At the top of the page you will see a box labelled Search. Type single instance into this box. Select Articles / Quick Answers in the dropdown next to it. Click the Go! button.

But it seems you are a child asking others to search for you.

People come here only if they do not find the information through search engines. Google gave me 1,76,000 results for "C# Single instance", the top two of which are CP articles. If you had even tried this, you wouldn't have posted this question here.

This problem sent me on various run arounds... the best solution (by far) that I found was: http://dotnetperls.com/single-instance-windows-form[^]

Try using Mutex for inter process communication it is best and as easy as needs only 3 lines of code :)

[joelwms]

This article (A Single Instance Application which Minimizes to the System Tray when Closed) has information on making single instance forms in C# using mutex.

I have done it. Thanks for all :)
