Shell's SHFileOperation

[vfpshe]

Can somebody please please help me with this function. I've been trying to use this function to copy folders from one location to another. I was thinking of using this because of the animated progress bar and status info. it provides while copying.

Here's part of my code:

Declare INTEGER SHFileOperation IN Shell32.dll SHFILEOPSTRUCT

PUBLIC oFileStruct
oFileStruct = CREATEOBJECT([SHFILEOPSTRUCT])

WITH oFileStruct
.hwnd = Thisform.HWnd
.wFunc = 0x2 &&[fo_copy]
.pfrom = [c:\dummy\*.*]
.pTo = [c:\documents\dummy]
.fFlags = 0x100
ENDWITH

=SHFileOperation(oFileStruct)

DEFINE CLASS SHFILEOPSTRUCT AS Custom
hwnd = 0
wFunc = 0
pFrom = ''
pTo = ''
fFlags = 0
fAnyOperationsAborted = 0
hNameMappings = 0
lpszProgressTitle = ''
ENDDEFINE

~~~~~~~~~~~~~~~~~~~

This just doesn't seem to work.. it give me a 'too many argument' message.. please help!

VFP doesn't support &quot;structures&quot; for API calls directly, so you will need to build a string that &quot;looks&quot; like the structure to this DLL. While you can do this manually <s>, you may be better off getting a class that can do this for you. Go to the UT (

http://www.universalthread.com/),

click on the Download picture on the leftt, and choose the Visual FoxPro area. Next enter 'struct' (without the quotes) in the Title area and press Enter. You should get back an entry for:
struct.zip - &quot;A Visual FoxPro class to simplify packing and unpacking of structures for use WINAPI functions or other DLLs Code is included.&quot;
There is excellent documentation on it's use in a .DOC file.
