How to take a quartz log?

Many a times I do get this questions from my varied customers and colleagues and I cannot answer them instantly or even after looking here and there for a day. So I just wanted to blog it.

Please see the MSDN link http://msdn.microsoft.com/en-us/library/dd388394(v=VS.85).aspx for the steps in getting the logs.

Here are some steps to remember:

DebugRoot = SOFTWARE\Microsoft\DirectShow\Debug (Windows Vista or later)

Registry Location = HKEY_LOCAL_MACHINE\<DebugRoot>\<ModuleName>\<MessageType>

ModuleName = Quartz.dll

MessageType = TRACE

I would recommend making two tests by setting TRACE to:

1. 0x00000003 and

2. 0xFFFFFFFF

So you get two quartz logs.
