I would like a windows application that is able to run without any problems within xp and vista - that looks like a normal setup program (you know those click next to continue types) Behind the scenes without the user knowing, it should download a file from my server that contains information. And then using that information it should open a hidden browser and use it to fill the form which is contained in the url and click submit. Preferable 3 hidden windows should be opened at a time. Judging by the information provided in the file that was downloaded from my server - it should wait for the second page to load and fill that page as well. Sometimes this will be required - other times it will not be. I reserve full ownership rights to the source files. *Which will be sent to me as well*
