Especially important for Delphi users on Windows 10 Creators Update: IDE Fix Pack 6.1 released | Andy’s Blog and Tools

Posted by jpluimers on 2017/10/31

The new [Archive.isIDE Fix Pack 6.1 released | Andy’s Blog and Tools is huge, especially for Windows 10 targets:

Windows 10 Creators Update 1703 caused issues with all Delphi programs, libraries and packages because it changed how Windows loads imported DLLs in such a way that it causes performance issues and can crash the debugger.

Delphi 10.2 Tokyo Update 2 fixed this by not producing multiple dll import sections for one DLL anymore.

IDE Fix Pack 6.1 implements that “feature” for all previous Delphi versions (2009-10.1 Berlin) and extends it to not only eliminate duplicate dll imports but also duplicate delay dll imports.

There are also (optional) updates that you can enable with new compiler switches:

  • Eliminating fwait instructions (but be careful, as they can confuse the debugger)
  • Optimising calls to virtual methods through interfaces
  • Optimising certain function prolog code

There are some smaller changes too.

I’m going to try this soon.

Firebird – generate time/date/timestamp values

Posted by jpluimers on 2017/10/31

I needed the script in [WayBackFirebird – generate time/date/timestamp values to reproduce a problem in Database Workbench <= 5.3.2 with exporting TIME and TIMESTAMP values to Excel xlsx format: the time portion got lost so

The bug is fixed so will appear in the next beta and release versions: [WayBack] 0001506: Timestamp export to Excel XLSX only shows date, Time fails, CSV shows both date and time – Bug & Feature Tracker @

Until someone writes proper string visualisers for the Delphi debugger…

Posted by jpluimers on 2017/10/31

A few tricks to write long strings to files when the Delphi debugger cuts them off (just because they like using 4k buffers internally);

  • TStringStream.Create(lRequestMessage).SaveToFile('c:\temp\temp.txt')
  • TIniFile.Create('c:\a.txt').WriteString('a','a',BigStringVar)
  • TFileStream.Create('c:\a.txt', fmCreate or fmShareDenyNone).WriteBuffer(Pointer(TEncoding.UTF8.GetBytes(BigStringVar))^,Length(TEncoding.UTF8.GetBytes(BigStringVar)))

They all work form the debug inspector, but they do leak memory. See comments below.

Android app writers: How to lose your end-users’ notification privilege…

Posted by jpluimers on 2017/10/30

Android apps make sounds when posting notifications. So adding useless gets you on the blacklist quickly thereby disallowing your app for posting any notifications at all.

Kristian shows how and why at

How to lose notification privilege:

  1. Use notification for marketing.
  2. Long press.
  3. Disable.

It’s that easy. You never force grab my attention for marketing a second time, especially since Android notifications by default come with sound now. This one woke me up.
