Delphi “F2039 Could not create output file” on drc files

Posted by jpluimers on 2017/01/19

I had this error when building my Delphi app and needing detailed MAP files.

Somehow, then Delphi also tries to generate .drc files and fails.

Performing the “F2039 Could not create output file” drc – Google Search didn’t reveal much.

So I fired up Process Monitor and looked for file access patterns (see dump below), that all were OK.

Then I opened Windows Explorer and saw freshly generated .DRC files marked as some type of VLC Player file. I’ve had loads of trouble with VLC in the past, but I inherited this PC so I didn’t notice VLC Player was installed by the previous developer.

Lesson learned: when starting a gig, always request a fresh PC

So I uninstalled VLC Player and now everything works fine.

Oh btw: .DRC files are Delphi Resource String files.

How good is this?

An exponential back-off implementation I used somewhere; probably room for improvement, but it works good enough.

Posted by jpluimers on 2017/01/17

I will probably need this again somewhere in the future: An exponential back-off implementation I used somewhere; probably room for improvement, but it works good enough.

It’s Delphi, but I’ve not seen practical implementations in C# either.

(the updated version thanks to Anders Melander).

function TryGetLocationLockWithExponentialBackOff: Boolean;
const
cBase = 2;
cMaxWaitMilliSeconds = 1500;
var
lWaitMilliSeconds: integer;
begin
Result := True;
lWaitMilliSeconds := cBase;
while (not TryGetLocationLock) do
begin
if (lWaitMilliSeconds > cMaxWaitMilliSeconds) then
Exit(False);
Sleep(lWaitMilliSeconds);
Inc(lWaitMilliSeconds, lWaitMilliSeconds);
end;
end;

Visual Studio: In TFS how can I correct the links to work items on an existing changeset – Stack Overflow

Posted by jpluimers on 2017/01/17

This is still one of my gripes from Visual Studio: when a changeset is linked to an incorrect work item, you still have to change this from the work item side:

You cannot change it from the changeset UI, but you can change it from most work item UI’s. You can just add a link to a the specific changeset and the changeset will show the link as well.

You have to be careful with the steps too:

  1. Link it from the correct work item as a changeset link
  2. Unlink it from the wrong work item

If you do it in reverse order, and get the changeset number wrong, you will have an orphan changeset.

The Chernobyl Story [Updated & Expanded] – Album on Imgur

Posted by jpluimers on 2017/01/16

From the author of [WayBack] The Chernobyl Story [Updated & Expanded] – Album on Imgur:

I’ve assembled this collection of images surrounding the Chernobyl nuclear disaster to help people gain a better understanding of what happened. It is a very brief, but complete(ish) retelling of what happened, using edited text from a book I’ve written called “Chernobyl 01:23:40”. The book can be bought from Amazon, if anyone’s interested.

The book is even more impressive: “Chernobyl 01:23:40”

RSS feed for Dave’s Development Blog – mostly OTA articles on the Open Tools API for Delphi and C++ Builder

Posted by jpluimers on 2017/01/16

TL;DR: http://www.davidghoyle.co.uk/WordPress/?feed=rss2

Since there is no RSS link  on the page [WayBack] Dave’s Development Blog – Software Development using Borland / Codegear / Embarcadero RAD Studio

Since I wanted to follow his “blog” (which is sort of a collection of WordPress pages, mainly about the programming OTA: the Open Tools API interface to Delphi and C++ Builder), I was looking for the RSS feed.

Luckily, Feedly knows how to detect most blogging platforms, so it came up with https://feedly.com/i/subscription/feed/http://www.davidghoyle.co.uk/WordPress/?feed=rss2 which indicates the final bit is the RSS feed URL.

Some interesting links from there:
