    <p>I am using the ManagedWindows API in a C# environment: <a href="http://mwinapi.sourceforge.net/" rel="nofollow">http://mwinapi.sourceforge.net/</a></p> <p>In the past I have successfully scraped the contents of listbox-like parts of other running programs using the code below, where I iterate through key/value pairs to find the list items. For this particular list of items, however, I can get an accurate number of items, but the value is always null! </p> <p>Using this:</p> <pre><code>TargetMidWindow.Content.ComponentType </code></pre> <p>I have discovered that the list I am having issues with is a 'listview' whereas the other windows I have had success with are 'detailslistview' in case it matters. Below is the code I have for finding the data I want, which is almost identical to my other successful code with the exception of altering the search terms I used. Also, in case its relevant, the program I'm trying to pull data out of is MetaTrader4, and I've been able to scrape data off other parts of the program successfully.</p> <pre><code> // Find the main window SystemWindow[] TopLevel = SystemWindow.AllToplevelWindows; SystemWindow TargetTopWindow = SystemWindow.ForegroundWindow; foreach (SystemWindow SearchWindow in TopLevel) { string Title = SearchWindow.Title; if (Title.Contains("MetaTrader")) { TargetTopWindow = SearchWindow; break; } } // Find the section where positions are contained SystemWindow[] MidLevel = TargetTopWindow.AllDescendantWindows; SystemWindow TargetMidWindow = SystemWindow.ForegroundWindow; foreach (SystemWindow SearchWindow in MidLevel) { string ClassName = SearchWindow.ClassName; if (ClassName.Contains("SysListView32")) { SystemWindow ParentWindow = SearchWindow.Parent; if ((ParentWindow.Title.Contains("Terminal"))) { TargetMidWindow = SearchWindow; } } } // Get the positions Dictionary&lt;string, string&gt; RawValues = new Dictionary&lt;string, string&gt;(); foreach (KeyValuePair&lt;string, string&gt; KVP in TargetMidWindow.Content.PropertyList) { string key = KVP.Key; string value = KVP.Value; } </code></pre> <p>Is there something special I need to do so that I do not get 'null' values for each list item?</p> <p>Thanks! Bill</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.
