How do I write to the VB6 immediate window from C++ based COM object?

I have developed a C++ based COM object to use it in a VB6 application. Now I need to add some logging to catch some of the bugs. I discovered from the answer to 'How to debug COM object in Visual Studio 6.0' 开发者_开发问答question that I can use the OutputDebugString function. But is it possible to write to the VB6 immediate window somehow?

Rather than attempting to write to the immediate window, it would be generally more useful to use DebugView from Sysinternals (now part of Microsoft technet):

DebugView is an application that lets you monitor debug output on your local system, or any computer on the network that you can reach via TCP/IP. It is capable of displaying both kernel-mode and Win32 debug output, so you don't need a debugger to catch the debug output your applications or device drivers generate, nor do you need to modify your applications or drivers to use non-standard debug output APIs.

You can use this during development and also in production.

Under Windows 2000, XP, Server 2003 and Vista DebugView will capture:

• Win32 OutputDebugString
• Kernel-mode DbgPrint
• All kernel-mode variants of DbgPrint implemented in Windows XP and Server 2003

I don't think you can write direct to it but you can use a COM event that just contains a debug.print call.
