Hi Mike,

During paring through Microsoft Bluetooth driver, I am getting this error.

Please suggest me something.

Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))

Hi Mike,

I am calling wclFTPClient.dir() from the wclFTP_DirCompletedEvent()

but the wclOBEXDirCompleteEventArgs is not changing. Please suggest me something.

wclOBEXDirCompleteEventArg returns the same file listing every time. What may be the problem ?

[Mike Petrichenko]

It works completly correct. You are in directory and call Dir method to list files in this directory. After listing done (inside event handler) you call Dir again and get the listing in the same directory again. So it will never change.

[Raj]

Inside event handler I am doing.

1> Set the path.
2> Set a flag.

In the operationcompleted event calling dir again.

according to the flag doing something and as I have set the path previously now dircompleted event handler should return the new list of files and folders.

[Mike Petrichenko]

Yes, if setpath operation completes with WCL_ERROR_SUCCESS then dir will return new list, otherwise the path is not changed.

[Raj]

thanks for your support, I have resolved the problem.

I am not setting the path correctly

[Mike Petrichenko]

You are welcome!

Hi Mike,

Why the file count is returned 0 sometimes for an connected device.
However when I restart the application then the file count > 0

Can you suggest me the possible error.
So that I can resolve.

[Mike Petrichenko]

May be your application changes current directory and the new one is empty?

[Raj]

No my application does not changes any directory. I am making the array list of current file path, and the array list is showing me the correct path.

[Mike Petrichenko]

Show your code which works with directories.
