设置壁纸方法

经由过程IActiveDesktop接口来实现

比如设置壁纸,就可以这样

IActiveDesktop *a;

CoInitialize(NULL);

if(SUCCEEDED(CoCreateInstance(Shlobj::CLSID_ActiveDesktop,NULL,CLSCTX_INPROC_SERVER,IID_IActiveDesktop,(void **)&a)))

{

WideString c = "C:\\My Documents\\yw2.jpg";

OleCheck(a->SetWallpaper(c.c_bstr(),0));

OleCheck(a->ApplyChanges(AD_APPLY_ALL));

a->Release();

}

CoUninitialize();

留意在cpp的第一行加入#define NO_WIN32_LEAN_AND_MEAN

并要#include
