I'd say it looks like you want a Service (NT/2k/XP) and not a regular application..
If that's the case, and it doesn't need to run on 9x, In Delphi 6 go: File -> New -> Other, and pick "service" from the available templates. Of course, read the help so you understand how services work, and what they can/cannot do.
hello mythos128, you can program just in your "Program" file (the .dpr), and do many things, woth API functions, but you WILL NOT be able to recieve windows messages.
Here is some code for a program that creates a Folder and writes a text fie in it - - -
program Project1;
uses
Windows;
{$R *.RES}
var
File1: TextFile;
{variables are put here}
begin // main program begin
if CreateDirectory('C:\Some Test Folder', nil) then
{securityAttributes are nil}
begin
AssignFile(File1, 'C:\Some Test Folder\test note.txt');
{use the delphi text file procedures defined in the System unit}
{$I-}
Rewrite(File1);
{put the $I compiler option so exceptions will
not be generated and stop this program}
{$I+}
{test the IOResult for success}
if IOResult = 0 then
Write(File1,'ParamStr 0 is '+ ParamStr(0));
{$I-}
CloseFile(File1);
{$I+}
end;
end.

Thank you all for your comments.
HillGroover: I don't want my app to have Forms and other stuff. It bloats the executable. I need a server app without any GUI.
asymmetric: My app must run on 9x too, so making it a service isn't a way out.
Slick812: Yes, that's what I need. In fact, your program differs from a regular console app only because it doesn't have {$APPTYPE CONSOLE} directive. I'm really ashamed that I didn't come to it myself... You deserve the points.
> but you WILL NOT be able to recieve windows messages
Well, if I needed Windows messages, I could easily establish a window and a message pump, couldn't I?
I guess that easily depends on your experience. . . yes you can do anything in the .dpr that you want, if you are interested in creating an API GUI windowed app look at -

Hi mythos128,
use this code in your projects source (*.dpr) file,
program Project1;
uses
Windows, // this needs to be added to hide the window and the taskbar button
Forms,
Unit1 in 'Unit1.pas' {Form1};
{$R *.res}
begin
Application.Initialize;
Application.ShowMainForm := False; // stops the application showing the main window (ie Form1)
Application.CreateForm(TFo
{The Next 3 Lines hides the taskbar button}
ShowWindow(Application.Han
SetWindowLong(Application.
GetWindowLong(Application.
Application.Run;
end.
assuming that you have controls on a form(s) that you want to use. then add this at the very end of any unit (just before the last "end.") you have in your project that uses a form,
begin
ShowWindow(Application.Han
end.
this will stop the program displaying any windows or taskbar buttons and should be sufficient for what you've described.
