Hello, Iam trying to make a program to do something for me. Though I did it in php for linux system, I dont think i can use it in windows.. So its c++ time

I have a folder called "done" when any file goes into done it opens maketorrent and then creates a .torrent file and saves it into a file called "tdone"

Any clue on how to do this :O or even better were to start?

Thanks
squill

This doesn't sound too complex. You should try and break it down into sections.

First, you need code to check if a file exists; this can be done using fstream (Google this, there will be lots of examples).

Next you the have to put this in a loop to keep checking for a file. Inside this loop you can check if the file exists, if it doesn't, sleep for a minute, or however long you want, when the sleep is over it will check again. You will not want the sleep to be too short or it will bog down your system.

Once the file is found you can process it. I am not familiar with MakeTorrent, but if you can call it from command line passing in the file you found as a parameter, it should be pretty easy to call from c++. There are a few options for calling processes from c++; you said you were writing this in Windows, so the win32 function CreateProcess should do the trick.

This is how I would break it down. Hopefully this gets the thought process moving.

Thanks, Seam to hit it on the head..going to do some research, as i was practicing using php threw line command.. anyhow maketorrent can be called but must use MinGW which is kind of new to me.. soo off to do alot of research.. and sure ill have questions later

thanks again
squills


also
i need it to more or less trigger the maketorrent when something new is added as there could be alot of files in this folder all ready, soo when a new file is added it will pass that info to make torrent.. woudl you still suggest using fstream to check?
thanks

What you will have to do is when your program first starts is read in all the files in that directory into a list, then every time you check for a new file, you can read the contents of the directory and compare it to that list to see if there are any new files. I do not think fstream can read the directory to get a list of files, but the boost library can:

You can use the CreateProcess function I mentioned above. Basically it takes the application name as the first param (mktorrent), and then the rest of the parameters you pass in with it. To use this you will probably have to include the windows header file. More information can be found here:
