I have discovered that I can use the {$LONGSTRINGS OFF}
directive, is this a god way or should I typecast? It would be nice if
there were a switch that could be put in the CFG file that forced the
compiler to use short strings.

Can anyone share knowledges and ideas about when and > where and why a (pascal) developer should chose one over another? Depends on taste, and they have both advantages and disadvantages. For example, it's easy to see when flag-using code is coded correctly (are the return values checked and handled?), while it's hard for exception-using code. Exceptions are usually slower as well. Exceptions are also not compatible to other languages, usually. OTOH, using exceptions is lazier/easier. If an error should never occur, then using exceptions will have more readable code, as not every function calling this must handle the possible error flag.

It is much more easyer if you have products that have a good quality and if you have people who are interested in it. It will guarantee also that people who rely on the compiler that they have more security or may be they feel that someone is responsible for it. Absolute security is impossible.

while (Now - PreviousTime < 5 minutes) do

Sleep(1000); // May be bigger
end;
end;
You can use the Now function here because 5 minutes a lot of time, and
so you don´t really need a lot of precision.
If you needed a nanosecond precision on your loop you could use the
powerful EpikTimer component:

If you want to receive user input while your loop runs, then put the
loop on a separate thread.

I downloaded the httpd wrapper and examples from http://www.freepascal.org/wiki/index.php/FPC_and_Apache_Modules and can't start my Apache 2.2.3 server on Win2k SP4 when i include the mod_hello.so file compiled with FPC 2.1.1 and 2.0.4 Are there any known bugs with Apache 2.2? or the example doesn't works anymore?

Thanks Felipe,
Do you have an example of how to use this loop on a thread?
Sorry, but I don't know threads very well.

Write a loop that first stores the current time, then executed
whatever you need, and then sleeps until current_time - previous_time
= 5 minutes. Like this:
while (not Terminated) do
begin
PreviousTime := Now;
// Do what you need to do
{--
"sleeps" while currentTime - PreviousTime isn´t bigger then 5
minutes
--}
while (Now - PreviousTime < 5 minutes) do

[fpc-pascal] Find the nature of a pointer
Hello, I have a function that will receive a Handle. That handle could be a pointer to a structure, or a object. Is there any safe way to discover it's nature? The following code will work when the Handle is an Object or nil, but will crash the application when the Handle is a structure: function TQtWidgetSet.IsValidGDIObject(const GDIObject: HGDIOBJ): Boolean; var aObject: TObject; begin Result := False; if GDIObject = 0 then Exit; aObject := TObject(GDIObject); if aObject is TObject then begin Result := (aObject is TQtFont) or (aObject is TQtBrush); end; end; thanks, -- Felipe Monteiro de Carvalho ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Is there any safe way to discover it's nature? No, if only because there is no generic way to distinguish a random record which just looks like an object (because it happens to contain the right bytes at the right place) and a genuine object (or anything else for that matter). The only way would be to make sure all objects are allocated from a separate memory pool, and checking whether the passed address lies in this pool.
