关于actxcontrol
 

最近在尝试用MATLAB实现treeview控件，使用h_tv=actxcontrol('mscomctllib.treeCtrl.2',[10 50 300 400],f);时，系统出错，错误信息为：
??? Error using ==> actxcontrol at 216
Control creation failed. Invalid ProgID 'mscomctllib.treeCtrl.2'

Error in ==> xiugai at 2
h_tv=actxcontrol('mscomctllib.treeCtrl.2',[10 50 300 400],f);
请诸位高手不吝赐教！
