是否可以全局挂接窗口的创建,以便我可以控制窗口在屏幕上的放置位置? [英] Is it possible to hook the creation of windows globally so I can control where the windows are placed on the screen?
问题描述
我可以将钩子插入正在运行的进程中,以捕获它们创建,销毁时的最大值/最小值.但是我还没有想出一种方法来赶上新流程的创建,因此我无法将自己的想法注入其中.有谁知道实现此目标的最佳方法?
I can inject a hook into running processes to catch when they create, destroy, max/min. But I haven't come up with a way to catch the creation of a new process so that I can inject my hook into that one. Does anyone know the best way to accomplish this?
推荐答案
SetWindowsHookEx 是您最简单的解决方案.
SetWindowsHookEx is your easiest solution.
如果您不介意安装防病毒软件,则还可以将DLL注入每个进程,然后将它们钩住CreateProcess(将DLL注入其他进程)和CreateWindowEx(出于您的目的).
If you don't mind upsetting the anti-virus software, you can also inject a DLL into each process that will then hook CreateProcess (to inject the DLL into further processes) and CreateWindowEx (for your purposes).
我只是完整地阅读了您的问题.是的,您只需要钩上CreateProcessW并将钩子注入到将来的进程中即可.
I just read your question completely. Yes, you'll want to just hook CreateProcessW and inject your hook into future processes.
编辑#2:昨天我实际上正在做类似这样的事情,所以有一些代码可以满足您的需求.
EDIT #2: I was actually working on something like this yesterday, so some code which does what you want.
#include <windows.h>
// call GetModuleFileNameto get the full path of the module before installing the hook
static LPWSTR lpszDllName;
HMODULE LoadModuleEx(__in HANDLE hProcess, __in_z LPCTSTR lpcszDll)
{
DWORD cdwSize;
LPVOID lpvAllocation;
HANDLE hThread;
HMODULE hRet;
cdwSize = lstrlen(lpcszDll) + 1;
cdwSize *= sizeof(TCHAR);
lpvAllocation = VirtualAllocEx(hProcess, NULL, cdwSize, MEM_COMMIT, PAGE_EXECUTE_READWRITE);
if (lpvAllocation != NULL)
{
if (WriteProcessMemory(hProcess, lpvAllocation, lpcszDll, cdwSize, NULL))
{
hThread = CreateRemoteThread(hProcess, NULL, 0, (LPTHREAD_START_ROUTINE)LoadLibrary, lpvAllocation, 0, NULL);
if (hThread != NULL)
{
GetExitCodeThread(hThread, (LPDWORD)&hRet);
CloseHandle(hThread);
}
}
VirtualFreeEx(hProcess, lpvAllocation, cdwSize, MEM_DECOMMIT);
}
return hRet;
}
// hook future process creation - install this hook on top of CreateProcessW
// I'd suggest using Microsoft Detours [http://research.microsoft.com/en-us/projects/detours/]
BOOL WINAPI CreateProcessWHook(__in_opt LPCWSTR lpApplicationName, __inout_opt LPWSTR lpCommandLine, __in_opt LPSECURITY_ATTRIBUTES lpProcessAttributes, __in_opt LPSECURITY_ATTRIBUTES lpThreadAttributes, __in BOOL bInheritHandles, __in DWORD dwCreationFlags, __in_opt LPVOID lpEnvironment, __in_opt LPCWSTR lpCurrentDirectory, __in LPSTARTUPINFO lpStartupInfo, __out LPPROCESS_INFORMATION lpProcessInformation)
{
// create the process suspended
if (dwCreationFlags & CREATE_SUSPENDED != CREATE_SUSPENDED)
dwCreationFlags |= CREATE_SUSPENDED;
// call original CreateProcessW
BOOL bRet = _CreateProcessW(lpApplicationName, lpCommandLine, lpProcessAttributes, lpThreadAttributes, bInheritHandles, dwCreationFlags, lpEnvironment, lpCurrentDirectory, lpStartupInfo, lpProcessInformation);
if (bRet)
{
// inject DLL
LoadModuleEx(lpProcessInformation->hProcess, lpszDllName);
// resume thread
ResumeThread(lpProcessInformation->hThread);
}
return bRet;
}
