I'm building an app that given another app mainWindowhandle it collects information about the window state. I have no problem collecting information about child windows, but I can not access the other open windows of an application or even the menus. Is there any way of getting all window handles of an application?
Get the handle of the parent window using the command: String parentWindowHandle = driver. getWindowHandle(); Print the window handle of the parent window. Find the element on the web page using an ID which is an element locator.
The proper way, in my humble opinion, is handle=FindWindowW(NULL, L"Calculator"); (using UNICODE) or handle=FindWindowA(NULL, "Calculator");(using ANSI). Even better, use instead FindWindow macro to avoid know what character set is used in the project, so make your code "agnostic" to character set.
The Win32 API provides no direct method for obtaining the window handle associated with a console application. However, you can obtain the window handle by calling FindWindow() . This function retrieves a window handle based on a class name or window name. Call GetConsoleTitle() to determine the current console title.
You can use EnumWindows and GetWindowThreadProcessId() functions as mentioned in this MSDN article.
You could do what Process.MainWindowHandle
appears to do: use P/Invoke to call the EnumWindows
function, which invokes a callback method for every top-level window in the system.
In your callback, call GetWindowThreadProcessId
, and compare the window's process id with Process.Id
; if the process ids match, add the window handle to a list.
First, you'll have to get the windowhandle of the application's mainwindow.
[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
IntPtr hWnd = (IntPtr)FindWindow(windowName, null);
Then, you can use this handle to get all childwindows:
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool EnumChildWindows(IntPtr hwndParent, EnumWindowsProc lpEnumFunc, IntPtr lParam);
private List<IntPtr> GetChildWindows(IntPtr parent)
{
List<IntPtr> result = new List<IntPtr>();
GCHandle listHandle = GCHandle.Alloc(result);
try
{
EnumWindowProc childProc = new EnumWindowProc(EnumWindow);
EnumChildWindows(parent, childProc, GCHandle.ToIntPtr(listHandle));
}
finally
{
if (listHandle.IsAllocated)
listHandle.Free();
}
return result;
}
