    <p>I have a method which tests for the existence of a file prior to carrying out some manipulation of file content as follows:</p> <pre><code>Private Sub AddHeaderToLogFile() ''#Only if file does not exist If Not File.Exists(_logPath) Then Dim headerLogger As Logger headerLogger = LogManager.GetLogger("HeaderLogger") ''#Use GlobalDiagnosticContext in 2.0, GDC in pre-2.0 NLog.GlobalDiagnosticsContext.Set("appName", _appName) NLog.GlobalDiagnosticsContext.Set("fileVersion", _fileVersion) NLog.GlobalDiagnosticsContext.Set("logId", 0) headerLogger.Info("") End If End Sub </code></pre> <p>The idea is that if the file does not exist, then the file is generated by calls to the NLog logger instance, at which point the file is created and the specified header info is inserted. The method works fine from the application itself, however I have a simple NUnit test which implements a test method to verify that the file is created and populated as expected. When I step through with the debugger, I find that '_logPath' is set to:</p> <p>D:\Documents and Settings\TE602510\Local Settings\Temp\nunit20\ShadowCopyCache\4288_634286300896838506\Tests_-1937845265\assembly\dl3\7cdfe61a\aa18c98d_f0a1cb01\logs\2010-12-22.log</p> <p>Unfortunately, despite the fact that the file DOES exist, the call to File.Exists returns false. From earlier viewing of the config path the above path would appear to be correct for these NUnit tests. Does anybody have a clue what is happening here and what I need to do to get the desired result? The pathname to the log file as per the XP file system is:</p> <p>D:\Documents and Settings\TE602510\My Documents_VSSWorkArea\PsalertsIp\Tests\bin\Debug\logs</p> <p>Kind Regards</p> <p>Paul J.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
