Combo/list box with icons/bmp/jpg/gif
Function CB_DrawImages
Select All      Help
function# hDlg message wParam lParam ctrlId $icons [flags] [imgWidth] [imgHeight] [dtFlags] ;;flags: 1 listbox (default combobox), 16 not icons (bmp, jpg, gif)

;Adds icons or bmp/jpg/gif images to a combo box or list box.

;This is what you have to do to create a combo or list box with icons or images:
;1. The dialog must be a smart dialog, ie with dialog function.
;2. In the dialog editor, add a combo or list box.
;3. In the Styles dialog:
;;;;For combo box, select CBS_OWNERDRAWFIXED and CBS_HASSTRINGS styles. Make sure that CBS_SORT is not selected (sorted combo boxes are not supported).
;;;;For list box, select LBS_OWNERDRAWFIXED and LBS_HASSTRINGS styles. Make sure that LBS_SORT is not selected (sorted list boxes are not supported).
;4. In the dialog function, insert CB_DrawImages before 'sel messages' line.

Similar code also can be used to draw owner-drawn controls of other types (those that support WM_DRAWITEM). Other control types also may require to process WM_MEASUREITEM.
CB_DrawImages hDlg message wParam lParam 4 "mouse.ico" 1

how can i add mouse.ico to each index, no matter how many there are?

I updated CB_DrawImages code here. Now your code will work.
thank you
Is it possible to reload the listbox (lb6) with other image and text data without having to restart the whole dialog?
With this function no. It creates imagelist when dialog starts, and cannot change it later.
Ok thanks!
