This structure contains information about the target of an ALT+Tap event inside an HTML viewer control. The HTML viewer control passes the container application a pointer to an HTMLCONTEXT structure in the pnmHtmlContext parameter of the NM_CONTEXTMENU notification message.

Members
hdr
NMHDR structure, specifying the type of notification message being sent and identifying the control that sent it.
pt
Point that contains the screen coordinates of the event.
uTypeFlags
Desginates the type of object on which the user ALT+Tapped. It is one of the following values:
| Value | Description |
| HTMLCONTEXT_BACKGROUND | The target of the ALT+Tap event is a background object. This could be anything other than a link or an image. |
| HTMLCONTEXT_LINK | The target of the ALT+Tap event is an HTML link. |
| HTMLCONTEXT_IMAGE | The target of the ALT+Tap event is an image. |
| HTMLCONTEXT_IMAGENOTLOADED | The target of the ALT+Tap event is an image that has not been loaded yet. |
szLinkHREF
Null-terminated string that contains the URL of the link on which the user ALT+Tapped. The value in this member is only valid if the HTMLCONTEXT_LINK flag is set in the uTypeFlags member.
szImageSrc
Null-terminated string that contains the source URL of the image that is the target of the ALT+Tap event. The value in this member is only valid if the HTMLCONTEXT_IMAGE flag is set in the uTypeFlags member.
hbmImage
Handle to the bitmap associated with the image on which the user ALT+Tapped. The value in this member is only valid if the HTMLCONTEXT_IMAGE flag is set in the uTypeFlags member.
dwImageCookie
Specifies the cookie value that was originally passed from the application to the HTML viewer control in the dwCookie member of the INLINEIMAGEINFO structure referenced in the lParam of the DTM_SETIMAGE message. The value in this member is only valid if the HTMLCONTEXT_IMAGE flag is set in the uTypeFlags member.
Remarks
Never modify any of the data inside the HTMLCONTEXT structure. The HTML viewer control uses this data internally. Do not attempt to store or free any of the pointers contained in this structure. If you need to retain one of the strings for later use, make a copy of it.
