1) What API are you using?
2) Does the method perform it's function?
3) What error code is returned by GetLastError WinAPI function?


Sincerely yours

1) .net 2.0
2) No, no refresh in explorer
3) 183 - ERROR_ALREADY_EXISTS - Cannot create a file when that file already exists

Thank you, the developers are investigating the possible problem. It would be great if you also specified the OS you are doing the test on.

This function cannot be called from the callback thread context. It's quite possible this is a reason of the problem.
Also could you please specify your code chunk where the function is called?

Hello,

Thanks for replays.

I have .net API and there is a event DirChanged.
This API is used by 2 applications, One is desktop CRM, Second CallBackDriver windows service.

When I'm adding file in CRM App, the event is generated and in CallBackService some method is invoked, there I'm using Your Notify function.

ShellApi.shellService.OnChanged += new ShellService.RefreshEventDelegate(ShellServiceRefreshEvent);

private void ShellServiceRefreshEvent(string target)
{
if (!cbFS.NotifyDirectoryChange(target, CbFsNotifyFileAction.fanAdded))
{
logger.Info("FS Notify failed " + string.Concat(ShellManager.Instance.FILESYSTEM_LETTER, target));
}
}

And what the OS version (including does it 32 or 64-bit) are you using?

Thanks.

Hello,

You must specify a file or directory name that was added to its parent directory. And this name must be without drive letter. For example: "\Home\file.txt".
CallbackFS Help has a mistake in the CallbackFileSystem.NotifyDirectoryChange method description for its first parameter. We will fix it.
