window-handles

I have webpage which open new browser window on click. I am able to get 2 handles however driver.close() always closes the first/main window. from selenium import webdriver import time driver = webdriver.Chrome() driver.get("file:///D:/blackhole/print.html") han = driver.window_handles print("handles:", han) # gets 1 handle time.sleep(2) click_btn = driver.find_element_by_link_text('Print') click_btn.click() han = driver.window_handles print("handles:", han) # gets 2 handles driver.switch_to_window = han[1] # first element is always first window handle driver.close() # main window close Below

I need to show diagrams of some networks, but the problem is that close all doesn't close these windows, so I have several windows to close manually after a few runs. [x,t] = house_dataset; net1 = newff(x, t, [5, 3]); view(net1); net2 = newff(x, t, [7, 5]); view(net2); close all; However if I keep the handle of window, close function will close it: net3 = newff(x, t, [9, 7]); h = view(net3); close(h); But it's not easy for me to collect all those handles. How can I find all those handles programmatically? You can use the command: nnet.guis.closeAllViews() This will close all the diagrams for

I am thinking if there are handles of the same value ? To clarify my question, let's say I open Notepad, type in some text, save it and then close Notepad. If I repeat this a thousand times (or even more), will I ever have a chance to see the same window handle (HWND) value being used for the Notepad main window that was used the first time? If so, why? ybungalobill By the pigeonhole principal , yes, they can't be unique. In fact, Microsoft still maintains compatibility with 16-bit Windows, and as a result handles are 16-bit values. So there are at most 65536 possible handle values. Yes. There

A window handle sometimes of type int and other times of type IntPtr int example: [DllImport("user32.dll")] static extern uint GetWindowThreadProcessId(int hWnd, int ProcessId); IntPtr example: [DllImport("user32.dll", CharSet = CharSet.Auto)] static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, int wParam, StringBuilder lParam); I don't seem to be able to convert/cast from one to the other. When I try this.ProcessID = GetWindowThreadProcessId(windowHandle.ToInt32(),0) I get an error cannot implicitly convert from uint to int The SendMessage signature is static extern IntPtr SendMessage
