MSDN states: Interprocess Communication Between 32-bit and 64-bit Applications 64-bit versions of Windows use 32-bit handles for interoperability. When sharing a handle between 32-bit and 64-bit applications, only the lower 32 bits are significant, so it is safe to truncate the handle (when passing it from 64-bit to 32-bit) or sign-extend the handle (when passing … Read more
Use LoadLibrary and NtQueryKey exported function as in the following code snippet. #include <windows.h> #include <string> typedef LONG NTSTATUS; #ifndef STATUS_SUCCESS #define STATUS_SUCCESS ((NTSTATUS)0x00000000L) #endif #ifndef STATUS_BUFFER_TOO_SMALL #define STATUS_BUFFER_TOO_SMALL ((NTSTATUS)0xC0000023L) #endif std::wstring GetKeyPathFromKKEY(HKEY key) { std::wstring keyPath; if (key != NULL) { HMODULE dll = LoadLibrary(L”ntdll.dll”); if (dll != NULL) { typedef DWORD (__stdcall *NtQueryKeyType)( … Read more
Well, instead of passing Application.Current.MainWindow, just pass a reference to whichever window it is you want: new WindowInteropHelper(this).Handle and so on.
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.
You can add the following to the AndroidManifest.xml file inside the activity that has to open the file (pdf in our case) <intent-filter > <action android:name=”android.intent.action.VIEW” /> <category android:name=”android.intent.category.DEFAULT” /> <data android:mimeType=”application/pdf” /> </intent-filter> Make sure you specify the proper mime format. The user will be prompted to choose your app if she wants to … Read more
It’s an abstract reference value to a resource, often memory or an open file, or a pipe. Properly, in Windows, (and generally in computing) a handle is an abstraction which hides a real memory address from the API user, allowing the system to reorganize physical memory transparently to the program. Resolving a handle into a … Read more
