Code：

this.axFraCtrlShowPPT.Open("e:\\1.ppt",true,"PowerPoint.Show",null,null);//open file
this.axFraCtrlShowPPT.PPTPlay();//Try to read or write protected memory this usually indicating other memory has been damaged

I want to open a ppt in the axFrameControl,and play the ppt after opening it,but it encoutered an error when it was playing ppt. Can you give me the correct answer?
