    <p>Use the <a href="http://msdn.microsoft.com/en-us/library/bb776292.aspx" rel="noreferrer">autocompletion feature</a> built in to all Windows edit controls.</p> <p>First, fill your <code>TStrings</code> object however you want. Then use <a href="http://docwiki.embarcadero.com/VCL/en/AxCtrls.GetOleStrings" rel="noreferrer"><code>GetOleStrings</code></a> to create a <a href="http://docwiki.embarcadero.com/VCL/en/AxCtrls.TStringsAdapter" rel="noreferrer"><code>TStringsAdapter</code></a> to wrap it. (The adapter does not claim ownership of the <code>TStrings</code> object, so you must make sure you don't destroy it while the adapter is still live.) The adapter gives you an <code>IStrings</code> interface, which you'll need because the autocompletion feature requires an <a href="http://msdn.microsoft.com/en-us/library/ms687257.aspx" rel="noreferrer"><code>IEnumString</code></a> interface to provide the completion matches. Call <a href="http://docwiki.embarcadero.com/VCL/en/AxCtrls.TStringsAdapter._NewEnum" rel="noreferrer"><code>_NewEnum</code></a> for that.</p> <p>Next, call <a href="http://msdn.microsoft.com/en-us/library/ms686615.aspx" rel="noreferrer"><code>CoCreateInstance</code></a> to create an <a href="http://msdn.microsoft.com/en-us/library/bb776292.aspx" rel="noreferrer"><code>IAutoComplete</code></a> object. Call its <a href="http://msdn.microsoft.com/en-us/library/bb776293.aspx" rel="noreferrer"><code>Init</code></a> method to associate it with the window handle of your edit control. If you're using a combo box, then send it a <a href="http://msdn.microsoft.com/en-us/library/bb775772.aspx" rel="noreferrer"><code>cbem_GetEditControl</code></a> message to find the underlying edit window.</p> <p>You can stop at that point and autocompletion should work automatically. You can disable autocompletion if you want, or you can set any number of <a href="http://msdn.microsoft.com/en-us/library/bb762479.aspx" rel="noreferrer">autocompletion options</a>.</p> <p>You say you don't want autocompletion, but in the OS terminology, I think what you really don't want is called <strong>auto append</strong>, where the remainder of the string is entered into the edit box automatically as the user types, but selected so that further typing will overwrite it, and the user needs to delete the excess text if the desired value is shorter than one of the matches. </p> <p>There is also <strong>auto suggest</strong>, which displays a drop-down list of suggestions. </p> <p>You can enable either or both options. You don't need to filter the list of suggestions yourself; the autocomplete object filters the <code>IEnumString</code> list by itself.</p>

    1. COThis is nothing short of perfect, precisely what I want, I wasn't aware of autocompletion options, thanks.

    2. COIAutoComplete doesn't seem to support matching of any partial string, but only supports matching from the start. I mean, given two strings, 'bcd' and 'abcd', if I type 'bc', only 'bcd' will be matched, but I also want 'abcd' to be matched also.

    3. COThen "autocomplete" isn't the feature you wanted in the first place, @Edwin. It *completes* what you've already typed.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
