Hi Andrey,
The add_common_attributes function works for narrow-character logging. Wide-character counterpart is wadd_common_attributes. This may be the culprit, since the standard attributes are not found by the formatter and thus no log record passes to the sink. You should be able to see that by exceptions that are thrown by the formatter, unless you suppress them.
Thanks for your prompt reply. I changed the code to wadd_common_attributes() but the log still did not get created. Am I right in mentioning the strings like TimeStamp with L"TimeStamp" and ketwords::file_name = L"C:\\test\\test.log" during initialization. One warning that I get during compilation is the following. Does the following relevant to my problem? I noticed I got the same warning when compiling for normal character as well. c:\documents and settings\administrator\my
