brew wallpaper 的问题

[locaiver]

在创建wallpaper的实例时，返回nErr=3；
代码如下：

nErr=ISHELL_CreateInstance(pMe->piShell,AEECLSID_Wallpaper,(void**)&pMe->piWallpager);
DBGPRINTF("nErr=%d",nErr);

看sdk，有以下一句话：Use ISHELL_CreateInstance(pIShell, AEECLSID_Wallpaper, (void **)&po). Requires AEEPRIVID_WallpaperConfigure group membership to instantiate.
我怀疑是权限的问题，于是我在mif文件里给他加上了AEEPRIVID_WallpaperConfigure 权限，但问题依旧，有哪位高手可以帮我解答一下吗？不胜感激。

你使用的是BMP的那个版本？在MFX文件中的权限你是如何设定的呢？

应该不是版本不兼容的问题，因为之前涉及到的setting和window的地方都可以成功创建，以下是我的mif文件配置，为了防止有遗漏的权限，我把所有可能会涉及到的权限全加进去了，但还是不行。请大侠帮帮我吧，我实在没辙了。

AEECLSID_Wallpaper,这个ID是不是错误的

你的代码没有问题，我新建了一个工程，然后创建nErr=ISHELL_CreateInstance(pMe->piShell,AEECLSID_Wallpaper,(void**)&pMe->piWallpager);
DBGPRINTF("nErr=%d",nErr);
设好权限以后，没有问题，返回0.你重新建一个工程试试。

好像是啊，新建了一个还真就行了。那您做过wallpaper么？我在这方面遇到了好多问题。
