[fpc-pascal] Yet again Objects auto destruction
I think it is not the first time this topic was opened, but still think we need when using object to have automatically destructor called by compiler when the object freed TmyObject = object FSQL: TStringList; constructor Init(SQL: string); destructor Free; end; constructor TmyObject.Init(SQL: string); begin FSQL:=TStringList.Create; end; destructor TmyObject.Free; begin FSQL.Free; end; Here in the example we can call init manually and it is not a problem, because it is always we know who is create this object. But free or destroy can not call it manually, we not know who will kill that object first, because many of another object assigned to it.

What needs to be modernised about it? It's not like our disk i/o error code handles many more different error codes, nor are those errors much more specific. I remember the old discussion, but I never understood how the error reporting of the sockets code and the generic I/O code differed in a way that made the former worse than the latter. That would also make it possible to directly map socketerror to getlastresult/fpgeterrno, instead of caching it in another threadvar. IIRC the problem with removing socketerror would be that it could easily break existing code (given that socketerror is not overwritten by calls other than those from the sockets unit).

But if the SQLite unit in another repository, this Extended repo can published the releases more faster than FPC releases, If FPC release come one every year this repo collected and released 4 time in this year.

You can use a small helper function like this:
type
TInfo=record
s: string;
i: integer;
end;
function makeinfo(s:string;i:integer):TInfo;
begin
result.s:=s;

Hi,
While implementing drag-n-drop support in fpGUI, I created a
TfpgMimeData class. This class will hold various data items, and a
mime-type describing each of the data items. Obviously the
TfpgMimeData class should be able to handle any data type. So my
question is, what is a good universal type to store all kinds of data
(strings, images (binary data), sound etc)?
The possible ideas I can think of is the following:
TByteArray
Variants
TMemoryStream
So which one would be more fitting for any mime types, or is there
another option I didn't think of? Here is a simple usage example of
the TfpgMimeData class - to help put this in perspective:
var
m: TfpgMimeData;
d: TfpgDrag;
a: TfpgDropAction;
begin
m := TfpgMimeData.Create;
m.SetData('text/plain', 'My name is Earl');
m.SetData('text/html', 'My name is bEarl/b'); // text/plain
can actually be created from this automatically
m.SetData('image/png', MyPNGImage);
d := TfpgDrag.Create(self);
d.MimeData := m;
d.StartDrag([daCopy]);
// d manages the lifespan of m
// d will be freed automatically when drag action is complete or
cancelled
end;
Just initial idea.
TfpgMimeData class(TfpgDragData);
Picture:TPic ...
end;
var
m: TfpgDragData;
d: TfpgDrag;
a: TfpgDropAction;
begin

Well, apparently Delphi 6 RTTI thinks that it is a float. Check this code: 471 else if ElmTypeInfo.Kind in [tkFloat] then begin 472 case TypeData.FloatType of 473 ftSingle: Stream.Write(DynArray^, ArrayLength * SizeOf(Single)); 474 ftDouble: Stream.Write(DynArray^, ArrayLength * SizeOf(Double)); 475 ftComp: Stream.Write(DynArray^, ArrayLength * SizeOf(Comp)); 476 ftCurr: Stream.Write(DynArray^, ArrayLength * SizeOf(Currency)); 477 ftExtended: Stream.Write(DynArray^, ArrayLength * SizeOF(Extended)); 478 end; A Currency is a Int64 not float, if you assign currency to float variable (double/extended) and return back to currency variable, you will not get the same value. Typecast the currency as Int64, assign it to int64 variable and vise versa you will not lose any thing.

[fpc-pascal] Initialize the object (not class)
I have used object to make more easy, not need to create or free it, MyObject = object private FProp1: integer; public Prop1: integer read FProp1 write FProp1 procedure Proc1; end; used like var O: MyObject; begin O.Proc1; end; 1 - The problem, i have random value in the prop1(I am not sure about it), is that mean i must initiliaze it. 2 - is there a method i can override it to init my properties without to call it manualy O.init; Thanks in advance -- Zaher Dirkey ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

While we are on the topic of CGI and Apache. Any idea how to tell
Apache that a specific file is a CGI program, even though that file
has no file extension like the obvious .cgi suffix? This is not to
serious - I think Google accepts URLs with a '.' (dot) in the path.
eg: http://www.mydoman.com/mmaths/project1.cgi/myparam
in .htacces with rewrite mode is enabled, it easy to convert new style to
old one
RewriteEngine on
RewriteRule ^$project1.cgi [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) project1.cgi?action=$1 [QSA,L]
RewriteRule ^project1.cgi$ project1.cgi
And you have many examples on internet to understand RewriteEngine
