Use the idochostuihandler interface to shield the webbrowser pop-up menu

To put it simply, the idochostuihandler interface is implemented. The interface attached with the idochostuihandler interface can be implemented using the icustomdoc interface or the ioleobject interface. Here we demonstrate the use of the icustomdoc interface for mounting. To shield the webbroswer pop-up menu, you only need to write an article on the showcontextmenu method of the idochostuihandler. Other methods of the idochostuihandler do not need to be processed, but you must implement them, even if you only write some comments, let's look at the code below:
'Button on the form, a tetbox, a checkbox, and a webbrowser
'Here I still reference edanmo's Ole interfaces & functions v1.81 (corresponding file olelib. TLB)
Option explicit
Implements idochostuihandler
Dim mshow as Boolean

Private sub checkduplicate click ()

End sub

Private function idochostuihandler_translateurl (byval dwtranslate as long, byval pchillin as long) as long

Finally, it should be noted that this program may have some problems, so that it cannot work well in the vb ide (to what's the reason, I have no time to study it now. Let's talk about it later, you know, please tell me). However, after compiling it into an EXE file, it can still achieve our goal.
