Uploading/downloading registration
I have a program. I want to distribute a passcode so that they
can register the software one-time. The way I currently handle this
is alot of work.
My thought process was this: to create a 100 passcodes like:
14123
45143
34533
just random numbers. I give a number to someone, they type in the
passcode and the software goes to a folder on the web, downloads
an ascii file, removes that number from the list of numbers on that
file, and then uploads that new file to the web. Since that number has
been removed, the passcode was only valid once.
I can download an ascii file from my website, but I can figure out
how to upload that new file to replace the existing file. My question
is twofold:
1. Is my strategy a good strategy for distributing passcodes? Anything
I can do to make it easier.
2. How can I upload a file to replace an existing file on the web?
Please, any response any one can give me will be greatly appreciated.
Sample projects are adored!!

Re: Uploading/downloading registration
Sorry Danielle, but you'll run into the age old problem of "sob stories". I've had this over & over again where a customer registers my s/ware and then calls me a few weeks later to say that their computer broke down and they need a new code.
To add to your strategy I'd do this.... delete the code from the file but transfer it to another file that contains just one code (the last valid code you issued). Each time one of your apps starts up, make it log onto the web site and check that its code is the same as the currently valid one for that customer. That way, if your customer obtains a new code, his old copy will magically stop working.

Re: Uploading/downloading registration
John,
Any chance you have a sample project you can share that would
do this?
I can download a file using a CWebGrab class, but I cant figure out
how to upload it to a specific folder on a server.
Any sample project you can possibly share would be great. My
email address is brinasas@yahoo.com
