Before you begin:
This code includes definitions for three classes: IconGroups, IconGroupResource and IconResource.

The IconGroups is a collection of the IconGroupResource objects. The icons property of the IconGroupResource class is a collection of the IconResource objects.

The following code employs classes from this code sample to store VFP Icon resources to ICO files.
oIconGroups = CREATEOBJECT("IconGroups",;
        _vfp.ServerName)

oIconGroups.EnumIconGroupResources
? "Icon groups:", oIconGroups.Count

LOCAL cTargetPath, nGroupIndex, nIconIndex
cTargetPath = GETDIR("", "Select ICO files destination folder.")

IF NOT EMPTY(m.cTargetPath)
        SET SAFETY OFF
        nGroupIndex = 0

        FOR EACH oIconGroup IN oIconGroups
                oIconGroup.SaveToFile(cTargetPath +;
                        "groupicon_" + TRANSFORM(nGroupIndex) + ".ico")

                nIconIndex = 0
                FOR EACH oIcon IN oIconGroup.icons
                        oIcon.SaveToFile(cTargetPath +;
                                "icon_" +;
                                TRANSFORM(nGroupIndex) + "_" +;
                                TRANSFORM(nIconIndex) + "_" +;
                                TRANSFORM(oIcon.resid) + ".ico")

                        nIconIndex = nIconIndex + 1
                NEXT
                nGroupIndex = nGroupIndex + 1
        NEXT
        SET SAFETY ON
ENDIF

    My comment:
    To see a variety of system icons, test this code with Shell32.dll and Imageres.dll files located in System32 folder.

    Storing DLL icon resources in .ICO files

    * * *
    VFP versions 3..9 do not support callback functions. This prevents using the EnumResourceNames function to enumerate available resources in executable or dynamic library files. For that reason, the IconGroups class enumerates IconGroup resources with only integer identifiers in 1..0xffff range.
