Finding your program with an “Access Denied” (Error code 5) after lunch break…

Posted by jpluimers on 2018/10/24

Via: [WayBack] I just returned from lunch break and found my program faulted with an “Access Denied” (Error code 5) error in a call to Mouse.GetCoursorPos and was wond… – Thomas Mueller (dummzeuch) – Google+:

All of [WayBackGetCursorPos, [WayBackGetCursorInfo and [WayBack] GetKeyState can cause an “Access Denied” (Error code 5) when they do not have permission for the current desktop (for instance the logon desktop when a screen-saver has kicked in).

Solution: write a wrapper around it then [WayBack] patch calls going to the original into the patch [WayBack] delphi – Explain errors from GetKeyState / GetCursorPos – Stack Overflow

Delphi: uninstalling the ancient CollabNet 1.7.5 version

Posted by jpluimers on 2018/10/24

Somehow the integration team at Embarcadero still hasn’t discovered there are [WayBack] newer CollabNet SVN Client versions than 1.7.5 which has been shipped since Delphi XE3 until Delphi XE6. The newer version (currently 1.8.8 when writing this, now 1.10.2 in 2018) have plenty [WayBack1/WayBack2SVN security issues fixed.

The easiest way to uninstall the CollabNet SVN Client is running this small script:

call :start %ProgramFiles%
call :start %ProgramFiles(x86)%
goto :end
set CollabNet="%*\CollabNet\uninst.exe"
echo %CollabNet%
if exist %CollabNet% start "CollabNet uninstall" %CollabNet%
goto :end

Then install the [WayBackSlik SVN client. Like [WayBackЈοеу, I’ve switched to [WayBackSlik SVN a long ago. Here is [WayBackhis reasoning:

I have long since stopped using the CollabNet-branded version because it’s behind a registration wall. I found Slik SVN as a good alternative. It’s exactly the same command-line client you get from CollabNet, sans the hassle in downloading it.

I hope someone at Embarcadero enters this in QC^w QualityPortal as I’m awaiting Embarcadero response about a security issue there.
