20160531 VS2013編譯duilibv1.1，“找不到Riched20.lib”的問題

1、打開DuiLib工程的屬性頁，進入“鏈接器” - “輸入”選項界面。

2、刪除Debug/Release/UnicodeDebug/UnicodeRelease幾個配置中，“附加依賴項”中的“Riched20.lib”（如圖1）。

3、打開UIRichEdit.cpp定位到如下源代碼：

// Create Text Services component
if(FAILED(CreateTextServices(NULL, this, &pUnk)))
goto err;

4、將該段代碼修改爲如下內容：

HINSTANCE richHandle = NULL;
typedef HRESULT  (_stdcall *_CTS)(
    IUnknown *punkOuter,
    ITextHost *pITextHost,
    IUnknown **ppUnk) ; 
_CTS CTS = NULL;
richHandle = LoadLibraryW(L"Riched20.dll");
if(richHandle == NULL)
exit(0);
else
{
CTS = (_CTS)GetProcAddress(richHandle, "CreateTextServices");
if(NULL == CTS)
    exit(0);
}
// Create Text Services component
if(FAILED(CTS(NULL, this, &pUnk)))
goto err;
FreeLibrary(richHandle);
