I am trying to open powerpoint slide through webbrowser using vb6
when i use ppt2003 this piece of code works :
WebBrowser1.Navigate2 "D:\Documents and Settings\testers\Desktop\ComparePPT\newgrp.ppt"
WebBrowser1.AddressBar = True
this opens the ppt file in the web browser.
But if i try the same code in powerpoint 2007
WebBrowser1.Navigate2 "D:\Documents and Settings\testers\Desktop\ComparePPT\newgrp.ppt"
WebBrowser1.AddressBar = True
then it opens ppt file instread of opening the ppt file in the web browser.
what i did was tried saving the ppt file as .mhtm and opening the newgrp.mhtm but the problem is if we have internet security medium to high then the mhtm file doesnot open and we cant assume that client will have client security as low every time.
