[RESOLVED] Unicode file name from OLEDrop data.Files

Hi

I'm trying to drop files with unicode names into my app but it seems to fail.
A function that gets the last edit date using CreateFileW+GetFileTime works fine when I pass the path and file from other sources (like my codejock open file dialog) But when the path and file name variable is set from the data.Files array (variant) it fails since CreateFileW returns -1. I suspect the vb6 OLEDrop.Files collection does not contain the proper unicode filenames. Can anybody confirm this and suggest a workaround. One strange thing is that DIR (used to verify that the file exists) returns correctly from both sources...

plz give code

Hi

I have so far confirmed that the code (below) works fine to get the date from a string both ansi and unicode. I have also confirmed that the problem is that the string I get from the DataObjectFiles collection of the OLEDrop event does NOT contain the unicode characters. The debug.print in the function returns 63 (questionmark) if it is the DataObjects.Files string while it returns 22030 if the strings comes from my fileopen common dialog code. The file name is:
嘎伽嘎ㅈ퓨_2008-03-04_18-17-54.JPG
and starts at character 31 after the path. I use the same file for both the open file dialog and my OLE draganddrop operation.
The DIR strangeness was simply explained by that the questionmarks that replaces the unicode characters in my string were treated as wildcards by DIR and the file was therefore "found".
So I think this comes down to: How can we get the unicode file names from the OLE data structure?
A screenshot in this article sort of indicates there are two files collections in the actual object but I guess vb6 only gives us the non-W files collection...

Sorry did not have time to try this until now but that worked perfectly. Thanks DrUniCode (and LaVolpe)!
