I don't know and never tried (hopefully someone else will help if possible) but as I alluded earlier, this is likely a bad idea. In particular the user could loose his work if you just close his Excel file. Generally your application should deal with what currently happens rather than to impose his own will to the whole system (and ultimately to the user). I would just bypass those files and would process them at a later time. Some more details about what you are doing with them cold perhaps help. -- Patrice

See this VB6 sample: http://vbnet.mvps.org/code/network/netfileenum.htm If it's not on a share, then there is no documented way to get the process that has the file open. The undocumented way is by using SystemHandleInformation() or NtQuerySystemInformation(). Search the web for these for more information, but not using them properly may crash your application and possibly the system.

Hi Nobody. I think it has much option. . it search by machine "NetFileEnum: Get Open File Info from a Specified Machine" subject it self. If I am not mistake this give list of open file on machine. but i need to find User ID, Who has opened That File. I don't' want to loop for 100 computer to find one file. It Gives Owner, as I understand it is the UID of computer where the file is. WELL i am not good for Win API. So I don't know much to manipulate it. i am not sure if there will be API function which give the UID of computer if the file is already open. Like in AutoCAD: for e.g. Server has all files. And computer AAA has open file. And if computer BBB tries to open same file, it give message "AAA has opened file". And you will have option to open file on read-only mode. That's it. Thanks for your effort. I really appreciate it.
