How to comunicate between zwo ActiveX Controls

For any object that needs to communicate with another, the best way to do that is to register itself with the IROT (IRunningObjectTable). Then other objects can detect if you're there or not by calling IRunningObjectTable::GetObjet().

One you have the interface, you can query it for any other interfaces you have defined for that communication.

But how can I get the pointer to the moniker on the Object (Parameter i need for calling GetObject)

But how can I get the pointer to the moniker on the Object (Parameter i need for calling GetObject)

Message to thui: Sorry, I'm a new user of this tool. Your anser was not bad but I need an example, how to implement. Maybe it was wrong to open the question for other users...

How do I access IE's object model from a contained control?

IE supports an Automation interface called IWebBrowserApp. It also supports an object model for scripting through a hierarchy of interfaces, the root of which is IHTMLDocument. The IHTMLDocument interface has one property, Script, which returns the dispinterface for the IOmWindow interface. This corresponds to the window object described in the ActiveX SDK documentation. From a contained control or doc object, you can get the dispinterface for IWebBrowserApp with the following code:


IOleClientSite* pClientSite; // already points to the control's client site
IServiceProvider* pISP;
IDispatch* pIEIDisp;


pClientSite->QueryInterface(IID_IServiceProvider, (void **)&pISP);
pISP->QueryService(IID_IWebBrowserApp, IID_IDispatch, (void **)&pIEIDisp);


To get the dispinterface for IHTMLDocument, given that you already have the ISP pointer as above, you can use this code:


IDispatch* pScriptIEDisp;
pISP->QueryService(SID_SContainerDispatch, IID_IDispatch, (void**)&pScriptIEDisp);

I think, the anser of thui was better, but I don't know how to implement.

Question specification: I need informations about using the IRunningObjectTable (Register, GetObject and how to get the pointer to the Moniker)

Thanks
