When I run the code I get some error
I am not a PowerShell expert I have referred online documents and code and wrote this code so please help me out
My code :

I want you to write a PowerShell script that has a GUI good looking and has written in at top left corner xyz
and upper right corner IP blocking automation
and below it should have a big input area where we can only add 1 IP in 1 line without space
It should check IP conditions for each IP and also it should not allow to add IP of subnet 111.112.44.0/24 111.112.45.0/24
Also it should allow to add only public IP not private IP
make the GUI bit colorful and add a xyz logo to it
at the bottom of input field there should be a Add button
Show error above input field
Also when you click on add button try to fill a text file with the valid IP
tl;dr
Your New-Object syntax was incorrect.
Use either (applies analogously to all your New-Object calls:
# New-Object requires *argument syntax*:
# Note the (...) around the subtraction only.
# The first argument positionally binds to -TypeName,
# the second one to -ArgumentList
New-Object System.Drawing.Point ($Form.ClientSize.Width - $LabelAutomation.PreferredSize.Width - 10), 10
or, preferably, in PSv5+, using the intrinsic static ::new() method that PowerShell exposes on all types for calling constructors, which enables use of true method-call syntax:
[System.Drawing.Point]::new(
$Form.ClientSize.Width - $LabelAutomation.PreferredSize.Width - 10,
10
)
As for what you tried:
New-Object System.Drawing.Point($Form.ClientSize.Width - $LabelAutomation.PreferredSize.Width - 10, 10)
is an example of - unfortunately very common - pseudo method-call syntax, which is best avoided:
The (...) part after System.Drawing.Point looks like a list of arguments in a method call, but it isn't; while in practice that often does not matter, in the case at hand it does.
Your call is the equivalent of the following New-Object call:
# !! BROKEN
New-Object -TypeName System.Drawing.Point `
-ArgumentList ($Form.ClientSize.Width - $LabelAutomation.PreferredSize.Width - 10, 10)
New-Object, as a command (cmdlet) operates in PowerShell's argument[-parsing] mode, i.e. it is invoked like a shell command, with whitespace-separated arguments, with no need for (...) enclosure as a whole.
Argument mode has different parsing rules than expression mode, and within expression mode the syntax for the list of arguments in a method call (e.g. .someMethod(..., ...)) is subtly different yet again.
In argument mode - and even in a (...) enclosed expression outside of a method call - , doesn't separate arguments, it acts as , the array constructor ("comma") operator:
The , operator has surprisingly high precedence, so that an expression such as 10-5, 2 is parsed as 10 - (5, 2), i.e. an attempt to subtract an array from the number 10 - this results in the error you saw:
# !! BREAKS, because it is the same as: 10 - (5, 2)
Write-Output (10-5, 2)
