Since "taskbar" aka "window buttons panel" (for most Desktop Environments) represents visible windows on desktop - you can't.

MainForm.Visible <> MainForm visible to the user. Set MainForm.Left to 10000 and you're good to go.

I do not understand what it means. but I try
Application.Mainform.left: = 10000;

1.on event "onshow" at form2 (not my mainform) ==> result (application.title) does not come out on the taskbar

2. in the project source ==> the result is an error.

Can you explain in more detail?

since I used Delphi 7, the application title problem never happened like this on Windows XP or Windows 7.

Then when I tried this Lazarus, I found a problem like this. I tried on Embarcadero 10.2 Tokyo also has a problem like this.

Is there a way to overcome this problem? Please also note that I tried Lazarus on Windows 10.

What OS?

MainForm.Visible <> MainForm visible to the user. Set MainForm.Left to 10000 and you're good to go.
How does that work with multimonitor configurations?

In Delphi 7, the application window (on the taskbar) is also hidden when the main form is hidden.
It's not very clear to me why this behavior is necessary, and how to manage a hidden application afterwards, but you can use an empty one instead of the main window with BorderStyle = bsNone; and Height = 0; and show/hide another window.

As I said above, window button on a taskbar is always hidden when corresponding app's window is hidden. It is a functionality of Desktop Environment, not application.

And yes, it is quite unclear, why someone needs to hide a window, but keep taskbar button visible. Looks more like a minimize behavior.
More often they need an opposite action: hide button from taskbar (optionally move icon to the tray) but keep window visible.

Looks more like a minimize behavior.

Indeed! And that's one possible way to implement it: Minimize the application and intercept/ignore any request to restore it. Doesn't sound so difficult, does it?

Indeed, I wonder if what you (young_nandy) really want is the TrayIcon ?  Sounds like you are using Windows, it works fine on Windows. Maybe you should have a look at how it works....

Sorry, the correct one is application.mainform.left

I will explain later below. I already understood the meaning of this trick.

please see the trick from "GetMem".

I will explain below. what I need is when form1 moves to form2, application title still exits on the taskbar. I use the following script

form2.show;
form1.hide;

Thank you for the idea, but I prefer the trick from "GetMem". mainform is not visible
