Streams don't know about encoding. You might better do with a TStreamReader. In its FillBuffer method there is some code taking care of your concern (look for ExtraByteCount).

AFAIK that is not available in the Professional version. The feature matrix seems to support that information:

The message is thrown inside the CheckActive method of TDataSet. I also suggest some debugging session. I guess the reason lies at place you don't expect.

The right most button in the toolbar

has a drop down menu where you can configure the sort order.

If the query is a SELECT statement or something that also returns a record set you should use Open instead of Execute. Therefore you should add a Close before changing any parameters.

Whatever you implement, you should always measure the performance against the brute force update.

If the server were a recent InterBase one, you could make it simple and fast with Change Views, but these are not available with other databases.

Why so complicated? Dump DOCS_TABLE and rebuild it from scratch - assuming you actually have access to the server. Otherwise you have to work with the data available in DOCS_TABLE anyway.

Can Lazarus make use of any font in the editor? Even the non-monospaced ones?

has a parser that works in the background

That's basically what MMX does, too. Besides the IDE itself (with active CodeInsight) there may as well be other plugins spawning their own parser process. This bothers me for years now. It might get better when LSP is up and working reliably, but that might take a while and will be restricted on newer Delphi versions.

Thanks for the tip, though. 👍

and set the owner correctly

That may be key here. Before looking for global components all components owned by the current one are searched (Keywords: DoFixupReferences, FindNestedComponent). So if your datamodule is owned by the form it should be found first. You may probably even omit the renaming step after loading.

I am still trying to find where Delphi replaces component references. I think it could well be at the streaming stage.

Indeed, it is! The references are resolved in TReader.FixupReferences and are based on component names. To wire the datasource on the datamodule to the controls on the form, the datamodule has to be created before the form loads. As all forms and datamodules register themselves in the Screen.Forms and Screen.Datamodules lists, they are found by simply iterating over these lists in the Vcl.Forms.FindGlobalComponent procedure, which is registered via RegisterFindGlobalComponentProc.

You can register your own FindGlobalComponentProc this way, which takes precedence over the internal one (System.Classes.FindGlobalComponents uses a reverse loop). The implementation might be a bit tricky, though.

10.2.3 dragging dose not work

You have to be inside a debugging session. 

Dragging works, too. At least here in 10.3.3:

I took a few lines of code and moved them to watch list

I guess we are talking about valid expressions and not arbitrary code.

BTW, even arbitrary code can be pasted or dragged into the watch list. Often that doesn't make any sense, though, as most of the time you will see an E2156 Expression too complicated.

Often the time spent for low priority tickets would better be used for refactoring the code - even if the only benefit is the developers better understanding the code and ease maintaining it. That might not impact your customers directly, but definitely on the long term. First implementing that low priority ticket instead may as well have the opposite effect.

There is no "IDE Insight toolbar" item in my list of toolbars in Delphi Rio 10.3.3:

Seems as the IDE Insight toolbar is not part of the toolbars anymore, there is no way to reset it as described.

It seems that the "wuppdi Welcome Page" is the culprit.

Well, the wuppdi Welcome Page options provide a checkbox for "Include Favorites in IDEInsight". It might help to just disable that one.

Perhaps the same as happened to me a while ago? When IDE Insight suddenly stops working…

OK, there is an undocumented option poSkipUnmatchedDestFields which you can set to False (although I don't know what it does).

Can't you just delete the table before executing the batch move?

I have been conditioned to expect top of category pages to be empty,

I always have the feeling of wasted with that.

MMX - Properties - Key bindings - Move Entity Down/Up

I guess I have no control over that. You can change the shortcuts for these functions, though.

Because a bug-reporting system is literally full of bugs.

BTW, may need to keep your IOTAProjectFileStorageNotifier implementation, because FileNotification is not fired during a file reload triggered by an external change (f.i. initiated by a VCS action).
