Getting the path of an XML node in your code editor

Posted by jpluimers on 2021/05/27

A few links for my link archive, as I often edit XML files (usually with different extensions than .xml, because historic choices that software development vendors make, which makes it way harder to tell editors “yes, this too is XML).

Chocolatey, MSI installers and “… was not successful. Exit code was ‘3010’. See log for possible error messages.”

Posted by jpluimers on 2021/05/27

For some Chocolatey installations, I got an error message like this one:

"ERROR: Running ["C:\Users\Developer\AppData\Local\Temp\chocolatey\vmware-tools\10.3.10.12406962\VMware-tools-10.3.10-12406962-x86_64.exe" /S /v /qn REBOOT=R ] was not successful. Exit code was '3010'. See log for possible error messages."

I wish that a Chocolatey install could indicate it is msi based, and Chocolatey would convert this to a soft reboot message, as [WayBack] MsiExec.exe and InstMsi.exe Error Messages – Windows applications | Microsoft Docs indicates it means ERROR_SUCCESS_REBOOT_REQUIRED:

Porting old code: Delphi compiler error E2064 Left side cannot be assigned to

Posted by jpluimers on 2021/05/27

Quoting this in full because it nicely illustrated the introduction of an intermediate variable that cannot be assigned to a second time after initial setup by the with statement: [WayBack] Embarcadero Newsgroup Archive :: embarcadero.public.delphi.ide :: Re: Delphi 2010 Compile error E2064 Left side cannot be assigned to.

This is no bug, because the parenthesis generates an intermediate
non-addressable value and D2010 does not longer allow write access to intermediate values with “with”.

This also might explain Delphi 10.2 Tokyo introduced a “with” warning: for most “with” statements, W1048 is raised ([RSP-17326] with statements generate W1048 unsafe typecast warning – Embarcadero Technologies), assuming that the intermediate is a pointer variable.
