Hello,
The File.Delete(VS2005) function can not delete file on Vista-64bit, why?

And, what changes of API between 32-bit and 64-bit?

Thank you
 
Yes, i have the permission(Right-Click the exe file, choose the Run as
Administrator), even i closed the UAC function.
 
Sorry, the io.file.delete works well, but the API below for x86 will not
work on x64, how to change the API to x64?

Hi,

Try using an intptr for the hwnd in the structure. A handle is
not the same size in a 64bit os as a 32bit one.


Private Structure SHFILEOPSTRUCT
Dim hWnd As intptr

Ken
 
Could you please view the API below, them will not work on 64bit.
I have change the
Dim hwnd As Integer
to
Dim hwnd As Intptr, but it will not work yet.
Thank you
