Reminder to self: check out “Debugging helper for TDataSet” and “debugger TDataSetVisualizer” for Delphi
Posted by jpluimers on 2018/04/24
So I won’t forget to check these out:
- [WayBack] Debugging helper for TDataSet – twm’s blog by Thomas Müller
- [WayBack] TDataSetVisualizer: Delphi IDE Debug Visualizer to view a TDataSet descendant within a DBGrid. by Darian Miller
Via [WayBack] I like programming in Delphi, but I don’t particularly like writing applications that work with database backends… – Thomas Mueller (dummzeuch) – Google+ (thanks Stefan Glienke)

How to embed a superscript Registered symbol in a Rave memo buffer.
Posted by jpluimers on 2018/04/24
Thomas Pfister came with a nice solution to this question:
[WayBack] Does anyone know how to embed a superscript Registered symbol in a Rave memo buffer? – Phillip Woon – Google+
Since Google has such bad indexing of G+, here is the solution:
procedure TForm4.RvSystem1Print(Sender: TObject);
const
SuperscriptOn = RPTFPrefix + RPTFSuperscript + RPTFOn + RPTFSuffix; // from RpDefine.pas
SuperscriptOff = RPTFPrefix + RPTFSuperscript + RPTFOff + RPTFSuffix;
var
MemoBuf: TMemoBuf;
begin
MemoBuf := TMemoBuf.Create;
try
MemoBuf.Text := 'Test' + SuperscriptOn + '®' + SuperscriptOff + ' Test';
MemoBuf.PrintStart := 0.5;
MemoBuf.PrintEnd := 8.0;
with Sender as TBaseReport do begin
PrintMemo(MemoBuf, 1, true);
end;
finally
FreeAndNil(MemoBuf);
end;
end;

Tip for the doc team: make TMonitor.Enter docs more clear on non-blocking re-entry from the same thread
Posted by jpluimers on 2018/04/19
Even when the Delphi team was large, the documentation was lacking, so with the reduced Delphi team size, I don’t have high expectations of the below to get fixed.
But since much of the post Delphi 7 run-time library looks a lot like the .NET core, you can usually fallback to the Microsoft documentation.
Tip for the doc team: make http://docwiki.embarcadero.com/Libraries/en/System.TMonitor.Enter more clear. Especially that if the same thread calls TMonitor.Enter more than one time, it will allow entry without blocking as per System.Threading.Monitor.Enter Method (Object) documentation https://msdn.microsoft.com/en-us/library/de0542zz
(note that this got introduced in Delphi XE3: http://docwiki.embarcadero.com/Libraries/XE3/en/System.TMonitor.Enter)

Reminder to Self: `TProc` is incompatible with parameterless procedures on interfaces
Posted by jpluimers on 2018/04/19
I knew that methods on interfaces were not compatible with the procedure of object (like [WayBack] TProc)or function of object construct, but they are also not compatible with the reference to procedure or reference to function construct.
Via: [WayBack] I try to call an Interface method from TThread.Syncrhonize()…and Berlin don’t accept that… – Paul TOTH – Google+
If you want it fixed, vote for [RSP-13007] Interface methods are not assignable to anonymous method variable – Embarcadero Technologies (Thanks Stefan Glienke).
You can work around it with an anonymous method.
This won’t work:
program Project1;
{$APPTYPE CONSOLE}
uses
SysUtils;
type
ITest = interface
['{B5AD87E8-A3DF-4B83-BE14-997C2E76A06C}']
procedure Run;
end;
TTest = class(TInterfacedObject, ITest)
procedure Run;
end;
procedure TTest.Run;
begin
Writeln('PASS')
end;
var
test: ITest; // <- change this to TTest and it compiles
proc: TProc;
begin
test := TTest.Create;
proc := procedure begin test.Run; end; // <- this compiles
proc := test.Run; // E2010 Incompatible types: 'TProc' and 'procedure, untyped pointer or untyped parameter'
proc();
Readln;
end.
