Gets the current process (program) main form handle and sets the parent form of WPF for this handle

Source: Gets the current process (program) main form handle and sets the parent form of WPF for this handle

Sometimes WPF controls want to display the form themselves, but need to set the Owner property when calling WPF controls in C + +. The roundabout workaround is to set the parent form of the WPF window form to the handle of the process.

1. Get the current process ID

int id = process.getcurrentprocess (). Id;

2. Get the process master handle based on the process ID

 public static class Processhelper {private static class Win32 {internal con                St UINT Gwowner = 4;                Internal delegate bool Enumwindowsproc (IntPtr hWnd, IntPtr lParam); [DllImport ("User32.dll", CharSet = CharSet.Auto)] internal static extern bool EnumWindows (Enumwindowsproc l                Penumfunc, IntPtr LParam); [DllImport ("User32.dll", CharSet = CharSet.Auto)] internal static extern int GetWindowThreadProcessId (INTPT                R HWnd, out IntPtr lpdwprocessid);  [DllImport ("User32.dll", CharSet = CharSet.Auto)] internal static extern IntPtr GetWindow (IntPtr hWnd, uint                Ucmd);             [DllImport ("User32.dll", CharSet = CharSet.Auto)] internal static extern bool IsWindowVisible (IntPtr hWnd); } public static IntPtr getprocesshandle (int processId) {IntPtr PROCESSPT                R = IntPtr.Zero; WiN32.                    EnumWindows (hWnd, LParam) = {IntPtr pid;                    Win32.getwindowthreadprocessid (hWnd, out PID); if (pid = = LParam && win32.iswindowvisible (hWnd) && win32.ge                        Twindow (hwnd, win32.gwowner) = = IntPtr.Zero) {processptr = hwnd;                    return false;                } return true;                }, New IntPtr (processId));            return processptr; }        }

3. Set WPF window's parent form to the current Process main window handle, complete with the following code:

  int id = process.getcurrentprocess (). Id;            IntPtr mainptr = processhelper.getprocesshandle (ID);            var win = new Window ();            New Windowinterophelper (Win) {Owner = mainptr};             Win. Show ();
