please can someone tell me how to append data to a text file.not overwriting the content
for that
i'v tried to open file like following,
invoke CreateFile,FileName, FILE_APPEND_DATA,FILE_SHARE_READ,NULL,\
OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0

but fasm has given following error

undefine symbol
pushd FILE_APPEND_DATA



>I,m attaching the whole .asm file

Use CreateFile with OPEN_ALWAYS
Then SetFilePointer,[handle],0,0,FILE_END
Then WriteFile,[handle],...

In addition: FILE_SHARE_READ alone will not allow to append, because appending is actually writing!

hey Thank you very much guys for quick and clear responses.I'v got the point.
can any one of you direct me to a good windows assembly(proberbly with FASM)tutorial?
Thanx again.

Only GENERIC_READ and GENERIC_WRITE affect the applications ability to write. Sharing options affect only other handles access to the file.

for windows, the best asm tutorials are the iczelion's, but they are in masm.

there is somewhere in the web, the fasm translation, but I don't thing you will have much problems translating masm to fasm, the important thing are the api calls.

thanx,
sorry to ask another one,
Is there a way of search a sring in a text file using windows API?
