    <p>I have looked everywhere to see how to use Aero in my program. I fail to find any C function that previews the windows behind your own, like File Explorer or any mainstream browser does on their title bars. </p> <p>Some programs fake it by just adding an image that looks like the Windows 7 title bar -- without Aero -- but I consider it kind of cheating. I found this code on the link below:</p> <pre><code>[DllImport ("dwmapi.dll" Entry Point = "# 113", SetLastError = true)] internal static external DwmpActivateLivePreview uint (uint a, IntPtr b, uint c, uint d); [DllImport ("dwmapi.dll" Entry Point = "# 105", SetLastError = true)] internal static bool external DwmpStartOrStopFlip3D (); // Activate Aero peek into the desired Handle DwmpActivateLivePreview (1, Handle, 0, 1); // Disable Aero peek DwmpActivateLivePreview (0, Handle, 0, 1); // start or stop the Aero Flip 3D DwmpStartOrStopFlip3D (); </code></pre> <p>But have no idea what it means. Is the implementation of Aero Peek, automatically function with the <code>PreviewWindows(or whatever)</code> function?</p> <p>I'm lost.</p> <p><a href="http://www.jesconsultancy.nl/tips-and-tricks/aero-apis.html" rel="nofollow">This link</a> is in Dutch, just run it through Google Translate</p> <p>I am not trying to toggle whether or not Aero Peek and/or Flip is activated, or change the icon for my application when the mouse hovers on its taskbar icon. I am instead looking for a function that takes the current screen state of applications behind my own and returns it as an image for display in my application. As a bonus, does the (presumably) returned image come blurred, or is that effect that is separately applied? I think the name for it is Aero Glass.</p>

    1. COI'm still trying to figure out why this all works fine in C#, but I can't for the life of me get any working in C++ (via `LoadLibrary` and `GetProcAddress`).

    2. COAre you referring to the images that are returned when you mouse over their thumbnail previews and when you Alt+Tab between windows?

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.
