wait while file being written [solved]

[lasaucisse]

hi,

first, excuse my poor english, i'm french

I'm coding un GUI for a tool, whose goal is to automate some actions with this tool, by sendind hotkeys. I have to use the send() function because the WinMenuSelectItem() function fail : no detected menu in my tool with Au3info.exe.

At the end of my hotkeys sequence, I need to save the current file, then to close it.

my problem : for big files, the saving process takes some time (several seconds), so I need to wait before to send the "close" hotkeys. So I need to know how many time I have to wait, so I need to check if the saving process is finished or not.

but I can't find the way to do that !

I tried to checked :

- if the file can be read or write while the process...failed, no error code, I can open in read or write mode, although the file is still being written !

- the file's size : it's change during the save process, but not continuous : I can check if the file's size didn't change since seconds, but I'll have to wait at least 4 or 5 seconds to be sure it's ended : too long !

same limitation with file's timestamps...

- the file's attributes, it's "A" (archive) before, during and after the save process

So... how can I check that a file is being written by any process ?

Take a look at the FileInUse function in my signature. Loop while it returns true to wait until writing has finished.

Edit: I always add a pop-up with a looping progressbar and a timer check to the loop to set a certain timeout value.
