messagebox display in taskbar

//Rahamath
                                    this.btnAddRecord.Location = new System.Drawing.Point(416, 304);


this.btnEditAuthenticate.Location = new System.Drawing.Point(252, 304)

I my winform application after the form loads it will populate a message box using thread for user input (Ok/Cancel). It is working fine. The problem is the message box directly loaded in the taskbar so the user has to click that tab from the panel to see the message box in the center screen. The new user may not aware of that the appliation need a user input.

I want to show the message box in the center screen instead in the taskbar how can i do this? and what is the problem.
