Hi!

I want to extract an icon from shell32.dll. (IconIndex = 72)
On WinXP, the 256 colored icon is loaded, on Win2000 and Win98, nothing is
loaded. The color depth on Win2000 and Win98 is higher than 256 colors.
Can You help me?

Best regards,
At

If you do :-

Hnd := ExtractIconEx( 'shell32.dll', -1, P1, P2, 1 );

Then Hnd returns the number of icons in the file

In my Win95 I get 72 returned
- which means that there are 0 to 71 icons

The documentation states that Hnd should return the handle to the
Icon, this seems wrong - 
Hnd := ExtractIconEx( 'shell32.dll', 71, P1, P2, 1 );

Returns 2 - which is the number of icons returned

I've tried to load the icon by name with LoadImage:

hSmallIcon := LoadImage(hShell32, PAnsiChar('154'), IMAGE_BITMAP, 16, 16,
LR_DEFAULTCOLOR + LR_SHARED);

GetLastError returns ERROR_RESOURCE_TYPE_NOT_FOUND

Why?

Just guessing: because it's not an IMAGE_BITMAP, it's an IMAGE_ICON?

Icons are not simple bitmaps, they are explicitly masked so portions
of it can be made invisible.
