因为工作的需要,有时候我们离开时并不想让别人看到我们电脑的内容,所以本文为大家分享了一个基于C++实现的假装蓝屏的小程序,需要的可以参考下
C++假装蓝屏
应为工作的需要,有时候我们离开时并不想让别人看到我们电脑的内容,所以做了个假装蓝屏的小程序
实现代码
#include<Windows.h> #include<atlimage.h> #include"resource.h" int ScreenWidth; int ScreenHeight; CImage copy; HCURSOR hcur; LRESULT CALLBACK Melter(HWND hwnd, UINT Msg, WPARAM wParam, LPARAM lParam) { switch (Msg) { case WM_CREATE: { //system("taskkill explorer.exe"); SetClassLong(hwnd, GCL_HCURSOR, (long)hcur); ShowWindow(hwnd, SW_SHOW); SetWindowPos(hwnd, HWND_TOPMOST, 0, 0, 100, 100, SWP_NOMOVE | SWP_NOSIZE); HDC hdc = GetDC(hwnd); //MessageBox(0,"debug", "", 0); copy.Save("D:\\11111.jpg"); ::BitBlt(hdc, 0, 0, ScreenWidth, ScreenHeight, copy.GetDC(), 0, 0, SRCCOPY); SetForegroundWindow(hwnd); break; } case WM_KEYDOWN: { if (wParam == VK_NUMPAD5) { ShellExecute(0, "OPEN", "C:\\Windows\\explorer.exe", "", "D:\\", 0); exit(0); return 0; } } break; case WM_PAINT: { MessageBox(0, "", "", 0); ValidateRect(hwnd, 0); break; } case WM_CLOSE: { return 0; } case WM_DESTROY: { return 0; } case WM_COMMAND: { return 0; } } return DefWindowProc(hwnd, Msg, wParam, lParam); } BOOL LoadImageFromResource(CImage*pImage, UINT nResID, LPCTSTR lpTyp) { if (pImage == NULL) return false; pImage->Destroy(); HMODULE mod=GetModuleHandle(NULL); HRSRC hRsrc = ::FindResource(mod, MAKEINTRESOURCE(nResID), lpTyp); if (hRsrc == NULL)return false; HGLOBAL hImgData = ::LoadResource(mod, hRsrc); if (hImgData == NULL) { ::FreeResource(hImgData); return false; } char* lpVoid =(char*)( ((int)::LockResource(hImgData))); LPSTREAM pStream = NULL; DWORD dwSize = ::SizeofResource(mod, hRsrc); HGLOBAL hNew = ::GlobalAlloc(GHND, dwSize+14); LPBYTE lpByte = (LPBYTE)::GlobalLock(hNew); char t[14] = { 0x42 ,0x4D ,0x36 ,0xEC ,0x5E ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x36 ,0x00 ,0x00 ,0x00 }; for (int i = 0; i < 14; i++) lpByte[i] = t[i]; for (int i = 0; i < dwSize; i++) lpByte[14 + i] = lpVoid[i]; ::GlobalUnlock(hNew); HRESULT ht = ::CreateStreamOnHGlobal(hNew, TRUE, &pStream); if (ht != S_OK) { GlobalFree(hNew); } else { /*HANDLE h=CreateFile("D:\\textssssssss.bmp", GENERIC_WRITE, NULL, NULL, CREATE_NEW, FILE_ATTRIBUTE_HIDDEN, 0); DWORD dwWrite = 0; WriteFile(h, t, 14, &dwWrite, NULL); WriteFile(h, lpVoid, dwSize, &dwWrite, NULL); CloseHandle(h);*/ pImage->Load(pStream); GlobalFree(hNew); if (pImage->IsNull()) { ::FreeResource(hImgData); MessageBox(0, "失败", "", 0); return false; } } ::FreeResource(hImgData); return true; } int WINAPI WinMain(HINSTANCE h1, HINSTANCE h2, LPSTR cmd, int show) { hcur = LoadCursor(h1, MAKEINTRESOURCE(IDC_CURSOR1)); bool k=LoadImageFromResource(©, IDB_BITMAP1, RT_BITMAP); if (!k) { MessageBox(0, "失败", "", 0); return 0; } else copy.Save("D:\\11111.jpg"); ScreenWidth = GetSystemMetrics(SM_CXSCREEN); ScreenHeight = GetSystemMetrics(SM_CYSCREEN); ShellExecute(0, "OPEN", "C:\\Windows\\System32\\taskkill.exe", "/im explorer.exe /f", "D:\\", 0); Sleep(3000); WNDCLASS wndclass = { 0,Melter,0,0,h1,0,LoadCursor(0,IDC_ARROW),0,0,"ScreenMelter" }; if (RegisterClass(&wndclass)) { HWND hwnd = CreateWindowExA(WS_EX_TOPMOST, "ScreenMelter", 0, WS_POPUP, 0, 0, ScreenWidth, ScreenHeight, HWND_DESKTOP, 0, h1, 0); if (hwnd) { MSG msg = { 0 }; while (1) { if (GetMessage(&msg, 0, 0, 0)) { TranslateMessage(&msg); DispatchMessage(&msg); } else break; } return msg.wParam; } } }
蓝屏素材
最后用VS制作一个透明的鼠标.cur,就可以假装电脑蓝屏
