Pywin32 Movefileex

[shanenin]

Inspired by Matt's project i was seeing if I could use python to delete a file upon reboot. I am only able to rename it at reboot, I can't figure out the syntax to set the destination to null. Below is what works to rename the file

import win32file
import win32api

win32file.MoveFileEx("test.txt", "test2.txt" , win32file.MOVEFILE_DELAY_UNTIL_REBOOT)

how can I set the destination to null, to delete upon reboot?

[jcl]

win32file.MoveFileEx("...", None, win32file.MOVEFILE_DELAY_UNTIL_REBOOT)

I tried None without quotes, but it would not let me do it

C:/Python24/pythonw.exe -u  "C:/Documents and Settings/shane/Desktop/deletereboot.py"
Traceback (most recent call last):
  File "C:/Documents and Settings/shane/Desktop/deletereboot.py", line 4, in ?
	win32file.MoveFileEx("C:/Documents and Settings/shane/Desktop/test.txt", None , win32file.MOVEFILE_DELAY_UNTIL_REBOOT)
TypeError: None is not a valid string in this context

[jcl]

Gah, I was looking at the ActivePython win32api.MoveFileEx.

Gah, I was looking at the ActivePython win32api.MoveFileEx.

I was also using that for a reference, is it incorrect?

Can null be used as an argument somehow?

XP?

This is how its done in VB I believe:

MoveFileEx(szSrcFile, szDstFile, MOVEFILE_DELAY_UNTIL_REBOOT);

Example:

MoveFileEx( "C:\killme.exe", NULL, MOVEFILE_DELAY_UNTIL_REBOOT );

[shanenin]

the above code works with VB, I am trying to use python to call MoveFileEx. To be honest I do not really understand how vb works. Does it need to be compiled?

[Matt]

I don't know VB either. It does need to be compiled. Did you try NULL in the python script?

[shanenin]

I tried it, among any other possible variation.

Use the win32api version of the function instead.

Incidentally, VB.NET is pretty much C# with different syntax and slightly different features. It's compiled to CIL bytecode and then JIT/AOT compiled to native by the .NET runtime.

Use the win32api version of the function instead.

I am not following you. Isn't that what I am using?

[jcl]

You used the win32file version in the code you posted. win32api and win32file export different MoveFileEx functions. I have no idea why.

[shanenin]

I thnk I need to be spoon fed. Can you show me how you would code that?

huh?

import win32api
win32api.MoveFileEx()

[jcl]

win32api.MoveFileEx("file", None, win32con.MOVEFILE_DELAY_UNTIL_REBOOT)

Thanks :-)
