You can still have the first, but nevertheless the second being active. Usually an UEFI BIOS can be made working as an old fashioned one. Unfortunately switching that back to UEFI mode requires some significant work to make Windows boot again.

Two things that are sometimes overlooked: UEFI BIOS TPM 2.0 For the second item there is an article (in German): Windows 11 läuft wohl nicht auf Intel-Macs

Build / Output messages filtering plugin
Uwe Raabe replied to CoMPi74's topic in Delphi IDE and APIs
AFAIK, there is currently no mechanism to intercept the message display via OTAPI. -
Apache Module with TDataSet Needs Wait Cursor
Uwe Raabe replied to corneliusdavid's topic in Network, Cloud and Web
Have you checked that opening the relevant FireDAC dataset (whatever is happening in dmParksDB.OpenParks) actually contains data on Linux? I mean, if there is no data in the dataset what can we expect?- 15 replies

Apache Module with TDataSet Needs Wait Cursor
Uwe Raabe replied to corneliusdavid's topic in Network, Cloud and Web
I get the feeling that is isn't related to the wait cursor, but the timer implementation that comes with either of the Wait implementation units. While both the VCL and FMX implementations use a TTimer (VCL/FMX), the console implementation simply doesn't support a timer at all.- 15 replies

Apache Module with TDataSet Needs Wait Cursor
Uwe Raabe replied to corneliusdavid's topic in Network, Cloud and Web
You can use the console cursor even in a VCL or FMX application. So setting the provider to Console should work in all cases.- 15 replies

Sorting classes is usually not working due to dependencies between them. You might have more luck using MMSDV to compare the files.

MulDiv( ) : Integer; in Delphi, cannot find this in the RTL (cross-platform)
Uwe Raabe replied to Rollo62's topic in RTL and Delphi Object Pascal
DIV and round(/) will give different results depending on input. -
[RadServer] User can not logon to multiple sessions simultaneously?
Uwe Raabe replied to mvanrijnen's topic in Network, Cloud and Web
QP is merely a bug tracker meant for collecting bugs from users and solve them somewhere in the future (well, in theory). With that in mind, two days are nothing. As the issue is not even opened, probably no one in charge has even took notice. If you want instant support you better open a support case. With an active subscription you are entitled for three issues per year. IIRC the URL is https://idera.secure.force.com/embtsupport/ -
Structured Difference Viewer added to MMX Code Explorer
Uwe Raabe replied to Uwe Raabe's topic in MMX Code Explorer
If the error just could be reproduced here in my environment, I would do. Nevertheless, I will add madExcept in the next release. -
Structured Difference Viewer added to MMX Code Explorer
Uwe Raabe replied to Uwe Raabe's topic in MMX Code Explorer
The stucture relates to the class and its methods as seen in the tree view to the left. F.i. if only the order of methods in a class changes, be it in the interface or the implementation, the structured difference would rate that as equal. Inside each method the diff is the same as a simple line diff. -

Looks pretty decent so far. -
Structured Difference Viewer added to MMX Code Explorer
Uwe Raabe replied to Uwe Raabe's topic in MMX Code Explorer
Googling that error code gives one usable hint: As I have not the slightest idea which DLL may be causing this I would like to ask if you can try some Sysinternals magic to find that out. It might be related to using Windows 7 and MMSDV being compiled with Delphi 10.4.2. -
That is quite similar to what TFDQuery implements with Cached Updates.
-
Same here. This also helps to keep the VM independent from the host. All my VMs are self contained and can be moved to arbitrary hosts (with capable hardware of course).

Out parameter is read before set
Uwe Raabe replied to Mike Torrettinni's topic in Algorithms, Data Structures and Class Design
And here it is: program Project804; {$APPTYPE CONSOLE} {$R *.res} uses System.SysUtils, System.Classes; function AddItems(const aArray: array of string; out aList: TStrings): boolean; var S: string; begin { can we really omit this? No! } //aList := nil; for S in aArray do if S.Length > 0 then begin if aList = nil then aList := TStringList.Create; // only create aList if any items gets added aList.Add(S); end; Result := aList <> nil; end; var lst: TStrings; begin try lst := nil; try if AddItems(['Hello', 'World'], lst) then Writeln('True') else Writeln('False'); if lst <> nil then Writeln(lst.Text); finally { uncommenting this will raise an invalid pointer exception later } //lst.Free; end; try { Although being an out parameter, the current lst instance will be used inside AddItems } if AddItems(['Delphi'], lst) then Writeln('True') else Writeln('False'); if lst <> nil then Writeln(lst.Text); finally lst.Free; end; except on E: Exception do Writeln(E.ClassName, ': ', E.Message); end; Readln; end. -
Out parameter is read before set
Uwe Raabe replied to Mike Torrettinni's topic in Algorithms, Data Structures and Class Design
Pascal Analyzer is trying to tell you: "Your method misses to initialize aList before entering the loop, because in case the loop is empty or condition is always false you end up with an uninitialized out parameter aList!" So, yes, it is a valid alert and although you may get away with it in most cases, it may fire back sometimes. It should be possible to create a use case where it fails. -
It is probably a button somewhere on the new CustomTitleBar control that is clicked. It can as well be that just the event of that button is wired also to some other button and no titlebar control is directly involved.

Unit Dependency Analyzer -- Not found items
Uwe Raabe replied to Bill Meyer's topic in MMX Code Explorer
Not found units are units that are referenced somewhere in the uses clause, but Analyzer cannot find the unit source for it. Usually that are Delphi units in dcu format. You can extend the search path of Analyzer so that it can find those units. On the other hand you might not even be interested in analyzing these units as you probably have no means to change any of these dependencies then shown. Usually it would only clutter the output. -
Delphi 10.4.2 always recompiling in IDE
Uwe Raabe replied to Dave Novo's topic in Delphi IDE and APIs
Seems it is not Classic Code Insight alone. I cannot reproduce with a fresh VCL application with either setting. -
I just realized that this is far more complex than I anticipated. The current implementation takes one or more lines and splits them each independently. If a line break is inserted, the remaining text is also handled as if it were independent. Unfortunately that will not work reliable when semantics come into play and some state has to be carried on. Seems I have to re-design the whole approach before it can be used in production.
-
Well, I am thankful for every test case. The test case should have: the complete line with leading spaces the expected length of the first line after wrapping the wrap margin to use (default = 80) the indent for the wrapped lines (default = 4)

Delphi 10.4.2 always recompiling in IDE
Uwe Raabe replied to Dave Novo's topic in Delphi IDE and APIs
Not something that I am aware of, but there are still areas in MMX which I am not very familiar with. MMX marks the project modified when the MMX settings dialog is closed with OK or Apply is clicked, but nothing of that happened in the video. The weird thing is that I made the test with MMX installed, too - and it did not happen. I do the same test with other projects and not one shows the always compile problem. Can you export the MMX registry key HKEY_CURRENT_USER\SOFTWARE\Raabe Software\MMX\15.0 and send it to me so I may track that down? -
Delphi 10.4.2 always recompiling in IDE
Uwe Raabe replied to Dave Novo's topic in Delphi IDE and APIs
As that matches my test scenario pretty close, it may be caused by some differences in our environment. Which plugins do you have installed? -
