The HTMLMAPPERDLGPARAMS structure provides information used to initialize the dialog box created by the L_DlgHTMLMapper function. After the user closes the dialog box, this structure is updated with information about the user's selections.
| Member | Description | |
| uStructSize | Size of this structure, in bytes. Use the sizeof operator to calculate this value. | |
| pBitmap | Pointer to the bitmap handle that references the bitmap used for preview or processing. | |
| bZoomToFit | Flag that indicates the initial zoom level for previewing the image. Possible values are: | |
| Value | Meaning | |
| TRUE | Set the initial zoom level to "Zoom to fit". | |
| FALSE | Set the initial zoom level to "Normal (1:1)". | |
| pURLEntries | Pointer to an array of DLGHISTORYLIST structures that contains URLs displayed in the URL History Combo Box in the dialog. These URLs may be associated with a specific area and activated when the user clicks on that area. This member can be NULL. Set this member to initialize the dialog. This member will be updated with the value entered by the user in the dialog. | |
| pALTEntries | Pointer to an array of DLGHISTORYLIST structures that contain information used in the ALT history combo box in the dialog. The ALT history combo box may be used to enter a short description of a specific area. Some browsers can display this text as a tool tip when the user hovers over the area. This parameter can be NULL. Set this member to initialize the dialog. This member will be updated with the value entered by the user in the dialog. | |
| pTargetEntries | Pointer to an array of DLGHISTORYLIST structures that contain information used in the Target history combo box in the dialog. The information in the Target combo box can be used to determine how the new page should be displayed. This parameter can be NULL. Set this member to initialize the dialog. This member will be updated with the value entered by the user in the dialog. | |
| pRolloverEntries | Pointer to an array of DLGHISTORYLIST structures that contain information used in the Rollover history combo box in the dialog. This parameter can be NULL. Set this member to initialize the dialog. This member will be updated with the value entered by the user in the dialog. | |
| uDlgFlags | User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are: | |
| Value | Meaning | |
| DLG_HTMLMAPPER_SHOW_CONTEXTHELP | [0x00000001] Dialog should contain a context sensitive help icon. | |
| pfnHelpCallback | Pointer to an optional help callback function. If you do not wish to provide help to this dialog, use NULL as the value of this parameter. To provide help to this dialog, use the function pointer as the value of this parameter. The callback function must adhere to the prototype described in LTCOMMDLGHELPCB. | |
| pHelpCallBackUserData | Void pointer that you can use to pass one or more additional parameters that the callback function needs. To use this feature, assign a value to a variable or create a structure that contains as many fields as you need. Then, in this parameter, pass the address of the variable or structure, casting it to L_VOID *. The callback function, which receives the address in its own pHelpCallBackUserData parameter, can cast it to a pointer of the appropriate data type to access your variable or structure. If the additional parameters are not needed, you can pass NULL in this parameter. | |
