Extract Icons from exe applications or dlls -APIs- partII
We now studay icons exclusively with APIs.These APIs of course desserve the gdiplus and gdiplusX builts.
below 4 codes
1-extract icon given by an index in an exe or dll (icon is a valid one with a color depth=32)
2-Extract all icons 32x32 present in an exe or dll and save as ico in a given folder.
3.Extract with IconextractEx API the small or large icon from an icon
4-draw the windows standrad system icons on a form (showWindow=0,1,2).the drawing on a top level form having a particular hwn to accept drawings.
5-show explorer properties dialog box for any file (fired with the explorer rightclick on any file) with shell application method.
Notes:
-ExtractIconEx was not used in gdiplusX
-Can use same methods in previous post to view the icons on a form surface or IE browser application.can use also a listview control as pointed in Atoutfox link.
-below 5 codes around this chapter.

*Note: extractIcon API extracts only 32x32 format icons (color depth=32)
*this solves the pb of gdiplusX FUNCTION ExtractAssociatedIcon (for the icon representation) and got the valid icon format(can be embed in an image control and loaded with loadpicture() function).
