Detailed Description

This structure is used by HLN_CREATE_CONTROL and HLN_CONTROL_CREATED notifications.

• HLN_CREATE_CONTROL This notification is sent on parsing the document and while handling <INPUT>, <TEXTAREA>, <SELECT> and <WIDGET> tags.

  Parameters:

  lParam

  LPNMHL_CREATE_CONTROL.

  Returns:

  HWND of the control or HWND_TRY_DEFAULT or HWND_DISCARD_CREATION.

  This notification is sent when HtmLayout is about to create a child control. The application can override the creation of "standard HTML controls" or implement the creation of other application specific controls. To do this assign HWND of newly created control to NMHL_CREATE_CONTROL::outControlHwnd member of NMHL_CREATE_CONTROL.

• HLN_CONTROL_CREATED This notification is sent when control creation process has completed.

  Parameters:

  lParam

  LPNMHL_CREATE_CONTROL.

  While processing this notification application can modify control settings or store information about the created control. For example it can use SetWindowLong() function, to set control's id:

   SetWindowLong(((LPNMHL_CREATECONTROL)lParam)->outControlHwnd, GWL_ID, controlId)
