TEST

Another Test: lets go crazy

I want to create a boxed text:

This is in a box, or so I hope.

This is outside the box, no? And this is a reference to my incomplete Structural Analyis book ThisIsMyShura

Weird: this is in the box as well?

• And a bullet in italics?

non formatted...

Float Like A Butterfly

New section?

Let's see... ok

grusskarte

if Graphviz was installed, this would draw a pretty graph...

<graphviz> digraph G {

 rankdir=LR; node [fontsize = "8" shape = "rectangle"]; 
 "Node 1" -> "Node 2";

} </graphviz>

This is a test to see, if I can edit a page after the Bad-Behavior update. fpcfan 22:43, 7 December 2007 (CET)

Test whether an Application is already running

Here's a unit that works under both Windows and Linux

• There's no need to pass the full application path to the function - the ExeName will usually do. Below code cannot find out its own exename though.

unit uappisrunning;

{$mode objfpc}{$H+}

// Don't pass an .exe extension to Linux!
function AppIsRunning(const ExeName: string):Boolean;
