    <p>Probably a rookie error, but i'm getting something strange. i'm trying to weave a .NET performance counter into an application. </p> <p>When i call the <code>incrementBy(value)</code> method on my avg performance counter it is changing the RawValue of my base counter by value as well. i checked the variable names and think everything is correct.</p> <p>Then when i call <code>increment()</code> on my base counter it adds 1 to the rawvalue of the avgcounter as well as incrementing the base counter... adding insult to injury!</p> <p>Has anyone else seen this kind of behavior? Any suggestions for what's going on and how to fix it?</p> <p>In code i'm using two different counters to measure the time a merge sort i wrote takes. i have a instantaneous counter for the elapsed time of the sort and an average counter.</p> <pre><code>Dim timePiece As New Stopwatch() timePiece.Start() MergeSort() timePiece.Stop() ElapsedCounter.RawValue = timePiece.ElapsedMilliseconds AvgCounter.IncrementBy(timePiece.ElapsedMilliseconds) AvgCounterBase.Increment() </code></pre> <p>What i'm seeing occur is:</p> <pre><code>'Elapsed counter works as expected 'AvgCounter RawValue is 7, AvgCounterBase RawValue is also 7 before incrementing </code></pre> <pre> AvgCounter.IncrementBy(value) 'AvgCounter.RV is 7+value, AvgCounterBase is 7+value AvgCounterBase.Increment() 'AvgCounter.RV is 7+value+1, AvgCounterBase is 7+value+1 </pre> <p>i think i may be using the counters wrong, but why does changing the rawvalue of the average seem to also change the rawvalue of the base? i dont think that's supposed to happen.</p>

    1. COI don't understand what you are expecting to happen. Could you clarify your example with concrete values, and what you expect rawValue to be after each statement?

    2. COalright i edited the question. hopefully it's more clear now. Thanks for the input.

    3. COhmm... i never did catch this one. But i refactored my code completely and that seemed to help. i'll just chalk this one up to poor design i guess.

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.
