I'm trying to do the following in Visual Basic.
I open a file, do some processing, close the file and then try to
delete the file. (See code below)

   iFile = FreeFile
    Open sFileName For Binary Access Read As #iFile
    lFileLen = LOF(iFile)

    ....

    Close #iFile

    'DoEvents

    Kill sFileName

    'Set oSys = CreateObject("Scripting.FileSystemObject")
    'oSys.DeleteFile sFileName, True
    'Set oSys = Nothing

When I try to delete the file with the Kill statement, the following
error is raised:
Err Number: 55. Err Desc: File already open.

I've also tried deleting the file with the FileSystemObject, but I get
the following error:
Err Number: 53. Err Desc: File not found

Can anyone help?

Does this work ?

Dim iFile as Integer
Dim lLen As Long
iFile = FreeFile
Open "c:\delme.bin" For Binary Access Read As #iFile
        lLen = Lof(iFile)
Close #iFile
Kill "C:\delme.bin"                  

What about the code between Open and Close ? Do you by any chance
overwrite sFileName or call another function passing the file handle ?
