关于弹出消息窗口的自动关闭

转自：https://blog.youkuaiyun.com/saiolive/article/details/51907954

 

1.方法1

1.1. 直接在代码中添加

 

1. // 弹出消息窗口自动关闭，需要指出的是，Windows 2000的user32.dll没有导出这个函数。

2. extern "C"

3. {

4. int WINAPI MessageBoxTimeoutA(IN HWND hWnd, IN LPCSTR lpText, IN LPCSTR lpCaption, IN UINT uType, IN WORD wLanguageId, IN DWORD dwMilliseconds);

5. int WINAPI MessageBoxTimeoutW(IN HWND hWnd, IN LPCWSTR lpText, IN LPCWSTR lpCaption, IN UINT uType, IN WORD wLanguageId, IN DWORD dwMilliseconds);

6. };

7. #ifdef UNICODE

8. #define MessageBoxTimeout MessageBoxTimeoutW

9. #else

10. #define MessageBoxTimeout MessageBoxTimeoutA

11. #endif

 

 

1.2. 调用

 

1. MessageBoxTimeout(this->GetSafeHwnd(), _T("弹出5秒后会自动关闭！这是一个模态对话框。"), _T("会自动关闭的MessageBox"), MB_ICONINFORMATION, GetSystemDefaultLangID(), 5000);

2. //参数说明：父窗口的句柄为NULL的情况下，将弹出非模态对话框；延时关闭的时间为0的情况下，弹出的MessageBox需要手动关闭

3. MessageBoxTimeout(NULL, _T("弹出5秒后会自动关闭！这是一个非模态对话框。"), _T("会自动关闭的MessageBox"), MB_ICONINFORMATION, GetSystemDefaultLangID(), 5000);

win7 x86，vs2013，测试通过

 

2.方法2

 

2.1.此api是微软的一个未公开api，在user32.dll中，功能就是弹出一个对话框MessageBox，并定时自动退出。 
下面为头文件，随便取个名字，我取的是MsgBoxTimeout.h 。

 

1. #include <windows.h>

2. #include <tchar.h>

3.  

4. //Functions & other definitions required-->

5. typedef int (__stdcall *MSGBOXAAPI)(IN HWND hWnd,

6. IN LPCSTR lpText, IN LPCSTR lpCaption,

7. IN UINT uType, IN WORD wLanguageId, IN DWORD dwMilliseconds);

8. typedef int (__stdcall *MSGBOXWAPI)(IN HWND hWnd,

9. IN LPCWSTR lpText, IN LPCWSTR lpCaption,

10. IN UINT uType, IN WORD wLanguageId, IN DWORD dwMilliseconds);

11.  

12. int MessageBoxTimeoutA(IN HWND hWnd, IN LPCSTR lpText,

13. IN LPCSTR lpCaption, IN UINT uType,

14. IN WORD wLanguageId, IN DWORD dwMilliseconds);

15. int MessageBoxTimeoutW(IN HWND hWnd, IN LPCWSTR lpText,

16. IN LPCWSTR lpCaption, IN UINT uType,

17. IN WORD wLanguageId, IN DWORD dwMilliseconds);

18.  

19. #ifdef UNICODE

20. #define MessageBoxTimeout MessageBoxTimeoutW

21. #else

22. #define MessageBoxTimeout MessageBoxTimeoutA

23. #endif

24.  

25. #define MB_TIMEDOUT 32000

26.  

27. int MessageBoxTimeoutA(HWND hWnd, LPCSTR lpText,

28. LPCSTR lpCaption, UINT uType, WORD wLanguageId,

29. DWORD dwMilliseconds)

30. {

31. static MSGBOXAAPI MsgBoxTOA = NULL;

32.  

33. if (!MsgBoxTOA)

34. {

35. HMODULE hUser32 = GetModuleHandle(_T("user32.dll"));

36. if (hUser32)

37. {

38. MsgBoxTOA = (MSGBOXAAPI)GetProcAddress(hUser32,

39. "MessageBoxTimeoutA");

40. //fall through to 'if (MsgBoxTOA)...'

41. }

42. else

43. {

44. //stuff happened, add code to handle it here

45. //(possibly just call MessageBox())

46. return 0;

47. }

48. }

49.  

50. if (MsgBoxTOA)

51. {

52. return MsgBoxTOA(hWnd, lpText, lpCaption,

53. uType, wLanguageId, dwMilliseconds);

54. }

55.  

56. return 0;

57. }

58.  

59. int MessageBoxTimeoutW(HWND hWnd, LPCWSTR lpText,

60. LPCWSTR lpCaption, UINT uType, WORD wLanguageId, DWORD dwMilliseconds)

61. {

62. static MSGBOXWAPI MsgBoxTOW = NULL;

63.  

64. if (!MsgBoxTOW)

65. {

66. HMODULE hUser32 = GetModuleHandle(_T("user32.dll"));

67. if (hUser32)

68. {

69. MsgBoxTOW = (MSGBOXWAPI)GetProcAddress(hUser32,

70. "MessageBoxTimeoutW");

71. //fall through to 'if (MsgBoxTOW)...'

72. }

73. else

74. {

75. //stuff happened, add code to handle it here

76. //(possibly just call MessageBox())

77. return 0;

78. }

79. }

80.  

81. if (MsgBoxTOW)

82. {

83. return MsgBoxTOW(hWnd, lpText, lpCaption,

84. uType, wLanguageId, dwMilliseconds);

85. }

86.  

87. return 0;

88. }

89. //End required definitions <--

2.2. 调用方式

 

 

1. #include "MsgBoxTimeout.h"

2. void CTestDlg::OnBnClickedButton2()

3. {

4. //you must load user32.dll before calling the function

5. HMODULE hUser32 = LoadLibrary(_T("user32.dll"));

6.  

7. if (hUser32)

8. {

9. int iRet = 0;

10. UINT uiFlags = MB_OK | MB_SETFOREGROUND | MB_SYSTEMMODAL | MB_ICONINFORMATION;

11.  

12. iRet = MessageBoxTimeout(NULL, _T("Test a timeout of 2 seconds."),

13. _T("MessageBoxTimeout Test"), uiFlags, 0, 2000);

14. //iRet will = 1

15.  

16. uiFlags = MB_YESNO | MB_SETFOREGROUND | MB_SYSTEMMODAL | MB_ICONINFORMATION;

17.  

18. iRet = MessageBoxTimeout(NULL, _T("Test a timeout of 5 seconds."),

19. _T("MessageBoxTimeout Test"), uiFlags, 0, 5000);

20. //iRet will = MB_TIMEDOUT if no buttons pressed, button values otherwise

21.  

22. //only unload user32.dll when you have no further need

23. //for the MessageBoxTimeout function

24. FreeLibrary(hUser32);

25. }

26. }
