icons - concatenate in memory

help - I need to concatenate multiple icons from the apps resource file into one wider icon that is created in memory and then displayed.

the number of icons being concatenated varies and are of different images.

hicon1 = LoadIcon(hInst,aIcon1);
hicon2 = LoadIcon(hInst,aIcon2);
hicon3 = LoadIcon(hInst,aIcon3);
hicon4 = LoadIcon(hInst,aIcon4);
hicon5 = LoadIcon(hInst,aIcon5);
...

based on a selection i need to concatenate the icons to create hIconNew
all icons are 16x16 in size.

create new icon where hIconNew = hIcon1 + hIcon3 + hIcon4; (how icons will be displayed .. one after another).
or
another time i may need to display
hIconNew = hIcon2+hIcon5;

then with new icon handle call

SendMessage(hWnd,SB_SETICON,0,(LPARAM)hIconNew);

Does any one know how to do this??

Thanks,
Art

Load the icons.
Create a memory DC and select in it a bitmap having the size of the concatenated image.
Use DrawIcon to draw your icons in the memory DC at the desired positions.
