Hiding your application from the Windows Taskbar.

Question:

How do I hide my application from the Windows Taskbar?

Answer:

It is possible to have your application running without an icon appearing in the task bar. Here's how to do this:

In Delphi go to the menu option Project -> View Source.
Add the Windows unit to the uses clause.
Add Application.ShowMainForm := False; to the line after
"Application.Initialize;".
Add: ShowWindow(Application.Handle, SW_HIDE); to the line
before "Application.Run;"

If you still want your form to show then Add: ShowWindow(Form1.Handle, SW_SHOWNORMAL); to the line just before "Application.Run;"

Your main project source file should now look something like
this:

program Project1;

uses
  Windows,
  Forms,
  Unit1 in 'Unit1.pas' {Form1},
  Unit2 in 'Unit2.pas' {Form2};

{$R *.RES}

begin
  Application.Initialize;
  Application.ShowMainForm := False;
  Application.CreateForm(TForm1, Form1);
  Application.CreateForm(TForm2, Form2);
  ShowWindow(Application.Handle, SW_HIDE);
  ShowWindow(Form1.Handle, SW_SHOWNORMAL); //Only add this if you want your form to show.
  Application.Run;
end.

In the "initialization" section (at the very bottom)
of each unit that uses a form, add:
```
begin
  ShowWindow(Application.Handle, SW_HIDE);
end.
```
