how have button generate number 0-255 (randomly) force display textbox in form field? make counts times have clicked button , have force text textbox?

also how force textbox can input number 0-255.

another question when "application.restart()" how force display top application (over other programs running.) on reload.

for first value, use numericupdown instead of textbox. restrict integer values , allow specify minimum value (0) , maximum value (255). button can make use of random class , simple counter variable. display number of clicks in label value isn't meant changed user:

public class form1      private sub form1_load(sender object, e system.eventargs) handles me.load         numericupdown1.minimum = 0         numericupdown1.maximum = 255         label1.text = "clicks: 0"     end sub      private sub button1_click(sender system.object, e system.eventargs) handles button1.click         static r new random         static counter integer = 0         numericupdown1.value = r.next(numericupdown1.maximum + 1)         counter = counter + 1         label1.text = "clicks: " & counter     end sub  end class
