MFC编写的DLL 键盘钩子注入问题。

奋斗2013

环境：VS2008 WINXP
编写的一个MFC的DLL
经测试代码应该错在呼出窗体和隐藏窗体
DLL代码如下：

1. GameInfo *Gamedlg;
   
2. HHOOK g_hHook;
   
3. LRESULT CALLBACK GameProc(int nCode, WPARAM wParam, LPARAM lParam); //键盘钩子
   
4. //////////////////////////////////////////////////////////////////////////
   
5. LRESULT CALLBACK GameProc(int nCode, WPARAM wParam, LPARAM lParam)
   
6. {
   
7. AFX_MANAGE_STATE(AfxGetStaticModuleState()); //宏
   
8. //BOOL bKeyUp = lParam & (1<<31);
   
9. //if (bKeyUp && wParam == VK_HOME && nCode == HC_ACTION) //HOME为热键
   
10. if ((wParam==VK_HOME) && (lParam&(1<<31))==0)
    
11. {
    
12. if (Gamedlg==NULL) //如果GameDlg是空的 说明没有窗体
    
13. {
    
14. //AFX_MANAGE_STATE(AfxGetStaticModuleState());//宏
    
15. CWnd *pCWnd = CWnd::GetForegroundWindow();
    
16. Gamedlg=new GameInfo;
    
17. Gamedlg->Create(IDD_GameMain,pCWnd);
    
18. //Gamedlg->Create(IDD_GameMain);
    
19. Gamedlg->ShowWindow(SW_SHOW);
    
20. }
    
21. else
    
22. {
    
23. Gamedlg->ShowWindow(Gamedlg->IsWindowVisible() ? SW_HIDE : SW_SHOW);
    
24. //Gamedlg->ShowWindow(Gamedlg->IsWindowVisible() ? SW_SHOW:SW_HIDE);
    
25. //Gamedlg->ShowWindow(SW_HIDE);
    
26. //Gamedlg=NULL;
    
27. }
    
28. }
    
29. return ::CallNextHookEx(g_hHook, nCode, wParam, lParam);
    
30. }
    
31. void SetHook()
    
32. {
    
33. AFX_MANAGE_STATE(AfxGetStaticModuleState());
    
34. //HWND GameH=::FindWindow(L"SciCalc",L"计算器"); //音乐播放器 By:年少 QQ:348619517
    
35. //HWND GameH=::FindWindow(NULL,L"无标题 - 记事本");
    
36. //HWND GameH=::FindWindow(NULL,L"音乐播放器 By:年少 QQ:348619517");
    
37. HWND GameH=::FindWindow(L"TFrmMain",L"legend of mir2");
    
38. if (GameH==0)
    
39. {
    
40. AfxMessageBox(L"未找到游戏进程！",MB_OK);
    
41. return ;
    
42. }
    
43. DWORD ProcID=::GetWindowThreadProcessId(GameH,NULL);
    
44. g_hHook=::SetWindowsHookEx(WH_KEYBOARD,&GameProc,GetModuleHandle(L"SoftDll.dll"),ProcID);
    
45. if (g_hHook!=NULL)
    
46. {
    
47. AfxMessageBox(L"DLL注入成功！",MB_OK);
    
48. return;
    
49. }
    
50. }
    
51. BOOL CSoftDllApp::InitInstance()
    
52. {
    
53. CWinApp::InitInstance();
    
54. return TRUE;
    
55. }
    
56. BOOL CSoftDllApp::ExitInstance()
    
57. {
    
58. delete Gamedlg;
    
59. Gamedlg = NULL;
    
60. return CWinApp::ExitInstance();
    
61. //ShowWindow(Gamedlg->m_hWnd,SW_HIDE); //这样做 退出时会报内存错
    
62. return TRUE;
    
63. }

注入计算器 记事本都可以 按Home键呼出 按Home键隐藏 很好用。  (游戏没有保护)
