Hi
i have developed a vb.net software that runs without installing. the file is .cab file.my intention is to save the software on server so that client machines can create a shortcut and get it run without installing it.
But i want it be called from a web form i.e develop an asp.net web form,put a button on it so that when i click the button,it calls the login form for that specified file. i understand that that requires a link to where the file is but dont know how to do it.
Anybody with an idea?
please include steps and possible codes involved.
Thank you
