disable minimize/maximize and restore button on mdi child form. But need Close button to be active.

Question

I want to disable the min/max/restore button of my mdichild form. For that I have set MaximizeBox=false and MinimizeBox=false borderstyle=resizable and my form opens in Normal state. Now the problem is minimize button is disabled but it shows a restore button i want this restore button also to be disabled. Any way to do this? i don't want to use controlbox = false because i still need the close button.

Hi Kirtan.. thanks for your help. But there is one more criateria.. I am opening multiple child forms in a single MDI form and at any given point of time only one form needs to be active. With the code you provided..user is able to move or shift the form to see the form in the background..and can start working on it.. Is ther any way to have only close button to child form and it is sort of docked inside the parent form. so that it can not be moved... e.g if you set borderstyle to Sizble and window state to normal.. I want the form to appear like this..but only with Close button..
