| Disable X in control box, but not Minimizebox (3 replies) |
| microsoft.public.dotnet.languages.vb |

I don't want to disable the whole controlbox, I want the Minimizebox but not the close. I don't want the operator to terminate the window (dispose), I control the close methodology via File Close (using Hide). Thanks |
