Hi guys,
Ive got an annoying problem, I cant append any text to the text file. Every time I open it for writing, I overwrite the data. I tried to move the file pointer to the end of the file, but no result (no writing to the file at all). Here is the code:
INVOKE CreateFile, offset filePath, GENERIC_WRITE, FILE_SHARE_WRITE, 0, OPEN_ALWAYS,FILE_ATTRIBUTE_NORMAL,0
mov hFile, eax
mov edx, 10
INVOKE SetFilePointer, hFile, 0, 0, FILE_END
INVOKE WriteFile, hFile, offset buffer, edx, ADDR SizeReadWrite, NULL
INVOKE CloseHandle, hFile
Any ideas? Thank you in advance!
