If you have a C++ class class Z : public X, public Y { }; then you may be surprised to find that this is not a pointer to Y. Basic C++. But static_cast(this) is. You need a separate if(riid == IID_...){...} for each IID

What does the documentation say about the format of this value? Your original sample code stated that it is an INT8, but you are displaying it as (a very small) floating point number. Use the best guess

Straight from the TinyXML website: Quote: To Use in an Application: Add tinyxml.cpp, tinyxml.h, tinyxmlerror.cpp, tinyxmlparser.cpp, tinystr.cpp, and tinystr.h to your project or make file.

I'm not sure if this is relevant to you, but you can call bind[^] on the ip address and port, check if it fails and see if the error is WSAEADDRINUSE. «_Superman_»  _I love work.

Try the IDocHostUIHandler::ShowContextMenu[^] method. Steve

The third parameter to DialogBox is still NULL - DialogBox((HINSTANCE)g_hinst, MAKEINTRESOURCE(IDD_DIALOG1),**NULL**, InputBox_WndProc); You need to specify the handle to the parent window here. «_Superman_»  _I love work.
