Pass arguments to running application

Question

I am making an image uploader (upload image to image hosting website) and I\'m having some issues passing an argument (image location to an already running application)

Answer 1

Well you will have to establish a communication channel for other applications to post the images to. This communication channel can be one of the following - not a complete list just samples:

• A directory that is watched by your app and the file is added once it is added to the directory.
• A port where other applications can send information to.
• A self-hosted web service that accepts the images.
• A TCP port that receives the images.
• A named pipe.
• ....

As you see there are several possibilities. The right one for you depends on your scenario. The file system is an option that can be implemented easily using a FileSystemWatcher for a sample see here.

A self-hosted web sevice exposes a web service that can receive images. See here for a sample.

IMHO, these are the two options that are easiest. But ... there are several more.

For the TCP port see Tim's post.
