Cancelation of Refresh after Tab-Switch

[samot]

Following situation

I have three tabs with different directories open:
a) c:\temp
b) z:\ (network drive)
c) \\remotecomputer\c$

I'm working on a (local drive), while my network connection will got lost.

Now I switch the tab to b (the network drive) -> TC realize quickly, that I have no network connection and shows me my c-drive again (in the second tab).

But if I swicht to the third tab, the TC tries for at least an halfe minute to access the remote computer and I have to wait until it realize, that this path is not longer aviable (TC is blocked and not responding following to the task manager). It happens too, if the remote computer has no longer a network connection.

So it would be nice, if I could cancel the request simple by pressing the ESC-key.

best regards

Please try this: in wincmd.ini section [Configuration] add the line

ThreadFindFirst=1

It may or may not work, so please report what it does in your case!

[samot]

Thanks, it seems to work.

TC shows now after about 5 sec a small window "Connecting to ..." with a Cancel-Button. If I press it, it still shows me the remote path in the head line of the tab, but the file list is empty.

After several seconds TC realize, that it hasn't anything in the file list and ask me for another drive to show.

If I press it, it still shows me the remote path in the head line of the tab, but the file list is empty.

Can you change drive at this moment, e.g. to c:\ ?

[samot]

No, not until it shows me the c:\-drive (but it is much more faster, that I can work again as before).

Hmm, sounds like TC is still trying to access some remote path at this moment. Can you please check with filemon what is going on?

[samot]

OK, here is the FILEMON-Log.

Btw: Why does TC read the ini file every time I move my mouse from another application to TC and from TC to another appl.? Would it not make more sense to save the read entry in a global var?

Code: Select all

Interesting - I will check what options are read.

Christian, Vista supports cancellation of network I/O. So when you try to list files on a network share that is down, you should be able to cancel your request.

Does TC 7 include support for that?

[Genghis86]

From Mark Russinovich:

http://www.microsoft.com/technet/technetmag/issues/2007/02/VistaKernel/default.aspx

Probably the most visible change in the I/O system from an end-user perspective is Windows Vista support for canceling synchronous I/O operations. If you've ever performed a net view command or attempted to access a share to an off-line remote system using Windows XP or Windows Server® 2003, you've experienced the problems with I/O operations that can't be canceled: the command or file browser won't respond until a network timeout expires. An application has no choice but to wait until the operation fails because there's no way for it to tell the device driver executing the I/O that it doesn't care about the I/O anymore.

In Windows Vista most I/O operations can be canceled, including the open file I/O that Net View and Explorer use. Applications have to be updated to respond to end-user requests to cancel I/O, however, and many of the Windows Vista utilities that interact with devices that have timeouts have the necessary support. The file open and save dialogs that are used by virtually every Windows application, including third-party applications, for example, now enable their Cancel button while trying to display the contents of a folder. The Net command also cancels its synchronous I/O when you press Ctrl+C.

You can see the benefits of I/O cancellation by opening a command prompt on Windows Vista and typing:

net view \\nonexistentmachine

The command will hang while Windows tries to contact the nonexistent system, but you can type Ctrl+C to terminate it. In Windows XP, Ctrl+C has no effect and the command doesn't return until the network operation times out.

The APIs are described here:

I have seen this too, but it was not really necessary to use - I can just let the connection hang in the background. See the discussion in the English forum. But it would probably be an additional benefit. But I feat that some hardware drivers will crash when this function is called - driver support isn't very good yet on Vista.
