CS411 Assignment No, 3 Discussion and Solution. Due date is 30 July Spring 2018

You are required to create a WPF C# application using Visual Studio.

Problem Statement:


Create a grid Layout with one Column and two rows

  • Inside first row create another grid with two columns and two rows and then add 4 buttons. Start First ,Stop First, Start Second and Stop Second. Make the border of this layout Green.
  • Inside second row create a DockPanel and add 4 vertical[1] progress bars. Border must be red.


Pressing Start first Button will increment first two progress bars so that second progress bar is incremented faster and upon reaching 100 the first progress bar is incremented by 1.

So the second progress bar will be completed 100 times and first one only 1 time[2]. But the UI should remain responsive[3] in between this process.

Stop button will stop the process and enable the start button to start process again.

Start Second will do the same to third and fourth progress bars but both the process should work in parallel.
