"Copy File" lock the "Thumbs.db"

[Yaniv Bouhadana]

Hello!

I used the "Copy file" for copying an image file from a directory and everything runs OK, exept one problem - after closing the vi (and even LabVIEW) the "Thumbs.db" file which inside the folder stays "locked" - no rename ,move or deletion of this folder by windows is allowed!

I know it make no sense but still this file stay locked!

It released again when I copy another file from other directory and then the previous "Thumbs.db" file released.

Did someone met this problem?

LabVIEW is known to be a little greedy when it comes to file locks. For example: Cannot move or delete folder while LabVIEW is open.

I use the utility Unlocker for deal with locking issues in general. As usual, the wise rolfk presents a Windows API-based solution using SetCurrentDirectory(), if you're up for it.

OK - I tried both solutions - the Unlocker is ok but its not a solution for a program which i develope to someone else use..

the other solution is nice - I implemented it and the only disadvantage of this solution is that for unlocking one folder you need to lock other and in this case i choose c:\windows - but it means that each time you use a common dialog file box in you program - the deafaut location will be c:\windows...

Thanks again!

Thanks for uploading the code! I'm glad you found something that worked, I'll store that away in case I need it someday.

One workaround to the issue you mention is to do what was recommended in the thread I linked - store your actual working directory yourself and then use the API call before/after dialog calls to make everything place nice.

I'll try it, but I'm afraid that the action of choosing a working directory itself, makes the directory to be locked. I'll try it when I'll have time and report as well.. Thanks again for the reference.
