Is there any way to get the modal Search and IDE Insight back? – via G+

Posted by jpluimers on 2016/07/28

I’ve quotes two of the G+ comments as they perfectly reflect my point of view: the non-modal search and IDE Insight – introduced somewhere after XE3 – are a dork to use.

I’m doing more Delphi work lately and these being non-modal seriously hinder my work (and it gets progressively worse on a 3K or 4K monitor).

In my book: why implement a feature to emulate the competition when you do it so badly?

So: are there any experts around that bring back the old search and IDE Insight behaviour back?

Asbjørn Heid, Oct 5, 2015: 

+Marco Cantù I’m pretty sure I’ve mentioned it before, but hey:

  • The new edit field cannot be placed in a position which does not require significant eye-focus change to read. This means it is significantly more cumbersome to use, as focus must be transferred to some “out of sight” area. In addition one does not get the same instant feedback that the IDE did register your F6 keypress. The old one was “in your face” instantly when you pressed F6, so no need to take your eyes off the form you’re designing, and it left no doubt about F6 being registered or not.
  • The dropdown list with suggestions that pops up when you type is much more difficult to read than the list in the old one, both due to positioning (thanks to the above) and due to length until it’s heavily constrained by input.
  • From what I recall, the new edit field does not behave the same when invoked repeatedly, requiring more keystrokes to get the same effect compared to the old. I haven’t used XE3 in ages though so I don’t recall the specifics anymore, just that the new feels more clunky to use.

That’s just off the top of my head. Yes I still use it, but not nearly as much as I did, and when I do it’s one to two orders of magnitude slower to use compared to the old one. Not because it searches slower, but because of the issues described above.

David Heffernan, Oct 5, 2015: 

+Marco Cantù I second what +Asbjørn Heid  said. When I press F6 now, I never know where to put my eyes. In XE3 a dialog popped up which took my attention.

Similarly for the non-modal search, although somehow I’m more used to the modern version now.  When compared with VS though the Delphi search is very lacking. The great thing about the VS search is that it gives live feedback on which text in the edit window match the text in the search window. If Delphi would do that it would make an immense difference. It’s definitely worth spending some time in VS using their search facility. And indeed in other IDEs / editors.

There was a lot of negative feedback on both of these changes when they were released. Surely Embarcadero noticed that.

In hindsight, what they should have done when ZEROBASEDSTRINGS were introduced (yes, Delphi XE4):

Canonical overview on Writing to the Windows Event Log using Delphi – Stack Overflow

Posted by jpluimers on 2016/07/26

A while ago, StackOverflow user Kobus Smit did some brilliant editorial work that – due to current state of StackOverflow – sort of fired backwards: his question got marked as duplicate before he could post his excellent answer. After that answer was posted, the oh-so pride SO-demi gods never took any energy to revisit to see which answers were best.

His simple question:

How can my Delphi app easily write to the Windows Event Log?What is the difference between TEventLogger and ReportEvent? How do I use the ReportEvent function?

Which somehow should be encompassed by this Delphi 5 question (apparently that 15+ year old Delphi version is still considered current by the SO demi-gods).

The answer summarises and extends existing answers spread out over StackOverflow and adds an EventLog git repository wrapping the ReportEvent and RegisterEventSource (which somehow is always a pain: Delphi services for instance often forget that).

Lesson learned when doing editorial work:

  1. prepare both the answer and question in markdown off-line
  2. ensure you mention in the question that the answer is meant as collection of “best of” answers found elsewhere
  3. post the question and answer in rapid succession
  4. cross your fingers for the StackOverflow demi-gods being in a good mood

delphi – Building Multi threaded TCP/IP Server – Stack Overflow

Posted by jpluimers on 2016/07/21

On the research list: TIdSchedulerOfThreadPool (now that TIdThreadMgrPool is gone).

Need to manage the lifetime of these as I don’t want the threads to live forever, but also don’t want to make the instantiation cost too high.

Most likely I want to wait for them to finish as well upon process exit, so this might be worth a look as well:

Delphi packages I have disabled by prefixing their description with an underscore (and why)

Posted by jpluimers on 2016/07/19

There is a little trick to disable “Known IDE Packages”: you can stop Delphi from loading one by either making “Value data” of the registry blank, or prepending it with an underscore:

packages that might have been disabled, by checking any string entries where the data has been pre-pended with an underscore OR is blank

Source: Access violation at address 00000000 read of address 00000000, when starting the IDE or opening a project after installing the updates

I’ve pre-pended underscores to some packages in the registry key [HKEY_CURRENT_USER\Software\Borland|Codegear|Embarcadero\BDS|Delphi\#.0\Known IDE Packages] and intend to keep the list below updated over time:

  • _Start Page IDE Package
  • _Castalia
    • It
      • interferes with the clipboard which means Ctrl-R / Ctrl-P macro recording/playback will often find an empty clipboard when pasting
      • often causes out of memory errors and other bugs
      • takes over keyboard actions interfering with my edit habits
        • (like re-assigning the slash key when you have a character on a line selected making it a block: bye-bye replacing just one character with a slash now; we’ve always had Ctrl-Slash to commend out a line or block)
    • Note you
      • have to *also* disabled it in [HKEY_CURRENT_USER\Software\Embarcadero\BDS|Delphi\#.0\Known IDE Packages\Delphi]:
      • can disable (without changing the regsitry at all) it by appending " /NOCASTALIA" (without quotes but with leading space) to the parameters of the Delphi shortcut (another little Delphi secret).
