This example shows how to go directly to the Windows API and not link in the C Standard Library. global _main extern _GetStdHandle@4 extern _WriteFile@20 extern _ExitProcess@4 section .text _main: ; DWORD bytes; mov ebp, esp sub esp, 4 ; hStdOut = GetstdHandle( STD_OUTPUT_HANDLE) push -11 call _GetStdHandle@4 mov ebx, eax ; WriteFile( hstdOut, message, … Read more
Closing a c++ console app with the “x” in the top corner throws an CTRL_CLOSE_EVENT which you could catch and process if you set a control handler using the SetConsoleCtrlHandler function. In there you could override the close functionality and perform whatever you wished to do, and then optionally still perform the default behavior.
You don’t have write any C/JNI code. From Java: import sun.awt.windows.WComponentPeer; public static long getHWnd(Frame f) { return f.getPeer() != null ? ((WComponentPeer) f.getPeer()).getHWnd() : 0; } Caveats: This uses a sun.* package. Obviously this is not public API. But it is unlikely to change (and I think less likely to break than the solutions … Read more
In C/C++ LONG lStyle = GetWindowLong(hwnd, GWL_STYLE); lStyle &= ~(WS_CAPTION | WS_THICKFRAME | WS_MINIMIZEBOX | WS_MAXIMIZEBOX | WS_SYSMENU); SetWindowLong(hwnd, GWL_STYLE, lStyle); WS_CAPTION is defined as (WS_BORDER | WS_DLGFRAME). You can get away with removing just these two styles, since the minimize maximize and sytem menu will disappear when the caption disappears, but it’s best to … Read more
Read the MSDN documentation for the SetClipboardData function. It appears you are missing a few steps and releasing the memory prematurely. First of all, you must call OpenClipboard before you can use SetClipboardData. Secondly, the system takes ownership of the memory passed to the clipboard and it must be unlocked. Also, the memory must be … Read more
x86 does not require alignment for a lock cmpxchg instruction to be atomic. However, alignment is necessary for good performance. This should be no surprise, backward compatibility means that software written with a manual from 14 years ago will still run on today’s processors. Modern CPUs even have a performance counter specifically for split-lock detection … Read more
As quoted from source (Creating the smallest possible PE executable): 1 Smallest possible PE file: 97 bytes Smallest possible PE file on Windows 2000: 133 bytes Smallest PE file that downloads a file over WebDAV and executes it: 133 bytes The files above are the smallest possible PE files due to requirements of the PE … Read more
You need to create a static method to use as the actual thread start function, and pass a pointer to the instance as the lpParameter argument to CreateThread. That will get passed to the static method, which can cast it to an object pointer and call through to the member function. class MyClass { static … Read more
NTFS file system has junction points, I think you may use them instead, You can use python win32 API module for that e.g. import win32file win32file.CreateSymbolicLink(fileSrc, fileTarget, 1) If you do not want to rely on win32API module, you can always use ctypes and directly call CreateSymbolicLink win32 API e.g. import ctypes kdll = ctypes.windll.LoadLibrary(“kernel32.dll”) … Read more
EnumWindows enumerates all the top level windows in a process. GetWindowThreadProcessId gets the process and Id of each thread. You now have enough information to gracefully close any GUI application. You can send WM_CLOSE messages to any window you wish to close. Many windows handle WM_CLOSE to prompt the user to save documents.You can send … Read more
