I'm trying to use sequential binary file editing in C++. I use a temporary file. I have to make the changes in the file by storing the modified data in the temp file. Then I delete the original file and rename the temp as the original. The problem is the remove() and rename() functions in <fstream.h> don't seem to be working. When I check in the folder after execution, the temp file is still there and so is the original file. Does any1 know an alternative method to remove and rename a file during runtime?

Do you have a code sample that demonstrates the problem? Are you checking return values?

I didn't know I had to close all variables connected to the file to be deleted. It worked after I did that. Thanks a ton Dave. :)
