DuiLib编译时提示“ 无法打开文件“Riched20.lib””

1.首先移除项目中包含的Riched20.lib静态库，在linker中。

2.找到RichEditUI.cpp中的如下代码：

// Create Text Services component
if(FAILED(CreateTextServices(NULL, this, &pUnk)))
    goto err;
3.用下面的代码替换上面的两行代码：
typedef HRESULT(_stdcall *CTSFunc)(IUnknown *punkOuter, ITextHost *pITextHost, IUnknown **ppUnk);
CTSFunc ctsFunc = NULL;
m_hRiched20 = LoadLibrary(_T("Riched20.dll"));

if (NULL == m_hRiched20)
    goto err;
else
{
    ctsFunc = (CTSFunc)GetProcAddress(m_hRiched20, "CreateTextServices");

    if (NULL == ctsFunc)
        goto err;
}

if (FAILED(ctsFunc(NULL, this, &pUnk)))
    goto err;
4.在这个类中的析构函数中释放掉Riched20.dll动态库
FreeLibrary(m_hRiched20);
