Internet Explorer Toolbar button.

Internet Explorer Extension Development

hypodyne

I am trying to add a button to the internet explorer toolbar. It shows up on the toolbar but nothing happens when I click the button. The button is pressed.

I ve been trying to get this working for weeks.  

I have added all the values to the registry ButtonText, CLSID, ClsidExtension, Default Visible, HotIcon, Icon, MenuText which shows up in regedit.

I have registered the com object and it shows up in regedit.

Here is the setup project (inno setup program)

Hi,

Try using a different GUID value for the Extenstion key from the CLSIDExtension value.

What is the entry point to your dll - it should be the default - main()

QueryStatus is generally used to determine the button state (hot or cold) in order to toggel its view state.

I just had a look at the Add-to Zone sample from IE downloads.... (webzone.dll)... only difference is the ThreadingModel = Apartment

Regards.

The button works as in it changes when you mouse over it. Although if I put a messageBox in the function definition then it does not pop up.

I am not sure what you mean by entry point of the dll means.. As far as I know the Exec function is called when you press the button. Although it does not work. Executables have a main function and are easy to get working using IE toolbuttons. But as I will in future want to access the webpage so I can take a screen shot of the client area I need to use a DLL. As far as i know anyway.

Can you please give me the full link to the example you mentioned because the only webzone example i could find had nothing to do with IE or implement IUnknown.
