FileGetSize() problem

[Guest]

Hello.

I want to check the size of a particular file that still creating.

For doing this, I'm using FileGetSize() in a while loop..

But there is a problem. It turns out that the function is not updated with the new size of the file (while it is still written)

I do not know what to do ..

What I want to do is to know if the file continues to be written. If not then know that it happens.

I can not do this because of this problem the function ..

Hi,

If the file is still opened by another application for writing while you want to get its size, I'd say it's normal that it does not work.

Since the native FileGetSize function does not support a file handle, you will have to use the WinAPI functions.

Edit: Forget my last sentense if it's for another app.

Br, FireFox.

Have you tried looking at the _WinAPI functions?

Other possibilities: you could keep track of the size of what you put into the file, that would be my preferred solution, or you could also close the file every few loops, check the file size, then reopen it for append, though that would slow things down some.

If you are trying to get the converting media size (according to your previous topic), then wait for the file to exist before using the _WinAPI_CreateFile function.

Use the _WinAPI_GetFileSizeEx func in the loop and _WinAPI_CloseHandle func after the loop.

Try this :

#include <FileConstants.au3>

Local Const $OPEN_EXISTING = 2

Local Const $hFile = _WinAPI_CreateFile("myfile.txt", $OPEN_EXISTING, $GENERIC_READ, BitOR($FILE_SHARE_READ, $FILE_SHARE_WRITE))
ConsoleWrite("Size: " & _WinAPI_GetFileSizeEx($hFile) & @CrLf)
_WinAPI_CloseHandle($hFile)

To add to what FireFox said, look at Lock UDF in my signature for examples of using the WinAPI functions.

Thank you!
