specializing it?
I assumed
generic TMyMap = class(generic TFPGMap)
...
end
but fpc 2.6.2 did not accept t
There are quite some features I want to use there but I would wait until
they are released a stable version.
Any idea?

>2.7.1 will become 2.8 sooner or later (*) and what's in trunk at that
time will also be in 2.8.0 (and normally we don't deliberately remove
things... ^^ ).
what is the timeframe of 'sooner or later'? May I assume Q1 of 2014?

I think I found a bug in FPC 2.6.2.
In a method of a derived specialized class, the compiler does not raise
error (which it should)
With "record property" do
"record property's field" := NewValue //it should raise error
since it is a record property and should not be allowed to modify just
Is there a way to further simplify the following?
I need to make the exception message more indicative of the context of
the error and I hope to combine the 2
try blocks into one.
It seems possible in Java and C# but not in FPC.
Is there a way to combine them like
try
except
finally
For what it's worth, I'm ambivalent. Not because I feel that try
stacks couldn't or shouldn't be simplified, but because I feel that
whoever overloaded try for two different structures should be shot.
I don't know enough about compiler. Could you kindly elaborate on the
above please?

I tried to read the mac address in the captioned file path.
In terminal, I can simply 'cat' and display the mac address.
In FPC, when I tried to use TFileStream to read it,
FS := TFileStream.Create('/sys
I created a TMemoField in TBufDataSet but no matter I do:
1) Field.asString := 'some value'
or
2) Field.LoadFromStream(someStream).
Afterwards, this F.AsString always returns ''
and
F.LoadFromStream(someStream) always has a 0 BlobSize afterwards.
Anyone has similar experience?

All the other usual types (e.g. integer, string, datetime) work except
ftMemo and ftblob.
Yes, I have used POST

Data are not there until you Post record.
After Post you will see data there, right?

Is TSQLQuery.AppleUpdate works with UTF8 string field content?
I fetched a web page and extracted part of its content and appended it
into TSQLQuery record's string field.
The web page content is Chinese in UTF-8 encoding.
I 'writeln' the content before appending it and it appeared normal in
1 - 100 of 168 matches
