When applying for an internet connection with xs4all and specifying a different billing address, other letters still arrive at the address where the internet connection resides.
I had that, and didn’t want it: [WayBack] Twitter / Notifications. You might not want it for different reasons.
After contacting the web care, both sides learned there are three addresses:
according to the webcare person, it looked like you can only change the “contact address” through the service desk. You can, so that information is still below.
But contacting the service desk revealed that you can also perform two address changes on-line after logging in to https://mijn.xs4all.nl.
Of course you cannot change the service address as it is where your physical internet connection resides.

Reminder to check out if this book about “the calm company” has been released yet: [WayBack] It doesn’t have to be crazy at work.
Basecamp is an interesting company that has put action there there mouth is:
Trusted by millions, Basecamp puts everything you need to get work done in one place. It’s the calm, organized way to manage projects, work with clients, and communicate company-wide.
…
We’ve designed our company differently. We’re here to tell you about it, and show you how you can do it. There’s a path. You’ve got to want it, but if you do you’ll realize it’s much nicer over here. You can have a calm company too.
No, it is not The Little Book Of Calm, or another one of that series (;
If it is not yet out, you can still pre-order from Amazon in the USA and Europe:

A while ago, Marjan Venema was in need for [Archive.is] Delphi SOAP: delete temporary file after response dispatched – Stack Overflow.
The solution there is a truly temporary file: a file stream that when the handle closes will have Windows delete the file by setting the correct flags.
The construct is functionally identical to the JclFileUtils.TJclTempFileStream [Archive.is].
It passes these [Archive.is] file attribute constant flags to the [Archive.is] CreateFileW Windows API function:
FILE_ATTRIBUTE_TEMPORARYFILE_FLAG_DELETE_ON_CLOSEI was glad she asked, though I wanted a temporary file to last after debugging, so I wrote code like this because internally the same FileGetTempName method is used by the JCL:
var
// ...
TempPath: string;
TempStream: TFileStream;
TempStreamWriter: TStreamWriter;
begin
// ...
TempPath := FileGetTempName('Prefix');
TempStream := TFile.Open(TempPath, TFileMode.fmOpenOrCreate, TFileAccess.faReadWrite, TFileShare.fsRead);
try
TempStreamWriter := TStreamWriter.Create(TempStream);
try
TempStreamWriter.WriteLine('Debug starts:');
MyStringList.SaveToStream(TempStream);
TempStreamWriter.WriteLine();
// ...
TempStreamWriter.WriteLine('Debug finishes.');
finally
TempStreamWriter.Free();
end;
finally
TempStream.Free();
end;

I bumped into this a while ago, but since I’ve been doing quite a bit of research lately, it’s worth repeating.

I stumbled over this commit message in [WayBack] “extended the TestAttribute with “Expected” property (#181)” which isn’t phrased correctly, but adds a very nice feature.
The feature is about WillRaiseAttribute:
constructor WillRaiseAttribute.Create(AExpectedException: ExceptClass; const AInheritance: TExceptionInheritance);
This allows tests like these:
[WillRaise(EOutOfMemory)]
procedure FailMe;
[WillRaise(EHeapException, exDescendant)]
procedure FailMeToo;
[WillRaise(Exception, exDescendant)]
procedure FailAny;
[WillRaise(EOutOfMemory)]
[Ignore('I am not behaving as I should')]
procedure IgnoreMeCauseImWrong;

A while ago, I needed several enum types in the same unit with overlapping enumeration values.
Putting each in an encompassing type wasn’t possible and I didn’t want to put each in their own unit.
Luckily, Delphi 2009 introduced the “scoped enum” feature effectively promoting the enumeration type into a scope or namespace.
It is only available at the source code level, as – at least up until Delphi 10.1 Berlin – it is not part of the compiler settings in the project options (see screenshot below).
Since the below was hard to find combined with the word “namespace” I’ve quoted it in full (note an earlier version of the post had a typo here as it was copied from the Delphi 2009 documentation which had SCOPEDEUNMS wrong):
Remarks
The $SCOPEDENUMS directive enables or disables the use of scoped enumerations in Delphi code. More specifically, $SCOPEDENUMS affects only definitions of new enumerations, and only controls the addition of the enumeration’s value symbols to the global scope.
In the {$SCOPEDENUMS ON} state, enumerations are scoped, and enum values are not added to the global scope. To specify a member of a scoped enum, you must include the type of the enum. For example:
type TFoo = (A, B, Foo); {$SCOPEDENUMS ON} TBar = (A, B, Bar); {$SCOPEDENUMS OFF} begin WriteLn(Integer(Foo)); WriteLn(Integer(A)); // TFoo.A WriteLn(Integer(TBar.B)); WriteLn(Integer(TBar.Bar)); WriteLn(Integer(Bar)); // Error end;Note that this is also valid:
Writeln(Integer(TFoo.A));Even though TFoo was not declared with $SCOPEDENUMS ON, the A value can still be explicitly resolved using the enumeration name.
