Problem writing Browser Helper Object
-
I am trying to write a Browser Helper Object, but I am having a problem making it recognisable as a BHO. Following the instructions in Dino Esposito's MSDN article, using VC++6 I generate a standard ATL Com AppWizard project, selecting .DLL as the server type. I then insert an ATL Object, selecting an Internet Explorer Object, leaving all the defaults (appartment threading, dual interface, aggregation, no errorInfo, Connection Points or Free Threaded Marshaller). I then simply add the extra registration into the .RGS file to put the CLSID into HKLM|software|microsoft|windows|Current Version|explorer|Browser Helper Objects. I do not add any extra code, but just build the project. It registers OK, and the CLSID appears in the registry as expected. However, when I run BHODemon (www.definitivesolutions.com), it does not see the new helper, nor, as far as I can tell, does Internet Explorer. I have compared my software with working BHOs such as IEhelper and Dino Esposito's HTMLEdit, but can find nothing to explain my difficulty. Can anyone help? Dave

Did you implement
IObjectWithSite, and put that interface in your COM_MAP so the object responds to QI calls forIObjectWithSite? --Mike-- Personal stuff:: Ericahist | Homepage Shareware stuff:: 1ClickPicGrabber | RightClick-Encrypt CP stuff:: CP SearchBar v2.0.2 | C++ Forum FAQ "Linux is good.

You know that in the RGS file there are 2 CLSID's right? Did you select the correct one?
Well spotted. An excellent bit of remote diagnosis. That's exactly what I didn't do. I selected the wrong one. Thanks. Dave
