MFC project with DirecInput

akira32

I create a MFC project in VS2008.
And I want to use DirectInput in this project.
But I met a problem of Unepected error encountered when I SetCooperativeLevel in keyboard and mouse.
Can MFC project use the DirectInput?
I should use which value of SetCooperativeLevel for keyboard and mouse.

1. 
   
2. void DirectInput::DirectInputInit(HINSTANCE AppInstance,HWND hWnd)
   
3. {
   
4.         ZeroMemory(mKeyboardState, sizeof(mKeyboardState));
   
5.         ZeroMemory(&mMouseState, sizeof(mMouseState));
   
6. 
   
7.         HR(DirectInput8Create(AfxGetInstanceHandle(), DIRECTINPUT_VERSION,
   
8.                 IID_IDirectInput8, (void**)&mDInput, 0));
   
9. 
   
10.         HR(mDInput->CreateDevice(GUID_SysKeyboard, &mKeyboard, 0));
    
11.         HR(mKeyboard->SetDataFormat(&c_dfDIKeyboard));
    
12.         HR(mKeyboard->SetCooperativeLevel(m_hWnd, DISCL_NONEXCLUSIVE|DISCL_FOREGROUND));
    
13.         HR(mKeyboard->Acquire());
    
14. 
    
15.         HR(mDInput->CreateDevice(GUID_SysMouse, &mMouse, 0));
    
16.         HR(mMouse->SetDataFormat(&c_dfDIMouse2));
    
17.         HR(mMouse->SetCooperativeLevel(m_hWnd, DISCL_NONEXCLUSIVE|DISCL_FOREGROUND));
    
18.         HR(mMouse->Acquire());
    
19. }

MFC程序肯定能使用DirextInput的，虽然我是用得VS2003
不过我的印象中创建input对象时使用的句柄应该和创建Device是一样的句柄，MFC如果是文档视结构的应该使用MainFrm的句柄创建
DirectInput8Create的第一个参数和你后来SetCooperativeLevel的第一个参数是同一个句柄吗？从你贴出的代码没法看出m_hWnd的值到底是什么

DirectInput di;

di.DirectInputInit(AfxGetInstanceHandle(), m_pMainFrame->m_hWnd,DISCL_NONEXCLUSIVE|DISCL_FOREGROUND , DISCL_NONEXCLUSIVE|DISCL_FOREGROUND );
gDInput = &di;

void DirectInput:irectInputInit(HINSTANCE AppInstance,HWND hWnd,DWORD keyboardCoopFlags, DWORD mouseCoopFlags)
{
        ZeroMemory(mKeyboardState, sizeof(mKeyboardState));
        ZeroMemory(&mMouseState, sizeof(mMouseState));

        HR(DirectInput8Create(AppInstance, DIRECTINPUT_VERSION,
                IID_IDirectInput8, (void**)&mDInput, 0));

        HR(mDInput->CreateDevice(GUID_SysKeyboard, &mKeyboard, 0));
        HR(mKeyboard->SetDataFormat(&c_dfDIKeyboard));
        HR(mKeyboard->SetCooperativeLevel(hWnd, keyboardCoopFlags));
        HR(mKeyboard->Acquire());

        HR(mDInput->CreateDevice(GUID_SysMouse, &mMouse, 0));
        HR(mMouse->SetDataFormat(&c_dfDIMouse2));
        HR(mMouse->SetCooperativeLevel(hWnd, mouseCoopFlags));
        HR(mMouse->Acquire());
}
