why do you code the WIN32 way in MFC, when MFC already have wrapper class, CAsyncSocket.

Hello,
I have this piece of code which i am using in my application developed on VS2003. i have migrated the code to VS2005 and have cleaned the code, but now i have to port it to Vista.
The code uses SHFILEOPSTRUCT and SHFileOperation which are nwo deprecated and a new interface IFileOperation has been introduced for Vista. I did a lot of head banging but still i could not figure out how to modify my code except the use of SetOperationFlag() function of IFileOperation. So please see if you could help.
Here are the snippets
<br />
SHFILEOPSTRUCT shfileop;<br />
<br />
shfileop.hwnd = NULL;<br />
<br />
shfileop.wFunc = FO_DELETE;<br />
<br />
shfileop.pFrom = pstrfrom;<br />
<br />
shfileop.pTo = NULL;<br />
<br />
shfileop.fFlags = FOF_NOCONFIRMATION;<br />
<br />
shfileop.fAnyOperationsAborted = 0;<br />
<br />
shfileop.hNameMappings = 0;<br />
<br />
shfileop.lpszProgressTitle = 0;<br />
<br />
SHFileOperation(&shfileop);
I get the pFrom and pTo from LPCTSTR type strings. I would also like to know about the double null termination of strings.
Thanks and regards,
Mustanseer

What does your code snippet have to do with using SetOperationFlag() or IFileOperation ?

But it should still work.
Mustanseer M S wrote: SHFileOperation(&shfileop);
What does this return?

Are they double-null terminated?

Hi Davis,
The code presented above was the one being used by me till i had my application compatible with XP or earlier. For Vista and later releases of Windows it is recommended to use IFileOperation interface instead of SHFileOperation(). That is why i want to replace SHFileOperation with IFileInterface.
As for the strings i am not sure whether they are double null terminated or not as i get them from a third party renderer. but i could double null terminate them using string maipulations if possible.
Any other suggestion will be welcomed.
Thank you for the trouble.
Regards,
Mustanseer

Ok, so what have you tried so far, and what results are you seeing?

SHFileOperation() will not work otherwise.

Hi, do you know how to delete multiple files at once? Thank you!

Hi,
what is the difference between MF_BYPOSITION and MF_BYCOMMAND in DeleteMenu() function of CMenu class.I have problem with MF_BYCOMMAND is not working properly.
|
|
|
|
|
From MSDN [^]:
MF_BYCOMMAND
Identifies menu item position by command.
[...]
MF_BYPOSITION
Identifies menu item position by zero-based relative position.
[...]
i.e. if you need to access the menu via its ID (like, for instance, IDM_EXIT ) then you have to specify MF_BYCOMMAND . Viceversa, if you want to specify the menu item via its position inside the menu then use MF_BYPOSITION )
Is it clear enough?

Hi,
I created a file in append mode using CreateFile();.But if I reopen the file add add string to it, it is appending from the starting of the file.
But it should be added from the end of the file.
What is wrong?
|
|
|
|
|
can u send ur code...so that i can get clearly.
Born to win...!

AFAIK CreateFile has no 'append' option: you have to go to the end of the file
(via SetFilePointer ) after opening it correctly for append (i.e. depending on your needs, with OPEN_ALWAYS or OPEN_EXISTING as dwCreationDisposition parameter) and start writing there.
