Detailed Description

This structure is used by HLN_LOAD_DATA notification.

Notifies that HtmLayout is about to download a referred resource.

Parameters:

lParam

LPNMHL_LOAD_DATA.

Returns:

LOAD_OK or LOAD_DISCARD

This notification gives application a chance to override built-in loader and implement loading of resources in its own way (for example images may be loaded from database or other resource). To do this set NMHL_LOAD_DATA::outData and NMHL_LOAD_DATA::outDataSize members of NMHL_LOAD_DATA. HTMLayout does not store pointer to this data. You can call HTMLayoutDataReady() function instead of filling these fields. This allows you to free your outData buffer immediately.
