I am trying to make a simple python script that is not working when it is in the folder: "C:/Users/UserName/AppData/Roaming/Microsoft/Windows/Start Menu/Programs/Startup" in windows 10
So I have made a python script without console (.pyw), which is run when the pc starts and the user has logged in. After that, a Tkinter fullscreen topmost window will appear with an image on it. The script has to be in the Startup-folder to run when the user has started the pc and logged in. Inside the startup-folder is also a .jpg image which is the one that should be showing.
The problem is that if I run the script manually from inside the Startup-folder everything works, but when I restart the pc and log in, the Tkinter window doesn't open, and instead the Windows image viewer program opens up showing the desired picture, but not a Tkinter window.
This is probably because if I run this code inside the folder by manually double clicking the script I get this result:
from pathlib import Path
Path.cwd() #Should give the file path from C: to the running script
C:/Users/UserName/AppData/Roaming/Microsoft/Windows/Start Menu/Programs/Startup
While if I keep this script in the folder and restart the pc instead I get this result:
C:/WINDOWS/System32
This must mean that when I run the script manually it will run via the first file path, while if I restart the PC it runs it through another file path. This might be somehow interfering with my code.
The reason why the Windows image viewer program shows the image has maybe something to do with .show(), which is the line of code that opens the Windows image viewer program to show the image with the variable name .
This is the code with added comments:
import tkinter as tk
from PIL import ImageTk, Image
root = tk.Tk()
root.attributes('-fullscreen',1) # Making the window fullscreen
root.attributes('-topmost',True) # Making the window topmost
root.title('<title>')
image = ImageTk.PhotoImage(Image.open('Image.png') # This is the code line that is maybe causing the problem
label = tk.Label(root, image=image) # Placing the image on the screen
label.image = image
label.place(x=<x>, y=<y>)
root.mainloop()
This script runs perfectly if you have it anywhere but the startup folder, for example, if you have it on your desktop you can successfully run the script.
I have tried to eliminate this problem for the better part of a day but have been unsuccessful.
I have tried changing
ImageTk.PhotoImage(Image.open('Image.png'))
to
file = 'Image.png'
tk.PhotoImage(file=file)
to no avail.
@Hamligt's answer does work, but if the username/startup location is unknown, and the script is placed in the startup folder, you can instead chdir into the script's folder, avoiding hard-coded values, thus making it work on any computer.
import os
os.chdir(os.path.dirname(os.path.realpath(__file__)))
print(os.getcwd()) # correct folder
Why this code works is because without the full path of the image, it is read from the current working directory, which is wrong, so we need to manually correct it back.
