboard, no mouse. And the installation must be as easy as possible. Some want to work on Linux, others on smart TV Box's with Android... so this year we moved this part in browser.

    or the scanner presents as a virtual keyboard (wedge configuration). The latter is something that we avoid.

    A little off-topic but this depends. I prefer the scanner to be a keyboard because every client want to user their scanner and setup is very easy. Just plug the scanner into USB and is working.

    With VCL I use Form.OnKeyDown with Form.KeyPreview=True.

    Even in browser I use document.addEventListener("keydown", WAKeyDown). This way if the web app tab in the browser has focus I receive the input from the keyboard. No need to have a edit box in focus.

    And reading a serial port in Javascript is not so straightforward.

    But there can be a issue if you want to distinguish between a real keyboard and barcode reader.

    table1:=Tslim.Create

    You told as that a component is becoming nil. Nil can be a reference to an instance of a class (namely a variable), not a class itself.

    If table1 is that component that is becoming nil then put a data breakpoint on table1. More exactly on table1's address (namely @table1). But it is enough to write table1 into the addresses field of "Add Data Breakpoint" dialog.

     

    @Remy Lebeau thank you very match for this. I needed a data breakpoint sometimes but I didn't know they actually exists.

    Nobody likes that we do work in one folder and git is constantly shuffling around files in other folders, and throwing up conflicts because someone else is in the middle of doing some work that has nothing to do with what you're working on. Branches only seem to make things worse. When I do a branch, I only want to focus on a given folder.

    In this case I think it would be better to have all that folders in one repo. Then a branch would not be disturbed because all is there.

    You will have to deal with conflicts only at merge.

    I never needed forums to solve my problems... I could find all the answers on SO and official documentation. 

    If you are not in the first wagon then yes, others ask for you. :classic_laugh:

     

    I just setup a SSH and Git as server on Windows using OpenSSH that comes with Windows 10 but this came only two or three years ago and information is not yet well polished. Git as a server on Windows is also not so frequently used.

    It was enough the information I found, I did not need to ask for help, but it was harder than I thought. Now I think that doing the same thing on Linux is easier because almost all info is for Linux.

    Installing Subversion server on Windows was a piece of cake some years ago.

    D10.4 with i7-8700K

    For me anywhere in the source IDE CPU is 10% and very responsive.

    At the bottom when white space appears is 25% and a little slower but not an big issue. I rarely use scrolling when bottom white space is shown.

    I think this issues is tied to CPU speed + Number of LOC displayed when bottom white space is shown. No graphic card involved.
     

    Try to make the IDE height smaller in order to display fewer lines of code and for sure it will be faster and.... useless.

    Does it behaves better on host? I think does not.

    I have almost the same configuration and bellow settings for display but I don't see any issues with scrolling. In VM is Windows 1903, on host 2004.

    I don't do any adjustments to the IDE after instalation.

    I will try to install Windows 2004 also in one VM and see.

    Update: I can install now Windows 2004 only on older VM's, on newer VM's with D10.3.3 and 10.4 I have this message "The Windows 10 May 2020 Update is on its way. Once it’s ready for your device, you’ll see the update available on this page."

    Then it looks like it's deallocated at close. Maybe if you can debug and look in task manager. Put a break point in System._Halt0 and maybe you will see where is deallocated.

    Maybe deallocation is in finalization sections or some dll's.

    Maybe this MemoryUsed function can be called from watch list and compared with Task manager.

    When the error is caught, cursor stays in the same cell, but wrong value displayed across all records

     

    I can't reproduce this issue (the wrong value to be displayed across all records). What Delphi version do you use?

    Try to do a minimal example to reproduce this and post here.

    I modified your code slightly

    But why ?!? Your code is more convoluted and I don't see any benefit. Only trouble.
