xcall DOTNET_TKADDCTL(window_id, object[, flags])
Arguments
window_id
The ID of a window created by %DOTNET_TKWIN. (Otherwise Toolkit throws an exception.) (n)
object
The .NET form, .NET control, or WPF element to add. This must be derived from System.Windows.Forms.Form, System.Windows.Forms.Control, or System.Windows.UIElement. If object is null or does not wrap a .NET form, .NET control or WPF element, Toolkit throws an exception. (@DotNetObject)
flags
(optional) Pass as DN_WPF if object is a WPF element; otherwise omit this argument. (n)
Discussion
DOTNET_TKADDCTL adds a .NET form, a .NET control, or a WPF element to the Controls collection for a previously embedded .NET form (contained in window_id), but it does not adjust its size or position. (On UNIX and OpenVMS, this routine merely returns.)
To add a WPF element, pass flags as DN_WPF. If you pass flags as DN_WPF, object must be a WPF element (i.e., it must be instantiated from a class derived from System.Windows.UIElement); otherwise a DotNetException will be thrown.

%DOTNET_TKWIN routine for information on embedding a .NET form in a Toolkit window
This example adds two .NET controls (a label and a field) to a composite window and processes the composite window. Toolkit automatically creates a .NET form for the controls. See step 1 of Embedding a .NET form.
