How To Use
Const FO_COPY = &H2
Const FOF_SIMPLEPROGR ESS = &H100 ' means don't show names of files
Dim foCopy As SHFILEOPSTRUCT
With foCopy
.wFunc = FO_COPY
.pFrom = "C:\Temp" & Chr(0) & Chr(0)
.pTo = "C:\Backup" & Chr(0) & Chr(0)
.fFlags = FOF_SIMPLEPROGR ESS

I am working on problem of coping folder.
I am using Windows XP/VB.Net 2003
I know how to do it with FileSystemObjec t, but I would like to have copy
dialog between operation like it is in windows explorer.
Is it possible to do this with System.IO (framework)?
I tried to use SHFileOperation (SHFileOP), but something is wrong.
After setting SHFileOp structure like
With SHFileOp
.wFunc = FO_COPY
.pFrom = "C:\Temp" & Chr(0) & Chr(0)
.pTo = "C:\Backup" & Chr(0) & Chr(0)
.fFlags = FOF_SIMPLEPROGR ESS
End With
my program stop with:
An unhandled exception of type 'System.NullRef erenceException ' occurred in
xxx.exe
Additional information: Object reference not set to an instance of an
object.
I don't know where is the problem.
Thanks all for help!!!
Simon
