The FILECOPY command

[Tillmann Viefhaus]

When I write:

CHDR "D:\Test_with_Files"

A = "Original.exe"
B = "Original_Copy.exe"
Filecopy A, B

A is existing on the harddrive but File B is not created. Why is that?

CHDR "D:\Test_with_Files"

A = "Original.exe"
B = "Original_Copy.exe"
Filecopy A, B

What does ERR say? This might give a clue.

There is no ERR message. And thats whats suspicious. The command just doesn't work. Or does it write the new file elsewhere on the drive?

I found the error. I just had the wrong filename which was the one of the program I was working with. The file A used in FILECOPY must never contain the name or parts of the name of a programm which is just running.

No. The running program only has a write lock applied. I still can be read – what PB's filecopy is doing.

I just have tested it:

Code:

#compile exe
#dim all

function pbmain () as long
    local sFileA as string
    local sFileB as string
    sFileA = "test.exe"    ' This running program
    sFileB = "copy_of_test.exe"
    filecopy sFileA,sFileB
    if err then
       stderr str$(err)+": "+error$(err)
    end if
    if isfile(sFileB)=0 then
       stderr "Filecopy did not succeed."
    end if
end function

The filecopy is doing fine.

'Question is in PowerBASIC for Windows section, so changed Albert's code
'to PBWin from PBCC.
'
'I was curious if FileA is itself the running EXE containing FILECOPY.
'But that works fine also. (see #COMPILE line)
'

Code:

#compile exe "test.exe"
#dim all
'
function pbmain () as long
    local sFileA as string
    local sFileB as string
    sFileA = "test.exe"    ' This running program
    sFileB = "copy_of_test.exe"
    filecopy sFileA,sFileB
    if err then
      'stderr str$(err)+": "+error$(err)
      ? str$(err)+": "+error$(err)
    end if
    if isfile(sFileB)=0 then
      'stderr "Filecopy did not succeed."
      ? "Filecopy did not succeed."
    end if
    ? "done"
end function '

'that leaves CHDR "D:\Test_with_Files"
'1. is the program that is doing the FILECOPY in D:\Test_with_Files ?
'2. if FileA is not in D:\Test_with_Files it will not be found by FILECOPY.
'
'code in post 1 had no error checking and PB does not display "messages"
'unless asked.
