System_CAPS_importantImportant

This function cannot be used in applications that execute in the Windows Runtime.


      ATLAPI AtlAxCreateControlEx(
LPCOLESTR lpszName,
HWND hWnd,
IStream* pStream,
IUnknown** ppUnkContainer,
IUnknown** ppUnkControl,
REFIID iidSink = IID_NULL,
IUnknown* punkSink = NULL
);

lpszName

A pointer to a string to be passed to the control. Must be formatted in one of the following ways:

  • A ProgID such as "MSCAL.Calendar.7"

  • A CLSID such as "{8E27C92B-1264-101C-8A2F-040224009C02}"

  • A URL such as "http://www.microsoft.com"

  • A reference to an Active document such as "file://\\Documents\MyDoc.doc"

  • A fragment of HTML such as "MSHTML:<HTML><BODY>This is a line of text</BODY></HTML>"

    System_CAPS_noteNote

    "MSHTML:" must precede the HTML fragment so that it is designated as being an MSHTML stream.

hWnd

[in] Handle to the window that the control will be attached to.

pStream

[in] A pointer to a stream that is used to initialize the properties of the control. Can be NULL.

ppUnkContainer

[out] The address of a pointer that will receive the IUnknown of the container. Can be NULL.

ppUnkControl

[out] The address of a pointer that will receive the IUnknown of the created control. Can be NULL.

iidSink

The interface identifier of an outgoing interface on the contained object.

punkSink

A pointer to the IUnknown interface of the sink object to be connected to the connection point specified by iidSink on the contained object after the contained object has been successfully created.

One of the standard HRESULT values.

AtlAxCreateControlEx is similar to AtlAxCreateControl but also allows you to receive an interface pointer to the newly created control and set up an event sink to receive events fired by the control.

To create a licensed ActiveX control, see AtlAxCreateControlLicEx.
