Using a timer to wait for processes to complete

Question

Imagine there are two buttons that call an asynchronous function

  int packProcesses=0;  //the number of processes we are dealing with
    bool busy = false;  //         


        

Answer 1

if you can at all, I would try and avoid having your button6_Click and button5_Click methods returning void. if instead you have them return a Task you can await them.

private async Task button5_Click(object sender, EventArgs e) 
{ ... }

private async Task button8_Click(object sender, EventArgs e) 
{
     await button5_Click(sender, e);
     await button6_Click(sender, e);
}

edit:

private async Task HandleButton5_Click() 
{
     ...
}    

private async void button5_Click(object sender, EventArgs e) 
{  
    await HandleButton5_Click();
}

private async void button8_Click(object sender, EventArgs e) 
{
     button5_Click(sender, e);
     button6_Click(sender, e);
}
