I decided to check that my batch file exists.
GetFileAttributes worked fine when run by itself in a simpler program.
I loaded the program below in Olly, ran it, and inserted a thumbdrive.
It said the file was not present when it was.
I could not see that anything changed in Olly.
Is there a certain way I have to load my program in it ?

not sure you need the GetMessage loop thingy
anyways....
invoke GetFileAttributes, addr FileName

jmp FileNotExist

you will get the "not exist" message box if the file does not exist
you will also get it if there is an error creating the process
why not...
invoke GetFileAttributes, addr FileName
.if eax==0FFFFFFFFh
invoke MessageBox, NULL, addr Error, addr szAppName,MB_OK
.else
fn CreateProcess,0,OFFSET szCmd,0,0,0,CREATE_NEW_CONSOLE,0,0,ADDR sui,ADDR pi
.if EAX == 0
invoke MessageBox, NULL, addr szError, addr szAppName,MB_OK
.endif

invoke GetMessage,ADDR msg,0,0,0 ; you get the message into MSG and then???
.endw
; dead code ;-)
invoke ExitProcess,0

i guess i see that now
that's a strange way to do things - lol
it may as well be
label0: jmp label0
just create a dialog box with a button in it :biggrin:
Did not MASM already have it? Are you going to make it your own?
qWord,
Thanks for pointing out that I had code not being used.
