How to create a program that will replace a file?

[cudzich09]

So I want to create a program that will replace a file. I dont know how to do that, I looked around with google but could only find something like visual patch or patch maker. Is this the program that I should be using to create patches?


I only want to replace an old file (sample.exe) with the new file(sample.exe). I want to create a program that will do it automatically.


Thanks

First, a couple of questions. What language do you want to use? Are you familiar with any? Is the file going to be in the same place on every computer?

So a patch program is probably more than you need for your simple task. It boils down to a set of operations. 1) check the version of the existing file; 2) copy it if it needs to be replaced.

You can do this in any programming language, including cmd shell script, depending on how you define "need to be replaced." It might be a simple date/time check, or it might involve checking the version number in the executable file.

So what do you need to check to know whether the file should be replaced? We can take it from there.

The nullsoft installer can create programs to do software installations or like you want, just copy over a file:

Just a guess, but I'm thinking that the OP wants to have an update mechanism like Firefox.

install shield or windows installer packages?
