环境：Windows NT/2000

实现方法：采用将动态连接库注入到其他进程中的方法来实现。

为了便于选择窗口，我借用了另一个程序"2000下显示带*号"来选择窗口。
如果要在98下实现你可用钩子同样实现。
程序运行界面如图一：

将动态连接库注入其他进程的代码如下：

BOOL WINAPI RT_CTRL_BTN(LPCSTR lpszLibFile, HWND hWnd, DWORD dwID, LPRECT pRtBtn, LPCTSTR szCaptionBtn){try {DWORD dwProcessID;GetWindowThreadProcessId(hWnd, &dwProcessID);HANDLE hProcess = OpenProcess( PROCESS_CREATE_THREAD | PROCESS_VM_OPERATION |PROCESS_VM_WRITE | PROCESS_VM_READ, FALSE, dwProcessID );if (!hProcess){return FALSE;}INJECT_DLL InjectInfo;InjectDLL_Info(&InjectInfo, lpszLibFile, hWnd, dwID, pRtBtn, szCaptionBtn);LPBYTE lpThreadAddr=(LPBYTE)::VirtualAllocEx(hProcess, NULL, MAXINJECTSIZE, MEM_COMMIT, PAGE_EXECUTE_READWRITE);LPINJECT_DLL param = (LPINJECT_DLL) VirtualAllocEx( hProcess, 0, sizeof(INJECT_DLL), MEM_COMMIT, PAGE_READWRITE );WriteProcessMemory(hProcess, lpThreadAddr,&RemoteControlThread,MAXINJECTSIZE, 0);WriteProcessMemory( hProcess, param, &InjectInfo, sizeof(InjectInfo), 0 );DWORD dwThreadId;HANDLE hThread = ::CreateRemoteThread(hProcess,NULL,0,(unsigned long (__stdcall *)(void *))lpThreadAddr,param, 0, &dwThreadId);if (!hThread){CloseHandle(hProcess);VirtualFreeEx( hProcess, lpThreadAddr, 0, MEM_RELEASE );VirtualFreeEx( hProcess, param, 0, MEM_RELEASE );return FALSE;}else {CloseHandle(hThread);CloseHandle(hProcess);VirtualFreeEx( hProcess, lpThreadAddr, 0, MEM_RELEASE );VirtualFreeEx( hProcess, param, 0, MEM_RELEASE );}}catch (...){return FALSE;}return TRUE;}

环境：win2000 professional + VC6.0+SP5 + PlatformSDK 2001.8
