You can add a standard control to a form in two ways: using a resource file, or creating an instance of a control with CoCreateInstance. With resource files, constraint-based layout is supported. Constraint-based layout enables you to program a UI that is more flexible than a layout programmed using CoCreateInstance. To use constraint-based layout, define the control in a resource file, then load the resource file.
Auto PC standard controls adhere to the ActiveX automation model and can be used by any ActiveX client. However, conventional ActiveX in-place activation and embedding are not supported by Windows CE for the Auto PC.
