我正在使用直接显示示例ezrgb24并尝试公开其专用接口。
在iez.h文件中具有以下代码

DEFINE_GUID(IID_IIPEffect,
0xfd5010a3, 0x8ebe, 0x11ce, 0x81, 0x83, 0x00, 0xaa, 0x00, 0x57, 0x7d, 0xa1);

DECLARE_INTERFACE_(IIPEffect, IUnknown)
{
    STDMETHOD(get_IPEffect) (THIS_
                int *effectNum,         // The current effect
                REFTIME *StartTime,     // Start time of effect
                REFTIME *Length         // length of effect
             ) PURE;

    STDMETHOD(put_IPEffect) (THIS_
                int effectNum,          // Change to this effect
                REFTIME StartTime,      // Start time of effect
                REFTIME Length          // Length of effect
             ) PURE;
};


建立dll后,我使用cmd窗口注册了它。
我应该如何从我们的项目中公开或使用get_IPEffect()或put_IPEffect()?

我编码如下,但没有奏效

DEFINE_GUID(IID_IIPEffect,
    0xfd5010a3, 0x8ebe, 0x11ce, 0x81, 0x83, 0x00, 0xaa, 0x00, 0x57, 0x7d, 0xa1);
DEFINE_GUID(CLSID_ImageEffect,
    0x8B498501, 0x1218, 0x11CF, 0xAD, 0xC4, 0x00, 0xA0, 0xD1, 0x00, 0x04, 0x1B);

IBaseFilter *pImageEffect = NULL;
chr = CoCreateInstance(CLSID_ImageEffect, NULL, CLSCTX_INPROC_SERVER,
            IID_IBaseFilter, (void**) &pImageEffect);
chr = pGraph->AddFilter(pImageEffect, L"RGB Resizer");


IIPEffect *pEZrgb24 = NULL;
chr = pImageEffect->QueryInterface(IID_IIPEffect, (void **) &pEZrgb24);


在IIPEffect上,我得到一个错误“'IIPEffect':未声明的标识符”
我该怎么宣布呢?

最佳答案

感谢RomarR和Wimmel,我将iez.h包含在我的项目中,并且运行良好
