Open default browser and send an HTTP request (POST Method)

I'm writing a Windows application and I need to open the system's default browser and post data to Web.

How can I do it? I know I could write a temporarily HTML file with a form that submits just after loading, but I think this way isn't much elegant and besides I have to write and delete temp files constinously. Is there another way of doing this?

Opening a browser seems like a clumsy way to do this.

There are some good APIs for internet access. Try HttpSendRequest on MSDN

Thanks for your answer but I really needs to open a browser because the rest of the application is going to happen within a browser. The problem is that I don't want to open a browser and just point it to an URL, I want to post some data, from the browser.

Honestly, I'd look into doing some sort of socket thing and making a "mini-browser", but if you really need to open it and input data, I'd look into which browser you wanted to use and work out exactly how to interact with that browser. I suppose you could be lazy and work out a series of tab's and key presses to inut data, but I would strongly recommend you don't.

I'm sure there are DLL's or libraries you can use to interact with certain programs, but it might be a bit tricky
