Hi,

I have a project that is a com dll plugin to a host application.
The maker of the host application lets us get pointers to various data stucts
such as the UIContext structure like this.

C++

ISonarUIContext3*		m_pSonarUIContext3;

From which I can get the current UI Context running in the Host app:

C++

m_pSonarUIContext3->GetUIContextEx( SurfaceIDs[0], &uiContainer );

Cool.

But I need to now check the UI context from a hook proc.

So I tried to use a static instance of my plugin class as I do with variables.

C++

StaticCBCRMaster->m_pSonarUIContext3->GetUIContextEx( SurfaceIDs[0], &uiContainer );

Which compiles, but can't link because the stuct in the host app is protected and not static.

I'm not going to be able to ever call GetUIContextEx() from a hook proc am I.

If the class you want to call has protected members, maybe you could make a subclass of that class which will give you access?

Ya lost me. :-)

I have a method provided in the host binary called GetUIContextEx() that is protected (This is what the linker says when I tried to call it directly).

I don't know the class name and am not privied to it.

it's a COM itf, so can't you just AddRef to the interface from your hook proc, #importing the TLB?

I found a work around:

Instead of doing the work in the hook proc, I just set a flag to do the work so when a 75 ms refresh timer calls my code I check the flag and do the work where I have unfettered access to the function.

It seems to be working - needs lots of testing.

Sorry to be a bother again and thanks to all who replied.
