    <p>I have a Delphi project and the main form is a child window of another application. The parent application (a 3D game coded in C++) has two window states, <strong>windowed</strong> and <strong>full screen</strong>. In windowed mode the Delphi form floats on top of the parent application perfectly. It can be clicked on, dragged around, no problem (using <strong>params.Style := WS_POPUP;</strong> in the CreateParams procedure of my main form):</p> <pre><code>procedure TMyForm.CreateParams(var Params: TCreateParams); begin inherited CreateParams(Params); HandleToTheOtherApp := FindWindow('THE_OTHER_APP', nil); if HandleToTheOtherApp = 0 then begin ShowMessage('The parent app was not found'); exit; end; params.Style := WS_POPUP; params.WndParent := HandleToTheOtherApp; params.WinClassName := 'MyAppClassName'; end; </code></pre> <p>However if the parent application is put into <strong>full screen</strong> mode (it uses DirectX 9/10) my Delphi form is hidden from view. It appears to still be on the screen as I can see if flashing occasionally, but is not being redrawn. </p> <p>If I click on the window (or where it appears to be) it re-appears for a second and then dumps the game out of full screen mode and back into windowed mode. Clearly there is something it doesn't like about the form. The form <strong>used</strong> to appear in previous editions of this game, but perhaps due to changes in the DirectX version (my guess) it no longer appears.</p> <p>The form doesn't display anything complicated like 3D graphics, just basic controls like buttons and list boxes. I have tried various Window styles and made it Doublebuffered, all to no avail. Perhaps there is someone out there who has been successful in getting a window to show in these circumstances using a particular function, Window style or header?</p> <p>Is there some way to make a Delphi form appear correctly within a DirectX environment?</p>

    1. COI'm not aware of any full-screen game that's capable of coexisting with a windowed app. Even if I'm running full-screen on one monitor and click on a windowed app in my other one, it dumps the game out of full-screen when it loses focus. I think it's a limitation of 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.
