Hi,
I am using WinAppDriver release 1.2 on a Classic Windows application using Java. Since my Windows application has a splash screen, I wanted to add the Attach to existing Window functionality so I could start building my test scripts on the attached window more rapidly.
Here is the application login window details on using inspect.exe

My problem is this with the code I am writing below to attach to this:
DesiredCapabilities desktopCapabilities = new DesiredCapabilities();
desktopCapabilities.setCapability("platformName", "Windows");
desktopCapabilities.setCapability("app", "Root");
desktopCapabilities.setCapability("deviceName", "WindowsPC");
desktopCapabilities.setCapability("ms:experimental-webdriver", true);
WindowsDriver<WindowsElement> windowsDriver = new WindowsDriver<WindowsElement>(new URL("http://127.0.0.1:4723"), desktopCapabilities);
WebElement appWindow = windowsDriver.findElementByXPath("//Window[@Name='logon'][@ClassName='#32770']/TitleBar[@AutomationId='TitleBar']");
String appWindowHandle = appWindow.getAttribute("NativeWindowHandle");
Since the inspect does not have NativeWindowHandle, I am getting the value of this as 0. Hence, this does not allow me to attach to my application. This is the header of that Window, so if I try to use some other Windows Element in that login page, even though it provides some Native Window Handle, it is not the top level window, and hence the converted Hex based Window Handle does not work out for any other element when used instead of the Title Bar element.
However, I tried one thing, I directly copied the hwnd from inspect output above - 0x000000000023187E, and used that hardcoded hwnd to attach. Then it worked fine:
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("deviceName", "WindowsPC");
capabilities.setCapability("appTopLevelWindow", "**0x000000000023187E**");
windowsDriver = new WindowsDriver<WindowsElement>(new URL("http://127.0.0.1:4723"), capabilities);
windowsDriver.findElement(By.name("Connect")).click();
But I am not able to figure out how I can get the value of this hwnd property since NativeWindowHandle of my top level window is not defined in inspect, and always returns a 0 when accessed through code.
Other thing I noted in inspect.exe is "ProcessId". I noted that "ProcessId" property is the same for all inspected elements, so I thought there must be some way to figure out the window handle from process id in Java. But I am unable to find one.
Have the following questions:
- Is there a way to access hwnd property through Java for my element (as shown in the How Found section of inspect.exe), and use that to attach each time my test runs?
- If the above is not possible, is there a way in Java that I could use the ProcessId I grabbed from inspect using getAttribute, and then reverse look up the Window Handle or hwnd based on fetched ProcessId?
- Any other way you could recommend for attaching when the top level window does not have a NativeWindowHandle property in inspect?
Anything which works should help.
Any help would be greatly appreciated on this. Please let me know if there is any information needed from my side.
Thanks,
