The FILECOPY command - Tillmann Viefhaus - 06-15-2025
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?

What does ERR say? This might give a clue.

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 functionThe 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 ''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.
