Renaming private (existed in implementation section) procedure/function parameters does not propagate to the procedure body.

Please try edit this function and change InString to something other.

function StrToIdBytes(const InString: string): TIdBytes;
var
  ch: Char;
  i: Integer;
begin
  SetLength(Result, Length(InString));

  i := 0;
  for ch in InString do
  begin
    Result[i] := Ord(ch);
    inc(i);
  end;
end;

I get error after open Viewer and trying close it by X button.

And now only killing the process can close Viewer app.

Delphi 10.3 and Windows 7.

Does a files search from within the IDE (shift+ctrl+F), with Regular Expression enabled, support multi-line searches? I tried for an hour and did not get anything.
For example, I would like to find all public var sections located between interface and implementation in units.

Can the IDE do this?

I'm working on Ryzen 5900X, the computer after switching from i7 3770 got such wings that I close the windows to keep it from flying away 😉
I work in a virtual machines (vmware), currently I have 2 machines open. The system on the host is Ubuntu, which has very low requirements and low overhead. The ram usage (including the two virtuals) is currently at 10 GB (and I have Firefox open with many tabs, Slack, Telegram and many background services).

I strongly recommend AMD

Is it possible to automatically convert the entire Firebird database from win-1250 to UTF-8 encoding? Are there any tools for this purpose? Or using backup/restore?

February 15, 2021

Yes, you're right... it's about the padding. I didn't specify it explicitly and the default was used, hence there is a difference in the two libraries. Thanks!

I am testing the DEC library and the AES algorithm (Rijndael).
To check the correctness of the result I use other sources of ciphertext. And I encountered a small problem.
I used two online generators and wrote a script in Python, but the results (ciphertext) has different length in each of them:

The common part agrees, but what are the extra bytes?

Python script:

key = b'01234567012345670123456701234567'
plaintext = 'Some short description with looooooooong additional data like polish diacritical chars... łóżźćęół and digits 0123456789'
encrypter = pyaes.Encrypter(pyaes.AESModeOfOperationCBC(key))
ciphertext = encrypter.feed(plaintext.encode('utf-8'))

Simplified version of the question: is it possible to pass a memory area (pointer) to a method that accepts an array of bytes (TBytes) without copying?

If it's not possible, there's no trick, that's too bad. I'm looking for another solution. Thanks for the help...

February 9, 2021

I have a method (from external code) that takes an array of TBytes as a parameter:

procedure Something(const aData : TBytes);

and I need to pass to it a (read-only) memory area, allocated by GetMem().

Is it possible to cast this to TBytes (or some other trick) without copying the memory to a separate variable of type TBytes?

I guess I finally found the cause: When you edit a property inside an interface the available visibility values are limited to default. Now edit a property in a class and the visibility is also default. The reason is that the current visibility is set before the allowed values are set.

I don't think I've written anywhere, but with me practically 99% of classes implement the interface, so there is always an interface behind the class and problems with moving methods to the beginning of the class were ALWAYS present in classes implementing the interface.

A fix will be available shortly.

Can you check if you have Pick up any style comments as documentation checked in your MMX Documentation settings? That would take the commented method declaration as a comment belonging to the one below. Consequently the comment is moved together with the method declaration.

Yes:

I am very happy that I will enter 2021 without this frustrating affliction

Happy New Year!

Unfortunately, after editing many methods, the problem appeared again, so this value has no effect 😞

Perhaps the line width is important for this problem. I had 140, now I set 80 and for now the situation has not repeated, I will test for some time, although I want 140 eventually.

I don't use Indexer on a daily basis, but I thought I would use it because I wanted to look for many things in the code quickly. I opened its window, indexed the project and started searching. But after hovering the mouse cursor over the name in the indexer window I get AV. This is related to the hint window, as shown in the log.

The error is repetitive, every hovering the cursor generates AV:

Firedac datasets have the method DestDataset.CloneCursor (SrcDataset : TFDDataset...), which clones the cursor from the dataset given as a parameter. After performing this method internally both datasets have the same buffer with records.

Is there any way to reverse/cancel the result of this method, i.e. break the links to the "foreign" buffer and recreate the original cursor/buffer? I mean especially TFDMemTable.

A tool to convert database files from Firebird 2.x to 3.x, in other words a database file structure converter (ODS) from version 11 to 12.
An editing tool for both Windows and Linux, in the form of scripts.

No need to install Firebird server!

I invite you to use it.

Firebird version 3 is already very mature and it is time to migrate from version 2.x 😉

This is not the solution I am looking for, I can save and load a dataset content without such "tricks".

I'm interested in ADDING a new lookup field with an ACTIVE dataset.

Is there any way to add a lookup or calculated column to an open dataset? Normally a dataset needs to be closed, but in my case I lose data (this is TFDMemTable), so I would like to add columns on the active dataset.
I will add that lookup fields are not data fields and are not included in the data buffer, so there should be some way to add them.

@c0d3r

I guess you write to me.
Well, you're wrong. The database has declared UTF8 type for text fields. The connection is also made with the parameter UTF8.

I guess I was in too much of a hurry with this report. I guess that's because I was very annoyed by this mistake before.
Now, after restarting the machine, the bug doesn't appear anymore, even though I have already entered the settings several times.
If something happens, I will let you know.

Once, in Delphi 10.2, I had an identical problem, the cause of which I could not trace. The problem was that the Options window (menu Tools->Options...) was blocked by an exception.

To enter Options I had to use GExperts to deactivate all the experts, restart the IDE, enter Options, set what I needed, reactivate all the experts in GExperts and restart the IDE. I did not know what caused this problem.
I haven't had this problem since I migrated to Delphi 10.3... until now. I just installed the Selective Debugging expert 😞

Additionally, I see that in D10.3 this exception does not appear, as it used to, every time, but sometimes. For example, a moment ago I entered the options without any problem.

ps. I'm sorry to write about it here, but I don't know where it would be better to report it.
