[Balagurunathan S]

Dear Friends.. I am having login screen form in my VB.Net windows application.I should be able to display that form only once in my PC.i.e i want to restrict multiple opening of the same login form. I mean that only one instance of that form should be viewed in the screen. Someone help in this regard as early as possible.. Regards,

You can set a time limit when you're paying someone. Do you mean you want your app to show only one login, or that you only want one instance of the app to run ? The former is entirely up to how you write the code, the latter, you can do a number of ways. Interestingly. when I did what all people in a hurry should do (try google), the first two hits were articles on this very site. Did you think to search the site or try google ? http://www.google.com.au/search?sourceid=navclient&ie=UTF-8&rlz=1T4ADBS_enAU225AU226&q=vb%2enet+%22single+instance%22[^]
