<dl>
<dt>
<b>Function</b>
<dd>
Executes a User Language Dialog.
<p>
<dt>
<b>Syntax</b>
<dd>
<tt>int dlgDialog(string Title) <i>block</i> ;</tt>
<p>
<dt>
<b>Returns</b>
<dd>
The <tt>dlgDialog</tt> function returns an integer value that can be given a user defined meaning
through a call to the <tt><a href=313.htm>dlgAccept()</a></tt> function.<br>
If the dialog is simply closed, the return value will be <tt>0</tt>.
<p>
<dt>
<b>Description</b>
<dd>
The <tt>dlgDialog</tt> function executes the dialog defined by
<tt><a href=216.htm>block</a></tt>.
This is the only dialog object that actually is a User Language builtin
function. Therefore it can be used anywhere where a function call is allowed.
<p>
The <tt>block</tt> normally contains only other <a href=287.htm>dialog objects</a>,
but it is also possible to use other User Language statements, for example to conditionally add
objects to the dialog (see the second example below).
<p>
By default a <tt>dlgDialog</tt> contains a <a href=310.htm>dlgVBoxLayout</a>,
so a simple dialog doesn't have to worry about the layout.
<p>
A <tt>dlgDialog</tt> should at some point contain a call to the <tt><a href=313.htm>dlgAccept()</a></tt>
function in order to allow the user to close the dialog and accept its contents.
<p>
If all you need is a simple message box or file dialog you might want to use one of the
<a href=283.htm>Predefined Dialogs</a> instead.
