Hi,
i want only the source-code for a function like this "copyfile" to "target".
The copied file should become at the same time a new name

Example:
Copy File C:\programmes\bla\xy.exe to C:\programmes\renamedfile.exe

Not more guys Smile

When i have the code i compile it and put this code to an executable with a hexeditor. I change then the OEP etc. ...but that can I make.

regards,
XY2k

Call label1
 db "C:\programmes\renamedfile.exe ",0
label1:
Call label2
 db "C:\programmes\bla\xy.exe",0
label2:
Call [CopyFile]

Sorry it doesn´t work

Code:

BOOL CopyFile( 

LPCTSTR lpExistingFileName,
LPCTSTR lpNewFileName, 
BOOL bFailIfExists 
);

push 0 
Call label1 
 db "C:\programmes\renamedfile.exe ",0 
label1: 
Call label2 
 db "C:\programmes\bla\xy.exe",0 
label2: 
Call [CopyFile]

by compiling with cmd it say :
copy.asm[1]
BOOL CopyFile(
error invalid expression

And when i want only compile the second code:

Code:

push 0
Call label1 
 db "C:\programmes\renamedfile.exe ",0 
label1: 
Call label2 
 db "C:\programmes\bla\xy.exe",0 
label2: 
Call [CopyFile]

It say: --> Call [CopyFile] "is undefined symbol"

Crying or Very sad

you need to do put it in a PE executable.

Code:

include 'win32ax.inc' 
format PE console 4.0
.data
label2 db 'C:\blah\blah.blah',0
label1 db 'C:\from.exe',0
.code
start:
invoke CopyFile, label1, label2, 0
invoke ExitProcess,0
.end start

Edit: attached code that will process the command line
it goes like this: cp FromFile ToFile

I got this error when use CopyFile Win32 API...... Is it not in Kernel32.dll, what does the error mean?

C:\Users\BOO\Projects>sfc /scanfile=c:\windows\system32\kernel32.dll

It means your source file is corrupted in some way.

Finally I found out why, because the correct API is "CopyFileA", not "CopyFile", but strange, both can compile without error.

The name matching is done at runtime. You can put any text you want for API names and it won't fail until you try to run it.
