Re: fpGUI Toolkit v0.8 release for FPC 2.4.4 & 2.6.0-rc

Paul Breneman — 2012-05-25T17:14:48

I've recently added new releases for Linux and ARM Linux on this page:
   http://www.turbocontrol.com/easyfpgui.htm

Also a few new releases on this page (including a note on how I recently 
got ppcarm 2.6.0 working for console programs on my Android phone):

You should do: 

type 

 MyVarArray = array of variant; 

and then


procedure TUnyokedFrontendForm.OutputWriteF(const str: widestring;

values: MyVarArray; fg: TColor= clBlack; bg: TColor= clDefault);

Format uses a different array type, they are not variants. 
You'll have to convert the arrays.

Re: Proposed FPC database example code: request fortesting

Thanks for the quick and helpful response, Michael.

I added it to the bottom of the post instead ;)

Firebird sounds good, define... why not (though it seems like a bit of
overkill)

Ok, though I don't see that much advantage to it unless you want to
separate the connection/console functionality out into a class... sorry
object that can be instantiated. Which does make sense.

Wasn't aware of its existence... or forgot about it... ;) Looks like
pasql could do with a rewrite then...

Thanks,
Reinier

I'm willing to include it as an example in fcl-db, but then you'd need to 
make some improvements first:

   MS-SQL does not make sense. I'd go for firebird, but I suggest

- Clean up the code so it is separated out in a unit, not in the program file ?
- Why not use the TSQLConnector component ? You repeat what it does already ?

Any of the improvements you suggest are fine too, of course.

Proposed FPC database example code: request for testing

Reinier Olislagers — 2012-05-25T08:17:01

Hi list,

I've created a small SQL*Plus/isql/osql/sqlcmd clone, pasql.

It lets you connect to a database and run select queries as well as
queries that don't return a dataset.
It also shows how to use logging.

Perhaps it's a nice candidate for inclusion as an FPC example, but it's
only been tested/known to work on Firebird 2.5 server, MS SQL Server
2008 and Sybase ASE15.

I'd be interested in suggestions for improving the code (e.g. the ODBC
code probably needs work), bug reports with other databases (PostgreSQL,
Oracle,...)

Thanks,
Reinier


Pasql
=====
Pasql is a sample tool that lets you connect to an SQLDB supported
database and run SQL commands.

It logs your commands and can print them at the end of the session.

To run this, you need to have the relevant database client drivers/dlls
installed (e.g. in Windows, you can put them in the directory where
pasql.exe is)

Run pasql -h for help.

Concepts

This program demonstrates:

TP 4 to FPC 2.6.0 conversion

Robert Zimmerer — 2012-05-23T16:59:40

My conversion of TP 4 programs into FPC 2.6.0 to obtain hi res graphics on Win2000 OS is almost complete. My program starts in a VGA type window requesting a keyboard input and then opens into a full screen graph mode window, 1023 X 720 pixels, behind the small VGA window. I must click on the full screen window to bring it on top and gain keyboard control.

What FPC commands exist to instruct my converted program to put the full screen on top when it enters graphic mode?  I use the IDE which came with 2.6.0.  I adapted Mandel.pp graphics code.

Thanks for suggestions  RwZ_______________________________________________

As far as I know you can pass ShortString of any size to a ShortString 
of maximum length (255). So I don't see how "var a : ShortString" would 
lead to errors. But of course, you need to be careful.

Nevertheless, I would rewrite such code. Even at the danger of breaking 
something else (which would hopefully appear directly) I would consider 
clear code so important that I would not rely on some compiler switch
