Welcome to the forums.

Actually, you can use DeleteFile, but need to use the Unicode version: DeleteFileW
Notice the parameter is different and so is how it is passed

Code:

---

Private Declare Function DeleteFileW Lib "kernel32.dll" (ByVal lpFileName As Long) As Long

Sample call: lResult = DeleteFileW(StrPtr(sFileName))

---

sFileName is a string that contains the unicode file name.

Use the UniCode version of the API

Declare Function DeleteFile Lib "kernel32" Alias "DeleteFileW" (ByVal lpFileName As Long) As Long

Then use stringPointer to point to the file.

DeleteFile strPtr("D:\?-Tö+")

DeleteFile strPtr("D:\?-Tö+")

thanks 4 the answer guys ... but,

there's no error message for this function, but ... the file is still exist in my D:\ Drive, is there any problem how to write the code ?

actuallly, in windows explorer filename not "?-Tö+", but it's like just a square ...

How are you getting the file name? I doubt you want to hardcode it. Unless your regional settings are the foreign language, VB's Dir() should not return valid results, neither will a FileListBox. You will want to look at using more APIs to get the file name, depending on how you are getting that name to start with.

You cannot type unicode text into the code window but you can create unicode text in various ways, such as using a byte array then applying StrConv() to that array to return a unicode string that can be passed to unicode version APIs.

i just use 'alt' button and press numeric keyboard,, and so, what should i do now ? to delete the unicode filename ?

Mozzart....

What LaVolpe is asking is, HOW you are telling VB that the File is there?

Through a list box ? or is it typed in directly in the IDE?

Also that filename doesn't seem to have a file extension! Not that i think is an invalid thing to do, but you might want to make sure the file exists before your use the DeleteFile api.

oh, i'm sorry, my english translate is really bad .. :(

i get the filename from .... common dialog controls ... for the filename that doesn't have any extension, it's ok right ?

ok.. in that case you should use the CommonDialog APi to be able pass the Unicode Filename, otherwise the default CommonDialog wouldn't return the correct path.
