1. BeforeNavigate2 not fire
\nUsing C# to create BHO is very simple, but while you following the guide on web, you may found your “BeforeNavigate2” event may not fire\/trigger.
\nThat’s because a .NETFramework bug, until 4.5.1 this bug still exist. It has been fix after .NETFramework 4.6<\/p>\n
If you can’t use C#, you can also use VB or VC++, many guides on web are using C++ (ATL).
\nBUT if you can’t use ATL, there also a guide of write BHO in plain C, without ATL and MFC
\nhttp:\/\/www.codeproject.com\/Articles\/37044\/Writing-a-BHO-in-Plain-C
\nNOTE: there is a bug of PostData in the guide code, other reader find and give out solution in comments under that artical.<\/p>\n
2. Modify PostData
\nI just want to modify\/change the postdata user submit using “BeforeNavigate2”, like this man: http:\/\/www.dotnetbbs.com\/76634257\/
\nSimple assige true to “Cancel” will stop the page navigate, but assign anything to “PostData” has no effect.
\nI have tried to call browser.Navigate() inside BeforeNavigate2 handler, it does work, and will cause continuly invoke BeforeNavigate2.<\/p>\n
