Win32 SDK 中的RichEdit如何让它插入图片？

Question

Win32 SDK 中的RichEdit如何让它插入图片？ 我建立了一个，插入不了图片。

Answer 1

wiin32SDK中的RichEdit插入图片需要手动实现一些接口，代码如下：   ////接口声明///////////////////////////////////////////////////////
   interface IExRichEditOleCallback : public IRichEditOleCallback
   {
   public :   IExRichEditOleCallback();

m_pIRichEditOleCallback = new IExRichEditOleCallback;
SendMessage(hwndRichEdit,EM_SETOLECALLBACK, 0,(LPARAM)m_pIRichEditOleCallback);
这样就可以粘贴进图片了
保险起见：程序加载时：LoadLibrary(TEXT("Riched20.dll"));//如不需要以后可去掉如有疏漏可查看网上相关资料

注：程序里的MB是我当初测试时加的宏，其实就是MessageBox,楼主注释掉即可
