Prevent multiple instances of MdiChild form?

How can I prevent multiple instances of MdiChild form? I have a MdiParent
form with a DataGrid showing all the clients in the database. User clicks on
a row to open MdiChild form which display details of the client. User can
have multiple clients open at the same time, but how can I prevent them from
opening multiple instances of the client?

At least do you need some programma code.
That can be in dotNet by instance C++, C# or VBNet.
