as shown above , There is an internal vpn web site , I want to use the _ IECreateEmbedded and GUICtrlCreateObj simulate IE Web browser To operate it.

But a problem that hasn't encountered before is that the Web-Page needs to install several plug-ins (Related to print , database , flash ,and security so on) .

the Real IE browser can be installed and works properly .

However , the _ IECreateEmbedded and GUICtrlCreateObj simulations , always prompt that the plug-in is not installed .

Are there any relevant posts and examples in the forum? I'm not very good at searching, I did n' t find a similar post.
Is there any solution ?

Thanks in advance !
